摘　　要：为了寻求纽介堡方程产生较大应用误差的本质根源,以其理论基础和目前流行的印前处理方法为依据,采用数学推理和模拟分析相结合的方法,揭示了其固有理论缺陷。结果显示:纽介堡方程在分色定量计算时无法进行正确的数学求解;其叠印关系(包括网点形态和分布)假设缺乏实际支持,难以避免计算误差。In order to find the root of the application error caused by Neugebauer equation,in this paper,the inherent theory flaw of Neugebauer equation is revealed by the combination of mathematical derivation with simulation analysis based on its theoretical basis and popular treatment methods in pre-press.The result shows that it is impossible to solve the problems by Neugebauer equation in mathematics properly on quantitative calculating of color separation,and the calculation errors can not be avoided by the absence of practical support of the superimposition relation assumption（including dot shape and distribution）.
