Abstract:
A method for manipulating inking for a digital image printing system comprising the steps of:identifying a printer and a substrate for use in color printing; printing a color test pattern of a plurality of test patches with the identified printer and the identified substrate, where each test patch is printed with a distinct combination of primary inks; reading in the plurality of test patches with a color measurement device to obtain L*a*b* data; comparing each of the plurality of test patches with every other one of the plurality of test patches to generate alternate equivalent inking combinations for matching the color of an original test patch; selecting a preferred inking combination from between the original test patch and the alternate equivalent inking combinations that optimally manipulates the inking of the digital image; compiling a preferred inking substitution table which links each inking combination to its preferred equivalent inking combination to generate the preferred inking substitution table; employing the preferred inking substitution table to identify preferred inking combinations for use in printing color images.
