Abstract
An inkjet printer forms ink images from image data including colors in a device independent color space. A color profile associated with the printer maps a plurality of colors in the device independent color space and to a plurality of ink colors formed from a plurality of inks in the printer. The plurality of ink colors only includes colors that are formed with an ink mass density that is below a predetermined threshold.
Claims20
A method of operating an inkjet printer comprising:
- generating a first device dependent printer model that maps a plurality of colors formed from a plurality of inks in the printer and a first plurality of colors in a device independent color space;
- generating a second device dependent printer model that maps the plurality of colors formed from the plurality of inks and a second plurality of colors in the device independent color space with reference to the first device dependent printer model, the second device dependent printer model including only colors in the device independent color space that correspond to colors formed from the plurality of inks with an ink mass density that is below a predetermined threshold;
- generating a color profile mapping between the second plurality of colors in the device independent color space and the plurality of colors that are formed from the plurality of inks with an ink mass density that is below the predetermined threshold;
- and
- storing the generated color profile mapping in a memory associated with the printer.
2 more elements
An inkjet printer comprising:
- a plurality of inkjets arranged in a print zone and configured to form ink images with a plurality of inks on a print medium;
- a memory associated with the printer and configured to store:
- a color profile mapping between a plurality of colors in a device independent color space and a plurality of ink colors formed from the plurality of inks, the plurality of ink colors only including colors that are formed with an ink mass density that is below a predetermined threshold;
- and
- a controller operatively connected to the plurality of inkjets and the memory, the controller being further configured to:
- identify a plurality of colors in color image data corresponding to the device independent color space;
- identify a plurality of the ink colors corresponding to the plurality of colors in the color image data with reference to the color profile mapping;
- and
- operate the plurality of inkjets to eject the plurality of inks onto the print medium to form a printed ink image with the identified plurality of ink colors, the printed ink image having an ink mass density that is below the predetermined threshold.
