CMYK/Grayscale Processing Method
The CMYK/Grayscale Processing Method allows you to define your preferred
CMYK-to-CMYK conversion technique.
•
Pure Primaries prints primary colors in a job (C only, M only, or Y only) as primary colors,
using only a single colorant. Secondary colors (M+Y, C+Y, and C+M) are printed as
secondary colors, using only two colorants. The result is pure looking primary and
secondary colors, with minimal banding in gradients.
Pure Primaries compromises overall color accuracy. Do not use Pure Primaries if color
accuracy is important, such as when printing press proofs.
•
Full (Source GCR) provides a complete and accurate simulation based on colorimetric
transformations. Hues are preserved, even for primary colors. The Gray Component
Replacement level specified in the original (source) document is preserved. Process black
expressed in CMY is reproduced using CMY dry ink. Full (Source GCR) is recommended
for the highest quality press proofing applications.
•
Full (Output GCR) is a complete and accurate simulation method based on colorimetric
transformations. Hues are preserved, even for primary colors. With this method, the Gray
Component Replacement (GCR) level that was specified in the original document is not
preserved. Instead, all CMYK data is reseparated using the GCR level specified by the
output profile. This simulation technique is similar to traditional ICC color matching
methods and is more appropriate than Full (Source GCR) for full color printing designed
for the press, but reproduced on your digital press.
NOTE: When you specify Pure Black On for Black Text and Graphics and Full (Output GCR)
or Full (Source GCR) for CMYK/Grayscale Processing Method, the black text and graphics in
your document are printed with 100% black-only dry ink.
