Abstract
Every time density correction information corresponding to a colorimetric value of a patch is acquired, the time when the density correction information is acquired and the type of a printing medium on which the patch is printed are accumulated in association in a memory. The type of a medium for printing is specified by a user; density correction information acquired at the most up-to-date time for each chromatic color ink available for the medium of that type is read from the memory; it is determined whether or not the most up-to-date time when the density correction information is acquired for each of the chromatic color inks available for the specified medium is the same time; if the most up-to-date times are the same, density correction is performed on image data, using a correction table that corresponds to the density correction information acquired at the most up-to-date time.
