Abstract
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.
