GCR
From ColorWiki
Gray Component Replacement
The replacement of some or all of the CMY inks in a CMYK pixel with enough black ink to restore the pixel to the same visual appearance. (see UCA, UCR).
The advantages of the use of GCR include:
- Ink savings (black ink is less costly than CMY inks, and GCR enables less ink to be used overall),
- Color stability (Printing is less susceptible to color changes and shifts.)
- Sometimes an increase in total gamut can be achieved.
