Key features of ColorWise
ColorWise is the color management system (CMS) built into the EX700i and 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 EX700i. ColorWise also allows expert users to
obtain the best color output.
ColorWise features allow you to modify printing results. Depending on your particular needs,
you can:
• Set the behavior of CMYK printing to emulate offset press standards.
• Match PANTONE and other spot colors for the best match when printing using
four-color press conditions or presses with extra, custom plates.
• Select a rendering intent for RGB printing. Rendering intents allow for rich, saturated
printing of presentation graphics, smooth, accurate printing of photographs, and relative
or absolute colorimetric rendering for specialized needs.
• Define the source of incoming RGB color data for better color conversion of RGB data
with no source information.
• Determine whether RGB data is converted into the full gamut of the digital press or is first
converted into the gamut of another device, such as a press standard. This feature is useful
for making one device behave like another for RGB data. It also allows you to evaluate the
appearance of an RGB file under different printing conditions without having to convert
the RGB file to CMYK first.
ColorWise color management (ColorWise) offers an open color architecture, allowing
users to customize the EX700i 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. Note that ICC specification version 4 profiles (profile version 4.2.0.0) are supported
as well as version 2. Downloading ICC profiles to the EX700i enables the EX700i to simulate
a custom press (or another digital press), as well as accurately print colors from a particular
monitor or scanner. In addition, you can create customized ICC profiles for the digital press.
INTRODUCTION10
Color management in Command WorkStation
Designed to give flexible control of color printing, Command WorkStation includes the
following color management and color-related tools:
• Color management
Command WorkStation allows you to set the default settings of the ColorWise print
options for the EX700i. These default settings are applied to all print jobs sent to the
EX700i, unless a user overrides them for an individual job by changing settings in the
printer driver or in Job Properties.
• Profiles
Command WorkStation allows you to manage all of the ICC profiles used in EX700i
workflows. You can also create custom profiles by editing existing CMYK source or output
profiles and saving them as new profiles. The AutoGray feature allows you to adjust the
gray balance of output profiles.
•Calibrator
For consistent color, calibrate the EX700i on a regular basis. Command WorkStation
includes an easy-to-use calibrator, which allows you to calibrate using either the scanning
unit that is part of the digital press or an optional spectrophotometer or densitometer
(see “Calibration” on page 46).
Command WorkStation also allows you to use any Status T densitometer by importing
data in a standard file format. In this case, it is important to note that the quality of the
instrument used determines the quality of the calibration.
• Spot-On (spot colors)
Spot-On is a spot color (named color) manager. You can adjust and manage lists of spot
colors and their CMYK equivalents. The matching lists of spot colors and CMYK values
are known as spot color dictionaries. Spot-On allows you to edit spot color definitions on
the EX700i and create custom spot color definitions and dictionaries.
•ImageViewer
ImageViewer allows you to soft proof and adjust colors in a job before it is printed. You
can use the preview in ImageViewer to verify job placement, orientation, and content, as
well as general color accuracy.
• Image Enhance Visual Editor (IEVE)
IEVE is an image editing application that provides users with a visual workspace to adjust
individual images in a job. With IEVE, you can see the effects of your adjustments and
fine-tune the appearance of an image.
INTRODUCTION11
•Auto Trapping
The configurable Auto Trapping feature provides you with advanced settings for the Auto
Trapping print option. The EX700i is shipped with values that are optimized for the
digital press using regular paper, but if these values do not provide the results necessary for
the media that you use, you can modify the values to meet your requirements.
• Control Bar
The Control Bar feature allows you to add a static color bar and dynamic job information
to each printed page at a user-defined location. The feature can be set as a server default or
overridden on a per-job basis.
• Paper Simulation with White Point Editing
The white point editing feature allows you to allows you to perceptually adjust the hue,
brightness, and saturation of the simulated paper white defined in an ICC profile.
Installing and starting Command WorkStation on a Windows or Apple Mac OS computer is
described in Utilities. Command WorkStation can be installed from the User Software DVD
or, if you have an EX700i Print Server, from the EX700i Print Server over the network.

