1. A method for execution in a computer, comprising: receiving, as input to the computer, a set of multi-channel transfer curves for each defined region of a color model of conceptual colors of a multi-channel image; receiving, as input to the computer, a digital image file having a plurality of pixel stacks; for each pixel stack in the digital image file: identifying initial percent dot values for the pixel stack; for each defined region of said color model: determining a degree of affiliation between the defined region and the initial percent dot values mapped to a locus on an aberrated hypercube color model; determining an absolute adjustment value prescribed for the defined region's transfer curve for each initial percent dot value; and modifying the absolute adjustment value in response to the degree of affiliation of the defined region; determining an assimilated/accumulated curve adjustment value by summing the modified absolute curve adjustment values of the transfer curves for each defined region; applying the assimilated/accumulated curve adjustment value to the initial percent dot value to generate a color-corrected percent dot value; and replacing the initial percent dot value in the digital image file with the color-corrected percent dot value.
