Printer for printing a plurality of images on a substrate web

摘要

The printer comprises: a digital printing station (12); a support (20) for a roll (22) of the substrate web (24) carrying a plurality of synchronisation marks; means (28) for continuosly feeding the substrate web (24) from the roll (22) past the printing station (12); a sensing device (32) positioned upstream of the printing station (12) for sensing the synchronisation marks on the web (24); and control means (38) for initiating a printing sequence at the printing station (12) in response to the sensing of each of the synchronisation marks (26, 34, 36). Thereby a plurality of images are printed on the web (24), each at a predetermined location in the transport direction relative to an associated one of the synchronisation marks (26, 34, 36). <IMAGE>
