Abstract
In a color mode, among clear ink data CLand CL, only the data CLis set to a uniform use amount of 20%, while the use amount for the data CLis set to zero. Meanwhile, in a monochrome photo mode, the data CLindicates a usage of 10% to 40% near a white point, but starting at the intermediate gradations the data CLuse amount decreases while the data CLuse amount increases, with a data CLuse amount of 20% near a black point. In so doing, it is possible to sufficiently suppress bronzing in the color mode where coloring ink data exists, without imparting a particularly strong unnatural look except for specific colors. Meanwhile, in the monochrome photo mode where coloring ink data does not exist, high-level suppression of bronzing is possible, at the cost of a slight reduction in the glossiness of the printed material.
