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...

The 3D printing is a combination of digital technology, material science, intelligent manufacturing and control of opto-mechatronics systems. It is called the third industrial revolution from the view of the Economist Journal. A color 3D printing machine may provide the necessary support for high value-added industrial and commercial design, architectural design, personal boutique, and 3D artis...

3D printing is becoming increasingly popular around the world today. By utilizing 3D printing technology, customized products can be manufactured much more quickly and efficiently with much less cost. However, 3D printing still suffers from low quality surface reproduction compared with 2D printing. One effective approach to improve it is to develop an advanced halftoning algorithm for 3D print...

Current color-printing technologies may use three or more inks, e.g., CMY, CMYK, CMYKcm, CMYKGO, CMYKRGB. When the number of inks exceeds three, there is the usual color-management one-to-many mapping problem. Because the spectral properties of many modern inks are optimized for maximum color gamut and in some cases, black ink may not be used for pictorial images, many prints have poor color co...

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...

Color reproduction stabilization is a control process to ensure that the printed output matches the desired color tones. In this paper we consider the stabilization of single color tone separation. The mapping of input-tone to output-color is characterized by the color tone reproduction curve(TRC). By compensating for any variations of the Xerographic printing process, the TRC stabilization con...

Structural coloring is production of color by surfaces that have microstructure fine enough to interfere with visible light; this phenomenon provides a novel paradigm for color printing. Plasmonic color is an emergent property of the interaction between light and metallic surfaces. This phenomenon can surpass the diffraction limit and achieve near unlimited lifetime. We categorize plasmonic col...