COLORWISE PRINT OPTIONS
The ColorWise color management system provides print options that affect the output of
objects in various color spaces. By specifying the appropriate settings for each print option,
you can obtain the expected results for your jobs.
About this chapter
This chapter provides an overview of the ColorWise management system, which controls
color on the EX700i (see page 13), and detailed explanations of each print option. For the

about printer drivers, see page 33.
Managing color on the EX700i
Applications allow you to generate color data for the EX700i in many different color spaces.
The most common type of color data produced from office applications is RGB, while
prepress applications generally produce CMYK data. Desktop applications also generate spot
colors, such as PANTONE colors. To complicate matters, a single page may contain a mix of
RGB, CMYK, and spot colors. The EX700i allows you to control the printing of mixed-color
documents with features that apply specifically to RGB, CMYK, or spot color data.
The following diagram illustrates the print options in the EX700i color management process
that affect color data conversions. You can access these print options when you send a print
job to the EX700i. Most of these options and settings are described in subsequent sections of
this chapter.

options are not used. Instead, the RGB/Lab Rendering Intent print option, which normally
affects only RGB data, is used to process the calibrated CMYK data. For more information.

Descriptions of ColorWise print options
The following sections provide detailed explanations of the ColorWise print options and how
these options affect print jobs.
NOTE: For information about the 2-Color Print Mapping print option, see Fiery Graphic Arts
Package.
Auto Trapping
Trapping is a technique where the size of objects is modified so that colors printed next to
each other overlap slightly, to prevent white spaces between two colors. These white spaces, or
“halos,” can be caused by factors such as misregistration, the physical properties of the dry
inks, and the stiffness of the media. This illustration shows the same image with and without
trapping.
Auto Trapping OffAuto Trapping On
If you enable the Auto Trapping option, trapping is applied to all of the objects in a job.
The EX700i is shipped with trapping values that are optimized for a Fiery-driven print device
using regular paper. If these values do not provide the results necessary for the media that you
use, you can modify the values to meet your requirements, if you have the Fiery Graphic Arts
Package, Premium Edition option on the EX700i Print Server or the Productivity Package
option on the Integrated Fiery Color Server. For more information about the Fiery Graphic
Arts Package, Premium Edition option, see Fiery Graphic Arts Package. For more information
about the Productivity Package option, see Auto Trapping Customization.
COLORWISE PRINT OPTIONS15
Black Detection
The Black Detection option allows you to specify whether or not to detect black-and-white
pages before printing your job. To use this option, set Color Mode to CMYK.
•
Off: Select Off if your job consists of black-and-white text pages combined with a
significant number of color pages.
•
On: Select On if you are printing a predominantly black-and-white job. Black-and-white
only pages print with the proper billing information.
Black Overprint
The Black Overprint option allows you to specify whether or not black text or black text and
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 the
halo effect or misregistration of colors. You can choose this setting only if the Black Text
and Graphics option is set to Pure Black On.
•
Text & Graphics: Black text and graphics overprint colored backgrounds, eliminating
white gaps and reducing halo effects or misregistration of colors. You can choose this
setting only if the Black Text and Graphics option is set to Pure Black On.
•
Off: Black text or text/graphics knocks out colored backgrounds.
NOTE: Before sending the print job to the digital press, PostScript applications may perform
their own black overprint conversions.
One example of how you might use this setting is a page that contains black text on a light
blue background. The background blue is CMYK=40%, 30%, 0%, 0%. 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 color. Black colors
generated by applications (for example, RGB=0, 0, 0 or CMYK=0%, 0%, 0%, 100%) are
printed using the black dry ink. This means that black text and line art does not exhibit
halftone artifacts (as long as the digital press is calibrated correctly). No transition in cyan
and magenta dry inks occurs. The quality of the output is improved, because it does not
show artifacts near the edges of the black text.
