Abstract: A color processing device includes a color data acquisition section and a first-relationship generation section. The color data acquisition section acquires color data of a first image output by a first image forming device on a basis of image data. The first-relationship generation section generates a first relationship that is a relationship between the image data and the acquired color data, the first relationship being generated by applying the image data and the acquired color data to at least one first relationship candidate prepared in advance in a color gamut wider than a color gamut of the color data and by performing matching on the image data and the acquired color data with the first relationship candidate.

Abstract: A special-purpose image processor can convert an electronic file into a bitmap by generating printing halftone dots within the bitmap based on locations of colors within the electronic file, and generating non-printing dots within the bitmap. A printing apparatus can print the bitmap, by not print marking materials where the non-printing dots are positioned within the bitmap. The special-purpose image processor can generate the non-printing dots within the bitmap by increasing the size of the printing halftone dots until they contact one another, or generating printing lines that connect the printing halftone dots to each other within the bitmap. Also, the special-purpose image processor can generate, as each printing halftone dot, a higher frequency pattern of printing dots, where the non-printing dots are generated to have a lower frequency pattern relative to that higher frequency.
