Abstract
In a method and a device for the detection, at the correct time, of pressure marks situated at regular intervals on a print web, use is made of cameras, with a processing unit which is assigned to the camera. The activation of the camera is no longer triggered externally in order to detect the pressure marks. Instead, the drive control system, which actuates a movement of the print web, is connected to a bus to which the cameras and therefore the processing units are also connected. It is thereby possible for the drive control system to provide the processing units with process data which the processing units can use to calculate detection times. The activation of the camera takes place, on the basis of the calculation, automatically by means of the cameras with the processing unit itself.
