摘 要：現代印刷工業的彩色化正在趨于完善，色彩直接決定了印刷品質量，是印刷品質量的基礎，因而建立正確的色彩評價體系極為重要。色彩評價僅僅依靠主觀的視覺評判遠遠不能滿足日益發展的高品質印刷要求，所以必須結合客觀的色彩測量。色彩測量是一種客觀而科學地、定量地描述色彩的原理及方法，它通過儀器代替人的視覺系統“感知”光線從印刷品表面反射出來的光量，并通過一定的運算形成一個客觀的數量描述。
 本文論述了彩色印刷品的主觀評價和客觀評價中的各要素，具體對樣品不同顏色不同網點覆蓋率色塊進行密度測量和色度測量，并對其測量結果進行了分析。
關鍵詞：主觀評價；密度測量；色差；印刷質量

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.
