System for automatic quality inspection of a printed image, comprising an image sensor, evaluation unit and display
Abstract:
A system is provided for inspecting a printed image. The system is provided with at least one evaluation unit, a display device and an image scanner. That scanner takes an image that represents, at least partially, a printed image. The copied printed image belongs to a sequence of images printed on a print carrier by a printing machine. The evaluation unit receives data that is correlated to an image which has been taken, and evaluates that data by comparing it with recorded data of at least one preceding image, or with a reference image. The display device is provided with a graphic display surface that is comprised of several areas which are controlled, in a different manner, by the evaluation unit, and which are preferably simultaneously displayed. A first area displays several images, such as the just taken image, the preceding image and the reference image. The second area includes an input field or a control point for adjusting or controlling the evaluation unit or for adjusting or controlling the printing machine.
