ColorWise
designed to provide both casual and expert users with the best color output for a
variety of purposes. The ColorWise default settings provide high-quality out-of-box
color from many Windows and Mac OS applications. This allows casual users to
achieve quality output without knowing about or changing any color settings on the
Fiery EX3535.
For consistent color, calibrate the Fiery EX3535 on a regular basis. ColorWise Pro
Tools include an easy-to-use calibrator, which allows you to calibrate using either the
scanning unit that is part of the copier or a

ColorWise features allow you to modify printing results. Depending on your particular
needs, you can:
•Set the behavior of
press standards.
•Match PANTONE and other

provide for better color conversion of RGB data with no source information.
xiii Key features of ColorWise
•Define whether RGB data is converted into the full gamut of the copier or whether
it is first converted into the gamut of another device, such as a press standard. This
feature is helpful for making one device behave like another. It is also useful for
evaluating the appearance of the RGB file under different printing conditions
without having to reprocess the RGB data each time.
ColorWise color management (ColorWise)
offers an open color architecture,
allowing users to customize the Fiery EX3535 to meet new printing needs as they arise.
ColorWise supports
ICC profiles
, which are industry standard color profiles that
describe the color behavior of a device. Downloading ICC profiles to the
Fiery EX3535 enables the Fiery EX3535 to simulate a custom press (or another
copier), as well as accurately print colors from a particular monitor or a scanner. In
addition, you can create customized ICC profiles for the copier.
ColorWise also allows you to use any
Status T
densitometer by importing data in a
standard file format (see Appendix B). In this case, it is important to note that the
quality of the instrument used will determine the quality of the
calibration
.

RGB Source Profile is the only color option that applies strictly to RGB color data.
The other options that affect RGB color also affect the more rarely used Lab, XYZ, and
other calibrated color spaces.
NOTE: For users who are familiar with PostScript 3 color, RGB Source Profile affects all
CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to
the Fiery EX3535 in CIEBasedDEFG format, for example, by choosing PostScript
Color Management in Adobe Photoshop, the Fiery EX3535 Rendering Style
selection—which normally affects only RGB data—will also affect this CMYK data.

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 is
calibrated correctly) and will not be misregistered, since there is only one toner used.
In addition, this setting eliminates blasting. This option is automatically set to On
when the Black Overprint option is set to On.
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.
NOTE: Use the Pure Black Text/Graphics option only when printing composites, not
when printing separations.

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. Choosing this setting
automatically activates the Pure Black Text/Graphics option.
• Text & Graphics—Black text and graphics overprint colored backgrounds,
eliminating white gaps and reducing halo effects or misregistration of colors.
Choosing this setting automatically activates the Pure Black Text/Graphics option.
•
Off—Black text or text/graphics knocks out colored backgrounds.
•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 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.
•With Black Overprint Off, the border of the text or text/graphics is on an edge that
has cyan and magenta toners on one side (outside the text) and black toner on the
other side (inside the text). This transition may cause visible artifacts because of the
practical limitations of the copier.
NOTE: This feature is not available with the PCL driver.
1-10 Fiery EX3535 Color Management

Spot Color Matching
The Spot Color Matching option provides automatic matching of spot colors with
their best CMYK equivalents.
• On—The Fiery EX3535 uses a built-in table to generate the closest CMYK matches
of spot colors your copier can produce. (New tables are generated when you add new
output profiles.) With the Fiery Graphic Arts Package, the Fiery EX3535 uses the
CMYK matches determined through Spot-On (see page 3-38).
• Off—The Fiery EX3535 uses CMYK equivalents defined by the spot color
manufacturer, such as PANTONE. These are the same CMYK equivalents used by
applications that include spot color libraries.
For jobs that include spot colors, set Spot Color Matching to On unless you are
printing press simulations. In that case, set Spot Color Matching to Off and choose the
appropriate CMYK Simulation setting (see page 1-21).
For PDF jobs that include spot colors and where the spot colors are not included in the
built-in table, setting Spot Color Matching to On retains the spot color originally
specified. The Fiery EX3535 references the built-in table to generate the closest CMYK
matches of the original spot color.
NOTE: Use the Spot Color Matching option only when printing composites, not when
printing separations.

