PROBLEM TO BE SOLVED: To solve the problem that a color conversion table for performing high-precision color conversion can be hardly created by easily and accurately correcting the color conversion table, without being affected by a human-caused element such as skill of a corrector. SOLUTION: A plurality of ink quantity data, which are specified by the color conversion table, are corrected by referring to the color conversion table which specifies a corresponding relationship between color data in a prescribed color space and the ink quantity data indicating the quantity of ink of each color for use in a printer. In this case, the plurality of ink quantity data are acquired from color conversion table data indicating the color conversion table; evaluation function data, which indicate an evaluation function for evaluating smoothness of a change in color gradation, indicated by the plurality of specified ink quantity data, are acquired; and the ink quantity of the plurality of ink quantity data is corrected so that the evaluation of the evaluation function can be enhanced.