• With Black Overprint Off, the border of the text or text/graphics is on an edge that has
cyan and magenta dry inks on one side (outside the text) and black dry ink on the other
side (inside the text). This transition may cause visible artifacts due to the practical
limitations of the digital press.
NOTE: The reproduction of CMYK components is affected by the CMYK/Grayscale Source
setting and calibration curve when CMYK is not 0%, 0%, 0%, 100%.
COLORWISE PRINT OPTIONS16
Black Text and Graphics
The Black Text and Graphics option affects black text and vector graphics. Under most
circumstances, set this option to Pure Black On. When Black Text and Graphics is set to Pure
Black On, black colors generated by applications (for example, RGB=0, 0, 0 or CMYK=0%,
0%, 0%, 100%) are printed using black dry ink only. The black text and line art do not
exhibit halftone artifacts (as long as the digital press is calibrated correctly) and are not
misregistered, since one dry ink is used. In addition, this setting eliminates blasting. This
option must be set to Pure Black On if you want to set the Black Overprint option to Text or
Te x t / Gr a p h i c s .
For some jobs, it is preferable to set this option to Normal, for example, if the page includes
gradient fills that use black. The following table describes the behavior of the Black Text and
Graphics option with black data defined in different color spaces.
COLORWISE PRINT OPTIONS17
NOTE: Use the Black Text and Graphics option only when printing composites, not when
printing separations.

RGB=0,0,0 is printed according to the definition
for RGB=0,0,0 in the output profile. This may
be a rich black using all dry inks if the output
profile specifies a rich black, or may be K-only
if the output profile specifies K-only for
RGB=0,0,0. The output is affected by the
calibration curve.
CMYK=0%,0%,0%,100% may be printed as
K-only or as a rich black using all dry inks,
depending on the CMYK/Grayscale Source
setting.
If CMYK/Grayscale Processing Method is Pure
Primaries or if CMYK/Grayscale Source is
Bypass Conversion, CMYK=0%,0%,0%,100%
prints as 100% K and the amount of black dry
ink is limited by the CMYK/Grayscale Source
profile and the calibration curve.
If CMYK/Grayscale Processing Method is Full
(Output GCR), CMYK=0%,0%,0%,100% is
printed as a rich black using all dry inks
according to the output profile. The output is
affected by the calibration curve.
If CMYK/Grayscale Processing Method is Full
(Source GCR), CMYK=0%,0%,0%,100% is
printed as a rich black using all dry inks
according to the CMYK/Grayscale Source
profile. The output is affected by the calibration

RGB=0,0,0 is printed as K-only, using the black
dry ink (Pure Black On) or 100% K plus 50%
Cyan (Rich Black On) using black and cyan dry
inks. All other RGB values are unaffected by the
Black Text and Graphics setting.
CMYK=0%,0%,0%,100% is printed as K-only,
using the black dry ink (Pure Black On) or
100% K plus 50% Cyan (Rich Black On) using
black and cyan dry inks, regardless of the
CMYK/Grayscale Source and CMYK/Grayscale
Processing Method settings. All other CMYK
values are unaffected by the Black Text and
Graphics setting.
Setting CMYK/Grayscale Source to ColorWise
Off disables the CMYK source profile and the
calibration curve. In this case, the black dry ink
is not limited by the calibration curve.
Spot Colors
(Spot Colors are unaffected
by the Black Text and
Graphics setting.)
Setting CMYK/Grayscale Source to ColorWise
Off disables the CMYK Source profile and the
calibration curve. In this case, the black dry ink
is not limited by the calibration curve.
Standard spot color processingStandard spot color processing
NOTE: 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 EX700i. These
elements are not affected by the Black Text and Graphics option. For more information, see
Fiery Color Reference.
COLORWISE PRINT OPTIONS18
CMYK/Grayscale Processing Method
The CMYK/Grayscale Processing Method allows you to define your preferred
CMYK-to-CMYK conversion technique.
