A Mathematical Model for Printing Color Reproduction Based on Undiscrimination Dot Gain Nature

A MATHEMATICAL MODEL FOR PRINTING COLOR REPRODUCTION BASED ON UNDISCRIMINATION DOT GAIN NATURE You Xiong Zhengzhou Institute of Surveying and Mapping LongHai West Rd. Zhengzhou, Henan 450052 P.R.China This paper analyzes two kinds of dot gain in detail and develops a mathematical model for printing color reproduction based on undiscrimination dot \lain nature. The experiment shows that the mode...

Uv Printing

UV printing is different from conventional printing in many ways. It is still ink on paper but the ink dries through a completely different process. Instead of having solvents in the ink that evaporate into the air and absorb into the paper, UV inks dry through a photomechanical process. When the inks are exposed to ultraviolet lights they turn from a liquid, or paste, to a solid. There is sign...

Printing Insecurity? The Security Implications of 3D-Printing of Weapons

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 an...

Wave Printing (II) : Polymer MISFETs Using Microcontact Printing

The advent of printing for the manufacturing of transistors is a task vividly pursued both for silicon[1] and polymer-based devices [2-4]. Printed MISFET devices based on semiconducting polymer have already been realized with soft lithography [5], but they were either using an unstructured gate substrate or designed for low resolution alignments [2,4]. For printable electronics to become a real...
