  8. Digital printing

    Sobotka, Werner K.

    1997-02-01

    Digital printing is described as a tool to replace conventional printing machines completely. Still this goal was not reached until now with any of the digital printing technologies to be described in the paper. Productivity and costs are still the main parameters and are not really solved until now. Quality in digital printing is no problem anymore. Definition of digital printing is to transfer digital datas directly on the paper surface. This step can be carried out directly or with the use of an intermediate image carrier. Keywords in digital printing are: computer- to-press; erasable image carrier; image carrier with memory. Digital printing is also the logical development of the new digital area as it is pointed out in Nicholas Negropotes book 'Being Digital' and also the answer to networking and Internet technologies. Creating images text and color in one country and publishing the datas in another country or continent is the main advantage. Printing on demand another big advantage and last but not least personalization the last big advantage. Costs and being able to coop with this new world of prepress technology is the biggest disadvantage. Therefore the very optimistic growth rates for the next few years are really nonexistent. The development of complete new markets is too slow and the replacing of old markets is too small.

  19. Processless offset printing plates

    Directory of Open Access Journals (Sweden)

    Sanja Mahović Poljaček

    2015-06-01

    Full Text Available With the implementation of platesetters in the offset printing plate making process, imaging of the printing plate became more stable and ensured increase of the printing plate quality. But as the chemical processing of the printing plates still highly influences the plate making process and the graphic reproduction workflow, development of printing plates that do not require chemical processing for offset printing technique has been one of the top interests in graphic technology in the last few years. The main reason for that came from the user experience, where majority of the problems with plate making process could be connected with the chemical processing of the printing plate. Furthermore, increased environmental standards lead to reducing of the chemicals used in the industrial processes. Considering these facts, different types of offset printing plates have been introduced to the market today. This paper presents some of the processless printing plates.

    Grant, Maria J

    2013-12-01

    The chances are the first thing you when you set out to write an article is the title. But what factors transform a mediocre title into a good title? Firstly, it should be both informative and specific, using words or phrases likely to be used when searching for information, for example 'nurse education' rather than simply 'nurse'. Secondly, it should be concise yet convey the main ideas clearly; articles with short titles reporting study findings have been found to attract higher numbers of viewing and citations. Thirdly, provide details of the study design to assist the reader in making an informed choice about the type of project your article is reporting. In taking these small steps when developing your title, your title can present a more concise, retrievable and clear articulation of your article.

    LaDou, Joseph

    2006-05-01

    The printed circuit board is the platform upon which microelectronic components such as semiconductor chips and capacitors are mounted. It provides the electrical interconnections between components and is found in virtually all electronics products. Once considered low technology, the printed circuit board is evolving into a high-technology product. Printed circuit board manufacturing is highly complicated, requiring large equipment investments and over 50 process steps. Many of the high-speed, miniaturized printed circuit boards are now manufactured in cleanrooms with the same health and safety problems posed by other microelectronics manufacturing. Asia produces three-fourths of the world's printed circuit boards. In Asian countries, glycol ethers are the major solvents used in the printed circuit board industry. Large quantities of hazardous chemicals such as formaldehyde, dimethylformamide, and lead are used by the printed circuit board industry. For decades, chemically intensive and often sloppy manufacturing processes exposed tens of thousands of workers to a large number of chemicals that are now known to be reproductive toxicants and carcinogens. The printed circuit board industry has exposed workers to high doses of toxic metals, solvents, acids, and photolithographic chemicals. Only recently has there been any serious effort to diminish the quantity of lead distributed worldwide by the printed circuit board industry. Billions of electronics products have been discarded in every region of the world. This paper summarizes recent regulatory and enforcement efforts.

    Full Text Available Printing will also be done in the future. Printed items meet basic needs and are deeply anchored in people’s habits. Being able to handle and collect printed matter is highly attractive. And paper is now more alive than ever. It is therefore too shortsighted to disclaim the importance of one of the still large economic sectors just because of a few looming-recession instigated market shifts.The exciting aspect of drupa 2004 is: printing will be reinvented, so to speak. Much more printing will be done in the future than at present. On the one hand, people are concentrating on process optimization and automation to ensure this. Measuring and testing, process control and optimization, and linking up "office software" with printing technology will be very central topics at drupa 2004. Electronics and print are not rivals; a symbiosis exists. And printing is high-tech: hardly any other multifaceted sector which has been so successful for centuries is as computerized as the printing industry.A series of "new chapters" in the variety of printing possibilities will be opened at drupa. Talk will be generated by further technical developments, often the connection between paper/cardboard and electronics, the link between the office world and graphics industry, text databases and their link-up to graphic page production tools, and "on the fly" dynamic printing over networks.All of this and more belongs to future potentialities, which are so substantial overall, the outlook is by no means black for the "black art". Like its predecessors, drupa 2004 is also a product trade fair. However, more than ever before in its history, it is also an "information village". The exhibits are useful, because they occasionally make what this means visible.

    In the last five years, research on memristive devices has been under ever increasing interest. Additionally, recent development in printed techniques provides new approaches to fabricate also memristive devices in inexpensive and flexible manner. Thus their research is an important effort towards fully printed electronics applications. In this work, an organometallic precursor solution for a memristive layer was synthesised and formulated for inkjet-printable form. Layers of the solution were determined with surface profilometry in order to find feasible layer thickness for memristive behaviour. Memristors were inkjet-printed on copper- and titanium-coated glass sheets, and various heat-treatments were carried out. The influence of the heat-treatments on the durability and resistance values of the memristors was evaluated. Microstructural and phase changes in the memristive layer were observed with X-ray diffraction and field emission scanning electron microscopy analysis.

    2012-01-01

    This study explored relations of print exposure, academic achievement, and reading habits among 100 deaf and 100 hearing college students. As in earlier studies, recognition tests for book titles and magazine titles were used as measures of print exposure, college entrance test scores were used as measures of academic achievement, and students provided self-reports of reading habits. Deaf students recognized fewer magazine titles and fewer book titles appropriate for reading levels from kindergarten through Grade 12 while reporting more weekly hours of reading. As in previous studies with hearing college students, the title recognition test proved a better predictor of deaf and hearing students' English achievement than how many hours they reported reading. The finding that the recognition tests were relatively more potent predictors of achievement for deaf students than hearing students may reflect the fact that deaf students often obtain less information through incidental learning and classroom presentations.

  11. Facing Title V permit constraints

    Energy Technology Data Exchange (ETDEWEB)

    Patankar, U.M. [JACA Corp., Fort Washington, PA (United States)

    1995-06-01

    The new Title V operating permit requirement under state regulations pursuant to the 1990 Clean Air Act Amendments will cover every emission source at a facility. These rules will significantly affect an operation by setting minimum compliance requirements, mandating periodic compliance certification, prescribing complex monitoring, record keeping and reporting procedures and making state and EPA approval of routine operational changes necessary through a permit amendment. The main concern with Title V is its effect on the operational flexibility of a facility, and individual emission sources within that facility. Unless properly addressed in a permit document, the term operational flexibility, so freely used by regulators in the context of the Title V program, can turn into a misnomer and the ability to operate as before may be significantly compromised under Title V. True operational flexibility is essential for businesses to respond to real changes in the marketplace. In the age of automation, just-in-time inventories and increased competition, flexibility to operate can mean the difference between growth and stagnation.

  12. Printed Spacecraft Separation System

    Holmans, Walter [Planetary Systems Corporation, Silver Springs, MD (United States); Dehoff, Ryan [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)

    2016-10-01

    In this project Planetary Systems Corporation proposed utilizing additive manufacturing (3D printing) to manufacture a titanium spacecraft separation system for commercial and US government customers to realize a 90% reduction in the cost and energy. These savings were demonstrated via “printing-in” many of the parts and sub-assemblies into one part, thus greatly reducing the labor associated with design, procurement, assembly and calibration of mechanisms. Planetary Systems Corporation redesigned several of the components of the separation system based on additive manufacturing principles including geometric flexibility and the ability to fabricate complex designs, ability to combine multiple parts of an assembly into a single component, and the ability to optimize design for specific mechanical property targets. Shock absorption was specifically targeted and requirements were established to attenuate damage to the Lightband system from shock of initiation. Planetary Systems Corporation redesigned components based on these requirements and sent the designs to Oak Ridge National Laboratory to be printed. ORNL printed the parts using the Arcam electron beam melting technology based on the desire for the parts to be fabricated from Ti-6Al-4V based on the weight and mechanical performance of the material. A second set of components was fabricated from stainless steel material on the Renishaw laser powder bed technology due to the improved geometric accuracy, surface finish, and wear resistance of the material. Planetary Systems Corporation evaluated these components and determined that 3D printing is potentially a viable method for achieving significant cost and savings metrics.

  13. Printing at CERN

    CERN Multimedia

    Otto, R

    2007-01-01

    For many years CERN had a very sophisticated print server infrastructure which supported several different protocols (AppleTalk, IPX and TCP/IP) and many different printing standards. Today’s situation differs a lot: we have a much more homogenous network infrastructure, where TCP/IP is used everywhere and we have less printer models, which almost all work using current standards (i.e. they all provide PostScript drivers). This change gave us the possibility to review the printing architecture aiming at simplifying the infrastructure in order to achieve full automation of the service. The new infrastructure offers both: LPD service exposing print queues to Linux and Mac OS X computers and native printing for Windows based clients. The printer driver distribution is automatic and native on Windows and automated by custom mechanisms on Linux, where the appropriate Foomatic drivers are configured. Also the process of printer registration and queue creation is completely automated following the printer regis...

    This paper presents research activities carried out at VTT Technical Research Centre of Finland in the field of hybrid integration of optics, electronics and mechanics. Main focus area in our research is the manufacturing of electronic modules and product structures with printed electronics, film-over-molding and polymer sheet lamination technologies and the goal is in the next generation of smart systems utilizing monolithic polymer packages. The combination of manufacturing technologies such as roll-to-roll -printing, injection molding and traditional component assembly is called Printed Hybrid Systems (PHS). Several demonstrator structures have been made, which show the potential of polymer packaging technology. One demonstrator example is a laminated structure with embedded LED chips. Element thickness is only 0.3mm and the flexible stack of foils can be bent in two directions after assembly process and was shaped curved using heat and pressure. The combination of printed flexible circuit boards and injection molding has also been demonstrated with several functional modules. The demonstrators illustrate the potential of origami electronics, which can be cut and folded to 3D shapes. It shows that several manufacturing process steps can be eliminated by Printed Hybrid Systems technology. The main benefits of this combination are small size, ruggedness and conformality. The devices are ideally suited for medical applications as the sensitive electronic components are well protected inside the plastic and the structures can be cleaned easily due to the fact that they have no joints or seams that can accumulate dirt or bacteria.

    The use of printed electronics technologies (PETs), 2D or 3D printing approaches either by conventional electronic fabrication or by rapid graphic printing of organic or nonorganic electronic devices on various small or large rigid or flexible substrates, is projected to grow exponentially in commercial industry. This has provided an opportunity to determine whether or not PETs could be applicable for low volume and high-reliability applications. This report presents a summary of literature surveyed and provides a body of knowledge (BOK) gathered on the current status of organic and printed electronics technologies. It reviews three key industry roadmaps- on this subject-OE-A, ITRS, and iNEMI-each with a different name identification for this emerging technology. This followed by a brief review of the status of the industry on standard development for this technology, including IEEE and IPC specifications. The report concludes with key technologies and applications and provides a technology hierarchy similar to those of conventional microelectronics for electronics packaging. Understanding key technology roadmaps, parameters, and applications is important when judicially selecting and narrowing the follow-up of new and emerging applicable technologies for evaluation, as well as the low risk insertion of organic, large area, and printed electronics.

  16. Influence of the Print Run on Silver Halide Printing Plates

    Full Text Available The most common printing technique today is lithography. The difference between printing and nonprinting areason a printing plate is accomplished by opposite physical and chemical properties of those areas (MacPhee, 1998.The printing areas are made of photoactive layer that attracts oil and chemical substances with oil solvent – printinginks. The nonprinting areas are made of aluminium-oxide which attracts water based substances – the fountainsolution.There are many of various types of photoactive layer which are used for production of offset printing plates, amongothers is silver halide layer. The usage of the silver halide technology in the graphic reproduction is not a novelty.The filmmaking phase is based on the usage of the silver halide as the photographically active ingredient, for instance,AgBr (silver bromide. The new, digital plate making technology (Computer to Plate, CtP eliminates thefilmmaking phase and therefore enables control of the printing plate’s exposure made by computer. CtP technologyeliminates the filmmaking phase, but it also results with the reduction of needed material quantities and requiredtime for the production (Limburg, 1994; Seydel, 1996.In this paper the basis of the graphic reproduction by using the silver halide digital printing plates was described.The changes of the AgX copying layer and the surface of the aluminium base in the printing process have beenobserved. The surface characteristics were determined by measuring the relevant surface roughness parameters. Inaddition, measurements of coverage values on the prints, detailed at smaller print run, were conducted.Results showed that surface changes on the printing plate are changing during printing process and that thesechanges influence transfer of the printing ink on the printing substrate. These measurements proved to be of greatinterest in the graphic reproduction as they enable us to determine consistency of the printing plates during theprinting

    Have you ever hesitated to print a confidential document using CERN printers? Or perhaps you have rushed quickly to the printer after hitting the “print” button in order to avoid someone else getting hold of and reading your document? These times are over now with the new printing infrastructure!   Indeed, many of us regularly print out confidential documents like our salary slips, MARS forms, tendering documents and drafts of preliminary papers. The upcoming CERN data protection policy will require all of us to respect the confidentiality of such documents and, as the word “confidential” implies, access to “confidential” or sensitive documents will be tightly controlled. What can we do about the public printers located in many buildings, floors and shared spaces - accessible not only to CERN staff and users but also to visitors and guests? Some printers are located in the vicinity of restaurants, cafeterias or close to paths taken b...

    With digital camera adoptions going main stream, consumers capture a record number of photos.Currently, the majority of the digital photos are printed at home. One of the key enablers of this transformation is the advancement of home photo printing technologies. In the past few years, inkjet printing technologies have continued to deliver smaller drop size, larger number of inks, and longer-lasting prints. In the mean time, advanced image processing automatically enhances captured digital photos while being printed. The combination of the above two forces has closed the gap between the home photo prints and AgX prints. It will give an overview of the home photo printing market and technology trends, and discuss major advancements in automatic image processing.

The proposed method eliminates those critical disadvantages of solvent-based printing techniques by taking the advantages of electroless deposition and laser printing. The synthesized toner acts as a catalyst for the electroless copper deposition as well as an adhesion-promoting buffer layer between the substrate and deposited copper. The easy metallization of printed patterns and strong metal-substrate adhesion make it an especially effective method for massive production of flexible printed circuits. The proposed process is a high throughput, low cost, efficient, and environmentally benign method for flexible electronics manufacturing.

The information processing begins with the information receiving, then the preparation for printing, then printing itself and finally finishing the processed information. Of course, during these four steps, specially some prints are imperilled and have to be protected. An investigation was performed to establish the state of information imperilling in printing, in 96 companies with 498 interviewed persons. The questionnaire comprised 26 questions and 130 variables.The poll has shown the state of imperilling, specially the information protection in printing, with the aim to improve the protection measures. The investigation results can be used as the model for organizing the protection in printing companies.

  17. CBM split title in Alberta

    Energy Technology Data Exchange (ETDEWEB)

    Campbell, L.M. [EnCana Corp., Calgary, AB (Canada); Laurin, W.

    2006-07-01

    Coalbed methane (CBM) coal underlies most of central and southern Alberta. This article discussed disputes surrounding CBM ownership and split-titles. Historically, ownership of lands in Alberta implied possession and rights of all under- and overground substances. Surface estates are now typically separated from the subsurface estate, and subsurface estates are further divided either on the basis of substances or stratigraphically to create a split-title. Mineral severances are used to separate respective mineral rights among owners. While there is a relative certainty that under provincial Crown tenure CBM is included in natural gas tenure, there is currently no Canadian jurisprudence in respect of CBM entitlement on split-title private lands. Where compressed natural gas (CNG) and coal are separately held, and CBM ownership is not specifically addressed in the mineral severance, there is no Canadian law respecting CBM ownership. Resolution of ownership issues has proceeded on a case by case basis. Coal owners argue that there is a distinct interrelationship between CBM and its host coal strata. Gas owners argue that the chemical composition of CBM is identical to CNG, and that the recovery method is similar to that of CNG. Courts have historically applied the vernacular test to resolve mineral substance ownership disputes, which considers the meanings of the word coal and coalbed methane as defined by industry.

    Shape-morphing systems can be found in many areas, including smart textiles, autonomous robotics, biomedical devices, drug delivery and tissue engineering. The natural analogues of such systems are exemplified by nastic plant motions, where a variety of organs such as tendrils, bracts, leaves and flowers respond to environmental stimuli (such as humidity, light or touch) by varying internal turgor, which leads to dynamic conformations governed by the tissue composition and microstructural anisotropy of cell walls. Inspired by these botanical systems, we printed composite hydrogel architectures that are encoded with localized, anisotropic swelling behaviour controlled by the alignment of cellulose fibrils along prescribed four-dimensional printing pathways. When combined with a minimal theoretical framework that allows us to solve the inverse problem of designing the alignment patterns for prescribed target shapes, we can programmably fabricate plant-inspired architectures that change shape on immersion in water, yielding complex three-dimensional morphologies.

