Flush line generation in printing systems that utilize control marks

摘要

Systems and methods are provided for generating flush lines that do not interfere with control marks for post-processing equipment. The system includes a print controller able to receive a print job and to insert printable control marks into the print job to direct the actions of post-processing equipment. The system also includes an ink flushing controller that can detect horizontal locations of the control marks along the width of the print job. Responsive to detecting the locations of the control marks, the ink flushing controller can generate flush lines for the print job that have altered optical densities at the horizontal locations.

1. A system comprising:
a print controller operable to receive a print job and to insert printable control marks into the print job that direct the actions of post-processing equipment handling the print job; and an ink flushing controller operable to detect horizontal locations of the control marks along the width of the print job, and responsive to detecting the locations of the control marks, to generate flush lines for the print job that have altered optical densities at the horizontal locations, thereby preventing visual conflicts between the flush lines and the control marks that would cause the flush lines to be interpreted as control marks.
