摘要： Reducing deterioration of the printing quality due to the deviation of the dot forming position in the case of printing with multiple print heads.The present invention is a printing apparatus for printing by recording ink dots on a print medium while moving a print head group in a main scan direction. In the printing apparatus closer to a center in the sub-scan direction a nozzle is, greater a recording-target pixel rate is set for the nozzle among the plurality of nozzles on each of the print head. The recording-target pixel rate being a rate of pixels in which the nozzle is in charge of a formation of a dot while the nozzle among the plurality of nozzles passing over one raster line.

摘要： Determination of an adjustment value for adjusting the shifting of recording positions is made easier. The adjustment value is one for adjusting the shifting of recording positions in the direction of main scanning when ink drops are ejected and dots formed on a print medium. Patches T21-T25 and patches T31-T35 are printed in order to determine the extent (adjustment value) to which dot formation positions are shifted on a reverse pass during bidirectional printing. Each patch is formed based on the same print data D1 related to yellow (Y), light cyan (LC), and light magenta (LM) dots. Each dot is formed on the forward and reverse passes of main scanning when the patches T21-T25 are formed. The patches are printed by varying the dot recording positions on a reverse pass in small increments. The patches T31-T35 are formed solely on the forward pass of a main scan. The extent (adjustment value) to which the timing for ejecting ink drops with minimal dot formation misalignments is shifted can be determined by selecting from the patches T21-T25 the patch whose print results are the closest to the adjacent patches T31-T35.
