Abstract
The control process according to the invention is usable with high performance production processes for producing printed products by collecting, inserting and/or collating, e.g. with the aid of a drum (10). It comprises recording an image of the products being formed following each addition of a further component with a camera (K), comparison of the recorded image with a corresponding, stored calibration image, and using the results of the comparison for generating control signals, e.g. for discharging faulty products or activating alarm means. Instead of stationary image recording means such as cameras, movable reading heads can be used in the inventive process also.
