Quick
applies one-dimensional transfer curves to adjust output
densities in the cyan, magenta, yellow, and black channels. This
technique leads to pleasant color output from your 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 will be used as
press proofs. Other techniques offer more color simulation
accuracy, which is expected by proofing applications.
•
Full (Source GCR)
provides a complete and accurate simulation
based on colorimetric transformations. Hues are preserved,
even for primary colors. The Gray Component Replacement
(GCR) level that was specified in the original (source) document
is also preserved. Full (Source GCR) is therefore an excellent
simulation technique for the highest quality press proofing
applications.
•
Full (Output GCR)
is also 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 appropriate for most documents
designed for the press, but reproduced on your ES3640e MFP.
Note:
When you specify On for Pure Black Text/Graphics, and
specify Full (Output GCR) for CMYK Simulation Method, the black
text and graphics in your document are printed with 100%
black-only toner.
RGB Separation
The RGB Separation option determines how RGB colors (as well as
Lab and XYZ colors) are converted to CMYK. The name of this
option is meant to be descriptive, since the option defines the
color spaces that will be used by the Fiery to “separate” the RGB
data into CMYK values.
