Increasing number of imaging systems and devices recently support various kind of wide gamut color spaces such as Adobe RGB color space. Adobe RGB 1998 is generally used to produce more vivid colors in digital photography. Various gamut mapping techniques has been developed by many researchers to enhance printer colors. However, little literature has focused on the study of printer color mapping for a wide gamut source space. In this paper we propose a novel experimental methodology of print color correction for the wide gamut input. We compare gamut boundaries and primaries of the reference gamut sRGB and the wide gamut Adobe RGB, and then extract key factors for print color correction. While we employ a gamut mapping method from the reference gamut to the printer gamut, we transform input colors by controlling global lightness, shifting hues, and performing saturation enhancement. Based on psychophysical experiments, we find optimal values of correction factors. We apply our method in two different printers: an electrophotographic laser printer and a dye sublimation photo printer. Comparison test results show the higher preference scores in both cases. This suggests that for a given wide gamut input we can substantially match print colors with the source.

  • 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.
