Introduction
PhaserMatch Software, Version 4.0
PhaserMatch 4.0 is a color management application for the Phaser 7760, 7750, and 7700
printers. The PhaserMatch software includes both color management and color calibration
functionality. This application creates, edits, and manages TekColor corrections that are used
with these color laser printers. Using PhaserMatch software, a user can modify the color
output from these printers to more closely match a different output device, such as a copy
device or printing press. PhaserMatch can edit device link profiles provided with the
PhaserMatch installation or create entirely new TekColor corrections from industry-standard
ICC profiles. PhaserMatch can manage the TekColor corrections stored on a Phaser 7760 or a
Phaser 7750 printer's internal hard drive.
PhaserMatch can also calibrate Phaser 7760, 7750, and 7700 printers. Color calibration is used
to maintain consistent print results. Color laser printers must be periodically calibrated to
eliminate changes in printed colors caused by environmental conditions, such as temperature
and humidity, and normal wear on printer supplies, such as toner cartridges and imaging units.
Note: When you are using the PhaserMatch software, click the Help (?) button in the upper
right hand corner of the screen to view detailed help about each screen.
PhaserCal Software, Version 4.0
PhaserCal 4.0 is a color calibration application for the Phaser 7760, 7750, or 7700 printers. If
you have installed the PhaserMatch software, you do not need to install the PhaserCal
software. Color calibration is used to maintain consistent print results. Color laser printers
must be periodically calibrated to eliminate changes in printed colors caused by environmental
conditions, such as temperature and humidity, and normal wear on printer supplies, such as
toner cartridges and imaging units.
Note: The calibration procedures are not intended to provide color matching from the printer
to another output device; the full version of PhaserMatch should be used for this purpose.
Users of PhaserCal software who need to create or edit TekColor corrections for their printers
should purchase the full version of PhaserMatch software.
PhaserMatch and PhaserCal 4.0 User Guide

Requirements
PhaserMatch 4.0 and PhaserCal 4.0 software is available for computers running:
■ Apple Macintosh OS X, version 10.2 and later operating systems (For detailed system
requirements, see Macintosh System Requirements on page 7-1.)
■ Microsoft Windows 2000, Windows XP, and later operating systems (For detailed system
requirements, see Windows System Requirements on page 7-1.)
This software supports the Phaser 7760, 7750, and 7700 color laser printers. Other printers by
Xerox and other vendors are not supported.
Installing PhaserMatch/PhaserCal Software
The installer application does not delete existing installations of PhaserMatch. If you do not
want to use a previous version of PhaserMatch, delete the previous versions of PhaserMatch
before installing PhaserMatch 4.0.
Note: You will only need PhaserMatch 3.0 if you are using the scanner-based color profile
creation tool. You can use both versions of PhaserMatch on your system.
Before installing and using PhaserMatch or PhaserCal you should install the appropriate
Xerox-supplied Phaser 7760, 7750 and 7700 PostScript printer drivers on your computer.
If you have both the PhaserMatch and PhaserCal CD-ROMs, you only need to install the
PhaserMatch software. The PhaserMatch software includes the same calibration functionality
as the PhaserCal software. If you install PhaserMatch after you install PhaserCal, only
PhaserMatch is available for use. The installer for PhaserCal does not install PhaserCal if you
have already installed PhaserMatch.

Typical Uses of PhaserMatch Software
Calibrating a Printer
Color calibration is one of the most important things you can do if you want to obtain optimal
color output from your printer. Color laser printers must be periodically calibrated to eliminate
changes in printed colors caused by environmental conditions, such as temperature and
humidity, and normal wear on printer consumables, such as toner cartridges and imaging units.
Calibration may also be necessary if the printer has been used for long extended print runs or
after extended periods of inactivity.
Calibration can be done using one of the following two methods.
■ Method 1 is a spectrophotometer-based calibration done within PhaserMatch/PhaserCal
software.
This is the recommended method for calibration as it provides the most consistent
calibration method for your printer. If you do not have a spectrophotometer, it is suggested
that you consider purchasing one because a spectrophotometer can be a valuable color tool
for your business.
■ Method 2 is a visual calibration done using the control panel of the printer.
Calibration should be performed after the printer is warmed up.
For more information on color calibration, see Printer Calibration on page 2-1.
PhaserMatch and PhaserCal 4.0 User Guide

