    Gray Component Replacement, abbreviated GCR, is a technique for replacing gray tones otherwise made from yellow, cyan and magenta separations instead with black ink.

    Advantages of GCR include:
    • Black ink can be less costly than CMY inks.
    • Resulting output is less susceptible to changes and shifts since you are not so heavily relying on the balance as much C, M, and Y.
    • Brighter colors can sometimes be obtained on lower grade papers through the use of GCR.
    Disadvantages of GCR include:
    • GCR may reduce the ability to adjust some colors.
    GCR is also termed "achromatic color removal."
