Under color addition. A method of darkening areas of a printed image by adding colored inks, used when making color separations from RGB to CMYK data. The process works as follows: cyan, magenta and yellow portions are added in shadows and black is accordingly removed. Not all achromatic portions, however, are replaced with black, rather a portion of black is generated according to the principle of chromatic composition from the primary colors cyan, magenta and yellow. The aim is to enhance neutral image depths (gray tones) where the density of black is insufficient.

Undercolor Addition. A prepress term describing a technique of making color separations that increases the amount of cyan, magenta or yellow ink in shadow areas.

Undercolor addition. A technique used to increase the saturation and vibrancy of an image by adding Cyan, Magenta, and Yellow inks to areas where a lot of Black ink is printing. The result is more vibrancy but higher TOTAL INK.
