ABSTRACT:
The invention provides an apparatus and method for printing an image using the printhead of an ink jet printer. The printhead ejects ink drops on a print medium in a series of scanning passes, and different addressing patterns are selected in each scanning pass to address ink drop locations for different portions of the raster lines addressed by each scanning pass. Addressing patterns having various interlacing percentages are selected in order to produce overlapping boundary regions between passes. The overlapping boundary regions minimize the banding effects that occur with inexact ink drop placement.
