ABSTRACT:
A system and method for creating gamma correction data for a hardcopy device includes generating a data pattern, the data pattern including data representing color pixels and monochrome pixels, dithering the color pixels of the data pattern, and error diffusing the monochrome pixels of the data pattern such that the dithered color pixels and the error diffused monochrome pixels are each N-bit values, N being greater than one. A test pattern is generated based on the dithered color pixels and the error diffused monochrome pixels. The test pattern is scanned into scanned image data, and a plurality of color gamma correction curves and a monochromatic gamma correction curve are generated from the scanned image data.
