In the previous study, the author showed that it is difficult to obtain the optimum combination of color dyes satisfying both spectral and colorimetric color reproduction. The current ink jet printers have solved this problem by a multi-color ink jet system. However, the system above makes color separation process converting RGB to CMYK complicated. The purpose of this study is to reveal the characteristics of the optimum color dyes for spectral and colorimetric color reproduction by means of a computer simulation, and it gives direction in order to design subtractive color dyes. In this paper, spectral RMS error and the size of the color gamut were calculated between the optimum dye sets for spectral and colorimetric color reproduction. Then, the relationship between spectral RMS error and the size of color gamut was evaluated by the peak wavelengths and widths of absorption bands composing the optimum three dyes for colorimetric color reproduction. The result above shows that it is an effective way to make an absorption band at long wavelength broader for satisfying both spectral and colorimetric color reproduction.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
