Abstract:
A method of generating half tone print data is disclosed. The method starts by determining an extent of overlap caused by temperature variations of overlapping end portions of a pair of consecutive printhead segments. A dither value is also generated from a dither matrix, and the dither value is combined with the extent of overlap to produce an output value. A mathematical operation is performed on continuous tone print data based on the output value, to produce the half tone print data.
