摘要： A system and processes for the accurate measurement and control of image color values on a printing press with or without the presence of a color bar. More particularly, a barless color control system and processes for controlling the color quality of color images printed on a substrate online or offline, with or without a color bar printed on the substrate. The system provides an efficient and inexpensive method for barless closed loop color control and the processes are conducted without pixel-by-pixel comparisons.

摘要： A system for the accurate measurement and control of image color density on an operating printing press. The method and apparatus control the printing of a multicolored image by controlling the amount of each of the inks used to print an image based on the color densities of each of the inks detected in printed images. The process includes controlling the positioning and linear movement of a strobe and a digital video camera across a substrate having images printed thereon; illuminating the images with a strobe; selecting and acquiring the images via a digital video camera and producing a digitized representation thereof; selecting a portion of the images; measuring and analyzing the color intensity of the selected portion of the images and producing reflective density values thereof, and storing said reflective density values in a first memory; comparing the reflective density values for the portion of the images to standard density values in a second memory for the portion of the images.
