Abstract
A printing apparatus includes: a printing unit configured to eject a color material ink and a reaction liquid; a controller configured to control the printing unit such that the printing unit prints a first test pattern in which a plurality of patches are arranged; a first obtaining unit configured to obtain an optical density for each of the plurality of patches; a second obtaining unit configured to obtain a specular reflection intensity for each of the plurality of patches; and a first generation unit configured to generate correction information based on the optical density obtained by the first obtaining unit, the specular reflection intensity obtained by the second obtaining unit, a first target value of the optical density for a first input value of the color material ink, and a second target value of the specular reflection intensity for a second input value of the reaction liquid.
