A method for utilizing redundant color inks to improve image quality while
minimizing any undesirable effects such as texture or graininess. The
method comprises tessellating the available redundant color space as
defined by the available redundant ink colorants into regions where the
regions are arranged so as to minimize the range of luminance variation
found within the regions. The result is perceived by the eye as less
grainy in texture as well as much more pleasing to the eye.
