Abstract: A method for performing color conversion includes configuring a color transformer to perform black point scaling when converting image data from a source device to a destination device. Another method for performing black point adjustment while performing color management conversions includes determining a device independent black reference vector for a device that corresponds to a predetermined set of device dependent values for that device. Converting the device dependent values to device independent data and adjusting the device independent data based on the device independent black reference vector.

Abstract: A method includes obtaining a chromatic correction for a display device based on a device-dependent display profile. The method may ensure that images that appear on a display device in a soft proofing environment will be visually equivalent to images that appear on print media.

Abstract: A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by recursively reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.

Abstract: This invention provides methods for predicting calorimetric measurements of subtractive colors, in particular, when there is a measurable colorimetric change in one or more individual colorant relative to a set of baseline measurements. The invention is useful for, among other things, imaging applications or soft proofing environments to improve color modeling without requiring significant empirical measurements for adjustments to color models.
