Color correction table creation method, color correction table creation apparatus, and non-transitory computer readable medium for storing program

A color correction table creation apparatus for creating a color correction table for correcting a device-dependent value used as printing data to be input to a printing apparatus, wherein the color correction table creation apparatus is configured to execute,

• an output value acquisition step of acquiring, as an output value, a colorimetric result for a printed matter created by inputting a specific device-dependent value to the printing apparatus;
• an input value acquisition step of acquiring, as an input value for the color correction, a device-dependent value for a printed matter created by a reference printing apparatus to achieve the output value acquired;
• a correction value acquisition step of acquiring the specific device-dependent value as a correction value corresponding to the input value;
• a creation step of creating the color correction table utilizing a relationship between the input value and the correction value;
• and
• a supplementation step of supplementing the relationship between the input value and the correction value, wherein
• in the creation step, the correction value is determined by utilizing a result of the supplementation for at least some of a plurality of the input values to be stored in the color correction table, and
• in the supplementation step, a spline function is used.