    Full Text Available Objective – To apply the principles of evidence‐based librarianship to the decisionmaking process regarding the cancellation of print serials.Design – Quantitative analysis of local and national data from various sources.Subjects – Data sources included 1249 current unbound print journals, 3465 Medline‐indexed electronic journals, statistics from the Association of Research Libraries and American Association of Health Sciences Libraries, as well as traditional library statistics.Setting – The study was conducted in the Yale University’s Cushing/Whitney Medical Library located in New Haven, Connecticut U.S.A.Methods – Several sources were targeted for data. A three‐month periodical usage study of the current issues of the library’s 1249 actively received print titles was undertaken. Excel‐generated alphabetical listings of titles were used by shelvers to indicate, with a check mark, which issues were shelved during a specified week. The workflow was adjusted to ensure only items under study were counted. Signs asking patrons not to re‐shelve journal issues were posted. Usage data were collected weekly and entered into an Excel spreadsheet where the total use of the journals was tracked. In‐house circulation, photocopy, and gate count statistics were also used. In addition to the survey, SFX statistics for the library’s electronic journals indexed in MEDLINE(3465 were gathered during the same 3 month period covered by the print usage survey. MEDLINE was chosen as the delineating factor to ensure consistent subject coverage with the print journal collection. For perspective and trends, statistics from the Association of Research Libraries and the American Association of Health Sciences Libraries were considered.Main Results – Based on the study’s findings, 53% of the print collection (657 titles received no use during the study period; 7.1 % (89 titles were used more than once per month; and 1.28% were used one or

    Mechanically flexible arrays of alkaline electrochemical cells fabricated using stencil printing onto fibrous substrates are shown to provide the necessary performance characteristics for driving ink-jet printed circuits. Due to the dimensions and material set currently required for reliable low-temperature print processing of electronic devices, a battery potential greater than that sourced by single cells is typically needed. The developed battery is a series interconnected array of 10 low resistance Zn-MnO2 alkaline cells, giving an open circuit potential of 14 V. This flexible battery is used to power an ink-jet printed 5-stage complementary ring oscillator based on organic semiconductors.

    2014-11-18

    Highly scaled direct gravure is a promising printing technique for printed electronics due to its large throughput, high resolution, and simplicity. Gravure can print features in the single micron range at printing speeds of ∼1 m/s by using an optimized cell geometry and optimized printing conditions. The filling of the cells on the gravure cylinder is a critical process, since the amount of ink in the cells strongly impacts printed feature size and quality. Therefore, an understanding of cell filling is crucial to make highly scaled gravure printed electronics viable. In this work we report a novel experimental setup to investigate the filling process in real time, coupled with numerical simulations to gain insight into the experimental observations. By varying viscosity and filling speed, we ensure that the dimensionless capillary number is a good indicator of filling regime in real gravure printing. In addition, we also examine the effect of cell size on filling as this is important for increasing printing resolution. In the light of experimental and simulation results, we are able to rationalize the dominant failure in the filling process, i.e., air entrapment, which is caused by contact line pinning and interface deformation over the cell opening.

  6. Recent trends in print portals and Web2Print applications

    Tuijn, Chris

    2009-01-01

    For quite some time now, the printing business has been under heavy pressure because of overcapacity, dropping prices and the delocalization of the production to low income countries. To survive in this competitive world, printers have to invest in tools that, on one hand, reduce the production costs and, on the other hand, create additional value for their customers (print buyers). The creation of customer portals on top of prepress production systems allowing print buyers to upload their content, approve the uploaded pages based on soft proofs (rendered by the underlying production system) and further follow-up the generation of the printed material, has been illustrative in this respect. These developments resulted in both automation for the printer and added value for the print buyer. Many traditional customer portals assume that the printed products have been identified before they are presented to the print buyer in the portal environment. The products are, in this case, typically entered by the printing organization in a so-called MISi system after the official purchase order has been received from the print buyer. Afterwards, the MIS system then submits the product to the customer portal. Some portals, however, also support the initiation of printed products by the print buyer directly. This workflow creates additional flexibility but also makes things much more complex. We here have to distinguish between special products that are defined ad-hoc by the print buyer and standardized products that are typically selected out of catalogs. Special products are most of the time defined once and the level of detail required in terms of production parameters is quite high. Systems that support such products typically have a built-in estimation module, or, at least, a direct connection to an MIS system that calculates the prices and adds a specific mark-up to calculate a quote. Often, the markup is added by an account manager on a customer by customer basis; in this

The development of digital printing using lightfast colors now rivals traditional techniques such as wood cut, screen print, lithography, etching etc. Today, with respect to artistic legitimacy, original graphics using traditional printing techniques compete with original graphics produced by digital printing techniques on the art market. What criteria distinguish traditional printing techniques from those of digital printing in the production and acquisition of original graphics? What consequences is the serious artist faced with when deciding to implement digital print production? How does digital print change original graphic acquisition decisions?

  19. The Impact of the Acquisition of Electronic Medical Texts on the Usage of Equivalent Print Books in an Academic Medical Library

    Directory of Open Access Journals (Sweden)

    Pamela S. Morgan

    2010-09-01

    Full Text Available Objectives – This study examines whether acquiring a text in electronic format effects the usage of the print version of the text, focusing specifically on medical texts. Studies in the literature dealt specifically with general collections and it was not clear if they were applicable to medical collections. It was also not clear if these studies should play a role in determining whether a medical library should purchase electronic texts or whether reserve collections are still needed for print texts.Methods – Four usage studies were conducted using data from the circulation system and the electronic vendor systems. These were 1 trends of print usage; 2 trends of electronic usage; 3 a comparison of electronic usage with print usage of the same title in the reserve collection; 4 a comparison of electronic usage with print usage of the same title in the general collection.Results – In comparison to print, substantial usage is being made of electronic books. Print is maintaining a level pattern of usage while electronic usage is increasing steadily. There was a noticeable difference in the usage levels of the electronic texts as regards to the package in which they are contained. Usage of print texts both on reserve and in the general collection has decreased over time, however the acquisition of the electronic version of a medical title had little impact on the usage of the equivalent print version. Conclusion – There is a demand for medical texts in medical libraries. Electronic versions can replace print versions of texts in reserve. Further investigation is needed of current patterns of print collection usage, with particular emphasis on trends in reserve collection usage.

    This study examines differences in the types of titles for articles that show high altmetric activity (highly alted articles) versus highly cited articles. This work expands on previous research on document titles in combination with a grounded theory approach to develop a codebook in which articles were manually coded based on 11 characteristics. The results show that there are differences and similarities in titles across many of the examined characteristics; highly cited titles and highly mentioned titles on Wikipedia have some similar characteristics such as they have the the highest percentage of substantive words; in addition, there are no or very few titles referencing outside or with humor/lightness on both platforms. Twitter and Facebook also showed some similarities having the highest percentage of humorous/light titles and lowest percentage of substantive words in their titles. (Author)

    Banding is a well-known artifact produced by printing systems. It usually appears as lines perpendicular to the process direction of the print. Therefore, banding is an important print quality issue which has been analyzed and assessed by many researchers. However, little literature has focused on the study of the masking effect of content for this kind of print quality issue. Compared with other image and print quality research, our work is focused on the print quality of typical documents printed on a digital commercial printing press. In this paper, we propose a Masking Mediated Print Defect Visibility Predictor (MMPDVP) to predict the visibility of defects in the presence of customer content. The parameters of the algorithm are trained from ground-truth images that have been marked by subjects. The MMPDVP could help the press operator decide whether the print quality is acceptable for specific customer requirements. Ultimately, this model can be used to optimize the print-shop workflow.

    2012-06-01

    In this paper, a novel design concept for roll-to-roll printing equipment used for manufacturing printed electronic devices by multi-layer printing is presented. The roll-to-roll printing system mainly consists of printing units for patterning the circuits, tension control components such as feeders, dancers, load cells, register measurement and control units, and the drying units. It has three printing units which allow switching among the gravure, gravure-offset, and flexo printing methods by changing the web path and the placements of the cylinders. Therefore, depending on the application devices and the corresponding inks used, each printing unit can be easily adjusted to the required printing method. The appropriate printing method can be chosen depending on the desired printing properties such as thickness, roughness, and printing quality. To provide an example of the application of the designed printing equipment, we present the results of printing tests showing the variations in the printing properties of the ink for different printing methods.

    2013-01-01

    Dexterous robotic hands are changing the way robots and humans interact and use common tools. Unfortunately, the complexity of the joints and actuations drive up the manufacturing cost. Some cutting edge and commercially available rapid prototyping machines now have the ability to print multiple materials and even combine these materials in the same job. A 3D model of a robotic hand was designed using Creo Parametric 2.0. Combining "hard" and "soft" materials, the model was printed on the Object Connex350 3D printer with the purpose of resembling as much as possible the human appearance and mobility of a real hand while needing no assembly. After printing the prototype, strings where installed as actuators to test mobility. Based on printing materials, the manufacturing cost of the hand was $167, significantly lower than other robotic hands without the actuators since they have more complex assembly processes.

  1. Data-driven deselection for monographs: a rules-based approach to weeding, storage, and shared print decisions

    Directory of Open Access Journals (Sweden)

    Rick Lugg

    2012-07-01

    Full Text Available The value of local print book collections is changing. Even as stacks fill and library traffic grows, circulation continues to decline. Across the ‘collective collection’, millions of unused books occupy prime central campus space. Meanwhile, users want more collaborative study space and online resources. Libraries want room for information commons, teaching and learning centers and cafes. Done properly, removing unused books can free space for these and other purposes, with little impact on users. Many low-use titles are securely archived, accessible digitally, and widely held in print. Surplus copies can be removed without endangering the scholarly record. But identifying candidates for deselection is time-consuming. Batch-oriented tools that incorporate both archival and service values are needed. This article describes the characteristics of a decision-support system that assembles deselection metadata and enables library-defined rules to generate lists of titles eligible for withdrawal, storage, or inclusion in shared print programs.

    2011-10-01

    The extent of noise in five printing companies in Novi Sad, Serbia, was determined using TES-1358A Sound Analyzer with RS-232 Interface. The data on equivalent A-level (dBA), as well as, maximum and minimum sound pressure levels were collected. It was found that folders and offset printing units are the predominant noise sources, with the average L (eq) levels of 87.66 and 82.7 dBA, respectively. Forty percent of the machines produced noise levels above the limiting threshold level of 85 dBA, allowed by law. The noise in all printing companies was dominated by higher frequency noise, and the maximum level mostly appeared at 4,000 Hz. For offset printing machines and folders, the means of L (eq) levels exceeded the permissible levels given by NR-80 curve at higher frequencies. There are no published studies of occupational noise and hearing impairment of workers exposed to hazardous noise in printing industry in Serbia. More extensive studies are needed to determine the exact impact of noise on the workers. Technical and organizational measures in order to control noise and prevent noise exposure, and general hearing conservation program to protect workers, should be introduced in printing industry.

    2008-01-01

    Organ printing or biomedical application of rapid prototyping, also defined as additive layer-by-layer biomanufacturing, is an emerging transforming technology that has potential for surpassing traditional solid scaffold-based tissue engineering. Organ printing has certain advantages: it is an automated approach that offers a pathway for scalable reproducible mass production of tissue engineered products; it allows a precised simultaneous 3D positioning of several cell types; it enables creation tissue with a high level of cell density; it can solve the problem of vascularization in thick tissue constructs; finally, organ printing can be done in situ. The ultimate goal of organ-printing technology is to fabricate 3D vascularized functional living human organs suitable for clinical implantation. The main practical outcomes of organ-printing technology are industrial scalable robotic biofabrication of complex human tissues and organs, automated tissue-based in vitro assays for clinical diagnostics, drug discovery and drug toxicity, and complex in vitro models of human diseases. This article describes conceptual framework and recent developments in organ-printing technology, outlines main technological barriers and challenges, and presents potential future practical applications.

    This work demonstrates mass production of printable multi-color lasing microarrays based on uniform hemispherical microcavities on a distributed Bragg reflector using inkjet technique. By embedding two different organic dyes into these prints, optically pumped whispering gallery mode microlasers with lasing wavelengths in green and red spectral ranges are realized. The spectral linewidth of the lasing modes is found as narrow as 0.11 nm. Interestingly, dual-color lasing emission in the ranges of 515-535 nm and 585-605 nm is simultaneously achieved by using two different dyes with certain ratios. Spectroscopic measurements elucidate the energy transfer process from the green dye (donor) to the red one (acceptor) with an energy transfer efficiency up to 80% in which the nonradiative Förster resonance energy transfer dominates. As such, the acceptor lasing in the presence of donor exhibits a significantly lower (˜2.5-fold) threshold compared with that of the pure acceptor lasing with the same concentration.

  13. WikiPrints: rendering enterprise Wiki content for printing

    Science.gov (United States)

    Berkner, Kathrin

    2010-02-01

    Wikis have become a tool of choice for collaborative, informative communication. In contrast to the immense Wikipedia, that serves as a reference web site and typically covers only one topic per web page, enterprise wikis are often used as project management tools and contain several closely related pages authored by members of one project. In that scenario it is useful to print closely related content for review or teaching purposes. In this paper we propose a novel technique for rendering enterprise wiki content for printing called WikiPrints, that creates a linearized version of wiki content formatted as a mixture between web layout and conventional document layout suitable for printing. Compared to existing print options for wiki content, Wikiprints automatically selects content from different wiki pages given user preferences and usage scenarios. Meta data such as content authors or time of content editing are considered. A preview of the linearized content is shown to the user and an interface for making manual formatting changes provided.

    The ability to three-dimensionally interweave biological and functional materials could enable the creation of bionic devices possessing unique and compelling geometries, properties, and functionalities. Indeed, interfacing high performance active devices with biology could impact a variety of fields, including regenerative bioelectronic medicines, smart prosthetics, medical robotics, and human-machine interfaces. Biology, from the molecular scale of DNA and proteins, to the macroscopic scale of tissues and organs, is three-dimensional, often soft and stretchable, and temperature sensitive. This renders most biological platforms incompatible with the fabrication and materials processing methods that have been developed and optimized for functional electronics, which are typically planar, rigid and brittle. A number of strategies have been developed to overcome these dichotomies. One particularly novel approach is the use of extrusion-based multi-material 3D printing, which is an additive manufacturing technology that offers a freeform fabrication strategy. This approach addresses the dichotomies presented above by (1) using 3D printing and imaging for customized, hierarchical, and interwoven device architectures; (2) employing nanotechnology as an enabling route for introducing high performance materials, with the potential for exhibiting properties not found in the bulk; and (3) 3D printing a range of soft and nanoscale materials to enable the integration of a diverse palette of high quality functional nanomaterials with biology. Further, 3D printing is a multi-scale platform, allowing for the incorporation of functional nanoscale inks, the printing of microscale features, and ultimately the creation of macroscale devices.

    2011-07-01

    Full Text Available Electronic books (e-books are gaining popularity for personal reading. Options for access to a large selection of book titles and “anytime/anywhere” reading choices have added to the increased use of e-books. For this study, 22 third-grade students completed satisfaction surveys and reading comprehension tests on three separate reading sessions: one traditional print-based and two e-book titles. Indicators of reading engagement included motivation for independent reading and comprehension as measured by standardized tests on the print book and both e-books. Results showed that format was not as important as students’ identification with setting, characters, and theme of the book. Students did, however, indicate a preference for e-books when given the option of a wide selection of titles and the freedom to choose their own e-book. Students further indicated a preference for the amenities associated with e-book reading such as pop-up definitions and pronunciations of words, automatic page turning, and the option of read-aloud narration. The authors concluded that children quickly become comfortable with e-books and welcomed the technology. However, they are not completely ready to disregard print books.

    Full Text Available Meeting the demand for faster turnrounds and shorter print runs goes beyond making the printing press easier to set up and change. There is little point in producing plates and then sheets from a press if the post press area does not change to keep abreast of developments in prepress and the print room. The greatest impact is going to come from JDF, the end to end production data format which is finding wide spread acceptance in print areas. To date finishing equipment manufacturers are not as well represented within the CIP4 organisation as prepress and press vendors, but the major manufacturers are members. All are working to the goal of complete connectivity.The idea of JDF is that if the format of a print product like a magazine is known during the creation phases, the information can be used to preset machinery that is going to be used to produce it, so avoiding input errors and saving manufacturing time.A second aspect to JDF is that information about performance and progress is gathered and can be retrieved from a central point or made available to a customer. Production scheduling and costing becomes more accurate and customer relationships are deepened. However JDF to its fullest extent is not yet in use in connecting the finishing area to the rest of the printing plant. Around the world different companies are testing the idea of JDF to connect saddle stitchers, guillotines and binders with frantic work underway to be able to show results soon.

    2016-08-11

    All-printed paper-based substrate memory devices are described. In an embodiment, a paper-based memory device is prepared by coating one or more areas of a paper substrate with a conductor material such as a carbon paste, to form a first electrode of a memory, depositing a layer of insulator material, such as titanium dioxide, over one or more areas of the conductor material, and depositing a layer of metal over one or more areas of the insulator material to form a second electrode of the memory. In an embodiment, the device can further include diodes printed between the insulator material and the second electrode, and the first electrode and the second electrodes can be formed as a crossbar structure to provide a WORM memory. The various layers and the diodes can be printed onto the paper substrate by, for example, an ink jet printer.

    Printed Electronics is a rapidly developing sector in the electronics industry, in which nanostructured materials are playing an increasingly important role. In particular, inks containing dispersions of semiconducting nanoparticles, can form nanocomposite materials with unique electronic properties when cured. In this study we have extended on our previous studies of functional nanoparticle electronic inks, with the development of a solvent-based silicon ink for printed electronics which is compatible with existing silver inks, and with the investigation of other metal nanoparticle based inks. It is shown that both solvent-based and water-based inks can be used for both silver conductors and semiconducting silicon, and that qualitatively there is no difference in the electronic properties of the materials printed with a soluble polymer binder to when an acrylic binder is used.

