摘要
纽介堡方程揭示了印刷网目调颜色形成的物理基础和颜色感觉形成的基本逻辑。本研究在不考虑工艺因素情况下,基于纽介堡方程,从理论和仿真分析两方面揭示了加网误差的客观必然性:通过网点微观形态的解析,从理论上指出了分色与加网的相关性;借助于纽介堡方程的仿真分析与色元网点面积率计算,展示了不同数字加网方法之间的理论色差。
Neugebauer Equation reveals the physical basis of the formation of the halftone printing color and the basic logic of the formation of the color perception.In this paper,based on Neugebauer Equation,the objective necessity of screening error was revealed from both theoretical and simulation analysis,in the case without considering the process factors.Through the analysis of the screen dot morphology,it pointed out the relativity of color separation and screening in theory.The theoretical color difference of the different digital screening methods was worked out through Neugebauer Equation simulation analysis and the calculation of color perarea ratio statistics.
