Abstract: It is guaranteed that a designated color that is a target of spot color matching is converted correctly into a destination color thereof at the time of output. In a case where drawing data for causing an image output apparatus to perform drawing of an image is generated, whether a designated color in a first color space, which is included in an input image, is converted into a destination color in a second color space, which can be handled by the image output apparatus, is determined at the time of output of the image. Then, in a case where it is determined that the conversion is performed, control is performed such that color adjustment is not performed for at least the designated color of colors included the input image.

First processing for generating first and second correction data for the first and second printing modes, respectively, by density measurement, or second processing for generating the first correction data by density measurement and generating the second correction data using the generated first correction data and a difference in image density between the first printing mode and the second printing mode is executed. The first processing is executed when a predetermined condition is satisfied.
