ABSTRACT:
A method of generating halftone print data for overlapping end portions of a pair of consecutive printhead segments in an array of two or more printhead segments is disclosed. Generally an end portion of a first printhead segment overlaps an end portion of a second printhead segment, in which each printhead segment includes a plurality of ink ejection nozzles. The method includes generating a dither value from a dither matrix, and then combining the dither value with an overlap signal, which represents an extent of overlap of the end portions, to produce an output value. A mathematical operation is then performed on continuous tone print data using a comparator, based on the output value, to produce the half tone data.
