Abstract
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).
Claims20
A method for improving color balance when printing on colored media, the method comprising:
- receiving, from a sensor, data that indicates a color of the colored media;
- identifying a profile that corresponds to the color of the colored media;
- and
- causing a first layer of ink to be deposited onto the colored media,
- wherein the ink includes at least one color other than white that is determined based on an offset color that is specified in the profile.
A non-transitory medium with instructions stored thereon that, when executed by a processor, cause the processor to perform operations comprising:
- obtaining data generated by a sensor that monitors a characteristic of a substrate to be printed on;
- deriving the characteristic of the substrate by analyzing the data;
- identifying a profile that corresponds to the characteristic;
- and
- causing a layer of ink to be deposited onto the substrate by a printer,
- wherein the ink includes at least one color other than white that is determined based on an offset color that is specified in the profile.
An electronic device comprising:
- a processor;
- and
- a memory having instructions stored thereon that, when executed by the processor, cause the processor to:
- receiving input that is indicative of a request to print on a substrate of a given color or a given type, and
- causing a shading layer to be formed on the substrate, wherein the shading layer is formed with white ink and ink of a color other than white that is determined based on the given color or the given type of the substrate.