  17. Image analysis of Renaissance copperplate prints

    Science.gov (United States)

    Hedges, S. Blair

    2008-02-01

    From the fifteenth to the nineteenth centuries, prints were a common form of visual communication, analogous to photographs. Copperplate prints have many finely engraved black lines which were used to create the illusion of continuous tone. Line densities generally are 100-2000 lines per square centimeter and a print can contain more than a million total engraved lines 20-300 micrometers in width. Because hundreds to thousands of prints were made from a single copperplate over decades, variation among prints can have historical value. The largest variation is plate-related, which is the thinning of lines over successive editions as a result of plate polishing to remove time-accumulated corrosion. Thinning can be quantified with image analysis and used to date undated prints and books containing prints. Print-related variation, such as over-inking of the print, is a smaller but significant source. Image-related variation can introduce bias if images were differentially illuminated or not in focus, but improved imaging technology can limit this variation. The Print Index, the percentage of an area composed of lines, is proposed as a primary measure of variation. Statistical methods also are proposed for comparing and identifying prints in the context of a print database.

    Conventional electronic document filing systems are inconvenient because the user must specify the keywords in each document for later searches. To solve this problem, automatic keyword extraction methods using natural language processing and character recognition have been developed. However, these methods are slow, especially for japanese documents. To develop a practical electronic document filing system, we focused on the extraction of keyword areas from a document by image processing. Our fast title extraction method can automatically extract titles as keywords from business documents. All character strings are evaluated for similarity by rating points associated with title similarity. We classified these points as four items: character sitting size, position of character strings, relative position among character strings, and string attribution. Finally, the character string that has the highest rating is selected as the title area. The character recognition process is carried out on the selected area. It is fast because this process must recognize a small number of patterns in the restricted area only, and not throughout the entire document. The mean performance of this method is an accuracy of about 91 percent and a 1.8 sec. processing time for an examination of 100 Japanese business documents.

    We report the memory device on paper by means of an all-printing approach. Using a sequence of inkjet and screen-printing techniques, a simple metal-insulator-metal device structure is fabricated on paper as a resistive random access memory with a potential to reach gigabyte capacities on an A4 paper. The printed-paper-based memory devices (PPMDs) exhibit reproducible switching endurance, reliable retention, tunable memory window, and the capability to operate under extreme bending conditions. In addition, the PBMD can be labeled on electronics or living objects for multifunctional, wearable, on-skin, and biocompatible applications. The disposability and the high-security data storage of the paper-based memory are also demonstrated to show the ease of data handling, which are not achievable for regular silicon-based electronic devices. We envision that the PPMDs manufactured by this cost-effective and time-efficient all-printing approach would be a key electronic component to fully activate a paper-based circuit and can be directly implemented in medical biosensors, multifunctional devices, and self-powered systems. © 2014 American Chemical Society.

    In inkless microcontact printing (IμCP) by soft lithography, the poly(dimethylsiloxane) (PDMS) stamp transfers uncured polymer to a substrate corresponding to its pattern. The spontaneous diffusion of PDMS oligomers to the surface of the stamp that gives rise to this deleterious side effect has been leveraged to fabricate a variety of devices, such as organic thin film transistors, single-electron devices, and biomolecular chips. Here we report an anomalous observation on a partially cured PDMS stamp where the transfer of oligomers onto Au occurred on regions that were not in contact with the stamp, while the surface in contact with the stamp was pristine with no polymer. On the SiO2 surface of the same chip, as expected, the transfer of PDMS occurred exclusively on regions in contact with the stamp. The printing on Au was quantified by a novel method where the submonolayer of PDMS transfer was measured by probing the local electrochemical passivation of the Au. The local transfer of polymer on SiO2 (and also Au) was measured by selective deposition of Au nanoparticle necklaces that exclusively deposited on PDMS at submonolayer sensitivity. It was discovered that the selectivity and sharpness of PDMS deposition on Au for inkless printing (i.e., negative) is significantly better than the traditional (positive) microcontact printing where the stamp is "inked" with low molecular weight PDMS.

    In the past few decades, 3D printing has played a significant role in fabricating scaffolds with consistent, complex structure that meet patient-specific needs in future clinical applications. Although many studies have contributed to this emerging field of additive manufacturing, which includes material development and computer-aided scaffold design, current quantitative analyses do not correlate material properties, printing parameters, and printing outcomes to a great extent. A model that correlates these properties has tremendous potential to standardize 3D printing for tissue engineering and biomaterial science. In this study, we printed poly(lactic-co-glycolic acid) (PLGA) utilizing a direct melt extrusion technique without additional ingredients. We investigated PLGA with various lactic acid:glycolic acid (LA:GA) molecular weight ratios and end caps to demonstrate the dependence of the extrusion process on the polymer composition. Micro-computed tomography was then used to evaluate printed scaffolds containing different LA:GA ratios, composed of different fiber patterns, and processed under different printing conditions. We built a statistical model to reveal the correlation and predominant factors that determine printing precision. Our model showed a strong linear relationship between the actual and predicted precision under different combinations of printing conditions and material compositions. This quantitative examination establishes a significant foreground to 3D print biomaterials following a systematic fabrication procedure. Additionally, our proposed statistical models can be applied to couple specific biomaterials and 3D printing applications for patient implants with particular requirements.

    Electrochemical biosensors show great promise for point-of-care applications due to their low cost, portability and compatibility with microfluidics. The miniature size of these sensors provides advantages in terms of sensitivity, specificity and allows them to be mass produced in arrays. The most reliable fabrication technique for these sensors is lithography followed by metal deposition using sputtering or chemical vapor deposition techniques. This technique which is usually done in the cleanroom requires expensive masking followed by deposition. Recently, cheaper printing techniques such as screen-printing and ink-jet printing have become popular due to its low cost, ease of fabrication and mask-less method. In this paper, two different printing techniques namely inkjet and screen printing are demonstrated for an electrochemical biosensor. For ink-jet printing technique, optimization of key printing parameters, such as pulse voltages, drop spacing and waveform setting, in-house temperature and cure annealing for obtaining the high quality droplets, are discussed. These factors are compared with screen-printing parameters such as mesh size, emulsion thickness, minimum spacing of lines and curing times. The reliability and reproducibility of the sensors are evaluated using scotch tape test, resistivity and profile-meter measurements. It was found that inkjet printing is superior because it is mask-less, has minimum resolution of 100 µm compared to 200 µm for screen printing and higher reproducibility rate of 90% compared to 78% for screen printing.

This novel technique allows developing printed antennas with interesting features such as multifrequency (simultaneous operation over two or more frequency bands and multifunctionality (e. g. radiation pattern diversity. Moreover, compactness is also achieved and the main advantages of conventional printed antennas (light weight, low profile, low cost ... are maintained. Different types of metamaterial-loaded printed antennas are reviewed: printed dipoles and patch antennas. Several prototypes are designed, manufactured and measured showing good results. Furthermore, simple but accurate equivalent models are proposed. These models allow an easy and quick design of metamaterial-loaded printed antennas. Finally, two interesting applications based on the proposed antennas are reviewed: the patch antennas are used as radiating elements of emerging active RFID systems in the microwave band and the metamaterial-loaded printed dipoles are employed to increase the performance of log-periodic arrays.

    For whatever kind of literary forms, the first thing that we come into contact with is the title. The title functions as not only the eye catcher but also the summary of the context. Any legal document starts with its title and a good translation of the ti-tle lays the foundation for the interpretation of follow-up terms and conditions. However, translating titles of laws is affected by different factors, especially cultural differences, such as history, diction and conventions. Anyway, cultural impact on translation of law titles can be handled tactfully.

    Full Text Available Background: Lip prints and fingerprints are considered to be unique to each individual. The study of fingerprints and lip prints is very popular in personal identification of the deceased and in criminal investigations. Aims: This study was done to find the predominant lip and fingerprint patterns in males and females in the North Indian population and also to find any correlation between lip print and fingerprint patterns within a gender. Materials and Methods: Two hundred students (100 males, 100 females were included in the study. Lip prints were recorded for each individual using a dark-colored lipstick and the right thumb impression was recorded using an ink pad. The lip prints and fingerprints were analyzed using a magnifying glass. The Chi-square test was used for statistical analysis. Results: The branched pattern in males and the vertical pattern in females were the predominant lip print patterns. The predominant fingerprint pattern in both males and females was found to be the loop pattern, followed by the whorl pattern and then the arch pattern. No statistically significant correlation was found between lip prints and fingeprints. However, the arch type of fingerprint was found to be associated with different lip print patterns in males and females. Conclusion: Lip prints and fingerprints can be used for personal identification in a forensic scenario. Further correlative studies between lip prints and fingerprints could be useful in forensic science for gender identification.

    The feasibility of thermal ink jet printing as a robust process for biosurface engineering was demonstrated. The strategy investigated was to reconstruct a commercial printer and take advantage of its colour management interface. High printing resolution was achieved by formulating bio-inks of viscosity and surface tension similar to those of commercial inks. Protein and enzyme denaturation during thermal ink jet printing was shown to be insignificant. This is because the time spent by the biomolecules in the heating zone of the printer is negligible; in addition, the air and substrate of high heat capacity absorb any residual heat from the droplet. Gradients of trophic/tropic factors can serve as driving force for cell growth or migration for tissue regeneration. Concentration gradients of proteins were printed on scaffolds to show the capability of ink jet printing. The printed proteins did not desorb upon prolonged immersion in aqueous solutions, thus allowing printed scaffold to be used under in vitro and in vivo conditions. Our group portrait was ink jet printed with a protein on paper, illustrating that complex biopatterns can be printed on large area. Finally, patterns of enzymes were ink jet printed within the detection and reaction zones of a paper diagnostic.

    Film-based photovoltaic modules employ monolithic interconnects to minimize resistance loss and enhance module voltage via series connection. Conventional interconnect construction occurs sequentially, with a scribing step following deposition of the bottom electrode, a second scribe after deposition of absorber and intermediate layers, and a third following deposition of the top electrode. This method produces interconnect widths of about 300 um, and the area comprised by interconnects within a module (generally about 3%) does not contribute to power generation. The present work reports on an increasingly popular strategy capable of reducing the interconnect width to less than 100 um: printing interconnects. Cost modeling projects a savings of about $0.02/watt for CdTe module production through the use of printed interconnects, with savings coming from both reduced capital expense and increased module power output. Printed interconnect demonstrations with copper-indium-gallium-diselenide and cadmium-telluride solar cells show successful voltage addition and miniaturization down to 250 um. Material selection guidelines and considerations for commercialization are discussed.

    The ability to three-dimensionally interweave biological tissue with functional electronics could enable the creation of bionic organs possessing enhanced functionalities over their human counterparts. Conventional electronic devices are inherently two-dimensional, preventing seamless multidimensional integration with synthetic biology, as the processes and materials are very different. Here, we present a novel strategy for overcoming these difficulties via additive manufacturing of biological cells with structural and nanoparticle derived electronic elements. As a proof of concept, we generated a bionic ear via 3D printing of a cell-seeded hydrogel matrix in the precise anatomic geometry of a human ear, along with an intertwined conducting polymer consisting of infused silver nanoparticles. This allowed for in vitro culturing of cartilage tissue around an inductive coil antenna in the ear, which subsequently enables readout of inductively-coupled signals from cochlea-shaped electrodes. The printed ear exhibits enhanced auditory sensing for radio frequency reception, and complementary left and right ears can listen to stereo audio music. Overall, our approach suggests a means to intricately merge biologic and nanoelectronic functionalities via 3D printing. PMID:23635097

    Full Text Available Flexography is a printing technique widely used in the packaging production. The main feature of the flexography is the usage of the printing plate which is elastically deformed during the reproduction process. The printing plate is made of elastic material, rubber or nowadays mainly of different types of photopolymer. Elasticity of the plate enables printing on a wide range of printing substrates (papers, foils, board, magazines, hygienic papers etc., which is one of its advantages compared to other printing techniques. On the other hand, deformations of the printing plate in the printing process caused by the pressure between the printing plate and substrate present major limitation of the flexography. Beside functional properties of the printing plate in the printing process, the plate making process including photopolymerization highly influences the value of the halftones on the printing plate, and consequently on the final product.  The aim of this paper is to examine the influence of the screen ruling on the formation of the printing elements and the procedure of the printing plate making process adjustment in order to achieve optimal quality of the printing plate and, therefore, the final product. Results have shown that the usage of different screen ruling is of great significance in processes of printing plate curve adjustment. It was proven that the usage of different screen ruling highly influences the relief depth and a cross-section of the printing elements (3D analysis, which have a significant impact on the final product quality, but cannot be detected in 2D analysis.

Beside functional properties of the printing plate in the printing process, the plate making process including photopolymerization highly influences the value of the halftones on the printing plate, and consequently on the final product. The aim of this paper is to examine the influence of the screen ruling on the formation of the printing elements and the procedure of the printing plate making process adjustment in order to achieve optimal quality of the printing plate and, therefore, the final product.Results have shown that the usage of different screen ruling is of great significance in processes of printing plate curve adjustment. It was proven that the usage of different screen ruling highly influences the relief depth and a cross-section of the printing elements (3D analysis, which have a significant impact on the final product quality, but cannot be detected in 2D analysis.

  20. New Approaches for Printed Electronics Manufacturing

    Science.gov (United States)

    Mahajan, Ankit

    In printed electronics, electronic inks are patterned onto flexible substrates using roll-to-roll (R2R) compatible graphic printing methods. For applications where large-area, conformal electronics are necessary, printed electronics holds a competitive advantage over rigid, semiconductor circuitry, which does not scale efficiently to large areas. However, in order to fully realize the true potential of printed electronics, several manufacturing hurdles need to be overcome. Firstly, minimum feature sizes produced by graphic printing methods are typically greater than 25 microm, which is at least an order of magnitude higher for dense, high performing electronics. In this thesis, conductive features down to 1.5 microm are demonstrated using a novel inkjet printing-based process. Secondly, high-resolution printed conductors usually have poor current-carrying capacity, especially for longer wires in large-area applications. This thesis explores the fundamentals of aerosol-jet printing and reveals the regime for printing high-resolution lines with excellent current carrying capacity. Additionally, a novel manufacturing process is demonstrated, which can process 2.5 microm wide conductive wires with linear resistances as small as 5 O mm -1. Another challenge for printed electronics manufacturing is to deal with topography produced on the substrate surface by printed features. Besides complicating the subsequent use of contact-printing methods, surface topography is a source of poor device yields as well. This thesis describes two novel methodologies of creating topography-free printed surfaces. In the first method, nanometer-level smooth, planarized silver lines are obtained using a transfer printing approach. In the second method, open microchannels, imprinted in plastic substrates, are filled with a controlled amount of metal using liquid-based additive processes, to obtain conductive wires flush with the substrate surface. Finally, this thesis addresses the issue of

    When translating the titles of films, translators are faced with not only different meanings of Chinese and English lan-guage, but also various cultural connotations behind the titles. Therefore, translators should take cultural differences into account in order to make the translated titles close to the connotations of the source culture. Such cultural differences as religious dissimi-larities, historical allusions and idiomatic expressions (or idioms) are major concerns when translating film titles.

    2012-04-01

    In recent years, printed electronics have received attention as a method to produce low-cost macro electronics on flexible substrates. In this regard, inkjet and aerosol printing have been the primary printing methods for producing passive electrical components, transistors, and a number of sensors. In this research, a custom aerosol printer was utilized to create a strain sensor capable of measuring static and dynamic strain. The proposed sensor was created by aerosol printing a multiwall carbon nanotube solution onto an aluminum beam covered with an insulating layer. After printing the carbon nanotube-based sensor, the sensor was tested under quasi-static and vibration strain conditions, and the results are presented. The results show that the printed sensor could potentially serve as an effective method for measuring dynamic strain of structural components.

    Recent interest in flexible electronics and wearable devices has created a demand for fast and highly repeatable printing processes suitable for device manufacturing. Robust printing technology is critical for the integration of sensors and other devices on flexible substrates such as paper and textile. An atmospheric pressure plasma-based printing process has been developed to deposit different types of nanomaterials on flexible substrates. Multiwalled carbon nanotubes were deposited on paper to demonstrate site-selective deposition as well as direct printing without any type of patterning. Plasma-printed nanotubes were compared with non-plasma-printed samples under similar gas flow and other experimental conditions and found to be denser with higher conductivity. The utility of the nanotubes on the paper substrate as a biosensor and chemical sensor was demonstrated by the detection of dopamine, a neurotransmitter, and ammonia, respectively.

    To reduce and in many cases eliminate the costs associated with high volume printing of consumer and industrial products, this paper investigates and validates the use of the new generation of high speed pulse on demand (POD) lasers in concert with high speed (HS) polygon scan heads (PSH). Associated costs include consumables such as printing ink and nozzles, provisioning labor, maintenance and repair expense as well as reduction of printing lines due to high through put. Targets that are applicable and investigated include direct printing on plastics, printing on paper/cardboard as well as printing on labels. Market segments would include consumer products (CPG), medical and pharmaceutical products, universal ID (UID), and industrial products. In regards to the POD lasers employed, the wavelengths include UV(355nm), Green (532nm) and IR (1064nm) operating within the repetition range of 180 to 250 KHz.

