A color image processing device uses a dither pattern of blocks, each including a plurality of dots representing the gradations of each pixel of an image in a prescribed print region. The dots including one block are arranged in a growth sequence in the ascending order of gradation, and print data is written sequentially at the dots the number of which corresponds to the gradation associated with the block. An extracting unit extracts a data region holding the color components from the print data. A dither processing unit generates dither patterns for the color components extracted by the extracting unit. The dither processing unit detects whether one or more of the dots including each of the pixels forming the image are outside the data region, and moves any dot outside the data region to a certain dot including the same pixel and existing in the data region. |
