Abstract
An imprinting system of the type including: a conveyer; a plurality of feeders for delivering signatures to a conveyer, the conveyer moving the signatures in a predetermined direction along a conveyer path; a printer disposed proximate to the conveyer along the path for imprinting on portions of signatures within a predetermined print field; improved in that the system further comprises: a scanner for scanning a field of view disposed along the path extending in the predetermined direction in predetermined relation to the print field and generating scanner output signals indicative of the position of the signature within the field of view; and the system for controlling the printer includes varying the position of the print field relative to the field of view in accordance with the movement of the signatures through the field of view.
