The CMYK Simulation Method allows you to define your preferred CMYK-to-CMYK 
conversion technique.

•

 applies one-dimensional transfer curves to adjust output densities in the cyan, 

magenta, yellow, and black channels. This technique leads to eye-pleasing color output 
from your digital press because pure primary colors are not “contaminated” by other 

. While it is the fastest simulation method and perfect for drafts, avoid using it 

for final documents that are used as press proofs. Other techniques offer the color 
simulation accuracy required by proofing applications.

•

 provides a complete and accurate simulation based on colorimetric 

transformations. Hues are preserved, even for primary colors. The 

 (GCR) level that was specified in the original (source) document is also 

preserved for K-only text and graphics. Processed black expressed in CMY is reproduced 
using CMY toner. Full (Source GCR) is recommended for the highest quality press 
proofing applications.

•

 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.

When you specify Pure Black On for Black Text/Graphics and Full (Output GCR) for 

CMYK Simulation Method, the black text and graphics in your document are printed with 
100% black-only toner.

The Combine Separations setting specifies how to print separated CMYK data. It supports: 
Cyan, Magenta, Yellow, Black, and one or more spot colors. With the Graphic Arts Package, 
you can combine an unlimited number of spot color separations along with the CMYK 
separations. 

•

 prints each separation individually.

•

 combines separations as a single, composite-color document, and automatically makes 

the settings for the following print options: Color Mode (CMYK), Black Text/Graphics 
(Normal), Black Overprint (Off ), and Spot Color Matching (Off ).

The results of combining the multiple plates are predictable and accurate, regardless of the 
original application used. This feature also fully supports DCS 2.0 file formats when included 
in a PostScript print job from a page layout application.
