Advantages & Problems of GCR
The main advantage of GCR is it reduces the effects of variations on press, so when ink coverage
varies, the colors become slightly lighter or darker, rather than changing hue.
Increased amounts of GCR also allows your printing company to use a somewhat higher proportion
of black ink, thus reducing cost—which saves you money.
High levels of GCR and/or UCR expand the overall gamut, so darker and more saturated colors are
achievable. However, with too light GCR you may not get as saturated a color as with higher levels
of GCR.
Professional CMYK Profiles Package
What You Get with Professional CMYK Profiles Package
“Professional CMYK Profiles” was developed for the serious professional, who is concerned about
productivity, quality separations, and color fidelity.
With “Professional CMYK Profiles”, you get six different UCR/GCR settings that conform to
generic CMYK SWOP, Japanese Ink Standard, and Euroscale standards—Letting you select the best
values for your printing conditions.
Any of these combinations give you the control you need to optimize your separations for your
proofing and printing applications, reduce your printing costs, and minimize ink trapping problems
on press.
However, check with your printer as to the optimal UCR/GCR setting to select for your printing
conditions. The following two pages list the settings for the three standards.
