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 printer system comprising:
a processor; a printer mechanism configured to jet ink from an inkset onto a substrate having a particular color other than white, wherein the inkset includes a plurality of inks having white ink and an ink having a color other than white; and a mechanism for receiving a media identifier that uniquely identifies a media type and the particular color of the substrate; wherein the processor is configured to retrieve from a stored configuration file, based at least on the particular color of the media type identified by the media identifier, a first offset color value for a first offset color, wherein the first offset color value indicates an amount of the ink other than white; and wherein the printer mechanism is configured to
print on the substrate of the identified media type in a first pass a first layer of ink, including the white ink mixed with the amount of ink other than white indicated by the first offset color value, andprint an image on top of the printed first layer of ink.
