Patent ID: 7414752

Claim:
A method of producing color compensation transforms comprising the steps of: using a calibrated scanner to scan at least a first color reference patch and a second color reference patch to produce corresponding first and second scanned color space values, respectively, wherein the first and second color reference patches exhibit respective first and second material compositions that are sufficiently different, one from the other, as to prevent a scanner, calibrated to the first material composition, from producing scanned color space values of as high a degree of accuracy with respect to scannable objects exhibiting at least the second material composition; and combining said first and second scanned color space values with at least the first and second measured color space values to create a compensation table, the first and second measured color space values being a result of the first and second color reference patches having been measured with an optical measuring device; wherein said compensation table is selectively useable as part of said compensation transforms to enable a scanner to produce scanned color space values of substantially as high a degree of accuracy with respect to a scannable object exhibiting said first material composition as with respect to a scannable object exhibiting said second material composition.
