GCR (Gray Component Replacement)
A method of black generation that replaces a certain percentage of CMY with equivalent amount of K. Creates the optimal balance between three and four-color black.
In Four-color Process Printing, black is made up of a combination of the three primary colors. GCR determines how much black to print with black ink, and how much black to print with the remaining three colors where those three inks overlap.
Within ONYX, we are controlling how much black ink to add used based upon a grayscale CMY ink image. The start point is the point relative to CMY ink where black ink is added. If there is any removal of CMY it is due to an adjustment of Total Ink.
