Abstract:
1. An information generation apparatus comprising: a first holding unit that holds sets of color values acquired by measuring, in advance, colors of patterns printed using a first color material group including color materials of a plurality of colors by amounts of color material used, which are set for the respective color materials, and the amounts of color material used, which are set for the respective color materials of the first color material group, for respective combinations of the amounts of color material used, which are allowed to be set for the respective color materials of the first color material group; a second holding unit that holds sets of color values acquired by measuring, in advance, colors of patterns printed using a second color material group including a color material having a higher infrared ray absorption rate than the plurality of color materials by amounts of color material used, which are set for the respective color materials, and the amounts of color material used, which are set for the respective color materials of the second color material group, for respective combinations of the amounts of color material used, which are allowed to be set for the respective color materials of the second color material group; a unit that selects one pixel value from a pixel value group, which is set in advance, as a selected pixel value; a first calculation unit that specifies color values, differences from a color value of the selected pixel value of which fall within a prescribed range, from a color value group held by said first holding unit on a color space, to which that color value group belongs, specifies amounts of color material used held by said first holding unit to be set with the specified color values, and calculates amounts of color material used of respective color materials, used when a pixel having the selected pixel value is to be printed using the first color material group, by interpolation from the specified amounts of color material used; a second calculation unit that specifies color values, differences from a color value of the selected pixel value of which fall within a prescribed range, from a color value group held by said second holding unit on a color space, to which that color value group belongs, specifies amounts of color material used held by said second holding unit to be set with the specified color values, and calculates amounts of color material used of respective color materials, used when a pixel having the selected pixel value is to be printed using the second color material group, by interpolation from the specified amounts of color material used; a unit that stores, in a memory, the amounts of color material used of the respective color materials of the first color material group calculated by said first calculation unit and the amounts of color material used of the respective color materials of the second color material group calculated by said second calculation unit in association with the selected pixel value; and an output unit that reads out from the memory the amounts of color material used of the respective color materials of the first color material group and the amounts of color material used of the respective color materials of the second color material group, which respectively correspond to pixel values of the pixel value group, which is set in advance, and outputs the readout amounts to a printing apparatus.
