Supplemental data processing system for processing ply-matching data generated during multiple-part product printing

摘要

A data processing system is provided which can be connected to an existing ply matching and verification system for multiple-part printed products to perform a number of additional operations external to the matching and verification system. The data processing system is configured to access the data stream generated by the matching and verification system at two data points corresponding, respectively, to after indicia on a ply is detected and before it is stored for matching purposes, and after the indicia on all of the plies of a printed product has been stored in a buffer.