    Full Text Available This paper presents environmental data relating to gravure and offset printing. It focuses on the printing steps in the production chain of publication printed products. The other steps in the life-cycle of printed products have also been studied but they are not the subjects of this paper.The study is based on case studies, where almost twenty gravure printers and ten offset printers from around Europe and the United States have been involved.The general, significant environmental aspects of publication printed products have been identified as the following; use of paper, use of energy, consumption (loss of volatile organic compounds (VOC, including toluene, hazardous waste and environmental management. Transport has also been identified as a significant environmental aspect for printed products but, to a great extent, its magnitude depends on the particular product. The data collected from printers in different parts of the world were compared to environmental data provided by offset printers in Sweden, which were mainly taken from coldset printers.This paper presents significant environmental data for a fairly large number of companies representing a considerable part of the printing capacity, not only in Europe but also worldwide. These data can provide guidance for both printers and buyers of printed products working to achieve continualimprovements and striving towards more environmentally adapted printed products. To some extent, the data can also be used as reference values, since there are few compilations of data providing a general coverage of printers in different parts of the world.

  1. Active origami by 4D printing

    2014-09-01

    Recent advances in three dimensional (3D) printing technology that allow multiple materials to be printed within each layer enable the creation of materials and components with precisely controlled heterogeneous microstructures. In addition, active materials, such as shape memory polymers, can be printed to create an active microstructure within a solid. These active materials can subsequently be activated in a controlled manner to change the shape or configuration of the solid in response to an environmental stimulus. This has been termed 4D printing, with the 4th dimension being the time-dependent shape change after the printing. In this paper, we advance the 4D printing concept to the design and fabrication of active origami, where a flat sheet automatically folds into a complicated 3D component. Here we print active composites with shape memory polymer fibers precisely printed in an elastomeric matrix and use them as intelligent active hinges to enable origami folding patterns. We develop a theoretical model to provide guidance in selecting design parameters such as fiber dimensions, hinge length, and programming strains and temperature. Using the model, we design and fabricate several active origami components that assemble from flat polymer sheets, including a box, a pyramid, and two origami airplanes. In addition, we directly print a 3D box with active composite hinges and program it to assume a temporary flat shape that subsequently recovers to the 3D box shape on demand.

  2. Banner Pages on the New Printing Infrastructure

    2006-01-01

    Changes to the printing service were announced in CERN Bulletin No. 37-38/2006. In the new infrastructure, the printing of the banner page has been disabled in order to reduce paper consumption. Statistics show that the average print job size is small and the paper savings by not printing the banner page could be up to 20 %. When each printer is moved onto the new infrastructure banner page printing will be disabled. In the case of corridor printers which are shared by several users, the Helpdesk can re-enable banner page printing upon request. We hope ultimately to arrive at a situation where banner page printing is enabled on fewer than 10% of printers registered on the network. You can still print banner pages on printers where it has been centrally disabled by using Linux. Simply add it to your print job on the client side by adding the -o job-sheets option to your lpr command.

    The space environment requires robust sensing, control, and automation, whether in support of human spaceflight or of robotic exploration. Spaceflight embodies the known extremes of temperature, radiation, shock, vibration, and static loads, and demands high reliability at the lowest possible mass. Because printed electronic circuits fulfill all these requirements, printed circuit technology and the exploration of space have been closely coupled throughout their short histories. In this presentation, we will explore the space (and space launch) environments as drivers of printed circuit design, a brief history of NASA's use of printed electronic circuits, and we will examine future requirements for such circuits in our continued exploration of space.

The purpose of a comprehensive content analysis of print advertising is to determine whether the items indicated by evolutionists such as animals, flowers, certain types of landscapes, beautiful humans, and some colors are part of real advertising strategies. This article has shown that many evolutionary hypotheses (although not all of them are supported by empirical data. Along with these hypotheses, some inferences from Bourdieu’s cultural capital theory were tested. It turned out that advertising uses both biological schemata and cultural patterns to make an image more likable.

    Mastandrea, Stefano; Umiltà, Maria A.

    2016-01-01

    Very often the titles of Futurist paintings contain words denoting movement in order to satisfy their artistic poetic focused on motion and velocity. The aim of the present study is to investigate the reported dynamism and aesthetic quality of several Futurist artworks as a function of their title. Ten Futurist artworks with a movement-related word in the title were selected for this study. The titles were manipulated, resulting in four conditions for each painting: the “original title” with the movement word; an “increased” title in which an adjective was added in order to intensify the sense of dynamism; a “decreased” title, in which the movement word was eliminated; no title. Participants evaluated the movement suggested by each painting in the four different title conditions, rated their beauty and reported how much they liked the work. Results showed that the manipulation of the title had an effect on the reported movement: compared to the others, paintings presented with the “original” and with the “increased” title received significant higher movement scores. Of interest, beauty did not differ across conditions, but liking was higher for the conditions with more movement. Lastly, positive correlations between the quantity of perceived movement and aesthetic evaluation were found. From the present results it can be concluded that Futurists attributed much relevance to the titles of their artworks in order to effectively increase the expression of the movement represented.

  9. Dramatic Advance in Quality in Flexographic Printing

    Directory of Open Access Journals (Sweden)

    Jochen Richter

    2004-12-01

    Full Text Available The enormous changes in flexography printing in recent years concerning the printing quality achievable cannot generally be ascribed to a single revolutionary invention, but are the result of continuous developments to the complete system. Thus the direct drive technology in all machine types and its associated advantages in terms of printing length corrections has become established since drupa 2000. The race for ever finer raster rolls has also been completed to the benefit of improvements in bowl geometry and in ceramic surfaces. Clearly improved colour transfer behaviour has become feasible as a result. In a closely intermeshed system such as flexography printing this naturally has to have an effect on the printing colours used. Further improvements in bonding agents and pigment concentrations now allow users to print ever thinner colour layers while maintaining all of the required authenticities.Furthermore, it has become possible to reduce additional disturbing characteristics in the UV colour area, such as the unpleasant odour. While the digital imaging of printing plates has primarily been improved in terms of economic efficiency by the use of up to eight parallel laser beams, extreme improvements in the system are noticeable especially in the area of directly engraved printing moulds. Whereas many still dismissed directly engraved polymer plates at the last drupa as a laboratory system, the first installation was recently placed on the market a mere three years later. A further noteworthy innovation of recent years that has reached market maturity is thin sleeve technology, which combines the advantages of a photopolymer plate with a round imaged printing mould. There are no high sleeve costs for each printing mould, except for one-off cost for an adapter sleeve. To conclude, it can be said that although flexography printing has experienced many new features in the time between drupa 2000 and today, it still has enormous potential for

    Full Text Available Personal identification is one of the most important requirements in all e-commerce and criminal detection applications. In this framework, a novel palm print representation method, namely orthogonal line ordinal features, is proposed. The palm print registration, feature extraction, palm print verification and palm print recognition modules are designed to manage the palm prints and the palm print database module is designed to store their palm prints and the person details in the database. The feature extraction module is proposed to extract the ordinal measurements for the palm prints. The verification module is designed to verify the palm print with the personal identification record. The recognition module is proposed to find out the relevant person associated with the palm print image. The proposed palm print recognition scheme uses the intensity and brightness to measure the ordinal measurement. The ordinal measures are estimated for the 4 x 4 regions of the palm print images.

    Digital printing brings the tremendous impacts not only to the printing industry but also to the publishing industry. Colleges could establish a "Printing and Publishing Center" to adopt the development of digital printing technology. It is necessary to build up a printing and publishing system to apply the digital printing's characteristics to fulfill the functions of college education. This system must contain the functions of digital right management (DRM), Internet, and database management system (DBMS). It could print the partial chapters of one of more particular textbooks and publish the books by using the digital printing press in order to present the most updating information. It could fully use the benefits of print-on-demand, variable-data printing, and a short-run printing of digital printing. For the system, it could satisfy the needs of teachers and students in teaching and learning in college.

    2011-03-01

    Graphene films have been synthesized on metal foils using CVD growth and have the potential to be compatible with roll-to-roll printing. To be usable in electronic devices, these films need to be removed from the metallic substrate. Currently this is accomplished by spin coating a polymer film over the graphene and chemically etching away the metal substrate. We have developed a direct printing method that allows graphene films to be printed off the metal substrate onto a polymer substrate. This printing process does not generate chemical waste, is compatible with roll-to-toll processing and renders the metal foil reusable. Adhesion of the graphene film to the polymer substrate is established by attaching perfluorophenylazides (PFPA) azide linker molecules to a plasma activated polymer surface. The transfer printing was performed by placing the PFPA treated polymer surface in contact with a graphene covered Cu foil and heating under pressure. Graphene films successfully printed onto a polystyrene substrate have been characterized by Raman spectroscopy and electrical measurements revealed the presence of Gr on the polymer surface. Details of the printing process along with characteristics of the graphene film after printing will be presented.

    2014-05-07

    In this issue we highlight emerging microfabrication approaches suitable for microfluidic systems with a focus on "additive manufacturing" processes (i.e. printing). In parallel with the now-wider availability of low cost consumer-grade 3D printers (as evidenced by at least three brands of 3D printers for sale in a recent visit to an electronics store in Akihabara, Tokyo), commercial-grade 3D printers are ramping to higher and higher resolution with new capabilities, such as printing of multiple materials of different transparency, and with different mechanical and electrical properties. We highlight new work showing that 3D printing (stereolithography approaches in particular) has now risen as a viable technology to print whole microfluidic devices. Printing on 2D surfaces such as paper is an everyday experience, and has been used widely in analytical chemistry for printing conductive materials on paper strips for glucose and other electrochemical sensors. We highlight recent work using electrodes printed on paper for digital microfluidic droplet actuation. Finally, we highlight recent work in which printing of membrane-bound droplets that interconnect through bilayer membranes may open up an entirely new approach to microfluidic manufacturing of soft devices that mimic physiological systems.

    Background: Lip prints are unique and can be used in personal identification. Very few studies are available which establish them as biological evidence in the court of law. Thus, the objective of this study was to attempt to isolate DNA and obtain full short tandem repeat (STR) loci of the individual from the lip prints on different surfaces. Materials and Methods: Twelve lip prints were procured on different surfaces such as tissue paper, cotton cloth, ceramic tile, and glass surface. Latent lip prints were developed using fingerprint black powder. Lipstick-coated lip prints were also collected on the same supporting items. DNA was isolated, quantified, and amplified using Identifiler™ kit to type 15 STR loci. Results: Ample quantity of DNA was extracted from all the lip print impressions and 15 loci were successfully located in seven samples. Fourteen loci were successfully typed in 3 lip impressions while 13 loci were typed in 2 samples. Conclusion: This study emphasizes the relevance of lip prints at the scene of crime. Extraction of DNA followed by typing of STR loci establishes the lip prints as biological evidence too. Tissue papers, napkins, cups, and glasses may have imprints of the suspect's lips. Thus, the full genetic profile is extremely useful for the forensic team. PMID:28123277

    2015-01-01

    While use of advanced visualization in radiology is instrumental in diagnosis and communication with referring clinicians, there is an unmet need to render Digital Imaging and Communications in Medicine (DICOM) images as three-dimensional (3D) printed models capable of providing both tactile feedback and tangible depth information about anatomic and pathologic states. Three-dimensional printed models, already entrenched in the nonmedical sciences, are rapidly being embraced in medicine as well as in the lay community. Incorporating 3D printing from images generated and interpreted by radiologists presents particular challenges, including training, materials and equipment, and guidelines. The overall costs of a 3D printing laboratory must be balanced by the clinical benefits. It is expected that the number of 3D-printed models generated from DICOM images for planning interventions and fabricating implants will grow exponentially. Radiologists should at a minimum be familiar with 3D printing as it relates to their field, including types of 3D printing technologies and materials used to create 3D-printed anatomic models, published applications of models to date, and clinical benefits in radiology. Online supplemental material is available for this article. (©)RSNA, 2015.

    Full Text Available Friction between different papers, inkjet and flexographic prints has been experimentally investigated. Flexographic prints have been made using an anilox roller, and inkjet prints have been produced covering paper with one and four toner layers. Static (SCOF and kinetic (KCOF friction coefficients between paper and paper, paper and prints, prints and prints have been determined. Friction properties have been discovered to be different in flexographic and laser prints. The dependence of SCOF and KCOF on pressure (both decrease together with roughness measurements enables to conclude that the friction of prints is mainly governed by adhesion forces.

    Efforts to adapt and extend graphic arts printing techniques for demanding device applications in electronics, biotechnology and microelectromechanical systems have grown rapidly in recent years. Here, we describe the use of electrohydrodynamically induced fluid flows through fine microcapillary nozzles for jet printing of patterns and functional devices with submicrometre resolution. Key aspects of the physics of this approach, which has some features in common with related but comparatively low-resolution techniques for graphic arts, are revealed through direct high-speed imaging of the droplet formation processes. Printing of complex patterns of inks, ranging from insulating and conducting polymers, to solution suspensions of silicon nanoparticles and rods, to single-walled carbon nanotubes, using integrated computer-controlled printer systems illustrates some of the capabilities. High-resolution printed metal interconnects, electrodes and probing pads for representative circuit patterns and functional transistors with critical dimensions as small as 1μm demonstrate potential applications in printed electronics.

    2015-07-01

    We propose a mechanism for reverse-offset printing based on a mathematical model. In reverse-offset printing, high resolution is achieved by patterning a coated, thin ink film with an intaglio-patterned cliché. By using the relationships among the ink blanket adhesion strength, the ink cliché adhesion strength, and the ink cohesion strength, a criterion for successful patterning is derived. We found that there is a printing window in the ink blanket adhesion strength that depends on the shear strength of the ink film and the dimensions of the pattern. The printing window diminishes as the line width decreases, resulting in a minimum printable line width. The proposed mechanism was verified by printing patterns with various shapes and dimensions.

    2016-10-10

    Three-dimensional (3D) printing is becoming an increasingly common technique to fabricate scaffolds and devices for tissue engineering applications. This is due to the potential of 3D printing to provide patient-specific designs, high structural complexity, rapid on-demand fabrication at a low-cost. One of the major bottlenecks that limits the widespread acceptance of 3D printing in biomanufacturing is the lack of diversity in "biomaterial inks". Printability of a biomaterial is determined by the printing technique. Although a wide range of biomaterial inks including polymers, ceramics, hydrogels and composites have been developed, the field is still struggling with processing of these materials into self-supporting devices with tunable mechanics, degradation, and bioactivity. This review aims to highlight the past and recent advances in biomaterial ink development and design considerations moving forward. A brief overview of 3D printing technologies focusing on ink design parameters is also included.

    In printed electronics technology, the overlay accuracy of printed patterns is a very important issue when applying printing technology to the production of electric devices. In order to achieve accurate positioning of the printed patterns, this study proposes a novel precision reverse offset printing system. Furthermore, the study evaluates the effects of synchronization and printing force on position errors of the printed patterns, and presents methods of controlling synchronization and printing force so as to eliminate positional errors caused by the above-mentioned reasons. Finally, the printing position repeatability of 0.40 μm and 0.32 μm (x and y direction, respectively) at a sigma level is obtained over the dimension of 100 mm under repeated printing tests with identical printing conditions.

  6. Evaluation of Mining Titles Based on Option-Pricing Model

    2006-01-01

    Limitations exist in applying discounted cash flow and analogy sales methods to evaluate mining titles. In order to find a more appropriate way of evaluating mining titles, the Black-Scholes model is discussed in this paper. The authors pay particular attention to the determination of the time to maturity of the option on the basis of characteristics of the mining industry, pointing out that a reasonable time to maturity of the option should be the remaining time after deducting the essential time, needed by exploitation of the mineral resources within the mining property, from the life of the mining title. Several conclusions, related to the exercise of mineral resource management, are drawn from a case study analysis; extending the life of a mining title within a certain range could increase the revenue to the seller of the mining title. Application of the Black-Scholes model to evaluate mining titles would encourage an expansion of the scale of production.

    This paper describes a new watermarking technique for printed images, using the texture synthesis method. In this aspect, a few techniques have been proposed, but those techniques are all based on FMS (Frequency modulated screening), which means high cost and additional difficulties in practice. On the other side the technique in this paper is based on AMS (Amplitude modulated screening). Ink dots are considered as texture patterns, and texture analysis is used to generate two corresponding texture patterns to describe ?A“1” and “0”. Another advantage of this technique is that the robustness and the unobtrusiveness of watermark can be easily controlled. Finally, the result of a simulation experiment is reported, which demonstrate that the method in this paper is effective and potential.

    Bollig, Lindsey; Otto, Austin; Hilpisch, Peter; Mowry, Greg; Nelson-Cheeseman, Brittany; Renewable Energy; Alternatives Lab (REAL) Team

    Transformers are ubiquitous in electronics today. Although toroidal geometries perform most efficiently, transformers are traditionally made with rectangular cross-sections due to the lower manufacturing costs. Additive manufacturing techniques (3D printing) can easily achieve toroidal geometries by building up a part through a series of 2D layers. To get strong magnetic properties in a 3D printed transformer, a composite filament is used containing Fe dispersed in a polymer matrix. How the resulting 3D printed toroid responds to a magnetic field depends on two structural factors of the printed 2D layers: fill factor (planar density) and fill pattern. In this work, we investigate how the fill factor and fill pattern affect the magnetic properties of 3D printed toroids. The magnetic properties of the printed toroids are measured by a custom circuit that produces a hysteresis loop for each toroid. Toroids with various fill factors and fill patterns are compared to determine how these two factors can affect the magnetic field the toroid can produce. These 3D printed toroids can be used for numerous applications in order to increase the efficiency of transformers by making it possible for manufacturers to make a toroidal geometry.

