This paper takes a look at issues arising in color printing, such as color models, color conversion and color separation. Increasingly, it is feasible to perform these functions on existing PostScript files, independent of the authoring software. The pdf format plays a key role in this trend. keywords Color printing, color model, device-independent color, color conversion, color separation, pdf...

background: according to the growth of photocopier usage in workplaces, the potential risk of occupational exposure to the airborne chemicals has been raised up. hence, monitoring the photocopy worker's respiratory functions seems to be necessary. we aimed to evaluate the respiratory health on photocopy and printing workers so that a reliable description can be made about their occupational hyg...

Controlling the occurrence of defects is a major challenge for manufacturing organizations that are seeking to enhance their competitive position in today’s global market. This paper considers the process of screen-printing T-shirts using hydraulic and pneumatic printing machines. Several defects in the output of this printing process have been observed, especially with multi colors printing as...

The advent of 3D printers has been embraced globally within few years of its emergence. The surge in the acceptability of rapid manufacturing RM technology can be attributed to the depletion and cost of natural resources, waste reduction and sustainability criterion of manufactured parts. This rapidly evolving 3D printing technologies is predicted to grow exponentially especially for the manufa...

The web has moved from a minority interest tool to one of the most heavily used platforms for publication. Despite originally being designed by and for academics, it has left academic publishing largely untouched; most papers are available on-line, but in PDF and are most easily read once printed. Here, we describe our experiments with using commodity web technology to replace the existing publ...

Using Computational Fluid Dynamics (CFD) technique, the dispersion contours and the exposure rate of Flexographic printing workers to VOCs in a printing department is evaluated. Firstly, VOCs distribution is determined in the printing room due to the existing ventilation system. Through next steps, 4 scenarios for lowering VOCs concentration and its exposure rate to workers are analyzed. Concen...

he prevailing methods for publishing scientific research results are inefficient, slow and expensive. It usually takes between one to two years from the original submission of a manuscript to its final printing in an issue of a peer-reviewed journal. In addition publication as such is no guarantee that the information reaches its target readership. Fortunately recent developments in IT and comp...

The traditional way of publishing books is a one-dimensional procedure. An author creates content, believing that somebody may be interested in it. A publisher invests money in his book project, financing the production, the marketing and the distribution to the bookstores. The readers select the books in the bookstore under a wide range of decision criteria’s. At the end of the chain, the publ...

Introduction Scholarly communication in the social sciences is centered around publications, in which data also play a key role. The increasingly collaborative scientific process, from a project plan, to collecting data, to interpreting them in a paper and submitting it for peer review, to publishing an article, to, finally, its consumption by readers, is insufficiently supported by contemporar...
