    • A converting unit executes a color conversion process for image data according to a normal profile when a determining unit determines that a prescribed setting is not set for the image data. The converting unit executes the color conversion process for the image data according to a colorant-saving profile configured such that an amount of colorant to be used in the colorant-saving profile is smaller than that in the normal profile when the determining unit determines that the prescribed setting is set for the image data. One of a plurality of input color values of the image data is converted to one of the plurality of output color values according to the colorant-saving profile in the color conversion process. The one of the plurality of input color values has a first hue. The one of the plurality of output color values has a second hue different from the first hue.