    2014-03-01

    3D printer applications in the biomedical sciences and medical imaging are expanding and will have an increasing impact on the practice of medicine. Orthopedic and reconstructive surgery has been an obvious area for development of 3D printer applications as the segmentation of bony anatomy to generate printable models is relatively straightforward. There are important issues that should be addressed when using 3D printed models for applications that may affect patient care; in particular the dimensional accuracy of the printed parts needs to be high to avoid poor decisions being made prior to surgery or therapeutic procedures. In this work, the dimensional accuracy of 3D printed vertebral bodies derived from CT data for a cadaver spine is compared with direct measurements on the ex-vivo vertebra and with measurements made on the 3D rendered vertebra using commercial 3D image processing software. The vertebra was printed on a consumer grade 3D printer using an additive print process using PLA (polylactic acid) filament. Measurements were made for 15 different anatomic features of the vertebral body, including vertebral body height, endplate width and depth, pedicle height and width, and spinal canal width and depth, among others. It is shown that for the segmentation and printing process used, the results of measurements made on the 3D printed vertebral body are substantially the same as those produced by direct measurement on the vertebra and measurements made on the 3D rendered vertebra.

While the translation of novel titles comes with first importance as successful translation of the titles facilitates a bird’s eye view of the whole context. However, the transla-tion of novel titles is no easy without consideration of cultural differences which directly influence people’s thoughts and under-standing. Therefore, translating novel titles requires an overall analysis of such cultural elements as religion, cultural images, way of thinking, and historical allusions.

    The video game plays an important role in inter-cultural communication studies. However, few have ventured the field of E-C translation of video game titles. Within the frame of Skopostheorie, this paper focuses on the three translation strategies brought up by the functions and features of video game titles. When preserving the structure and meaning of the original title is possible, literal translation should be used. However, the fact that some translators ignore the context of the title causes rigid translation. Transliteration is recommended when the title is the name of a person or place because the meaning of the title is hard to be preserved by the other two strategies. Since there are cultural differences between China and western world, when lit-eral translation and transliteration cannot present the meaning of the title, free translation should be used. Translators should bear the content and game play of the game in mind in order to free themselves from the formal equivalence for a properly translated title. Free translation does not mean translators can do the translation as whatever they want in the name of Skopos, they should avoid arbitrary translation. The aim of this paper is to help people to understand more about the E-C translation of video game ti-tle as well as the practical translation strategies and Sino-western inter-cultural communication.

    This paper provides an overview of an aerial 3D printing technology, its development and its testing. This technology is potentially useful in its own right. In addition, this work advances the development of a related in-space 3D printing technology. A series of aerial 3D printing test missions, used to test the aerial printing technology, are discussed. Through completing these test missions, the design for an in-space 3D printer may be advanced. The current design for the in-space 3D printer involves focusing thermal energy to heat an extrusion head and allow for the extrusion of molten print material. Plastics can be used as well as composites including metal, allowing for the extrusion of conductive material. A variety of experiments will be used to test this initial 3D printer design. High altitude balloons will be used to test the effects of microgravity on 3D printing, as well as parabolic flight tests. Zero pressure balloons can be used to test the effect of long 3D printing missions subjected to low temperatures. Vacuum chambers will be used to test 3D printing in a vacuum environment. The results will be used to adapt a current prototype of an in-space 3D printer. Then, a small scale prototype can be sent into low-Earth orbit as a 3-U cube satellite. With the ability to 3D print in space demonstrated, future missions can launch production hardware through which the sustainability and durability of structures in space will be greatly improved.

    We report a laser-based approach for the fast fabrication of high-optical-quality polymeric microlenses and microlens arrays with controllable geometry and size. Our strategy consists of the direct laser printing of microdroplets of a highly viscous UV prepolymer at targeted positions, followed by photocuring. We study the morphological characteristics and imaging performance of the microlenses as a function of the substrate and laser parameters and investigate optimal printing conditions and printing mechanisms. We show that the microlens size and focusing properties can be easily tuned by the laser pulse energy, with minimum volumes below 20 fL and focal lengths ranging from 7 to 50 μm.

    2015-12-01

    In 2013, the first gun printed out of plastic by a 3D-printer was successfully fired in the U.S. This event caused a major media hype about the dangers of being able to print a gun. Law enforcement agencies worldwide were concerned about this development and the potentially huge security implications of these functional plastic guns. As a result, politicians called for a ban of these weapons and a control of 3D-printing technology. This paper reviews the security implications of 3D-printing technology and 3D guns. It argues that current arms control and transfer policies are adequate to cover 3D-printed guns as well. However, while this analysis may hold up currently, progress in printing technology needs to be monitored to deal with future dangers pre-emptively.

    Flexible electroluminescent (EL) lamps are fabricated onto woven textiles using a novel dispenser printing process. Dispenser printing utilizes pressurized air to deposit ink onto a substrate through a syringe and nozzle. This work demonstrates the first use of this technology to fabricate EL lamps. The luminance of the dispenser printed EL lamps is compared to screen-printed EL lamps, both printed on textile, and also commercial EL lamps on polyurethane film. The dispenser printed lamps are shown to have a 1.5 times higher luminance than the best performing commercially available lamp, and have a comparable performance to the screen-printed lamps.

  12. Influence of printing speed on production of embossing tools using FDM 3D printing technology

    2017-06-01

    Full Text Available Manufacturing of the embossing tools customary implies use of metals such as zinc, magnesium, copper, and brass. In the case of short run lengths, a conventional manufacturing process and the material itself represent a significant cost, not only in the terms of material costs and the need for using complex technological systems which are necessary for their production, but also in the terms of the production time. Alternatively, 3D printing can be used for manufacturing similar embossing tools with major savings in production time and costs. However, due to properties of materials used in the 3D printing technology, expected results of embossing by 3D printed tools cannot be identical to metal ones. This problem is emphasized in the case of long run lengths and high accuracy requirement for embossed elements. The objective of this paper is primarily focused on investigating the influence of the printing speed on reproduction quality of the embossing tools printed with FDM (Fused Deposition Modelling technology. The obtained results confirmed that printing speed as a process parameter affects the reproduction quality of the embossing tools printed with FDM technology: in the case of deposition rate of 90 mm/s was noted the poorest dimensional accuracy in relation to the 3D model, which is more emphasised in case of circular and square elements. Elements printed with the highest printing speed have a greater dimensional accuracy, but with evident cracks on the surface.

    While 3D printing technologies first appeared in the 1980s, prohibitive costs, limited materials, and the relatively small number of commercially available printers confined applications mainly to prototyping for manufacturing purposes. As technologies, printer cost, materials, and accessibility continue to improve, 3D printing has found widespread implementation in research and development in many disciplines due to ease-of-use and relatively fast design-to-object workflow. Several 3D printing techniques have been used to prepare devices such as milli- and microfluidic flow cells for analyses of cells and biomolecules as well as interfaces that enable bioanalytical measurements using cellphones. This review focuses on preparation and applications of 3D-printed bioanalytical devices.

    3D printing, an upcoming technology, has vast potential to transform conventional fabrication processes due to the numerous improvements it can offer to the current methods. To date, the employment of 3D printing technology has been examined for applications in the fields of engineering, manufacturing and biological sciences. In this study, we examined the potential of adopting 3D printing technology for a novel application, electrochemical DNA biosensing. Metal 3D printing was utilized to construct helical-shaped stainless steel electrodes which functioned as a transducing platform for the detection of DNA hybridization. The ability of electroactive methylene blue to intercalate into the double helix structure of double-stranded DNA was then exploited to monitor the DNA hybridization process, with its inherent reduction peak serving as an analytical signal. The designed biosensing approach was found to demonstrate superior selectivity against a non-complementary DNA target, with a detection range of 1-1000 nM.

    Microfluidic automation – the automated routing, dispensing, mixing, and/or separation of fluids through microchannels – generally remains a slowly-spreading technology because device fabrication requires sophisticated facilities and the technology’s use demands expert operators. Integrating microfluidic automation in devices has involved specialized multi-layering and bonding approaches. Stereolithography is an assembly-free, 3D-printing technique that is emerging as an efficient alternative for rapid prototyping of biomedical devices. Here we describe fluidic valves and pumps that can be stereolithographically printed in optically-clear, biocompatible plastic and integrated within microfluidic devices at low cost. User-friendly fluid automation devices can be printed and used by non-engineers as replacement for costly robotic pipettors or tedious manual pipetting. Engineers can manipulate the designs as digital modules into new devices of expanded functionality. Printing these devices only requires the digital file and electronic access to a printer.

    We present a novel 3D printed multimaterial microfluidic proportional valve. The microfluidic valve is a fundamental primitive that enables the development of programmable, automated devices for controlling fluids in a precise manner. We discuss valve characterization results, as well as exploratory design variations in channel width, membrane thickness, and membrane stiffness. Compared to previous single material 3D printed valves that are stiff, these printed valves constrain fluidic deformation spatially, through combinations of stiff and flexible materials, to enable intricate geometries in an actuated, functionally graded device. Research presented marks a shift towards 3D printing multi-property programmable fluidic devices in a single step, in which integrated multimaterial valves can be used to control complex fluidic reactions for a variety of applications, including DNA assembly and analysis, continuous sampling and sensing, and soft robotics.

  12. Contextual advertisement placement in printed media

    Liu, Sam; Joshi, Parag

    2010-02-01

    Advertisements today provide the necessary revenue model supporting the WWW ecosystem. Targeted or contextual ad insertion plays an important role in optimizing the financial return of this model. Nearly all the current ads that appear on web sites are geared for display purposes such as banner and "pay-per-click". Little attention, however, is focused on deriving additional ad revenues when the content is repurposed for alternative mean of presentation, e.g. being printed. Although more and more content is moving to the Web, there are still many occasions where printed output of web content is desirable, such as maps and articles; thus printed ad insertion can potentially be lucrative. In this paper, we describe a contextual ad insertion network aimed to realize new revenue for print service providers for web printing. We introduce a cloud print service that enables contextual ads insertion, with respect to the main web page content, when a printout of the page is requested. To encourage service utilization, it would provide higher quality printouts than what is possible from current browser print drivers, which generally produce poor outputs, e.g. ill formatted pages. At this juncture we will limit the scope to only article-related web pages although the concept can be extended to arbitrary web pages. The key components of this system include (1) the extraction of article from web pages, (2) the extraction of semantics from article, (3) querying the ad database for matching advertisement or coupon, and (4) joint content and ad layout for print outputs.

    Developing countries are increasingly decentralizing forest governance by granting indigenous groups and other local communities formal legal title to land. However, the effects of titling on forest cover are unclear. Rigorous analyses of titling campaigns are rare, and related theoretical and empirical research suggests that they could either stem or spur forest damage. We analyze such a campaign in the Peruvian Amazon, where more than 1,200 indigenous communities comprising some 11 million ha have been titled since the mid-1970s. We use community-level longitudinal data derived from high-resolution satellite images to estimate the effect of titling between 2002 and 2005 on contemporaneous forest clearing and disturbance. Our results indicate that titling reduces clearing by more than three-quarters and forest disturbance by roughly two-thirds in a 2-y window spanning the year title is awarded and the year afterward. These results suggest that awarding formal land titles to local communities can advance forest conservation.

    In this study, electrochemical responses of inkjet-printed multicolored electrochromic devices (ECD) were studied to evaluate the feasibility of presenting multiple colors in one ECD. Metallo-supramolecular polymers (MEPE) solutions with two primary colors were inkjet-printed on flexible electrodes. By digitally controlling print dosages of each species, the colors of the printed EC thin film patterns can be adjusted directly without premixing or synthesizing new materials. The printed EC thin films were then laminated with a solid transparent thin film electrolyte and a transparent conductive thin film to form an ECD. After applying a dc voltage, the printed ECDs exhibited great contrast with a transmittance change (ΔT) of 40.1% and a high coloration efficiency of 445 cm(2) C(-1) within a short darkening time of 2 s. The flexible ECDs also showed the same darkening time of 2 s and still had a high ΔT of 30.1% under bending condition. This study demonstrated the feasibility to fabricate display devices with different color setups by an all-solution process and can be further extended to other types of displays.

  9. Direct Numerical Simulation of Cell Printing

    Qiao, Rui; He, Ping

    2010-11-01

    Structural cell printing, i.e., printing three dimensional (3D) structures of cells held in a tissue matrix, is gaining significant attention in the biomedical community. The key idea is to use desktop printer or similar devices to print cells into 3D patterns with a resolution comparable to the size of mammalian cells, similar to that in living organs. Achieving such a resolution in vitro can lead to breakthroughs in areas such as organ transplantation and understanding of cell-cell interactions in truly 3D spaces. Although the feasibility of cell printing has been demonstrated in the recent years, the printing resolution and cell viability remain to be improved. In this work, we investigate one of the unit operations in cell printing, namely, the impact of a cell-laden droplet into a pool of highly viscous liquids using direct numerical simulations. The dynamics of droplet impact (e.g., crater formation and droplet spreading and penetration) and the evolution of cell shape and internal stress are quantified in details.

  10. Cell Source for Tissue and Organ Printing

    Xu, Tao; Yuan, Yuyu; Yoo, James J.

    Organ printing, a novel approach in tissue engineering, applies computer-driven deposition of cells, growth factors, biomaterials layer-by-layer to create complex 3D tissue or organ constructs. This emerging technology shows great promise in regenerative medicine, because it may help to address current crisis of tissue and organ shortage for transplantation. Organ printing is developing fast, and there are exciting new possibilities in this area. Successful cell and organ printing requires many key elements. Among these, the choice of appropriate cells for printing is vital. This chapter surveys available cell sources for cell and organ printing application and discusses factors that affect cell choice. Special emphasis is put on several important factors, including the proposed printing system and bioprinters, the assembling method, and the target tissues or organs, which need to be considered to select proper cell sources and cell types. In this chapter, characterizations of the selected cells to justify and/or refine the cell selection will also be discussed. Finally, future prospects in this field will be envisioned.

    Directory of Open Access Journals (Sweden)

    Murugan

    2014-10-01

    Full Text Available BACKGROUND AND OBJECTIVE: The use of conventional methods such as dactylography (study of finger prints & cheiloscopy (study of lip prints is of paramount importance, since personal identification by other means such as DNA analysis is sophisticated and not available in rural and developing countries. Fingerprint in its narrow sense is an impression left by the friction ridges of human fingers. The second prints of interest are lip prints. Studies of association between finger print and lip prints are scanty in literature. The present study was aimed to analyze the predominant pattern of lip and finger prints and to identify whether there is any correlation between these two parameters. MATERIALS AND METHODS: The study sample included 300 college students. Brown/pink colored lip stick was applied on the lips and the subject was asked to spread it uniformly over the lips by gentle movement of the lips. The unglazed white paper was then pressed uniformly over the lips. After the fingers were cleaned with tissue paper, the subjects were instructed to roll the tip of their fingers across the surface of an already made ink-stained pad, ensuring that the ink covered the entire pattern area. The inked finger was then enrolled over a white paper to obtain the print and analyzed using magnified hand lens. These prints were examined using magnifying glass, classified, and analyzed. The data was statistically analyzed by using Chi-square test. RESULTS: The percentage distribution of lip print shows that the most frequent lip print pattern in the male is Type I (36.8% and in female it is type II (34.4%. There is no statistically significant association between the pattern of finger prints and lip prints (p value = 0.9. CONCLUSION: It is known that individual parameters, i.e., lip print and finger print patterns play an important role in forensic identification. Correlation of these two parameters in our study did not show any significant association, hence

    2017-06-01

    Full Text Available Fountain solution system in offset printing system has significant impacts on the printing quality and fountain is the indispensable part of this system. The most important chemical added into the fountain solution is isopropyl alcohol. Fundamental features of isopropyl alcohol are reducing surface tension and adjusting and stabilizing pH. However, in the course of time, the disadvantages of using alcohol have emerged. In the present study, the quality levels of IPA-based and IPA-free offset prints were compared. Specially designed test scale printing was carried out after IPA-based and IPA-free fountain solutions were prepared with the same ink on matt-coated paper under optimal printing conditions. Densitometric and spectrophotometric measurements were carried out on the prints and it was ensured that they were printed in accordance with ISO-12647-2:2013 offset printing standards. Special test scales that were printed were read through scale readers and colour profiles were obtained. Comparisons were carried out on the obtained IPA-free and IPAbased printing colour gamut. Microscopic images of the smallest dots were taken and edge sharpening was examined. Print brightness measurements were carried out for the selected areas on the test scale. The study practically demonstrated that printing performed by using IPA-free fountain solution produced a better and wider colour gamut, edge sharpening was better in the IPA-free systems as the number of prints increased and the prints made by using IPA-free fountain solution were brighter.

  20. Inscribing Authority: Female Title Bearers in Jewish Inscriptions

    Directory of Open Access Journals (Sweden)

    Carrie Duncan

    2012-02-01

    Full Text Available This paper investigates representations of gender in the material culture of the ancient synagogue. The pertinent data are numerous dedicatory and funerary inscriptions linking individual Jews, men and women, with titles seemingly associated with leadership in Late Antique synagogues (ca. 200–600 CE. Bernadette Brooten’s influential 1982 monograph argued against the prevailing tendency to characterize these titles as indications of power, authority, and responsibility when associated with men but as meaningless flattery when applied to women. She suggests that synagogue titles denote power, authority and responsibility on all title bearers equally, both men and women. I question the continued utility of proffering female title-holders as enumerable examples of powerful women rescued from their forgotten place in history. Using theoretical insights developed by historians Elizabeth Clark and Gabrielle Spiegel, this paper will engage a comparative analysis with the work of Riet van Bremen and Saba Mahmood to develop new methods of conceptualizing women’s authority in early Jewish communities. I propose that viewing women’s synagogue titles as culturally constructed representations allows for a fruitful inquiry into how women’s titles were used by male-dominated synagogue communities in their self-articulation and public presentation of Judaism.

