Abstract
Systems and methods selectively remove flush drops from a plurality of ink drops ejected by a print engine when printing data for a print job. One embodiment comprises a control system of a printing system. The control system receives a flush pattern for flushing an ink jet print engine of the printing system, and receives a sheetside bitmap for printing to a print medium. The control system merges the flush pattern and the sheetside bitmap to generate a composite sheetside bitmap. The control system directs the print engine to eject a plurality of ink drops toward the print medium based on the composite sheetside bitmap, and identifies a subset of the ink drops based on the flush pattern. The control system then directs a drop deflection system of the printing system to selectively prevent the subset of ink drops from impinging the print medium.
