IMAGE FORMING APPARATUS, APPARATUS FOR FORMING COLOR CONVERSION PARAMETER, TEST IMAGE FORMING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an image forming apparatus higher in precision of color reproduction.

SOLUTION: The printer apparatus 10 pinpoints a region where unevenness or streaks are generated (uneven region). A test image is printed in which dummy patches are arranged at the pinpointed uneven region, and color charts used for formation of a color conversion parameter are arranged at a region other than the uneven region. The dummy patch is composed of color data different from any color chart. In the case of forming the color conversion parameter, the printer apparatus 10 can easily exclude colorimetric values of the dummy patches on the basis of the color data.
