印刷过程中灰平衡数据的计算

Figure Calculation of Gray Balance in Printing Process

分析了印刷灰平衡数据计算中误差产生的原因,并提出了采用牛顿迭代法对纽介堡方程计算中的网点扩大量进行修正.实验数据表明,本方法可以明显提高灰平衡数据计算结果的准确度.

This paper analyzed the cause of errors of figure calculation of gray balance in printing process,and made use of Newton＇s method to correct the Neugebauer equation＇ error by means of dot gain value.Experimental and calculation show that the method can improve the precision of figure calculation.
