If you are printing with the PostScript driver and have Two-Way Communication enabled,
the name of each downloaded or custom profile appears in the CMYK Simulation Profile
menu. If Two-Way Communication is not enabled, downloaded or custom profiles appear
as Simulation-1 through Simulation-10. For more information about Two-Way
Communication, see Printing from Windows
The None setting sends your original CMYK data to the copier/printer in its calibrated
state, without conversions to simulate another printer. The ColorWise Off setting sends
your original CMYK data to the copier/printer in an uncalibrated state, without
conversions to simulate another printer.
The CMYK Simulation Profile setting you specify depends on the press standard for
which the CMYK data was separated.
• For images that were separated using a custom separation (such as a separation
produced with an ICC profile), choose the corresponding profile on the CX3641MFP
with the CMYK Simulation Profile setting.
• For images that were separated for SWOP, choose SWOP as the CMYK Simulation
Profile setting.
To properly simulate a printed image that was separated using an ICC profile, the same
profile must be present on the CX3641MFP. For more information about downloading
ICC profiles to the CX3641MFP, see

CMYK Simulation Method

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 copier/printer because pure primary colors are not "contaminated" by other
colorants. 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
Replacement (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.
