MULTILAYER WHITE PRINTING WITH WHITE-BALANCE

摘要

White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

主权项

1. A method for printing an image on a substrate, the substrate having a particular color, the method comprising:
receiving from a user an indication of a substrate type on which to print an image, the indication associated with the particular color of the substrate type; retrieving from a configuration file, based at least on the particular color of the substrate type, a first offset color value for a first offset color; wherein a color value indicates an amount of each of the colors of ink used by the printer; in a first pass, printing on a substrate of the substrate type a first layer of white ink mixed with an amount of each colored ink indicated by the first offset color value; wherein the printed first layer of mixed ink appears as a neutral color, so that the particular color of the substrate is not visible; in a second pass, printing the image on top of the first layer; wherein the colors of the image are not modified based on the particular color of the substrate.
