My prepress supplier said he could enhance our color gamut with GCR , what is this?

G.C.R. is an acronym for Gray Component Replacement and when applied by an experienced prepress provider can greatly increase the gamut of color and hue that a printer can achieve. This removes most of the gray type areas from each color and adds it to the black plate, which will help maintain the definition of the original image and at the same time gives the operator much wider latitude to achieve strong vibrant colors. This in effect removes neutrals that were once three colors and puts them all onto the black printer, which will help maintain hues and color throughout the run.
