This article briefly discusses the different elements of the subjective eva luation and the objective eva luation in the color printing, and Specificly measures percentage of the sample in different blocks of color measurement and color measurement of density,of which measurement results were analyzed. Keywords:Subjective eva luation;Density measurement;Printing chromaticity;print- ing quality
