Abstract: An example of a color management module is disclosed. The color management module is to generate a mapping from an incoming color space to a printer color space by a color pipeline. In the generation of the mapping, the color pipeline is adjusted so that the mapping of a target color associated with a first composition further includes adding a quantity of a second composition to the mapping of the target color. The second composition comprises a lower visibility than the first composition.

Abstract: A method is described in which image data of an image to be printed is obtained wherein the image data includes data of each colorant to be printed. The image data of each colorant to be printed is analysed to detect areas of the image in which dye-enriched colorant will occur during printing. The image data is modified to compensate for over-saturation due to the dye-enriched colorant in the detected areas and the image is printed based on the modified image data.
