ABSTRACT:
Multi-station web handling apparatus having a pair of nip rolls at each station, where at least one of the rolls of each pair of nip rolls is deformed at the nip and having a print-to-print and/or cut-to-print image registration system and method that prevents image mis-register errors from occurring, as opposed to attempting to correct mis-register errors after they have occurred and have been sensed. Each of the stations includes a driven nip roll positioned upstream of and closely adjacent to the nip of the pair of nip rolls of the station. The rolls are driven at the same speed as the pairs of nip rolls at the stations are driven.
