摘 要：现代印刷工业的彩色化正在趋于完善，色彩直接决定了印刷品质量，是印刷品质量的基础，因而建立正确的色彩评价体系极为重要。色彩评价仅仅依靠主观的视觉评判远远不能满足日益发展的高品质印刷要求，所以必须结合客观的色彩测量。色彩测量是一种客观而科学地、定量地描述色彩的原理及方法，它通过仪器代替人的视觉系统“感知”光线从印刷品表面反射出来的光量，并通过一定的运算形成一个客观的数量描述。
 本文论述了彩色印刷品的主观评价和客观评价中的各要素，具体对样品不同颜色不同网点覆盖率色块进行密度测量和色度测量，并对其测量结果进行了分析。
关键词：主观评价；密度测量；色差；印刷质量

Abstract:The modern color priting industry is perfecting,of which decide directly to the print quality and is the basis factors of quality.Therefore,building a right eva luation system is very important.The color measurement relying solely on subjective visual judge cannot satisfy the incessant growth of high quality requirements,so it must be combined with the objective of the survey.The measurement is an objective and science and quantitatively described the principles and methods,instrumenting in place by the visual system perception light from the printed surface of reflections of light,and must have the operation of an objective description.
 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.
