Managing color on the Fiery X3e
Detailed explanations of how these and other settings affect your print jobs are 
provided in subsequent sections of this chapter.
CMYK Simulation Profile
SWOP-Coated/DIC/Euroscale/
Simulation 1-10/None 
(Default set at Setup or in ColorWise Pro 
Tools)
Adjusts CMYK color data to simulate an offset press standard or a custom 
color 
gamut
 defined at your site. Choosing None bypasses simulation (see 
page 1-12
). This option is only available with the PostScript driver.
CMYK Simulation Method
Quick/Full (Source GCR)/Full (Output 
GCR)
(Default set at Setup or with ColorWise Pro 
Tools)
Quick simulation applies one-dimensional transfer curves that adjust output 
density only. The Full simulations apply colorimetric transformations that 
adjust hue as well as output density (see 
page 1-13
). This option is only 
available with the PostScript driver.
RGB Separation
Output/Simulation
(Default set at Setup or with ColorWise Pro 
Tools)
Determines which CMYK 
color space
 your original RGB data will be 
separated into—CMYK for the copier/printer (Output) or CMYK for a 
specified simulation (Simulation). For more information, see 
page 1-14
. This 
option is only available with the PostScript driver.
N
OTE
: When RGB Separation is set to Simulation, RGB colors are affected by 
CMYK Simulation Profile and CMYK Simulation Method.
Output Profile
Output 1-10
(Default set at Setup or with ColorWise Pro 
Tools)
The 
output profile
 is applied to all data in the print job (see 
page 1-15
). User-
defined output profiles can be downloaded to the Fiery X3e using ColorWise 
Pro Tools. For more information about using ColorWise Pro Tools, see 
Chapter 3
This option is only available with the PostScript driver.
Combine Separations
On/Off
Specifies whether to print separated CMYK data as a single, four-color 
composite document (see 
page 1-16
). With Spot-On, you can combine an 
unlimited number of spot 
color separations
 along with the CMYK 
separations.
Image Smoothing
Automatic/Off/On/Below 90–300 ppi
The On setting enhances the print quality of low-resolution images.

Fiery X3e Color Management
Rendering Style
The Rendering Style option specifies a CRD for color conversions. To control the 
appearance of images, such as prints from office applications or RGB photographs 
from Photoshop, select the appropriate Rendering Style. The Fiery X3e allows you to 
select from the four rendering styles currently found in industry standard ICC profiles.
Fiery X3e rendering style
Best used for
Equivalent ICC 
rendering style
Photographic
—Typically results 
in less saturated output than 
presentation rendering when 
printing out-of-gamut colors. It 
preserves tonal relationships in 
images.
Photographs, including scans 
and images from stock 
photography CDs and digital 
camera images.
Image
Contrast
, and 
Perceptual
Presentation
—Creates 
saturated colors but does not 
match printed colors precisely 
to displayed colors. In-gamut 
colors such as flesh tones are 
rendered well; similar to the 
Photographic rendering style.
Artwork and graphs in 
presentations. In many cases, it 
can be used for mixed pages 
that contain both presentation 
graphics and photographs.
Saturation
Graphics
Relative Colorimetric
—Provides 
white-point transformation 
between the source and 
destination white points. For 
example, the bluish gray color 
of a monitor will map to neutral 
gray. You may prefer this style 
to avoid visible borders when 
not printing full-bleed.
Advanced use when color 
matching is important, but you 
prefer white colors in the 
document to print as paper 
white. It may also be used with 
PostScript color management to 
affect CMYK data for 
simulation purposes.
Relative Colorimetric
Absolute Colorimetric
Provides no white point 
transformation between the 
source and destination white 
points. For example, the bluish 
gray of a monitor will map to a 
bluish gray.
Situations when exact colors are 
needed and visible borders are 
not distracting. It may also be 
used with PostScript color 
management to affect CMYK 
data for simulation purposes.

:
The rendering styles associated with the PCL driver do not match those 
associated with the PostScript driver.
Pure Black Text/Graphics
The Pure Black Text/Graphics option affects the printout for black text and 
vector 
graphics
 on a page. Under most circumstances, leave this option set to On. When 
Pure Black Text/Graphics is on, black colors generated by applications (for example, 
RGB = 0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the 
maximum amount of black toner allowed by the calibration curve. This means the 
black text and line art will not exhibit halftone 
artifacts
 (as long as the copier/printer is 
calibrated correctly) and will not be misregistered, since there is only one toner used. 
In addition, this setting eliminates 
blasting
.
For some jobs, it is preferable to clear this option, for example, if the page includes 
gradient
 fills that use black. The following table describes the behavior of the Pure 
Black Text/Graphics option with black data defined in different color spaces.
N
OTE
:
Use the Pure Black Text/Graphics option only when printing composites, not 
when printing separations.

RGB
Prints 100% black
With the default profile, prints a rich black using 
all toners.
CMYK
Prints only with black toner, because CMYK 
simulations preserve the black channel. The actual 
amount of toner used depends on the current 
simulation and the calibration state of the 
copier/printer.
Spot
Prints only with black toner, because spot color 
simulations preserve the black channel. The actual 
amount of toner used depends on the current 
simulation and the calibration state of the 
copier/printer.

Fiery X3e Color Management
N
OTE
:
PostScript applications (such as QuarkXPress) may convert elements defined as 
RGB = 0, 0, 0 to four-color CMYK black before sending the job to the Fiery X3e. 
These elements are not affected by the Pure Black Text/Graphics option. For details, 
see the application notes. Also, black text and line art defined as RGB = 0, 0, 0 in office 
applications (such as Microsoft Word) are converted to single-color black (CMYK = 
0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3 driver for Windows 
2000/XP. To print this single-color black at the maximum toner density of the 
copier/printer, set the Pure Black Text/Graphics option to On. 
N
OTE
:
This feature is not available with the PCL driver.
Black Overprint
The Black Overprint option allows you to specify whether or not black text or 
text/graphics—defined as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%—
overprints colored backgrounds.
Text
—Black text overprints colored backgrounds, eliminating white gaps and 
reducing halo effects or misregistration of colors.
Text & Graphics
—Black text and graphics overprint colored backgrounds, 
eliminating white gaps and reducing halo effects or misregistration of colors.
Off
—Black text or text/graphics knocks out colored backgrounds.
N
OTE
:
PostScript applications may perform their own black overprint conversions 
before sending the print job to the Fiery X3e.
One example of how you might use this setting is with a page that contains black text 
on a light blue background. The background blue color is CMYK = 40%, 30%, 0%, 
0% and the black text is CMYK = 0%, 0%, 0%, 100%. 
• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic 
portions of the page are overprinted, or combined with the underlying colors. Black 
colors generated by applications (for example, RGB = 0%, 0%, 0%; CMYK = 0%, 
0%, 0%, 100%) are printed using the maximum amount of black toner allowed by 
the calibration curve. This means that black text and line art will not exhibit 
halftone artifacts (as long as the copier/printer is calibrated correctly). There is no 
transition in the cyan and magenta toners, and the quality of the output is improved 
since it will not show artifacts near the edges of the text or text/graphics. The option 
also works with text defined in the RGB color space, that is RGB = 0, 0, 0.
