摘　　要：在彩色印刷过程中,通常加印黑版用以补偿印刷图像暗调不足。提出了一种基于纽介堡方程的黑版生成方法,选择IT8.7/3中的部分色块为样本,通过纽介堡方程将样品的XYZ值进行转换,得到了相应的CMY网点面积率。利用黑版计算公式,确定了相关参数的取值,最后得到了黑版值。试验结果表明,该黑版生成方法具有一定的可靠性和实用性,对印刷分色和黑版生成具有参考价值和理论意义。In color printing process,a black plate was added to compensate dark shortage of printing image in general.A black plate generation method based on Neugebauer Equation was proposed.Part of color blocks of IT8.7/3 were selected as the sample,and the XYZ values of the sample were transformed into corresponding CMY dot area rate through Neugebauer Equation.Value of relevant parameters was determined to get the black plate value by using the calculation formula of black plate.The experiment results showed that the black plate generation method has certain reliability and practicability,which has reference value and theoretical significance for color separation in printing and black plate generation.
