Abstract
In performing multi-pass printing by using a printhead having a plurality of nozzles, a print data setting unit sets a printing amount for each nozzle for each main scan of the printhead based on a print data setting LUT. This print data setting LUT reflects the information of the number of passes and the number of nozzles to be used which are arbitrarily set. A halftoning unit generates a dot pattern as a formation target by performing binarization processing for the print amounts set in this manner.
