ABSTRACT:
A method for modifying an input digital image having an (x,y) array of image pixels, each image pixel having an input code value for each of four or more color channels, to produce a depleted digital image subject to a total colorant amount limit. The method includes determining depleted code values for each color channel such that the depleted code values produce substantially the input perceived color according to a device color model.
