Abstract

A method determines a color ink deposition order when inks of a plurality of colors are overlapped on one another to form an image on a recording medium. The method comprises the steps of: obtaining information on OD_β(α) concerning an ink of a first color α and OD_α(β) concerning an ink of a second color β, where OD_β(α) is a reflection density in a range of a color complementary to the second color β in a deposition sample obtained when only the ink of the first color α is deposited, and OD_α(β) is a reflection density in a range of a color complementary to the first color α in a deposition sample obtained when only the ink of the second color β is deposited; and determining the color ink deposition order so that of one of the inks of the first color α and the second color β which one corresponds to smaller one of OD_β(α) and OD_α(β) is first deposited and the other of the inks of the first color α and the second color β is subsequently deposited.
