摘要：
When gradation expression is made for cyan, for example, overprinting by ink C' of a low concentration of cyan is done to express low gradation portions, and high gradation portions are expressed by adding a blue ink B of a high concentration and a green ink G of a high concentration to the former. In expressing the high gradation portions, a hue in the high gradation portions can be changed delicately by changing a discharge ratio of the blue ink B of a high concentration to the green ink G of a high concentration, and color reproducibility can be improved.
