Under color removal

In printing, under color removal (UCR) is a process of eliminating overlapping yellow, magenta, and cyan that would have added to a dark neutral (black) and replacing them with black ink only, called a Full Black, during the color separation process. Under color removal is used in 4-color (or more colors) printing. Black ink used to add details and darkness in shadowed areas is called a Skeletal Black.
