  • Patent number: 8786904
    Abstract: Color gamuts of output images based on image output methods of plural image output apparatuses and output media are stored. Plural sets of color reference data for associating a color gamut of the image output request apparatus with color gamuts of output images of the image output apparatuses are stored. It is determined whether an output of image data from the image output request apparatus by one of the image output apparatuses is possible. When it is not possible, another one of the image output apparatuses is determined. A preview image and image data for outputting are generated corresponding to the determined one of the image output apparatuses based on the image data, the profile information of the determined one of the image output apparatuses and the color reference data.