    2003-07-01

    The Florida State University (FSU) College of Medicine Medical Library is the first academic medical library to be established since the Web's dramatic appearance during the 1990s. A large customer base for electronic medical information resources is both comfortable with and eager to migrate to the electronic format completely, and vendors are designing radical pricing models that make print journal cancellations economically advantageous. In this (almost) post-print environment, the new FSU Medical Library is being created and will continue to evolve. By analyzing print journal subscription lists of eighteen academic medical libraries with similar missions to the community-based FSU College of Medicine and by entering these and selected quality indicators into a Microsoft Access database, a core list was created. This list serves as a selection guide, as a point for discussion with faculty and curriculum leaders when creating budgets, and for financial negotiations in a broader university environment. After journal titles specific to allied health sciences, veterinary medicine, dentistry, pharmacy, library science, and nursing were eliminated from the list, 4,225 unique journal titles emerged. Based on a ten-point scale including SERHOLD holdings and DOCLINE borrowing activity, a list of 449 core titles is identified. The core list has been saved in spreadsheet format for easy sorting by a number of parameters.

  4. Using print focused collection development policies in digitally born libraries: dilemmas. Which dies first: the print or the print CDP?

    KAUST Repository

    Buck, Stephen

    2016-11-03

    Objectives: The King Abdullah University of Science & Technology (KAUST) library is a ‘born digital’ library. The core, and vast majority, of library resources was acquired in electronic form and a smaller print collection, which complemented the wider collection, was acquired contemporaneously. The purpose of this paper is to determine whether, in conjunction with our specific print collections development policy, we need a complementary E-Resources policy. The writing of such a policy utilizes valuable resources (both staff and time) and involves itself with the sometimes vaguely defined and complex concept of collection evaluation. Issues in e-resources are constantly changing and updates will be necessary to reflect this. How, and how often, do we update our E-Resources CDP? While Biblarz (2001) maintains that the main argument for the existence of a print CDP is to prevent the library from being driven by events or by individual enthusiasms and from purchasing a random set of resources, which may not support the mission of the library this paper explores issues in maintaining a joint print and ‘E’ CDP. Methodology: This case study of KAUST University Library discusses our print and E-collections in the context of the vision and mission of the university. While the research on crossover, between print and E-Resource CDPs is scarce, on studying a cross section of other university library CDPs it can be seen that the print CDP, which was formerly a main driver of library policy, is now overwhelmingly no more than a minor subsection of the overall CDPs of many libraries. Two IFLA documents were also compared in their approaches to dealing with print and ‘E’ CDPs. Key Issues for E-Resource Collection Development (Johnson, 2012) focuses on key aspects of the e-resource process in libraries. Crucially it is stated that the current document is simply a snapshot of best practices at this point in time. The 2001 IFLA Guidelines for a Collection Development

    An effective way to improve the electrical conductivity of printed graphene patterns was demonstrated by realizing the assembly of giant graphene oxide sheets during the printing process. The synergetic effect of printing-induced orientation and evaporation-induced interfacial assembly facilitated the formation of laminar-structured patterns. The resulting patterns after chemical reduction showed excellent electrical conductivity in printed graphene electronics. Because of their high conductivity, mechanical flexibility, and advantage in pattern design, printed graphene electrodes were applied in electrical-driven soft actuators, which can realize controllable deformation with low driving voltage. Such achievements will be of great significance for the development of graphene-based flexible and printed electronics.

    Full Text Available Printing is offering the feasibility of producing mass quantities of a wide variety of electronic components and devices quickly and at lower cost. Flexography is mainly used for packaging applications, but is also poses a potential method for the micro manufacture of electronic devices, smart packaging and RFID. The flexographic printing process poses as an attractive candidate for printing electronics for its high speed printing capabilities where such volume and large active areas need to be printed. Therefore an investigation for its potential usage in printing electronics are highly in demand hence a research for suitable conductive ink related to this process is vital. Multiple fine solid lines of high quality are essential to enable printing of ink tracks for electronic applications. A step by step approach by printing multiple solid lines, measurements of printing plates and printed images and finite element analysis (FEA need to be carried out in advance to help comprehending this process that is influenced by many interacting parameters. Plate characteristics are among a number of process parameters that will influence print line quality, which will affect the electrical performance of printed tracks. Printing trials have also been carried out in comparison various ink to check the compatibility and the suitability of the ink developed for printing RFID antennas.

    Three dimensional printing technology is gaining in importance because of its increasing availability and wide applications. One of the three dimensional printing techniques is Fused Deposition Modelling (FDM) which works on the basis of hot melt extrusion-well known in the pharmaceutical technology. Combination of fused deposition modelling with preparation of the orodispersible film with poorly water soluble substance such as aripiprazole seems to be extra advantageous in terms of dissolution rate. 3D printed as well as casted films were compared in terms of physicochemical and mechanical properties. Moreover, drug-free films were prepared to evaluate the impact of the extrusion process and aripiprazole presence on the film properties. X-ray diffractometry and thermal analyses confirmed transition of aripiprazole into amorphous state during film preparation using 3D printing technique. Amorphization of the aripiprazole and porous structure of printed film led to increased dissolution rate in comparison to casted films, which, however have slightly better mechanical properties due to their continuous structure. It can be concluded that fused deposition modelling is suitable technique and polyvinyl alcohol is applicable polymer for orodispersible films preparation. Copyright © 2017 Elsevier B.V.

    An automated metal powder three-dimensional (3D) printing method for in situ synthesis of free-standing 3D graphene foams (GFs) was successfully modeled by manually placing a mixture of Ni and sucrose onto a platform and then using a commercial CO2 laser to convert the Ni/sucrose mixture into 3D GFs. The sucrose acted as the solid carbon source for graphene, and the sintered Ni metal acted as the catalyst and template for graphene growth. This simple and efficient method combines powder metallurgy templating with 3D printing techniques and enables direct in situ 3D printing of GFs with no high-temperature furnace or lengthy growth process required. The 3D printed GFs show high-porosity (∼99.3%), low-density (∼0.015g cm(-3)), high-quality, and multilayered graphene features. The GFs have an electrical conductivity of ∼8.7 S cm(-1), a remarkable storage modulus of ∼11 kPa, and a high damping capacity of ∼0.06. These excellent physical properties of 3D printed GFs indicate potential applications in fields requiring rapid design and manufacturing of 3D carbon materials, for example, energy storage devices, damping materials, and sound absorption.

    Full Text Available There is scant literature where applied sport scientists have considered first hand experiences preparing professional boxers for world title bouts. The present submission reflects more than 10 years of applied experience working with professional boxers, residing in Canada. What follows is a composite of sequential steps that ownership and coaching staff of one Canadian management group have tried leading up to more than 20 world title bout experiences. The strategies proposed have been built progressively over time, and what follows is a general overview of a more detailed pre-bout structure from shortly in advance of a world title bout offer to the moment when the athlete enters the ring to perform. We propose that an effective structure is founded upon detailed a priori preparation, tactical decisions throughout bout preparation, and a thorough understanding by the athlete of what he will encounter during the title bout

    Microfluidics is a flourishing field, enabling a wide range of biochemical and clinical applications such as cancer screening, micro-physiological system engineering, high-throughput drug testing, and point-of-care diagnostics. However, fabrication of microfluidic devices is often complicated, time consuming, and requires expensive equipment and sophisticated cleanroom facilities. Three-dimensional (3D) printing presents a promising alternative to traditional techniques such as lithography and PDMS-glass bonding, not only by enabling rapid design iterations in the development stage, but also by reducing the costs associated with institutional infrastructure, equipment installation, maintenance, and physical space. With the recent advancements in 3D printing technologies, highly complex microfluidic devices can be fabricated via single-step, rapid, and cost-effective protocols, making microfluidics more accessible to users. In this review, we discuss a broad range of approaches for the application of 3D printing technology to fabrication of micro-scale lab-on-a-chip devices.

  3. Condition monitoring of multistage printing presses

    Wang, W.; Golnaraghi, F.; Ismail, F.

    2004-03-01

    The main concern in printing quality in multistage presses is doubling. Doubling is caused by imperfections either within stages (units) or in links connecting different stages, mainly resulting from machine vibration, gear damage, and excessive run-out. In this paper, we propose new means for printing quality control via geared system health condition monitoring. The diagnosis is based on the signals acquired from inexpensive magnetic pickups. A new technique is developed to monitor the gear rotation synchronization among different stages in order to isolate possible sources of the doubling problem. A new approach is proposed to determine the gear run-out. Moreover, gear tooth damage detection is conducted using the beta kurtosis and the continuous wavelet transform based on the overall residual signal. The beta kurtosis of original signal average is also shown here to be useful in detecting excessive gear run-out. Test results from printing presses demonstrated the viability of the proposed methods.

    A thermal flow sensor was printed on a flexible plastic substrate using exclusively screen-printing techniques. The presented device was implemented with custom made screen-printed thermistors, which allows simple, cost-efficient production on a variety of flexible substrates while maintaining the typical advantages of thermal flow sensors. Evaluation was performed for both static (zero flow) and dynamic conditions using a combination of electrical measurements and IR imaging techniques in order to determine important characteristics, such as temperature response, output repeatability, etc. The flow sensor was characterized utilizing the hot-wire and calorimetric principles of operation, while the preliminary results appear to be very promising, since the sensor was successfully evaluated and displayed adequate sensitivity in a relatively wide flow range.

    Full Text Available With the advent of additive manufacturing technologies in the mid 1980s, many applications benefited from the faster processing of products without the need for specific tooling or dies. However, the application of such techniques in the area of biomedical devices has been slow due to the stringent performance criteria and concerns related to reproducibility and part quality, when new technologies are in their infancy. However, the use of additive manufacturing technologies in bone tissue engineering has been growing in recent years. Among the different technology options, three dimensional printing (3DP is becoming popular due to the ability to directly print porous scaffolds with designed shape, controlled chemistry and interconnected porosity. Some of these inorganic scaffolds are biodegradable and have proven ideal for bone tissue engineering, sometimes even with site specific growth factor/drug delivery abilities. This review article focuses on recent advances in 3D printed bone tissue engineering scaffolds along with current challenges and future directions.

  10. Inkjet Printed Radio Frequency Passive Components

    2015-12-01

    Inkjet printing is a mature technique for colourful graphic arts. It excels at customized, large area, high resolution, and small volume production. With the developments in conductive, and dielectric inks, there is potential for large area inkjet electronics fabrication. Passive radio frequency devices can benefit greatly from a printing process, since the size of these devices is defined by the frequency of operation. The large size of radio frequency passives means that they either take up expensive space “on chip” or that they are fabricated on a separate lower cost substrate and somehow bonded to the chips. This has hindered cost-sensitive high volume applications such as radio frequency identification tags. Substantial work has been undertaken on inkjet-printed conductors for passive antennas on microwave substrates and even paper, yet there has been little work on the printing of the dielectric materials aimed at radio frequency passives. Both the conductor and dielectric need to be integrated to create a multilayer inkjet printing process that is capable of making quality passives such as capacitors and inductors. Three inkjet printed dielectrics are investigated in this thesis: a ceramic (alumina), a thermal-cured polymer (poly 4 vinyl phenol), and a UV-cured polymer (acrylic based). For the conductor, both a silver nanoparticle ink as well as a custom in-house formulated particle-free silver ink are explored. The focus is on passives, mainly capacitors and inductors. Compared to low frequency electronics, radio frequency components have additional sensitivity regarding skin depth of the conductor and surface roughness, as well as dielectric constant and loss tangent of the dielectric. These concerns are investigated with the aim of making the highest quality components possible and to understand the current limitations of inkjet-fabricated radio frequency devices.

    Micro- and nanoscale structures are of interest in various engineering fields due to their unique properties, such as hydrophobicity. In particular, micro/nano hierarchical structures have been investigated to promote surface hydrophobicity. Here, aerodynamically focused nanoparticle (AFN) printing was used for direct printing of superhydrophobic patterns. As AFN printing is a room-temperature direct printing technique, printed features have a hierarchical structure of two levels; nanoscale porous surface and microscale-printed patterns in three-dimensional structures. Moreover, because it is an additive fabrication technique, the printed pattern is repairable and can be reconfigured as desired. In this study, silver nanoparticles were used to implement a superhydrophobic pattern with a minimum width of tens of microns. The contact angle of water droplets was measured for various patterns, and the effects of nanoscale porosity and pattern interval were investigated. In addition, patterns were designed and fabricated to have anisotropic superhydrophobicity. The experimental results were analyzed and explained with the classical Wenzel and Cassie-Baxter models.

    2015-01-01

    Full Text Available In order to produce nanophotonic elements for smart packaging, we investigated the influence of the parameters of screen and offset gravure printing plates on features of printed application of coatings with nanophotonic components and on parameters of their photoluminescence. To determine the dependence of luminescence intensity on the thickness of solid coating, we carried out the formation of nanophotonic solid surfaces by means of screen printing with different layer thickness on polypropylene film. The obtained analytical dependencies were used to confirm the explanation of the processes that occur during the fabrication of nanophotonic coverings with offset gravure printing plates. As a result of experimental studies, it was determined that the different character of the dependency of total luminescence intensity of nanophotonic elements from the percentage of a pad is explained by the use of different types of offset gravure printing plates, where the size of raster points remains constant in one case and changes in the other case, while the depth of the printing elements accordingly changes or remains constant. To obtain nanophotonic areas with predetermined photoluminescent properties, the influence of investigated factors on changes of photoluminescent properties of nanophotonic printed surfaces should be taken into consideration.

  15. Fluid mechanical proximity effects in high-resolution gravure printing for printed electronics

    Grau, Gerd; Scheideler, William J.; Subramanian, Vivek

    2016-11-01

    Gravure printing is a very promising method for printed electronics because it combines high throughput with high resolution. Recently, printed lines with 2 micrometer resolution have been demonstrated at printing speeds on the order of 1m/s. In order to build realistic circuits, the fluid dynamics of complex pattern formation needs to be studied. Recently, we showed that highly-scaled lines printed in close succession exhibit proximity effects that can either improve or deteriorate print quality depending on a number of parameters. It was found that this effect occurs if cells are connected by a thin fluid film. Here, we present further experimental and modeling results explaining the mechanism by which this thin fluid film affects pattern formation. During the transfer of ink from the roll to the substrate, ink can flow in between connected cells. Asymmetry in the fluid distribution created by the preceding doctor blade wiping process results in net fluid flow from cells that transfer first to cells that transfer subsequently. The proximity of these cells thus affects the final ink distribution on the substrate, which is critically important to understand and design optimally when printing highly-scaled patterns of electronic materials.

Despite the predictions of the impending death of print periodicals, more than half of the world adult population read a daily newspaper. At the same time, the trends taking place in the media market, confirm the reduction of print media segment in favor of the Internet. According to TNS-Russia data, only in 2013 the Internet audience has grown by 6 %. At the same time the circulation of print media in the US fell by 15 % in 2008- 2014, in Western Europe – by a quarter.

    Summary Medical 3D printing is emerging as a clinically relevant imaging tool in directing preoperative and intraoperative planning in many surgical specialties and will therefore likely lead to interdisciplinary collaboration between engineers, radiologists, and surgeons. Data from standard imaging modalities such as CT, MRI, echocardiography and rotational angiography can be used to fabricate life-sized models of human anatomy and pathology, as well as patient-specific implants and surgical guides. Cardiovascular 3D printed models can improve diagnosis and allow for advanced pre-operative planning. The majority of applications reported involve congenital heart diseases, valvular and great vessels pathologies. Printed models are suitable for planning both surgical and minimally invasive procedures. Added value has been reported toward improving outcomes, minimizing peri-operative risk, and developing new procedures such as transcatheter mitral valve replacements. Similarly, thoracic surgeons are using 3D printing to assess invasion of vital structures by tumors and to assist in diagnosis and treatment of upper and lower airway diseases. Anatomic models enable surgeons to assimilate information more quickly than image review, choose the optimal surgical approach, and achieve surgery in a shorter time. Patient-specific 3D-printed implants are beginning to appear and may have significant impact on cosmetic and life-saving procedures in the future. In summary, cardiothoracic 3D printing is rapidly evolving and may be a potential game-changer for surgeons. The imager who is equipped with the tools to apply this new imaging science to cardiothoracic care is thus ideally positioned to innovate in this new emerging imaging modality. PMID:27149367

    The use of single crystals has been fundamental to the development of semiconductor microelectronics and solid-state science. Whether based on inorganic or organic materials, the devices that show the highest performance rely on single-crystal interfaces, with their nearly perfect translational symmetry and exceptionally high chemical purity. Attention has recently been focused on developing simple ways of producing electronic devices by means of printing technologies. `Printed electronics' is being explored for the manufacture of large-area and flexible electronic devices by the patterned application of functional inks containing soluble or dispersed semiconducting materials. However, because of the strong self-organizing tendency of the deposited materials, the production of semiconducting thin films of high crystallinity (indispensable for realizing high carrier mobility) may be incompatible with conventional printing processes. Here we develop a method that combines the technique of antisolvent crystallization with inkjet printing to produce organic semiconducting thin films of high crystallinity. Specifically, we show that mixing fine droplets of an antisolvent and a solution of an active semiconducting component within a confined area on an amorphous substrate can trigger the controlled formation of exceptionally uniform single-crystal or polycrystalline thin films that grow at the liquid-air interfaces. Using this approach, we have printed single crystals of the organic semiconductor 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene (C8-BTBT) (ref. 15), yielding thin-film transistors with average carrier mobilities as high as 16.4cm2V-1s-1. This printing technique constitutes a major step towards the use of high-performance single-crystal semiconductor devices for large-area and flexible electronics applications.

