PROBLEM TO BE SOLVED: To enable suppression of bronzing by appropriately corresponding to each of various images or recording modes, for instance by suppressing the bronzing at a high level in monochrome image recording in an inkjet recording apparatus.SOLUTION: In a color mode, among clear ink data CL1 and CL2, only the data CL2 is set to a uniform use amount of 20%, while the use amount for the data CL2 is set to zero. Meanwhile, in a monochrome photo mode, the data CL1 indicates a use amount of 10% to 40% near a white point, but starting at the intermediate gradations, the data CL1 use amount decreases while the data CL2 use amount increases, with a data CL2 use amount of 20% near a black point. In this way, 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, suppression of bronzing is possible at a high level, although there is slight reduction in glossiness of printed matter. |
