A densitometer or a scanner is used to measure the control strip that provides color control. These measurements are used to instruct the printer to give more ink or lesser ink at some zones in printing area. There’s a high requirement of print matching to match the original or the fixed system data, precision in a must in this situation. The analysis of sample prints is done against the original data. Further fine-tuning the ink results in closer and closer print results to the original color model. For optimal prints or reprints, all the settings can be saved in any integrated software or in computer tapes. Once the matching is complete and we can be certain about the registration of color perfectly then the real print process begins. However, not taking any chances, the press operator continually takes sample prints in order to ensure consistent color scheme and monitor it as well.