•
Pure Primaries prints primary colors in a job (C only, M only, or Y only) as primary colors,
using only a single colorant. Secondary colors (M+Y, C+Y, and C+M) are printed as
secondary colors, using only two colorants. The result is pure looking primary and
secondary colors, with minimal banding in gradients.
Pure Primaries compromises overall color accuracy. Do not use Pure Primaries if color
accuracy is important, such as when printing press proofs.
•
Full (Source GCR) provides a complete and accurate simulation based on colorimetric
transformations. Hues are preserved, even for primary colors. The Gray Component
Replacement level specified in the original (source) document is preserved. Process black
expressed in CMY is reproduced using CMY dry ink. Full (Source GCR) is recommended
for the highest quality press proofing applications.
•
Full (Output GCR) 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.
NOTE: When you specify Pure Black On for Black Text and Graphics and Full (Output GCR)
or Full (Source GCR) for CMYK/Grayscale Processing Method, the black text and graphics in
your document are printed with 100% black-only dry ink.
COLORWISE PRINT OPTIONS19
CMYK/Grayscale Source or Device Link
The CMYK/Grayscale Source or Device Link 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.
When you specify a setting other than Bypass Conversion or ColorWise Off for the CMYK/
Grayscale Source, the EX700i overrides source color space definitions or profiles that other
color management systems may have specified. In cases where you do not want this setting to
override another specified source color space, choose Bypass Conversion.
If your document contains an embedded CMYK profile that you want to use, select the Use
Embedded Profile If Present (CMYK) option (see “Use Embedded Profile If Present (RGB
and CMYK)” on page 29. In this case, the CMYK/Grayscale Source setting is ignored and the
embedded profile is used instead.
In the printer driver, you can view an unlimited number of custom Full simulations created
using Command WorkStation. The number of custom simulations is limited by the available
disk space on the EX700i.
The CMYK/Grayscale Source 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 EX700i with the CMYK/
Grayscale Source setting.
• For images that were separated for SWOP, choose SWOP as the CMYK/Grayscale Source
setting.
To properly simulate a printed image that was separated using an ICC profile, the same profile
must be present on the EX700i. For more information about importing ICC profiles to the
EX700i, see Command WorkStation Help.
Two settings are available if you want no CMYK simulation:
• The Bypass Conversion setting sends your original CMYK data to the digital press with
calibration applied, but without conversions to simulate another printer.
The Bypass Conversion setting is recommended if you use another color management
system instead of ColorWise (for example, ColorSync or Adobe Photoshop). In this case,
the EX700i is expecting to receive CMYK data already in the device color space of the
EX700i. The EX700i will not convert the data, but it will apply calibration.
• The ColorWise Off setting sends your original CMYK data to the digital press without
calibration applied and without conversions to simulate another printer. The CMYK data
is still subject to maximum density constraints, however.
The ColorWise Off setting is not available as a setting in Command WorkStation Color
Setup or in Server Setup and cannot be the default CMYK/Grayscale Source setting. You
choose this setting for a specific job.
COLORWISE PRINT OPTIONS20
NOTE: When you print with the ColorWise Off setting, make sure the options you choose in
your application do not cause the application to modify CMYK data. If you enable PostScript
Color Management or include an embedded profile, the color data sent by the application is
similar to Lab color. When you print with settings like Let Printer Determine Colors or Let
Photoshop Determine Colors, the application either converts the CMYK data or tags it for
color management. You must specify No Color Management in the application when you
print with the ColorWise Off setting.
Combine Separations
The Combine Separations setting specifies how to print separated CMYK data. It supports:
Cyan, Magenta, Yellow, Black. On the EX700i Print Server, you can also combine one or
more spot colors.
•
Off prints each separation individually.
•
On combines separations as a single, composite-color document, and automatically makes
the settings for the following print options: Color Mode (CMYK) and Black Overprint
(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.
The following applications have been tested with Mac OS and Windows for compatibility
with the Combine Separations option:
• Adobe Illustrator
• Adobe InDesign
• Adobe PageMaker
• Adobe FreeHand
• QuarkXPress
For information about using the Combine Separations option with applications such as
Photoshop, see Fiery Color Reference.
