Abstract
A method for forming a color transform for a color printing device having a plurality of colorant channels that includes applying a colorant control value transformation function characterized by a set of transformation function parameters. An optimization process is used to optimize a merit function including a gamut shape term. The method involves determining an initial merit function value responsive to an initial gamut shape determined using the initial set of transformation function parameters. Modified transformation function parameters are determined that produce a modified gamut shape and provide an improved merit function value.
