1. An image processing apparatus comprising:
a print control unit configured to control a printing unit to print a first patch image using fluorescent ink and subtractive mixed color ink whose reflectance in an activation wavelength of the fluorescent ink is higher than reflectance in a light-emitting wavelength of the fluorescent ink, and to print a second patch image using the subtractive mixed color ink; and
a processing unit configured to perform, based on a measurement value obtained by measuring the first patch image, calibration processing for the fluorescent ink, and to perform, based on a measurement value obtained by measuring the second patch image, calibration processing for the subtractive mixed color ink.
