Abstract
The first printing mode improves gloss uniformity by setting the colorless ink discharge amount to be equal to or smaller than a reference value A at a dark image portion in input image data, and performing normal discharge printing in which printing with a colorless ink starts before completion of printing with a color ink (FIG.C). The second printing mode implements a wide color reproductive range by setting the colorless ink discharge amount to be larger than A at the dark image portion, and performing post-discharge printing in which discharge of the colorless ink starts after completion of printing with the color ink (FIG.D).
