Abstract
A Color Register Control system used to maintain close registration between colors printed on a surface by various printing cylinders. The control system acquires an image of a cluster of register marks printed by various printing cylinders. The register mark is a geometrically unique mark, The mark cluster is acquired by the camera and each mark pattern is identified by checking shape of individual marks. Resulting location of a mark is used to compute and correct registration errors. The image is analyzed to identify marks printed by various printing cylinders. Register error is determined by computing the lateral and circumferential distance between marks printed by a print cylinder and a master print cylinder. Any error detected in this process is corrected by activating correction motors typically stepper motors, on print cylinders. The control utilizes a commercially available IBM-PC compatible computer, which can accept additional boards in the expansion slots for indicated purposes.
