Gamut-mapping from a source device to a destination device is performed in a perceptually linear color space such as CIECAM02 by separating a source image into primary color components and processing each primary component separately by mapping a source primary hue leaf with a destination primary hue leaf. The mapped primary components are then summed and a resultant destination image is obtained. Alternatively, hue rotation is performed by determining a relative position of an input color between the nearest primary and the nearest secondary color in a source hue wheel. The determined relative position in the source hue wheel is used to find a corresponding location in a destination hue wheel so that the hue angle for obtaining the destination hue leaf can be determined. In both processes, the source and destination hue leafs are mapped using a cusp-to-cusp mapping with a shear mapping process being used to pull in the remaining colors. Finally, results of the mapping process are converted from device-independent color appearance space values to tristimulus values, and from tristimulus values to a color space of the destination device.

The present invention relates to a color image forming device for forming toner images of a plurality of colors on a medium, and is for improving second transfer efficiency from an intermediate transfer body to the medium. The device has image forming units (12-1 to 12-4) for forming the toner images of the plurality of colors on at least one image bearing body (14-1 to 14-4) by a plurality of developing units (22-1 to 22-4) respectively accommodating toner of different colors; an intermediate transfer body (24); primary transfer means (38-1 to 38-4) for primary transferring the toner images of the plurality of colors onto the intermediate transfer body sequentially for the respective colors; and secondary transfer means (45) for secondary transferring the toner images of the plurality of colors on the intermediate transfer body onto the medium. The image forming units form the toner images of the plurality of colors so that the potentials of toner layers transferred onto the intermediate transfer body (24) are progressively lower in the order in which the plurality of colors are transferred. Since the potential of the toner layer directly adhered to the intermediate transfer body is higher, the directly adhered toner layer becomes easier to be secondary-transferred, and thereby, the secondary transfer efficiency is improved and the reproducibility of the secondary color is improved.

Innovations in control and use of chroma quantization parameter ("QP") values that depend on luma QP values. More generally, the innovations relate to control and use of QP values for a secondary color component that depend on QP values for a primary color component. For example, during encoding, an encoder determines a QP index from a primary component QP and secondary component QP offset. The encoder maps the QP index to a secondary component QP, which has an extended range. The encoder outputs at least part of a bitstream including the encoded content. A corresponding decoder receives at least part of a bitstream including encoded content. During decoding, the decoder determines a QP index from a primary component QP and secondary component QP offset, then maps the QP index to a secondary component QP, which has an extended range.

An incremental printer, such as for example an inker printer, produces very small markings (as for example by firing small ink droplets) preferably in a single-pass print mode for text, as well as image applications if desired, to achieve addressable print resolution at least four times higher in the carriage scan axis than in the media advance axis. More preferably the resolution in the scan axis is at least six times, ideally eight times, higher than that in the media advance axis. A preferred form of the invention uses 96 dots / mm (2400 dpi) resolution in the scan axis, in conjunction with only 12 dots / mm (300 dpi) resolution in the media advance axis, without having to employ any dot-depletion algorithms. In one embodiment, the system provides a single-pass color print mode wherein primary colors are printed with eight color droplets of the same primary color in eight adjacent sub-pixels on the 300x2400 grid, and secondary colors are printed with eight color droplets of different primary colors in eight adjacent subpixels on the same grid.

Two such pens provide four inks for color inker printing. Three or more such pens enable a printing system to supply ink of plural dilutions for at least one of the ink colors in the system, and thereby facilitate photographic-quality printing.
