Reliable and precise print mark detection

Print marks help to position print sheets correctly in automated production processes. Thanks to dynamic threshold adaptation, the KTS Prime contrast sensor can reliably and nevertheless quickly detect even faded print marks. Being a smart sensor, it can be configured via IO-Link. This enables further operations, such as perforation or folding of the print sheets, to be initiated at the correct location in the work process. The OMR (Optical Mark Recognition) codes are used to control table top inserters.
