Flexo Four-color Printing, Coloring The Mathematical Model

This paper mainly discusses the problem of how to establish four-color mathematical model of Flexography.At the beginning of this paper, the characteristic of flexography and the situation of experiment made for establishing the mathematical model are introduced briefly. Afterthat I analyze the characteristic of flexography in detail. At last the mathematical model of Flexography is established according to Neugebauer Equations. According to the Equations, the coefficients of regression equation are calculated, then based on analyzing chromatic aberration of the model, I modify that model and evaluate its precision.The primary attempt and probing are part of our task-A Study on the Mathematical Model of Flexographic Color Reproduction (Special Scientific Research Program Funded by Shaanxi Provincial Education Commission, Program No. 99JK197), which lays a theoretical base and accumulates the practice experience for the further study in the future.
