Abstract
A color error diffusion method effective between a color image input device operating in one color space and a color image output device operating in another color space. The method includes the steps of (a) preparing a final color palette for use in a practice of vector error diffusion intermediate the color image input and output devices, and (b) basing that preparing upon a reverse color conversion step which is effectively applied to a generated calibrated color profile associated with operation of the color image input device.
