ABSTRACT:
The present invention provides a color-control method for use in an image reproducing process where the image is reduced to a plurality of pixels, with each pixel having a color value. The color control method uses a color control program in the image reproduction process. The color control program includes a color correction module and a color separation module. The color correction program provides a method for using HSL values to select which pixels will be color corrected. The color-separation program is used to convert RGB color values to YMCK color values and provides for undercolor removal and black generation. Undercolor removal removes gray components from the hue pixel data and replaces it with black pixel data. The black generation routine provides for the selection of pixels for which black will be added by the input of selected parameter of an HSL slice range.
