Method for operating a processing device integrated in a web-fed printing press

摘要

The method involves automatically measuring a web substrate (14) by a sensor (22) attached to a processing unit i.e. inkjet printing unit (17) of a web-fed press. A transverse offset is automatically determined for the processing unit according to the measurement of the substrate to position a print image transverse to a transporting direction of the substrate, where the print image is to be printed by the processing unit. A control signal is determined for the processing unit based on measurement of the substrate to position the print image in the transporting direction of the substrate.
