Abstract
A printing device includes a unit acquiring first image data having pixel data corresponding to a pixel value of an M value corresponding to each color of the color image; a unit storing nozzle information related to banding; a unit creating second image data by changing a pixel data value corresponding to an abnormal nozzle in the first image data; a unit creating printing data by converting the second image data into dot forming pattern data; and a unit that prints a color image constructed by the second image data. The second image data creating unit changes a pixel data value corresponding to the abnormal nozzle into a value for reducing the banding, and thereafter, changes a pixel data value of a different color nozzle so the predetermined color is within the same color range, in an image portion of the predetermined color.
