Abstract

A method of compensating for a defective inkjet in an inkjet printer has been developed. A controller identifies pixels in binary image data corresponding to the defective inkjet. The controller identifies alternative pixel locations for non-defective inkjets to print ink drops proximate to the locations of the defective pixels. When a total overlap parameter value identified in a region of image data around the pixels from the defective inkjet exceeds a predetermined value, the controller changes the alternative pixel location for at least one ink drop to reduce overlap and improve image quality.
