Subjective assessment of printed color image quality as saturation of the primary colors RGB decreases

摘要

The image quality cannot be easily applied to a color management system because the quality cannot be quantified by objective methods in general. In this paper, two subjective experiments are performed to quantify the relation between the printed image quality and the color-change of the images. In these experiments, observers are requested to estimate the color-changed images that are caused by the saturation decrease of three primary colors. The results of the experiment show that decreasing color saturation of the primary colors affects the quality of printed images. In addition, the decreasing saturation of B on image quality is significantly larger than the effects of decreasing saturation of other primary colors.