Spot Color Matching and the PANTONE Coated Color Reference
The PANTONE Coated Color Reference (described in the Fiery Color Reference)
prints differently depending on the Spot Color Matching setting.
• On—The Fiery EX3535 uses a built-in table or, with the Fiery Graphic Arts Package,
the Spot-On color dictionaries (see page 3-38) to generate the best matches of the
PANTONE colors that your copier can produce. The PANTONE number is
printed below each swatch.
• Off—The Fiery EX3535 prints swatches using the CMYK values recommended by
Pantone, Inc. (and used by applications that provide PANTONE color libraries).
The CMYK values used to generate the color, as well as the PANTONE number of
the color, are printed below each swatch. These CMYK values are printed through
the selected CMYK Simulation and Output Profile settings.
NOTE: This feature is not available with the PCL driver.
RGB Source Profile
The RGB source profile setting allows you to define the characteristics of the RGB
data in your document so the appropriate color conversion can occur on the
Fiery EX3535. Commonly used monitor color spaces are available from the printer
driver and from the ColorWise Pro Tools Profile Manager. For special needs, use
ColorWise Pro Tools to download custom monitor or scanner profiles.
When you specify a setting other than None for the RGB Source Profile, the
Fiery EX3535 overrides source color space definitions or profiles that other color
management systems may have specified. For example, if you specified a ColorSync
System Profile on your Mac OS computer, the RGB Source Profile setting overrides it.
In cases where you do not want this setting to override another specified source color
space, choose the None setting.
1-12 Fiery EX3535 Color Management

When you specify a setting other than None for the RGB Source Profile—since the
color space definitions are overridden—the output from the Fiery EX3535 is
consistent across platforms. The Fiery EX3535 RGB Source Profile options are:
• EFIRGB specifies an EFI-defined color space recommended for users who have no
detailed information about their RGB data.
• sRGB (PC) specifies the industry standard definition for a generic Windows
computer monitor.
• Apple Standard specifies the definition of all standard Mac OS computer monitors.
• Other allows you to specify custom RGB source settings. If you choose Other as the
RGB Source Profile setting, you must choose settings for the Gamma, Phosphors,
and White Point options.
• Sources 1-10 specify the definitions you download as RGB source profiles. For more
information about downloading RGB source profiles, see page 3-10.
If you are printing with the PostScript driver from a Windows computer and have
Two-Way Communication enabled, the name of each downloaded profile is
represented in the RGB Source Profile setting menu. If you are printing with the
AdobePS driver from a Mac OS computer, downloaded profiles appear as Source-1
through Source-10. For more information on Two-Way Communication, see the
User Software Installation Guide.
• None instructs the Fiery EX3535 to allow the RGB sources you defined elsewhere,
such as in the application, to be used. When you set RGB Source to None, the
appearance of colors will not be independent of the file type. For example, RGB EPS
files will look different from RGB TIFF files.
With RGB Source set to None, PostScript RGB data that contains a source color
space definition is converted using the CRD specified by the Rendering Style option
(see page 1-12). Non-PostScript RGB data and PostScript RGB data that does not
contain a source color space definition are converted using a general undercolor
removal (UCR) conversion method.
NOTE: This feature is not available with the PCL driver.

CMYK Simulation Profile
The CMYK Simulation Profile print option allows you to print press proofs or
simulations. This setting specifies the offset press standard or other color printing
device that you want to simulate. This option affects CMYK data only.
With the Windows printer drivers, you can also view an unlimited number of custom
Full simulations created using ColorWise Pro Tools. On Mac OS computers, you can
view up to 10 Full custom simulations. The number of custom simulations is limited
by the disk space on the Fiery EX3535.
If you are printing with the PostScript driver from a Windows computer and have
Two-Way Communication enabled, the name of each downloaded or custom profile is
represented in the CMYK Simulation Profile setting menu. If you are printing with the
AdobePS driver from a Mac OS computer, downloaded or custom profiles appear as
Simulation-1 through Simulation-10. For more information on Two-Way
Communication, see the User Software Installation Guide.
The None setting sends your original CMYK data to the copier in its calibrated state,
without conversions to simulate another printer. This setting is not generally
recommended, unless you want to bypass the conversion by ColorWise and use
another color management system.
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
Fiery EX3535 with the CMYK Simulation Profile setting.
•For images that were separated for SWOP, choose SWOP as the CMYK Simulation
Profile setting.
NOTE: To properly simulate a printed image that was separated through the use of an
ICC profile, the same profile must be present on the Fiery EX3535. For more
information about downloading ICC profiles to the Fiery EX3535, see “Downloading
profiles” on page 3-10.
1-14 Fiery EX3535 Color Management

