Abstract
While performing main scanning in which a head having a plurality of nozzles that eject ink is moved in prescribed forward and reverse main scanning directions relative to a print medium, print images are printed on the print medium by forming dots in each pixel aligned in the main scanning direction in accordance with print data. The dot formation position misalignment amount for each nozzle is corrected using image pixel value data indicating the existence of image pixels comprising images and adjustment pixel value data indicating the existence of adjustment pixels in which dots are not formed.
