Abstract
The printing quality monitoring system is a new inline high-speed inspection equipment for the checking of printing defects (scumming, hickey, mis-resistering, etc.) aiming to replace conventional manual operation. The system is composed of a CCD camera that takes the print pattern as image data, a xenon light source with optical fiber to the printed matter, an image data processing device for judging defects, and a display unit. This system includes the following features: (1) Complete surface inspection of all products. (2) High-speed inspection. (3) High-precision inspection.
