A method of determining whether a page to be printed on a color printer will actually be entirely printed in one colorant, usually black, and if so, automatically omitting whatever processing steps are unnecessary as a result. Determining if the page is monochrome can be done either by (1) including a signal in the PDL or by a signal from the user or by (2) inspecting each element of the page to determine if all elements are specified to be printed in the same one colorant. If either is true, then various color operations such as trapping, color conversion to any other color, and color correction for non-selected colors can be automatically omitted.
