US Patent 7517037 Method for controlling nozzle firing in overlapped printhead segments

A method of controlling the firing of nozzles within overlapped segments of a printhead is provided, in which temperatures of adjacent segments are measured to determine an overlapped region of the adjacent segments and a half toning firing pattern of a continuous tone image for coextensive nozzles of the adjacent segments within the determined overlapped region is adjusted such that VA+VB is greater than V, where VA and VB are respective independent dither matrix values of the adjacent segments and V is a continuous tone value to be represented.
