Abstract
The use amount of clear ink is set to minimize the hue difference Δθs−d from each of the colors corresponding to input signal values. The use amount of the clear ink to provide the minimum hue difference Δθs−d is varied depending on the use amount of color ink used for the color corresponding to the input signal value. A color conversion table having output values of the use amount and ink color data corresponding to the use amount is set. The color conversion in such a relationship is performed, whereby the bronzing color is recognized as a color close to the print color. As a result, undesired bronzing is lessened, so that degradation in image quality can be suppressed.
