Abstract:
A method to configure an apparatus to apply a plurality of mono colorization filters to a low resolution version of a color image. A contrast value is determined for each application of the mono colorization filters. The mono colorization filter achieving the highest contrast value is applied to a high resolution version of the color image to produce a high contrast monochrome image. The high contrast monochrome image is then printed by the apparatus.
