关于灰平衡数据的计算

The Calculation of Gray Balance

灰平衡数据是彩色图像复制中色彩变化的依据,文中应用灰平衡方程作为理论基础,通过测量四色各级网点密度,求取灰平衡数据,并利用n值进行修正网点面积,再利用打样来检验所得数据的可行性,以保证图像色彩得到正确还原。

The data from the grey balance is the basis of the color image duplication. According to the grey balance equation, the data of the grey balance is got by measuring all the dot density and calculating. It can be used to correct the dot area with the value 'n' and check with the specimen and to guide the color image duplication.
