Patent ID: 7773260

Claim:
An image processing method for recording an image on a recording medium using a plurality of color materials including a chromatic material and an achromatic material, wherein a total amount of recording of the chromatic material is smaller than a total amount of recording of the achromatic material, and a plurality of monochrome modes are provided, the total amount of recording of the chromatic material being different for each of the monochrome modes, and wherein the image processing method comprises: a comparing step of performing a comparison between a recording density of an image recorded on the recording medium in a first monochrome mode included in the plurality of monochrome modes and a recording density of an image recorded on the recording medium in a second monochrome mode included in the plurality of monochrome modes; and an adjusting step of adjusting the amount of recording of the achromatic material on the basis of the result of the comparison performed in the comparing step so that the recording density of the image recorded in the first monochrome mode and the recording density of the image recorded in the second monochrome mode become equivalent to each other with respect to the same luminance signal.
