Abstract:
1. A method of color management for an image marking device comprising: A) receiving a source color profile which includes a plurality of target colors represented as respective source device independent color space data representations; B) selecting a region of the source color profile for tuning, the region associated with a particular color rendered with the image marking device which is considered to be perceptually unacceptable; C) shifting the source device independent color space data representations associated with the selected region by a predetermined value, the predetermined value associated with a color shift of the region necessary to render the particular color with the image marking device in a perceptually acceptable manner and the predetermined value calculated according to a parameterized exponential mathematical function; D) generating a preprocess color profile for the image marking device by tuning the source device independent color space data representations associated with the selected region to the shifted device independent color space data representations associated with the selected region; and E) generating a destination color profile for the image marking device by associating the device independent color space data representations of the preprocess color profile with respective device dependent color space data representations for rendering the plurality of target colors with the image marking device.
