ABSTRACT:
Exemplary embodiments of the invention include systems and methods of reducing visible print defects in drum printers having multi-die printheads 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.