COLORWISE PRINT OPTIONS21
Composite Overprint
When overlapping objects are printed, the foreground object can either overprint or knock
out the background object. With overprinting, the color of the background object shows
through the foreground object where they overlap, and the resulting color is a combination of
the colors of the two objects. With a knock-out, the foreground object hides the background
object where they overlap.
The Composite Overprint print option allows you to print overprinted objects as specified in
the source file. By default, the Composite Overprint print option is off and overlapping
objects print as knockouts.
NOTE: The Composite Overprint option does not overprint the foreground object if it is an
RGB object.
The Composite Overprint print option is supported for PostScript and PDF jobs produced
by the following applications:
• Adobe Acrobat
• Adobe Illustrator
• Adobe InDesign
• Adobe FreeHand
• QuarkXPress
•CorelDRAW
The 2-Color Print Mapping option is ignored when Composite Overprint is enabled.
The 2-Color Print Mapping option is a feature of the Fiery Graphic Arts Package, Premium
Edition, which is an option to the EX700i Print Server.
If Composite Overprint is enabled for a job that contains spot colors, Spot-On must be
enabled on the EX700i.
COLORWISE PRINT OPTIONS22
Gray (RGB) and Gray (CMYK)
When Gray (RGB) is enabled, any RGB color where R=G=B is printed using only black dry
ink instead of processed black. Similarly, when Gray (CMYK) is enabled, any CMYK color
where C=M=Y=0 and K=any value is printed using only black dry ink instead of processed
black.
You can choose to apply the Gray (RGB) or Gray (CMYK) option to either Text and Graphics
or to Text, Graphics, and Images.
The following limitations apply:
• The Gray (RGB) or Gray (CMYK) option has no effect on a job that is pre-separated.
• If CMYK/Grayscale Processing Method is set to Pure Primaries, the Gray (CMYK) setting
does not affect the output.
• If Separate RGB/Lab to CMYK Source is enabled, the Gray (RGB) option is set to Off.
Likewise, if the Gray (RGB) option is not set to Off, you cannot enable Separate RGB/Lab
to CMYK Source.
• If Black Text and Graphics is set to Pure Black On or Rich Black On, it takes precedence
over Gray (RGB) or Gray (CMYK) for 100% black text and graphics.
• If a gray is specified as a spot color, the Gray (RGB) or Gray (CMYK) option does not
affect that gray.
Optimize RGB Transparency
The Optimize RGB Transparency option affects jobs with the following characteristics:
• The job is in PDF format (submitted to the EX700i as a PDF file, not submitted from an
application through a printer driver).
• The job contains transparent RGB or Lab objects. They might be objects that you have
specified as transparent using an application that supports this capability, or they might be
objects with a special effect, such as a drop shadow, that uses transparency to achieve the
effect.
• The transparent objects overlap, creating an area of mixed color.
• The Adobe PDF Print Engine Preferred option is not enabled, which means that the
EX700i converts the PDF job to PostScript when processing the job.
If you enable Optimize RGB Transparency, the EX700i will use the correct RGB source
profile and rendering intent when converting the overlapping RGB colors to CMYK during
the PDF-to-PostScript conversion. If you disable Optimize RGB Transparency, the area of
overlapping colors might print with incorrect color or undesirable artifacts.
Optimize RGB Transparency can result in a longer processing time, especially for VDP jobs
that contain multiple individual PDF pages. We recommend that you enable Optimize RGB
Transparency only when necessary to achieve correct color output.
COLORWISE PRINT OPTIONS23
You can specify Optimize RGB Transparency for a job in Job Properties in Command
WorkStation, Hot Folders, or a virtual printer, but not when you print from the printer
driver. The Optimize RGB Transparency option does not appear in the printer driver because
jobs printed from the printer driver are always submitted to the EX700i as PostScript jobs,
which are not affected by Optimize RGB Transparency.
