Abstract: Psychophysics experiment has been carried out in which color appearance of high-gloss and low-gloss printing atlas was assessed by using binocular viewing and matching method under three different light sources. A linearity fitting algorithm by methods of least squares was applied to evaluate the correlation between visual experiment data and predicted results through CIECAM02 model for high-gloss and low-gloss printing atlas. The research result has shown that there is a good correlation between visual experiment data and predicted results for high-gloss and low-gloss printing atlas. The correlation of hue and lightness between visual experiment data and predicted results is the best and the second best, respectively, under the same light source. Colorfulness is the worst. The predicted accuracy of CIECAM02 model for high-gloss printing atlas is better than that of low-gloss printing atlas under the same light source.
