Abstract
Color processing methods and apparatus are provided that blend the gray component replacement ('GCR') level of arbitrarily-specified input color data with an estimate of the GCR level of an output profile, and then converts processed device-independent data to output CMYK data that has a GCR level that substantially matches the GCR level of the input CMYK data. Methods and apparatus in accordance with this invention may be used to receive CMYK data that approximates a spot color, and provide tints of spot colors using an output profile that has a GCR level that differs from the GCR level of the input color data.
