摘　　要：在彩色印刷中,影响印刷呈色效果的因素很多,色序就是其中之一。本研究采用数字印刷系统,利用相同的3色分色原稿,进行了不同色序的印刷实验,基于密度学体系进行了样张数据的测量和分析。研究结果证明不同的印刷色序会产生不同的呈色效果;从密度学体系来看,“首层反射”是反射密度的重要组成部分;“密度的可加性与比例性”命题需要商榷;色序具有分色依赖性。In color printing,there are many factors that affect color reproduction effect,and color sequence is one of them.Based on the digital printing system,the printing experiments with different color sequences for the same three-color separation manuscript were carried out,and the densitometry system was used to measure and analyze the sample data.The research results showed that different color sequences will produce different color reproduction effects.Therefore,the role of the first layer reflection in the reflection density measurement is essential,the additivity and proportionality of density is doubtful,the color order dependence of color separation is also revealed.
