Abstract
The Color Control System (CCS) is in-line color control system for offset web printing processes. It uses color measurement information to increase the accuracy of color reproduction during the printing process. The CCS automatically searches for, locates, and tracks micro color bars to relate color density information to press operators. It also automatically sends any necessary correction to press ink key control console. The measurement for correction is performed by the patented video densitometer installed in the CCS Scanner on the Scanner Stand at the end of printing process. The CCS has capability to eliminate the subjectivity and inconsistency for color reproduction and to maintain the color densities through the press run. The CCS also provides the functions to monitor the 3-color gray balance, CMY midtone balance, trapping and effect of dot gain. This paper reports color control is quickly becoming both an acceptable technology and to meet customer expectations.