Output Profile
Because the output profile is applied to all data in the print job, make sure that the profile you
select is the right one for your job. The default output profile consists of a profile for your
digital press that describes its color characteristics and a calibration target that describes the
expected behavior of the digital press.
Use Command WorkStation to import your own output profile to the EX700i. Imported
output profiles that do not already include a calibration target 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.
Select the Use Media Defined Profile setting to automatically apply the output profile
associated with the media type used in a print job, rather than setting a specific output profile.
For more information, see Command WorkStation Help.
Paper Simulation
The Paper Simulation option gives you the benefit of the absolute colorimetric rendering that
renders the white point of the source color space as a visible color in the output profile color
space.
With the Fiery Graphic Arts Package, Premium Edition option on the EX700i Print Server or
the Productivity Package option on the Integrated Fiery Color Server, you can customize the
paper simulation by editing the white point values with Command WorkStation. For more
information about the Fiery Graphic Arts Package, Premium Edition option on the EX700i
Print Server, see Fiery Graphic Arts Package. For more information about the Productivity
Package option, see Paper Simulation White Point Editing.
You can print a job with the Paper Simulation feature set to On from the printer driver
without customizing paper simulation. Many jobs may print satisfactorily with the fixed
default Paper Simulation setting.
The PDF/X Output Intent option is available on the EX700i Print Server, but not on the
Integrated Fiery Color Server.
PDF/X is a subset of the PDF specification. PDF files can contain a variety of elements
(text, graphics, even animations) and it is not always obvious how these elements should be
displayed or printed. PDF/X was designed with a focus on high-quality printing. It excludes
the use of PDF features that are not appropriate for graphic arts and adds features that prevent
ambiguities related to printing. A PDF/X compliant document contains embedded
information about the intended printing conditions for the document.
The PDF/X Output Intent option, when enabled for a PDF/X job, specifies that the EX700i
use the PDF/X output intent embedded in the PDF/X document. Typically, whether you use
this option depends on whether you are using the EX700i for proofing or production (final)
printing.
Prints for proofing are expected to look exactly like the output of the final production device,
regardless of the capabilities of the EX700i or digital press. For instance, when proofing
Newsprint, you want the color gamut of the digital press to be very limited compared to its
capabilities. In production, you usually want to maximize the use of the digital press gamut by
applying specific color features of the EX700i or digital press. Even in production, however,
you might choose to limit the color gamut in order to achieve consistency in the color
produced by different devices.
The PDF/X Output Intent option only affects PDF/X files (conforming to the PDF/X3 or
PDF/X-1a standard). It has no effect on non-PDF files or PDF files that are not PDF/X
compliant. Profiles specified by PDF/X files must be embedded in the files, not referenced
from an external locations.
NOTE: With the Fiery Graphic Arts Package, Premium Edition option on the EX700i Print
Server or the Productivity Package option on the Integrated Fiery Color Server, you can use a
Hot Folders filter to determine if a PDF file is PDF/X compliant. For information about this
Hot Folders filter, see Hot Folders Help.
When PDF/X Output Intent is enabled and no other setting conflicts, the EX700i processes a
PDF/X compliant file in a way that produces results defined by the intents and source color
spaces embedded in the file. The EX700i ignores the CMYK/Grayscale Processing Method
and CMYK/Grayscale Source options. The rendering intents in the PDF/X file are used and
the printed output is limited to the color gamut specified by the output profile embedded in
the file.
When PDF/X Output Intent is disabled, the EX700i ignores the PDF/X output intent.
You can specify the PDF/X Output Intent print option for a job in Job Properties in
Command WorkStation, but not when you print from the printer driver. PDF/X files can be
imported directly to the EX700i using Command WorkStation or Hot Folders, but printer
drivers always convert PDF before sending a job to the EX700i. The PDF/X Output Intent
option does not appear in the printer driver.
COLORWISE PRINT OPTIONS25
When you enable PDF/X Output Intent, you must set select the Use Embedded Profile
When Present (RGB) option so that the rendering intent embedded in the PDF/X file is used.
