Disclosed is an iterative model based gray balance algorithm that simplifies the color printer calibration and characterization process in electrophotographic printers by helping to set Cyan, Magenta, and Yellow, Tone Reproduction Curves (TRC) so that patches with C=M=Y are gray. Such TRC's are called gray balanced. Finding the CMY combinations that give gray involve searching a three-dimensional space.
