Brightness (PS only)

Performs a color adjustment on all color channels to make the printed

85% Lightest to 115% Darkest

output lighter or darker.

 

 

CMYK Simulation Method

Quick simulation applies one-dimensional transfer curves that adjust output

Quick/Full (Source GCR)/Full (Output

density only. The Full simulations apply colorimetric transformations that

CMYK Simulation Profile

Adjusts CMYK color data to simulate an offset press standard or a custom

color gamut defined at your site. The Match Copy setting bypasses GA-1121

Euroscale (EFI)/Match Copy/None

calibration to match a copy made from the copier glass. Choosing None
