Key features of ColorWise

ColorWise is the color management system (CMS) built into the E100 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 E100. 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 copier 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 E100 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 E100 enables the E100 to simulate a
custom press (or another copier), as well as accurately print colors from a particular monitor
or scanner. In addition, you can create customized ICC profiles for the copier.

INTRODUCTION 10

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 E100. These default settings are applied to all print jobs sent to the E100,
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 E100
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 E100 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 copier or an optional spectrophotometer or densitometer
(see “Calibration” on page 41).

Command WorkStation also allows you to use any Status T densitometer by importing
data in a standard file format (see “Importing Density Measurements” on page 77). 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 offered as part of the optional Productivity Package.

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 E100 and create custom spot color definitions and dictionaries.

• Customizable Auto Trapping

Customizable Auto Trapping is offered as part of the optional Productivity Package.

The customizable Auto Trapping feature provides you with advanced settings for the Auto
Trapping print option. The E100 is shipped with values that are optimized for the copier
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.

INTRODUCTION 11

•ImageViewer

ImageViewer is offered as part of the optional Productivity Package.

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.

• Control Bar

Control Bar is offered as part of the optional Productivity Package.

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

Paper Simulation is offered as part of the optional Productivity Package.

The white point editing feature 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 Mac OS computer is
described in Utilities. Command WorkStation can be installed from the User Software DVD.

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 E100 (see page 13), and detailed explanations of each print option. For the

COLORWISE PRINT OPTIONS 13

Managing color on the E100

Applications allow you to generate color data for the E100 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 E100 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 E100 color management process
that affect color data conversions. You can access these print options when you send a print
job to the E100. 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.

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 toners,
and the stiffness of the media. This illustration shows the same image with and without
trapping.

Auto Trapping Off Auto Trapping On

If you enable the Auto Trapping option, trapping is applied to all of the objects in a job.

The E100 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, and if Productivity Package is configured on the E100, you can modify the values to meet
your requirements. For more information, see Auto Trapping Customization.

Black Detection

The Black Detection option allows you to specify whether or not to detect black-and-white
pages before printing your job.

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 will print with the proper billing information.

COLORWISE PRINT OPTIONS 15

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 copier, 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 toner. This means that black text and line art does not exhibit
halftone artifacts (as long as the copier is calibrated correctly). No transition in cyan and
magenta toners 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 toners on one side (outside the text) and black toner on the other side
(inside the text). This transition may cause visible artifacts due to the practical limitations
of the copier.

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 OPTIONS 16

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 toner only. The black text and line art do not exhibit
halftone artifacts (as long as the copier is calibrated correctly) and are not misregistered, since
one toner 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 Text/Graphics.

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 OPTIONS 17

NOTE: Use the Black Text and Graphics option only when printing composites, not when

printing separations.

Color Black Text and Graphics = Normal Black Text and Graphics = Pure Black On or

Rich Black On

RGB=0,0,0

(All other RGB values are
unaffected by the Black Text
and Graphics setting.)

CMYK=0%,0%,0%,100%

(All other CMYK values are
unaffected by the Black Text
and Graphics setting.)

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 toners 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 toners,
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 toner
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 toners 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 toners according
to the CMYK/Grayscale Source profile. The
output is affected by the calibration curve.

Setting CMYK/Grayscale Source to ColorWise
Off disables the CMYK Source profile and the
calibration curve. In this case, the black toner
is not limited by the calibration curve.

RGB=0,0,0 is printed as K-only, using the black
toner (Pure Black On) or 100% K plus 50%
Cyan (Rich Black On) using black and cyan
toners. 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 toner (Pure Black On) or 100%
K plus 50% Cyan (Rich Black On) using black
and cyan toners, 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 toner
is not limited by the calibration curve.

Spot Colors

(Spot colors are unaffected by
the Black Text and Graphics
setting.)

Standard spot color processing Standard 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 E100. These elements
are not affected by the Black Text and Graphics option. For more information, see Fiery Color

Reference.

COLORWISE PRINT OPTIONS 18

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. The result is pure looking primary 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 toner. 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 copier.

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 toner.

COLORWISE PRINT OPTIONS 19

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 E100 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 27. 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 E100.

The CMYK/Grayscale Source setting that 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 E100 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 E100. For more information about importing ICC profiles to the
E100, 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 copier 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 Photoshop). In this case, the
E100 is expecting to receive CMYK data already in the device color space of the E100.
The E100 will not convert the data, but it will apply calibration.

• The ColorWise Off setting sends your original CMYK data to the copier 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 OPTIONS 20

NOTE: When you print with the ColorWise Off setting, make sure that 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.

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 OPTIONS 21

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 knockout, 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

COLORWISE PRINT OPTIONS 22

Gray (RGB) and Gray (CMYK)

When Gray (RGB) is enabled, any RGB color where R=G=B is printed using only black toner
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 toner 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 Quick, 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.

Output Profile

Because the output profile is applied to all data in the print job, make sure the profile you
select is the right one for your job. The default output profile consists of a profile for your
copier that describes its color characteristics and a calibration target that describes the
expected behavior of the copier.

Use Command WorkStation to import your own output profile to the E100. 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.

The Paper Simulation feature is available with the Productivity Package option on the E100.

You can customize the paper simulation by editing the white point values with Command
WorkStation. For more information, see Paper Simulation White Point Editing.

COLORWISE PRINT OPTIONS 23

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 Paper Simulation option has two settings:

•

Enabled: Performs Absolute Colorimetric rendering.

Disabled (Default): Performs Relative Colorimetric rendering.

•

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 E100 allows you to choose from
the four rendering intents currently found in industry standard ICC profiles.

E100
rendering intent

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 but does not match printed
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

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 E100.
Commonly used monitor color spaces are available from the printer driver and the E100. For
others, use Command WorkStation to download custom monitor or scanner profiles.

When you specify a setting for the RGB Source, the E100 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 E100 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 27. In this case, the RGB Source setting is ignored and the embedded

profile is used instead.

The E100 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, RGB data that
contains an embedded RGB profile is converted using the embedded profile and the RGB/
Lab Rendering Intent option (see “RGB/Lab Rendering Intent” on page 23).

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 E100 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 (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 copier 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 copier.