The PDF/X Output Intent and Use Embedded Profile When Present (RGB) options are
accessible from Expert Settings in the Color window of Job Properties.
RGB/Lab Rendering Intent
The RGB/Lab Rendering Intent option specifies a rendering intent for color conversions. To
control the appearance of images, such as prints from office applications or RGB photographs
from Photoshop, select the appropriate rendering intent. The EX700i allows you to choose
from the four rendering intents currently found in industry standard ICC profiles.

Photographic: Typically results
in less saturated output than
presentation rendering when
printing out-of-gamut colors. This
style preserves tonal relationships in
images.
Presentation:

colors precisely to displayed colors.
In-gamut colors, such as flesh
tones, are rendered well. This style is
similar to the Photographic
rendering intent.
Relative Colorimetric:
white-point transformation between
the source and destination white
points. For example, the bluish
white color (gray) of a monitor is
replaced by paper white. This style
avoids visible borders between
blank spaces and white objects.
Absolute Colorimetric:
no white point transformation
between the source and destination
white points. For example, the bluish
white color (gray) is not replaced
by paper white.

RGB Source or Device Link
The RGB Source or Device Link setting allows you to define the characteristics of the RGB
data in your document so that the appropriate color conversion occurs on the EX700i.
Commonly used monitor color spaces are available from the printer driver and the EX700i.
For others, use Command WorkStation to download custom monitor or scanner profiles.
When you specify a setting for the RGB Source, the EX700i overrides source color space
definitions or profiles that other color management systems may have specified. Because the
color space definitions are overridden, the output from the EX700i is consistent across
platforms.
If your document contains an embedded RGB profile that you want to use, select the Use
Embedded Profile If Present (RGB) option (see “Use Embedded Profile If Present (RGB and
CMYK)” on page 29). In this case, the RGB Source setting is ignored and the embedded
profile is used instead.
The EX700i RGB Source options are as follows:
•
EFIRGB specifies an EFI-defined color space recommended for users who have no detailed
information about their RGB data.
•
sRGB (PC) specifies the definition of a Windows computer monitor profile used as the
default.
•
Apple Standard specifies the definition of a Mac OS computer monitor profile used as the
default.
•
Adobe RGB (1998) is an Adobe-defined color space, used in prepress as the default
working space in Photoshop 5.
•
eciRGB is the European Color Initiative (ECI) recommended space for use as an RGB
working color space and color data exchange format for ad agencies, publishers,
reproduction and printing houses.
•
Fiery RGB is an EFI-defined color space recommended for users of office applications. This
color space is similar to EFIRGB but is larger and can provide a more desirable blue
output.
With the Use Embedded Profile When Present (RGB) option enabled, PostScript RGB
data that contains a source color space definition is converted using the RGB/Lab
Rendering Intent option (see “RGB/Lab Rendering Intent” on page 25). Non-PostScript
RGB data and PostScript RGB data that does not contain a source color space definition
are converted using the EFIRGB source profile and Presentation rendering intent.

Separate RGB/Lab to CMYK Source
The Separate RGB/Lab to CMYK Source 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,
because the option defines the color spaces that are used by the EX700i 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 digital press (Separate RGB/Lab to CMYK Source disabled) or is first
converted into the gamut of another digital printer or press standard (Separate RGB/Lab to
CMYK Source enabled). This feature helps make one device behave like another for RGB
data. For example, if a high-quality ICC profile is available for another print device, the
digital press can simulate the behavior of that device.
Separate RGB/Lab to CMYK Source 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/Grayscale Source that you used during the experimentation.
NOTE: Use the Separate RGB/Lab to CMYK Source print option in conjunction with the
Output Profile or CMYK/Grayscale Source print options.
•
Enabled converts all RGB colors into the CMYK color space for a specified simulation
(select the desired simulation with the CMYK/Grayscale Source print option).
•
Disabled converts all RGB colors into the CMYK color space of your digital press.
