SYSTEM AND METHOD TO HIDE DIE-TO-DIE BOUNDARY BANDING DEFECTS IN A DRUM PRINTER

摘要

Disclose are systems and methods of reducing visible print defects in drum printers 100, 300 having multi-die printheads 242, 244, 342, 344, 442 oriented substantially perpendicular to the print media path. The exemplary embodiments include printing very small amounts of additional ink via empirically determined printing masks in addition to the normal image content, such that the print defects become less visible. Further exemplary embodiments include printing the additional ink during times typically utilized for print drying.
