Expand description
See BlackGenerationFunction
, too. Undercolor removal reduces the amounts
of the cyan, magenta, and yellow components to compensate for the amount of
black that was added by black generation.
The undercolor-removal function computes the amount to subtract from each of the intermediate c, m, and y values to produce the final cyan, magenta, and yellow components. It can simply return its k operand unchanged, or it can return 0.0 (so that no color is removed), some fraction of the black amount, or even a negative amount, thereby adding to the total amount of colorant.
