ABSTRACT:
A printing unit prints an image based on print data. The printing unit has characteristics. An input-color-data storing portion stores input color data indicative of colors of inputted image data. The input color data have color component values of a first color group. A print-data generating portion converts the color component values of the first color group stored in the input-color-data storing portion into color component values of a second color group, thereby generating pre-correction print data having a predetermined bit width. A correcting portion converts the pre-correction print data into post-correction print data that is adapted to the characteristics of the printing unit. The correcting portion includes a bit-width correcting portion that generates the post-correction print data having a bit width greater than the predetermined bit width. The bit-width correcting portion selectively increases the bit width based on predetermined criteria.