Patient-specific 3D-printed implants are beginning to appear and may have significant impact on cosmetic and life-saving procedures in the future. In summary, cardiothoracic 3D printing is rapidly evolving and may be a potential game-changer for surgeons. The imager who is equipped with the tools to apply this new imaging science to cardiothoracic care is thus ideally positioned to innovate in this new emerging imaging modality.

    The use of laser-induced forward transfer (LIFT) techniques for the printing of functional materials has been demonstrated for numerous applications. The printing gives rise to patterns, which can be used to fabricate planar interconnects. More recently, various groups have demonstrated electrical interconnects from laser-printed 3D structures. The laser printing of these interconnects takes place through aggregation of voxels of either molten metal or of pastes containing dispersed metallic particles. However, the generated 3D structures do not posses the same metallic conductivity as a bulk metal interconnect of the same cross-section and length as those formed by wire bonding or tab welding. An alternative is to laser transfer entire 3D structures using a technique known as lase-and-place. Lase-and-place is a LIFT process whereby whole components and parts can be transferred from a donor substrate onto a desired location with one single laser pulse. This paper will describe the use of LIFT to laser print freestanding, solid metal foils or beams precisely over the contact pads of discrete devices to interconnect them into fully functional circuits. Furthermore, this paper will also show how the same laser can be used to bend or fold the bulk metal foils prior to transfer, thus forming compliant 3D structures able to provide strain relief for the circuits under flexing or during motion from thermal mismatch. These interconnect "ridges" can span wide gaps (on the order of a millimeter) and accommodate height differences of tens of microns between adjacent devices. Examples of these laser printed 3D metallic bridges and their role in the development of next generation electronics by additive manufacturing will be presented.

    The development of organic electronic requires a non contact digital printing process. The European funded e-LIFT project investigated the possibility of using the Laser Induced Forward Transfer (LIFT) technique to address this field of applications. This process has been optimized for the deposition of functional organic and inorganic materials in liquid and solid phase, and a set of polymer dynamic release layer (DRL) has been developed to allow a safe transfer of a large range of thin films. Then, some specific applications related to the development of heterogeneous integration in organic electronics have been addressed. We demonstrated the ability of LIFT process to print thin film of organic semiconductor and to realize Organic Thin Film Transistors (OTFT) with mobilities as high as 4 10-2 cm2.V-1.s-1 and Ion/Ioff ratio of 2.8 105. Polymer Light Emitting Diodes (PLED) have been laser printed by transferring in a single step process a stack of thin films, leading to the fabrication of red, blue green PLEDs with luminance ranging from 145 cd.m-2 to 540 cd.m-2. Then, chemical sensors and biosensors have been fabricated by printing polymers and proteins on Surface Acoustic Wave (SAW) devices. The ability of LIFT to transfer several sensing elements on a same device with high resolution allows improving the selectivity of these sensors and biosensors. Gas sensors based on the deposition of semiconducting oxide (SnO2) and biosensors for the detection of herbicides relying on the printing of proteins have also been realized and their performances overcome those of commercial devices. At last, we successfully laser-printed thermoelectric materials and realized microgenerators for energy harvesting applications.

  2. Color management: printing processes - opportunities and limitations

    2002-06-01

    Digital tools have impacted traditional methods employed to reproduce color images during the past decade. The shift from a purely photomechanical process in color reproduction to colorimetric reproduction offers tremendous opportunity in the graphic arts industry. But good things do not necessarily come to all in the same package. Printing processes possess different reproduction attributes: tone reproduction, gray balance and color correction requirements are as different as the ingredient sets selected for color reproduction. This paper will provide insight toward understanding advantages and limitations offered by the new digital technologies in printing, publishing and packaging. For the past five years the Clemson University Graphic Communications Department has conducted numerous color projects using the new digital colorimetric tools during the previous decade. Several approaches have been used including experimental research and typical production workflows. The use of colorimetric data in color reproduction has given an opportunity to realize real gains in color use, predictability and consistency. Meeting an image's separation and reproduction requirements for a specified printing process can involve disruption of the anticipated workflow. Understanding the printing process requirements and the fit within the specifications of a colorimetric workflow are critical to the successful adoption of a color managed workflow. The paper will also provide an insight into the issues and challenges experienced with a color managed workflow. The printing processes used include offset litho, narrow and wide-web flexography (paper, liner board, corrugated and film), screen printing (paper board and polycarbonates), and digital imaging with toner, ink and inkjet systems. A proposal for technology integration will be the focus of the presentation drawn from documented experiences in over 300 applications of color management tools. Discussion will include the structure of

    Full Text Available Raising of problem. Today, in all spheres of our life we can constate the permanent search for new, modern methods and technologies that meet the principles of sustainable development. New approaches need to be, on the one hand more effective in terms of conservation of exhaustible resources of our planet, have minimal impact on the environment and on the other hand to ensure a higher quality of the final product. Construction is not exception. One of the new promising technology is the technology of 3D -printing of individual structures and buildings in general. 3Dprinting - is the process of real object recreating on the model of 3D. Unlike conventional printer which prints information on a sheet of paper, 3D-printer allows you to display three-dimensional information, i.e. creates certain physical objects. Currently, 3D-printer finds its application in many areas of production: machine building elements, a variety of layouts, interior elements, various items. But due to the fact that this technology is fairly new, it requires the creation of detailed and accurate technologies, efficient equipment and materials, and development of common vocabulary and regulatory framework in this field. Research Aim. The analysis of existing methods of creating physical objects using 3D-printing and the improvement of technology and equipment for the printing of buildings and structures. Conclusion. 3D-printers building is a new generation of equipment for the construction of buildings, structures, and structural elements. A variety of building printing technics opens up wide range of opportunities in the construction industry. At this stage, printers design allows to create low-rise buildings of different configurations with different mortars. The scientific novelty of this work is to develop proposals to improve the thermal insulation properties of constructed 3D-printing objects and technological equipment.

    An OVJP apparatus and method for applying organic vapor or other flowable material to a substrate using a printing head mechanism in which the print head spacing from the substrate is controllable using a cushion of air or other gas applied between the print head and substrate. The print head is mounted for translational movement towards and away from the substrate and is biased toward the substrate by springs or other means. A gas cushion feed assembly supplies a gas under pressure between the print head and substrate which opposes the biasing of the print head toward the substrate so as to form a space between the print head and substrate. By controlling the pressure of gas supplied, the print head separation from the substrate can be precisely controlled.

  14. Aboriginal Determination: Native Title Claims and Barriers to Recognition

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available The Australian government has proposed a referendum in 2012 to decide the constitutional status of its indigenous people. There is at present no mechanism to define the indigenous people as a domestic or foreign entity of the Commonwealth. This is an important issue because other settler governments have developed a framework to implement their relationship with the native people. As a result, it is difficult prove title to land that has been abrogated by the deeds of the settlers. In Mabo v Queensland (2,the Commonwealth government was found to have breached its fiduciary duty to the Aboriginal peoples. The judgment led to the Native Title Act 1993 that established the process of asserting native rights that were held to coexist with pastoral ownership. The promulgation of the Native Title Amendment Act 1998 reversed this process and augmented the powers of non-native landlords by providing the device to extinguish native rights. In Western Australia v Ward, a mining lease was held to have precedence over native title that was adjudged to be part of a bundle of rights. In implementing the Native Title Act the issue turns on the determination of the ties to land/ sea that the government allows to the Aboriginal peoples. The judgment in Harrington-Smith on behalf of the Wongatha People v Western Australia indicates that title can be excluded on procedural grounds and that there was an incompatibility between the claims of the Aboriginal peoples and the settlers’ claims. The road map towards a more effective regime of proving title can be achieved if the Aboriginal peoples are granted recognition as a nation in the Constitution and a treaty is signed with them.

    2003-09-01

    Thermal transfer printing refers to printing processes that utilize heat to produce an image by either physical or chemical means or by a combination of both. As the technology has improved and the supplies have become less expensive, the use of thermal printing in the personal and business markets has increased significantly. Specifically, dye diffusion thermal transfer and thermal mass transfer have become predominant in the production of counterfeit credit cards, drivers' licenses, and other types of documents produced on plastic media. Chemical analysis by means of thin layer chromatography (TLC) has proven to be useful in characterizing various types of inks (e.g., writing and inkjet inks). In this study, the authors examined 81 different samples that included a total of 54 printer samples (43 photographic prints on paper and eleven plastic card samples) and 27 printer ribbons. A new TLC method was developed and tested utilizing a solvent system (80% n-hexane, 3% methyl ethyl ketone, and 17% ethyl acetate) that is capable of producing excellent resolution.

    In this paper, we examined how printing the hollow objects without infill via fused deposition modeling, one of the most widely used 3D-printing technologies, by partitioning the objects to shell parts. More specifically, we linked the partition to the exact cover problem. Given an input watertight mesh shape S, we developed region growing schemes to derive a set of surfaces that had inside surfaces that were printable without support on the mesh for the candidate parts. We then employed Monte Carlo tree search over the candidate parts to obtain the optimal set cover. All possible candidate subsets of exact cover from the optimal set cover were then obtained and the bounded tree was used to search the optimal exact cover. We oriented each shell part to the optimal position to guarantee the inside surface was printed without support, while the outside surface was printed with minimum support. Our solution can be applied to a variety of models, closed-hollowed or semi-closed, with or without holes, as evidenced by experiments and performance evaluation on our proposed algorithm.

    We have designed, constructed and characterized a grating that focuses electromagnetic radiation at specific frequencies out of a dielectric waveguide. A simple theoretical model predicts the focusing behaviour of these chirped gratings, along with numerical results that support our assumptions and improved the grating geometry. The leaky waveguide was 3D printed and characterized at 120 GHz demonstrating its potential for manipulating terahertz waves.

    3D printing as a tool to generate complicated shapes from CAD files, on demand, with different materials from plastics to metals, is shortening product development cycles, enabling new design possibilities and can provide a mean to manufacture small volumes cost effectively. There are many technologies for 3D printing and the majority uses light in the process. In one process (Multi-jet modeling, polyjet, printoptical©), a printhead prints layers of ultra-violet curable liquid plastic. Here, each nozzle deposits the material, which is then flooded by a UV curing lamp to harden it. In another process (Stereolithography), a focused UV laser beam provides both the spatial localization and the photo-hardening of the resin. Similarly, laser sintering works with metal powders by locally melting the material point by point and layer by layer. When the laser delivers ultra-fast focused pulses, nonlinear effects polymerize the material with high spatial resolution. In these processes, light is either focused in one spot and the part is made by scanning it or the light is expanded and covers a wide area for photopolymerization. Hence a fairly "simple" light field is used in both cases. Here, we give examples of how "complex light" brings additional level of complexity in 3D printing.

  4. International Standards on stability of digital prints

    Adelstein, Peter Z.

    2010-06-01

    The International Standards Organization (ISO) is a worldwide recognized standardizing body which has responsibility for standards on permanence of digital prints. This paper is an update on the progress made to date by ISO in writing test methods in this area. Three technologies are involved, namely ink jet, dye diffusion thermal transfer (dye-sublimation) and electrophotography. Two types of test methods are possible, namely comparative tests and predictive tests. To date a comparative test on water fastness has been published and final balloting is underway on a comparative test on humidity fastness. Predictive tests are being finalized on thermal stability and pollution susceptibility. The test method on thermal stability is intended to predict the print life during normal aging. One of the testing concerns is that some prints do not show significant image change in practical testing times. The test method on pollution susceptibility only deals with ozone and assumes that the reciprocity law applies. This law assumes that a long time under a low pollutant concentration is equivalent to a short time under the high concentration used in the test procedure. Longer term studies include a predictive test for light stability and the preparation of a material specification. The latter requires a decision about the proper colour target to be used and what constitutes an unacceptable colour change. Moreover, a specification which gives a predictive life is very dependent upon the conditions the print encounters and will only apply to specific levels of temperature, ozone and light.

    2015-04-29

    Electronically complementary, low molecular weight polymers that self-assemble through tunable π-π stacking interactions to form extended supramolecular polymer networks have been developed for inkjet printing applications and successfully deposited using three different printing techniques. Sequential overprinting of the complementary components results in supramolecular network formation through complexation of π-electron rich pyrenyl or perylenyl chain-ends in one component with π-electron deficient naphthalene diimide residues in a chain-folding polyimide. The complementary π-π stacked polymer blends generate strongly colored materials as a result of charge-transfer absorption bands in the visible spectrum, potentially negating the need for pigments or dyes in the ink formulation. Indeed, the final color of the deposited material can be tailored by varying the end-groups of the π-electron rich polymer component. Piezoelectric printing techniques were employed in a proof of concept study to allow characterization of the materials deposited, and a thermal inkjet printer adapted with imaging software enabled in situ analysis of the ink drops as they formed and of their physical properties. Finally, continuous inkjet printing allowed greater volumes of material to be deposited, on a variety of different substrate surfaces, and demonstrated the utility and versatility of this novel type of ink for industrial applications.

  1. DNA Assembly in 3D Printed Fluidics.

    William G Patrick

    Full Text Available The process of connecting genetic parts-DNA assembly-is a foundational technology for synthetic biology. Microfluidics present an attractive solution for minimizing use of costly reagents, enabling multiplexed reactions, and automating protocols by integrating multiple protocol steps. However, microfluidics fabrication and operation can be expensive and requires expertise, limiting access to the technology. With advances in commodity digital fabrication tools, it is now possible to directly print fluidic devices and supporting hardware. 3D printed micro- and millifluidic devices are inexpensive, easy to make and quick to produce. We demonstrate Golden Gate DNA assembly in 3D-printed fluidics with reaction volumes as small as 490 nL, channel widths as fine as 220 microns, and per unit part costs ranging from $0.61 to $5.71. A 3D-printed syringe pump with an accompanying programmable software interface was designed and fabricated to operate the devices. Quick turnaround and inexpensive materials allowed for rapid exploration of device parameters, demonstrating a manufacturing paradigm for designing and fabricating hardware for synthetic biology.

    Full Text Available Introduction: In orthodontics, apart from essential diagnostic aids, there are so many soft tissue analyses in which lips are major part of concern. However, lip prints have never been used in orthodontics as diagnostic aid or forensic tool. Therefore, this study was designed to explore the possible association of lip prints with skeletal malocclusion. Materials and Methods: A sample of 114 subjects in the age group of 18-30 years, from North Indian adult population were selected on the basis of skeletal class I, class II and class III malocclusion, each comprising of 38 subjects with equal number of males and females. Lip prints of all the individuals were recorded and digital soft copies of lateral cephalograms were taken. Lip prints were compared between different skeletal malocclusions. Results: It was found that branched lip pattern was most common in North Indian adult population with no sexual dimorphism. The Z-test for proportion showed that the prevalence of vertical lip pattern was significantly higher in subjects having skeletal class III malocclusion. Conclusion: A definite co-relation of vertical lip patterns with skeletal class III malocclusion was revealed.

    Full Text Available The objective was to assess the impact of the surface texture of individual creative paper types (coated or patternedon the quality of printing and to identify to what extent the various creative paper types require specific types ofspectrophotometers. We used stereomicroscopic images to illustrate unprinted and printed surfaces of creative papertypes. Surface roughness was measured to obtain data on the unevenness of surfaces. Spectrophotometric tests wereused to select the most suitable spectrophotometer from meters with different illumination setup for testing anygiven print. For the purpose of testing, we used spectrophotometers which are commonly available generally used totest print products for colour accuracy. With the improvement of measuring geometries, illumination setup, colourmeasurement becomes more and more capable of producing reliable results unaffected by surface textures. Our testshave proved this fact by showing that the GretagMacbeth Spectrolino with annular illumination is less sensitive tosurface texture than the X-Rite Spetrodensitometer and the Techkon SpetroDens with directional illumination. Furthertests have brought us to the conclusion that there is a difference even between the two devices with directionalillumination. While the X-Rite 530 Spectrodensitometer is more suitable for testing coated surfaces, the TechkonSpectroDens can come close to ΔE*ab values produced by the annular illuminated device for textured surfaces.

    Full Text Available Information is indispensable factor of any enterprise. It can be a record or a document generated for every transaction that is made, which is either a paper based or in electronic format for future reference. A Printing Industry is one such industry in which managing information of various formats, with latest workflows and technologies, could be a nightmare and a challenge for any operator or an user when each process from the least bit of information to a printed product are always dependendent on each other. Hence the information has to be harmonized artistically in order to avoid production downtime or employees pointing fingers at each other. This paper analyses how the implementation of Electronic Document Management System (EDMS could contribute to the Printing Industry for immediate access to stored documents within and across departments irrespective of geographical boundaries. The paper outlines initially with a brief history, contemporary EDMS system and some illustrated examples with a study done by choosing Library as a pilot area for evaluating EDMS. The paper ends with an imitative proposal that maps several document management based activities for implementation of EDMS for a Printing Industry.

