摘要：
Provided is a color conversion table creation method for creating a color conversion table for an image forming apparatus which forms an image by performing, on an input color value with total use amount of color material exceeding set amount, a process for reducing the total use amount of color material, the table presenting correspondence between the input color value input to the image forming apparatus and an output color value in a device-independent color space. The method includes: acquiring an input color value of a patch image for creating the table; when the total use amount of color material defined by the acquired input color value is around the set amount, adjusting the input color value to have a smaller difference between the total use amount and the set amount; and creating the color conversion table using the patch image with the adjusted input color value.
