Claim 0:
1. An image processing apparatus comprising:
a print control unit configured to control a printing apparatus to print a patch image for estimating a discharge amount of fluorescent ink on a printing medium using the fluorescent ink and subtractive mixed color ink;
a measurement control unit configured to control a measuring apparatus to measure the patch image;
an estimation unit configured to estimate the discharge amount of the fluorescent ink based on a measurement value obtained by measuring the patch image; and
a correction unit configured to correct, based on the estimated discharge amount, a density output by the printing apparatus with respect to an input color value,
wherein the print control unit controls the printing apparatus so that a dot of the fluorescent ink in the patch image is covered by at least one dot of the 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.
