Information processing apparatus with which deterioration of colorimetric accuracy is suppressed, image forming system including the information processing apparatus, and computer readable storage medium

An information processing apparatus includes: a setting unit configured to set one or more colorimetric regions in an image to be formed based on image data; and a transmission unit configured to transmit a print job to an image forming apparatus, the print job including the image data and colorimetric region information indicating the one or more colorimetric regions. The setting unit has a first mode under which the setting unit selects, based on a selection criterion, a colorimetric region in the image to be formed based on the image data, and a second mode under which a user designates the colorimetric region.
