ABSTRACT:
A control system is disclosed for controlling misregistration between the colors of an image printed on a web. The system includes an imaging device such as a camera or group of cameras, a processor, and image conversion circuits coupled to the processor. The system detects print color misregistration based upon the signals produced by the imaging device as a result of scanning the printed image. The conversation circuits convert the signals to signals usable by the processor to determine the color densities of the various colors within the image. These color densities are compared with reference color densities stored in a memory of the processor, where the reference color densities may be generated from a source such as the printing plates used to print the image for which misregistration is being monitored. Based upon the comparison of the color densities derived as a result of scanning the printed web, and the reference color densities, a processor operates to produce registration offset values between the printed colors which are used to control a print controller which controls the print units such that the colors of the printed image are placed into registration.
