Abstract: An image processing system and method provide for receiving a digital document page to be printed. The page includes a background region for which no color is specified. A user is presented with an option to select a print medium from a set of print media of different colors and to select an option for a color of the selected print medium be used as a color of a background layer of the digital document page. When the option is selected, a background layer is inserted into the page. A print job incorporating the processed digital document page is output to an associated printer that is configured to convert the color of the background layer to colorant values that use the print media as a colorant for rendering at least a part of the background region.

Abstract: Systems and methods for reducing toner usage. A print job is received into a print engine. The print engine comprises a processor, and the print job comprises an image. A halftone screen is applied to the pixels of continuous image data for the image. The processor produces a threshold array of pixel values based on the halftone screen. The processor generates a mask based on the halftone screen for each color plane of the image. The processor applies the mask to the threshold array, creating a modified threshold array. The modified threshold array corresponds to relatively reduced toner usage for rendering the image.

Abstract: A system and method are provided which enable a print media color to be used, as a replacement for a mixture of one or more colorants, in rendering portions of a print job. One or more multidimensional look-up tables are provided. Each table provides for an identified input color, in a device-independent space, to be equated to no colorant, when printed on the respective print media. The identified input color is one of a set of input colors, which, when printed and measured, has an output color that is closest to a measured color of the print media.
