Abstract:
1. A method for controlling printing utilizing a plurality of overlapping printheads attached to a rigid frame of a respective plurality of overlapping swathes extending in a print direction with a succession of print lines extending perpendicular to the print direction, each swathe being an area addressed by a respective printhead during printing, there being at least one overlap region where said swathes overlap so that a number of pixels can be printed by either one printhead or a next printhead, the method comprising the steps of: determining, for each pixel in said overlap region whether said pixel will be printed by said one printhead or said next printhead, said determining step including defining for each print line a transition region between a contiguous array of pixels printed by said one printhead and a contiguous array of pixels printed by said next printhead, said transition region extending over a number of adjacent transition pixels in the print line; varying a location of the transition region, in a direction perpendicular to the print direction, between different print lines within the same overlap region; and printing said plurality of overlapping swathes with said plurality of overlapping printheads attached to a rigid frame.
