Abstract
A quality control method for printed products at a control console includes recording image information of the printed product with a camera device, comparing the recorded data to digital image data of the printed image in a computer, displaying a digital version of the printed product on a screen associated with the control console and illuminating the printed product with at least one light source. The printed product is sensed by using at least one sensor, the position of the printed product relative to the light source and/or relative to the angle of vision of a person is calculated by using a computer, and the displayed digitized version of the printed product is displayed on the screen in accordance with or corresponding to the position of the real printed product.
