ABSTRACT:
A quality control system for a printing plant adapted to efficiently and accurately correlate information needed for printing quality control, which information had required at least an element of human mental correlation in the past. A printing console has a video camera aimed at a printed sheet on the console, a light source having a position related to that of the video camera, measuring devices such as scanners for measuring particular areas of the printed sheet, and control keys for zonal press controls such as control of zonal ink supply. A processor is associated with an image memory adapted to create an electronic image of the printed sheet on the table. The processor also has access to a reference memory in which is stored a further representation of the image along with coordinates for quality control zones. The processor correlates the image created by the video camera with the reference image in order to associate the quality control zones from the reference image with the actual sample on the table. The processor then operates a display device with respect to the actual sample on the table.