The Match Copy setting bypasses Fiery EX3535 calibration and simulation to
simulate the color of a copy produced by the copier. Use this setting when you print
images scanned with the Fiery Scan plug-in set to Match Copy.
NOTE: This feature is not available with the PCL driver.
CMYK Simulation Method
The CMYK Simulation Method allows you to define your preferred
CMYK-to-CMYK conversion technique.
• 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 copier 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 copier.
NOTE: When you specify On for Pure Black Text/Graphics, and specify Full (Output
GCR) for CYMK Simulation Method, the black text and graphics in your document
are printed with 100% black-only toner.
NOTE: This feature is not available with the PCL driver.

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 EX3535 to
“separate” the RGB data into CMYK values.
The two choices available for this option determine whether RGB data is converted
into the full gamut of the copier (output) or is first converted into the gamut of
another digital printer or press standard (simulation). This feature is helpful for
making one device behave like another for RGB data. For example, if a high-quality
ICC profile is available for another print device, the copier can simulate the behavior
of that device.
RGB Separation is also useful for prepress applications. For example, it allows you to
experiment with the appearance of an RGB scan under different press printing
conditions, without having to convert the RGB data to CMYK data for each
condition. When the desired printing condition is found, convert the file to CMYK,
using the same CMYK simulation profile you used during the experimentation.
NOTE: The RGB Separation print option should be used in conjunction with the
Output Profile or CMYK Simulation Profile print options.
• Output converts all RGB colors into the CMYK color space of your copier (when set
to the printer’s default), or a customized CMYK color space for your copier (when
set to Output 1-10).
• Simulation converts all RGB colors into the CMYK color space for a specified
simulation (select the desired simulation with the CMYK Simulation Profile print
option).
NOTE: This feature is not available with the PCL driver.
Output profile
The output profile is applied to all data in the print job, so make sure the selected
profile is the right one for your job. The default output profile consists of both a profile
for your copier, describing its color characteristics, and a calibration target that
describes the expected behavior of the copier.
1-16 Fiery EX3535 Color Management
1
In certain cases, you may want to customize the default output profile using the
ColorWise Pro Tools Color Editor to achieve particular color effects (see page 3-20). If
you do so, the new customized output profile is applied to all data in the print job.
Changing the output profile only does not affect its associated calibration target (since
the target is based on a copier model). You can edit D-Max values of the calibration
target separately (see page 3-20).
Use the ColorWise Pro Tools Profile Manager to download your own output profile to
the Fiery EX3535 (see page 3-10). Downloaded output profiles are at first associated
with the calibration target that is tied to the default output profile. You can edit
calibration target D-Max values separately.
If you are printing with the PostScript driver from a Windows computer and have
enabled Two-Way Communication, the name of each downloaded or custom profile is
represented in the Output Profile setting menu. If you are printing with the AdobePS
driver from a Mac OS computer, downloaded or custom profiles appear as Output-1
through Output-10. For more information on Two-Way Communication, see the User
Software Installation Guide.
NOTE: This feature is not available with the PCL driver.
Combine Separations
The Combine Separations setting specifies how to print separated CMYK data. With
the Fiery Graphic Arts Package, you can combine an unlimited number of spot color
separations along with the CMYK separations.
The Combine Separations options are:
• Off prints each separation individually.
• On combines separations as a single, composite-color document and automatically
makes these settings for the following print options: Color Mode (CMYK),
Rendering Style (None), Pure Black Text/Graphics (Off), Spot Color Matching
(Off), or Black Overprint (Off).
For information about using the Combine Separations option with applications such
as Adobe Photoshop, see the Fiery Color Reference.