    Foley, Jennifer; Schmid, Heinz; Stutz, Richard; Delamarche, Emmanuel

    2005-11-22

    Microfluidic devices are well suited for the miniaturization of biological assays, in particular when only small volumes of samples and reagents are available, short time to results is desirable, and multiple analytes are to be detected. Microfluidic networks (MFNs), which fill by means of capillary forces, have already been used to detect important biological analytes with high sensitivity and in a combinatorial fashion. These MFNs were coated with Au, onto which a hydrophilic, protein-repellent monolayer of thiolated poly(ethyleneglycol) (HS-PEG) was self-assembled, and the binding sites for analytes were present on a poly(dimethylsiloxane) (PDMS) sealing cover. We report here a set of simple methods to extend previous work on MFNs by integrating binding sites for analytes inside the microstructures of MFNs using microcontact printing (muCP). First, fluorescently labeled antibodies (Abs) were microcontact-printed from stamps onto planar model surfaces such as glass, Si, Si/SiO2, Au, and Au derivatized with HS-PEG to investigate how much candidate materials for MFNs would quench the fluorescence of printed, labeled Abs. Au coated with HS-PEG led to a fluorescence signal that was approximately 65% weaker than that of glass but provided a convenient surface for printing Abs and for rendering the microstructures of the MFNs wettable. Then, proteins were inked from solution onto the surface of PDMS (Sylgard 184) stamps having continuous or discontinuous micropatterns or locally inked onto planar stamps to investigate how the aspect ratio (depth:width) of microstructures and the printing conditions affected the transfer of protein and the accuracy of the resulting patterns. By applying a controlled pressure to the back of the stamp, Abs were accurately microcontact-printed into the recessed regions of MFNs if the aspect ratio of the MFN microstructures was lower than approximately 1:6. Finally, the realization of a simple assay between Abs (used as antigens

    The solution printability of organic semiconductors (OSCs) represents a distinct advantage for materials processing, enabling low-cost, high-throughput, and energy-efficient manufacturing with new form factors that are flexible, stretchable, and transparent. While the electronic performance of OSCs is not comparable to that of crystalline silicon, the solution processability of OSCs allows them to complement silicon by tackling challenging aspects for conventional photolithography, such as large-area electronics manufacturing. Despite this, controlling the highly nonequilibrium morphology evolution during OSC printing remains a challenge, hindering the achievement of high electronic device performance and the elucidation of structure-property relationships. Many elegant morphological control methodologies have been developed in recent years including molecular design and novel processing approaches, but few have utilized fluid flow to control morphology in OSC thin films. In this Account, we discuss flow-directed crystallization as an effective strategy for controlling the crystallization kinetics during printing of small molecule and polymer semiconductors. Introducing the concept of flow-directed crystallization to the field of printed electronics is inspired by recent advances in pharmaceutical manufacturing and flow processing of flexible-chain polymers. Although flow-induced crystallization is well studied in these areas, previous findings may not apply directly to the field of printed electronics where the molecular structures (i.e., rigid π-conjugated backbone decorated with flexible side chains) and the intermolecular interactions (i.e., π-π interactions, quadrupole interactions) of OSCs differ substantially from those of pharmaceuticals or flexible-chain polymers. Another critical difference is the important role of solvent evaporation in open systems, which defines the flow characteristics and determines the crystallization kinetics and pathways. In

    A capacitive acoustic resonator developed by combining three-dimensional (3D) printing and two-dimensional (2D) printed electronics technique is described. During this work, a patterned bottom structure with rigid backplate and cavity is fabricated directly by a 3D printing method, and then a direct write inkjet printing technique has been employed to print a silver conductive layer. A novel approach has been used to fabricate a diaphragm for the acoustic sensor as well, where the conductive layer is inkjet-printed on a pre-stressed thin organic film. After assembly, the resulting structure contains an electrically conductive diaphragm positioned at a distance from a fixed bottom electrode separated by a spacer. Measurements confirm that the transducer acts as capacitor. The deflection of the diaphragm in response to the incident acoustic single was observed by a laser Doppler vibrometer and the corresponding change of capacitance has been calculated, which is then compared with the numerical result. Observation confirms that the device performs as a resonator and provides adequate sensitivity and selectivity at its resonance frequency.

    2007-10-01

    Full Text Available In this study, we attempted to determine the frequency and types of metaphors in a corpus of titles from a single medical journal collected over one year. The frequency of metaphor tokens (4.6% was highest among editorials and other opinion articles and consisted predominantly of primary metaphors, which require explanation using a visual, cultural or other physical vehicle. When the metaphor was used only in the title and not in the body of the text, as was common in letters to the editor or in editorials, the metaphor may constitute a para-textual device used for engaging the reader. Other metaphors among research article titles were present not only in the title, but also used repeatedly in the body of the text. Among these research articles, metaphors were frequently used to endow the focus words of the metaphor with a precise and meaningful significance which, when used repeatedly in the text, may constitute a mechanism by which sub-technical language or internal jargon may arise. Being syntactically simple but endowed with a high communicative import, titles as a text type may help improve academic literacy, among beginners.

    This paper describes 3D-printed titanium compliant mechanisms for aerospace applications. It is meant as a primer to help engineers design compliant, multi-axis, printed parts that exhibit high performance. Topics covered include brief introductions to both compliant mechanism design and 3D printing in titanium, material and geometry considerations for 3D printing, modeling techniques, and case studies of both successful and unsuccessful part geometries. Key findings include recommended flexure geometries, minimum thicknesses, and general design guidelines for compliant printed parts that may not be obvious to the first time designer.

    Full Text Available Aims and Objective: The study aims to develop latent lip prints on glass surface using fingerprint black powder and its comparison with standard lipstick prints and also determines the effectiveness of the technique. Materials and Methods: This study included a total of 100 subjects, comprising of 50 males and 50 females with age ranging from 17 to 38 years. Latent lipprint was developed by pressing the lips against a glass slab with lips together and the print formed was developed by sprinkling the black finger print powder and transferred to a bond sheet. Subsequently, standard lipstick print was developed from the same subject. All the samples were coded and graded according to the patterns suggested in the literature. Results: Out of 100 latent prints only 29 prints showed lip patterns in all four quadrants. The percentage matching with self lipstick print of good latent prints ranged from 25% to 100% and those of random prints ranged from 8% to 92%. Quadrant wise matching ranged from 52.67% to 57.67%. Statistically significant difference was observed between males and females. Conclusion: The study demonstrates the usefulness of latent lip print in personal identification.

    Biometric evidence plays a crucial role in criminal scene analysis. Forensic prints can be extracted from any solid surface such as firearms, doorknobs, carpets and mugs. Prints such as fingerprints, palm prints, footprints and lip-prints can be classified into patent, latent, and three-dimensional plastic prints. Traditionally, law enforcement officers capture these forensic traits using an electronic device or extract them manually, and save the data electronically using special scanners. The reliability and accuracy of the method depends on the ability of the officer or the electronic device to extract and analyze the data. Furthermore, the 2-D acquisition and processing system is laborious and cumbersome. This can lead to the increase in false positive and true negative rates in print matching. In this paper, a method and system to extract forensic prints from any surface, irrespective of its shape, is presented. First, a suitable 3-D camera is used to capture images of the forensic print, and then the 3-D image is processed and unwrapped to obtain 2-D equivalent biometric prints. Computer simulations demonstrate the effectiveness of using 3-D technology for biometric matching of fingerprints, palm prints, and lip-prints. This system can be further extended to other biometric and non-biometric modalities.

    Full Text Available Cell printing is a promising technology in tissue engineering, with which the complex threedimensional tissue constructs can be formed by sequentially printing the cells layer-by-layer. Though some cell printing experiments with commercial ink-jet printer show the possibility of this idea, there is a long way to implement cell printing in engineering. To get a better understanding of drop on demand piezoelectric cell printing, a cell printing experiment system with commercial piezoelectric ink jet printing head and configurable drive circuit is developed. And a series of cell printing experiment with yeast cell is performed to study the influence of drive parameters, cell solution density and viscosity of the solution on cell survival rate, droplet density and orifice status. The experimental results show that the cell solution density and its viscosity are key issue for cell printing with commercial printing head, and a large drive pulse width is helpful for printing the cell solution with a high cell density and viscosit.

    Full Text Available Cornell University Library has made Print-On Demand (POD books available for many of its digitized out-of-copyright books. The printer must be supplied with metadata from the MARC bibliographic record in order to produce book covers. Although the names of authors are present in MARC records, they are given in an inverted order suitable for alphabetical filing rather than the natural order that is desirable for book covers. This article discusses a process for parsing and manipulating the MARC author strings to identify their various component parts and to create natural order strings. In particular, the article focuses on processing non-name information in author strings, such as titles that were commonly used in older works, e.g., baron or earl, and suffixes appended to names, e.g., "of Bolsena." Relevant patterns are identified and a Python script is used to manipulate the author name strings.

    Full Text Available The rights afforded to Indigenous Australians under the Native Title Act 1993 (NTA are very limited and allow for undue coercion by corporate interests, contrary to the claims of many prominent authors in this field. Unlike the Commonwealth’s first land rights law, Aboriginal Lands Rights (Northern Territory Act 1976 (ALRA , the NTA does not offer a right of veto to Aboriginal parties; instead, they have a right to negotiate with developers, which has in practice meant very little leverage in negotiations for native title parties. And unlike ALRA, developers can deal with any Indigenous corporation, rather than land councils. These two factors have encouraged opportunistic conduct by some developers and led to vexatious litigation designed to break the resistance of native title parties, as demonstrated by the experience of Aboriginal corporations in the iron ore-rich Pilbara region of Western Australia.

  7. REAL TIME QUALITY CONTROL OF THE HEATSET OFFSET PRINTING PROCESS

    2016-05-01

    Full Text Available Offset lithography is one of the most common ways of creating printed materials. Compared to other printing methods, offset printing is best suited for economically producing large volumes of high quality prints in a manner that requires little maintenance. Because of the high speed and the high volume of the printing press, we have to rely on automation for press control and not just to the printer’s eye. When printing an image that has more than one color, it is necessary to print each color separately and ensure each color overlaps the others precisely. If this is not done, the finished image will look fuzzy, blurred or "out of register". To help line the colors up correctly, a system of registration is necessary. Therefore, the use of an automated real time quality control system will result in a more consistent color for the customer and less waste for the printer.

    The cost and scope of additive printing machines range from several hundred to hundreds of thousands of dollars. For the extra money, one can get improvements in build size, selection of material properties, resolution, and consistency. However, temperature control during build and fusing predicts outcome and protects the IP by large high cost machines. Support material options determine geometries that can be accomplished which drives cost and complexity of printing heads. Historically, 3D printers have been used for design and prototyping efforts. Recent advances and cost reduction sparked new interest in developing printed products and consumables such as NASA who is printing food, printing consumer parts (e.g. cell phone cases, novelty toys), making tools and fixtures in manufacturing, and recursively print a self-similar printer (c.f. makerbot). There is a near term promise of the capability to print on demand products at the home or office... directly from the printer to use.

    Full Text Available 3D printing, one of the hottest cutting-edge interdisciplinary technologies, is projected to have revenue of $8.4 billion in 2020. #D printing technology will implement the concept of personalized medicine in medical healthcare industry and pharmaceutical fabrication. Organ printing, which it is defined as computer-aided, jet based 3D tissue-engineering of living human organs, is an interesting and challengeable field for 3D printing. Customized implants and prostheses can be produced in any imaginable geometry through the translation of radiological images of patients into digital.stl 3D print files. The creation of anatomical models based on the patient’s pathological conditions using 3D printing technologies would provide good models for training and to design surgical approaches. Hence, 3D printing not only will transform medical healthcare industry but also promises new converging technologies in the field of regenerative medicine.

    A novel 3D printing procedure is presented for fabricating carbon-nanotubes (CNTs)-based microsupercapacitors. The 3D printer uses a CNTs ink slurry with a moderate solid content and prints a stream of continuous droplets. Appropriate control of a heated base is applied to facilitate the solvent removal and adhesion between printed layers and to improve the structure integrity without structure delamination or distortion upon drying. The 3D-printed electrodes for microsupercapacitors are characterized by SEM, laser scanning confocal microscope, and step profiler. Effect of process parameters on 3D printing is also studied. The final solid-state microsupercapacitors are assembled with the printed multilayer CNTs structures and poly(vinyl alcohol)-H3PO4 gel as the interdigitated microelectrodes and electrolyte. The electrochemical performance of 3D printed microsupercapacitors is also tested, showing a significant areal capacitance and excellent cycle stability.

    The article provides a comparison of the main valuation techniques for a regulated parameter of printability of the offset paper by current standards GOST 24356 and ISO 3783: 2006. The results of development and implementation of a complex test scale for management and control the quality of printed production are represented. The estimation scale is introduced. It includes normalized parameters of print optical density, print uniformity, picking out speed, the value of dot gain, print contrast with the added criteria of minimizing microtexts, a paper slip, resolution threshold and effusing ability of paper surface. The results of analysis allow directionally form surface properties of the substrate to facilitate achieving the required quality of the printed image parameters, i. e. optical density of a print at a predetermined level not less than 1.3, the print uniformity with minimal deviation of dot gain about the order of 10 per cents.

    There currently lacks of a way to directly write out electronics, just like printing pictures on paper by an office printer. Here we show a desktop printing of flexible circuits on paper via developing liquid metal ink and related working mechanisms. Through modifying adhesion of the ink, overcoming its high surface tension by dispensing machine and designing a brush like porous pinhead for printing alloy and identifying matched substrate materials among different papers, the slightly oxidized alloy ink was demonstrated to be flexibly printed on coated paper, which could compose various functional electronics and the concept of Printed-Circuits-on-Paper was thus presented. Further, RTV silicone rubber was adopted as isolating inks and packaging material to guarantee the functional stability of the circuit, which suggests an approach for printing 3D hybrid electro-mechanical device. The present work paved the way for a low cost and easygoing method in directly printing paper electronics.

    Movie is a popular art which occupies an important position in people’s leisure time. Movie title, as the most direct and accessible tool for audience to know about the movie, is very significant to attract audience into the cinema. Therefore, the translation of movie title cannot be ignored. However, due to the cultural differences in Chinese and English culture, the problem of movie title translation is obvious which needs to be paid attention to the translation and people working in movie industry. Traditional translation theory puts more emphasis on the important and authoritative status of original text and author. But this notion cannot satisfy the needs of movie title translation to the largest extent. Movie is not only a cultural and linguistic product, it also is a special commercial product. The ultimate objective of movie is to allure the audience into the cinema to watch and ap-preciate it in addition to provide the cultural information. Reception aesthetics, as a theory of literary criticism, gives priority to readers’role in literary understanding and interpretation. According to reception aesthetics, the horizon of expectation should be taken into consideration when the translation work begins to be done. Horizon of expectation is composed of the readers’or au-diences’ previous cultural norms, assumptions, and criteria in the source language and culture at a given time. Movie title, as a special text, is also understood and influenced by the audience’s horizon of expectation. Chinese audience, before they decide to watch a movie, are naturally harbor their horizon of expectation about the movie. They will form their judgment and assumptions about the genre, plot, story, background about the movie from the movie title. These kind of horizon of expectation will conse-quently influence their ultimate decision to watch the movie or not. Hence, in doing the movie title translation, the translator is supposed to keep the audience’s horizon of

    2012-04-01

    Titles of journal articles serve to attract attention and inform potential readers. All titles from 65 volumes of American Psychologist (1946-2010, N = 12,313 titles) were studied in terms of their emotionality, style, and contents. Several trends noted for titles in different kinds of journals from psychology and other disciplines were present in American Psychologist (increasing title length, increasing use of punctuation marks, increasing employment of words with pleasant and arousing connotations, variations in the frequency of different content words). Longer titles allow authors to specify more information, and emotionally upbeat titles are more likely to attract reader attention. In an unexpected quadratic trend, titles became more abstract and the number of titles increased until about 1985, after which the trend was reversed and titles became more concrete as their numbers decreased. Predictors of this trend include societal variables and the journal's editorial policies.

    Full Text Available Electrophotographic printing uses many types of substrates, our study focuses on plastic substrates. Six types ofregular and self-adhesive foil substrates were chosen to be printed using two electrophotographic presses: XeroxColour 1000 Press and Canon imagePress C7000VP. A test chart containing tone value scales and a set of samplesfor profiling was created, spectrophotomety and densitometry was applied to obtain the optical and colorimetricproperties of the substrates investigated. Xerox Color 1000 Press produced larger densities and tone value increaseon every type of substrate. The largest TVI values and reproducible colour gamut was observed on the smoothestfoil in case of both presses. Large colour differences were found between patches of full tone process colors on thedifferent substrates investigated.

    Changing demands in advertising and printing business has made the digital press systems valid competitors to offset technology for specific markets. Whereas offset is still superior in quality and high volume printing, the time consuming and costly prepress activities, as well as the need for huge investments in the press, make the all-in-one formula very attractive. How to link a fast/cheap machine with decent output-quality, making use of electrophotography? We use electrophotography as a pretext for making a stability analysis of several halftoning systems. As shown in a previous article (Ref. 3) we use the Fourier characteristics to figure out its dependence. In a first introduction we point out why electrophotography brings us to this matter. The further outline of the article scans through a list of opposite screening systems where we focus on the color stability in function of registration.

    Magnetic resonance imaging is an inherently signal-to-noise-starved technique that limits the spatial resolution, diagnostic image quality and results in typically long acquisition times that are prone to motion artefacts. This limitation is exacerbated when receive coils have poor fit due to lack of flexibility or need for padding for patient comfort. Here, we report a new approach that uses printing for fabricating receive coils. Our approach enables highly flexible, extremely lightweight conforming devices. We show that these devices exhibit similar to higher signal-to-noise ratio than conventional ones, in clinical scenarios when coils could be displaced more than 18 mm away from the body. In addition, we provide detailed material properties and components performance analysis. Prototype arrays are incorporated within infant blankets for in vivo studies. This work presents the first fully functional, printed coils for 1.5- and 3-T clinical scanners.
