Optimization of Technical Parameters on the Color Variation in offset Printing Process

Abstract

In this study, the optimization of parameters of the printing process was carried out. The aim is to minimize the size of color variation in prints. A factorial design was used to evaluate the effects and interactions of three factors, that is, impression pressure, alcohol %, and press speed. The color variation is gauged by variation in ink transfer, which is governed by color difference (?E). The optimal conditions obtained from the desirable response are impression pressure of 0.15 mm, alcohol percentage of 12.2 % and press speed of 8500 sheets per hour. Under these conditions, about 0.62 of color difference is obtained.
