Abstract
A color processing device includes a color data acquisition section that acquires color data of a first image output by a first image forming device on a basis of image data, a variation acquisition section that acquires a degree of color variation of the image data, a misregistration acquisition section that acquires an amount of misregistration between the image data and the color data in a region exhibiting a high degree of color variation, a first-relationship generation section that generates, after misregistration correction, a first relationship in a region exhibiting a low degree of color variation, and a conversion relationship generation section that generates a conversion relationship in accordance with the first relationship and a second relationship provided for a second image forming device such that colors of a second image to be output by the second image forming device and the first image are made to match.
