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.

Abstract: In a system and a method for profiling a digital-image input device, profiling of the digital-image input device is performed based at least on an image of a color chart and an estimated illumination of the color chart generated by comparing illumination of device-dependent coordinate values for the image of the color chart with illumination of device-independent coordinate values of the color chart. Because the estimated illumination of the color chart is performed on data pertaining to the color chart, the present invention may generate a profile without reference to data pertaining to scenery in the image outside of the color chart. Consequently, the present invention may generate a profile irrespective of the relative exposure of the color chart with respect to other scenery in the image.