Typical Uses of PhaserMatch Software
Creating Custom TekColor Corrections
Your Phaser printer has a number of TekColor corrections built into the printer. Try these color
corrections before using PhaserMatch. Using the existing color corrections saves you time
since you do not have to create new color corrections for your printer to get the output you
want. For information on using the built-in color corrections, see the User Guide on the Xerox
website at www.xerox.com/office/support
If none of the TekColor corrections built into the printer meet your needs, you can generate
new TekColor corrections using PhaserMatch. Creating new TekColor corrections can be
accomplished in several ways. The simplest way to create a new TekColor correction is to start
from existing ICC profiles. You can:
■ use an existing ICC device link profile to create a TekColor correction, and then download
it to a Phaser 7760 or Phaser 7750 printer or update the Phaser 7700 printer driver.
■ edit an existing ICC device link profile, and then download it to a Phaser 7760 or
Phaser 7750 printer or update the Phaser 7700 printer driver.
■ create a new device link profile by linking a Phaser printer ICC profile and the ICC profile
of another device, and then download it to a Phaser 7760 or Phaser 7750 printer or update
the Phaser 7700 printer driver.
.
If an existing ICC device link profile meets your needs, you can use the "Download Profiles"
and "Edit Profiles" functionality. Editing or downloading TekColor corrections can save time
because you do not have to create new device link profiles.
If you do not want to use the ICC profiles provided by the PhaserMatch software, you can
create your own ICC profiles by purchasing ICC profile creation software and instruments
from a third party vendor.

In order to obtain the best results from PhaserMatch custom color corrections, a Phaser printer
and target device ICC profile should be created on fully calibrated devices. In PhaserMatch,
the ICC profiles for Phaser printers are called “Phaser printer profiles”. In PhaserMatch, the
ICC profiles for other devices you wish to emulate are called “target device profiles”.
You can use the Phaser printer profiles and target device profiles supplied with the printer and/
or PhaserMatch. If you use the custom installation, you can select to install additional target
device profiles and profiles that simulate some of the printer’s built-in Phaser TekColor
corrections. Use these ICC profiles to create device link profiles, and then you can modify
these device link profiles. When you need to create a new TekColor correction, you need to
create a device link profile.
PhaserMatch and PhaserCal 4.0 User Guide
1-5
Typical Uses of PhaserMatch Software
Creating ICC Profiles
You can use the target device profiles supplied with the printer. To create a new ICC profile,
you will need a third-party profile creation tool. Create new profiles when one of the following
conditions exists:
■ The Phaser printer profile does not meet your needs.
■ You do not have an ICC profile for the device you want the printer to match.
■ The colors produced by the target device have changed due to environmental or other
conditions.
■ The ICC profiles supplied by the device's manufacturer do not meet your needs.
Printing with Custom TekColor Corrections
Printing to a Phaser 7760 or Phaser 7750 Printer
Once a custom TekColor correction is created by PhaserMatch, you can download it to the
hard drive on a Phaser 7760 or Phaser 7750 printer. Each Phaser 7760 and Phaser 7750 can
store up to 10 new TekColor corrections created by PhaserMatch. These new custom TekColor
corrections are then selected in the printer’s PostScript Printer Driver. The custom TekColor
corrections work just like the TekColor corrections that are already built-into the printer, such
as SWOP Press and Euroscale Press. You can also use PhaserMatch to delete the custom
TekColor corrections from the hard drive.
For more information on printing with custom TekColor corrections on a Phaser 7760 or
Phaser 7750 printer, see Printing to a Phaser 7760 or Phaser 7750 Printer on page 4-1 or click
the Help (?) button in the PhaserMatch application.
Printing to a Phaser 7700 Printer
PhaserMatch adds new TekColor corrections to the PostScript printer driver associated with a
Phaser 7700 printer. PhaserMatch modifies the printer driver files to make the new TekColor
corrections available in the driver on the computer being used. The custom TekColor
corrections work just like the TekColor corrections, such as SWOP Press and Euroscale Press,
built into the printer.
For more information on printing with custom TekColor corrections on a Phaser 7700 printer,
see Printing to a Phaser 7700 Printer on page 4-3 or click the Help (?) button in the

Printer Calibration
Spectrophotometer-Based Calibration
There are two methods provided for entering the calibration data values measured by a
spectrophotometer. The first method allows you to use PhaserMatch or PhaserCal software to
control and communicate with a spectrophotometer that is connected to your computer. The
second method allows you to manually import LAB measured data.
The spectrophotometers that can be controlled by PhaserMatch or PhaserCal software are:
■ GretagMacbeth Spectrolino/SpectroScan
■ GretagMacbeth Eye-One System
■ X-Rite DTP-41
■ X-Rite DTP-70
■ X-Rite PULSE
■ X-Rite Digital Swatchbook
■ SpectroStar SpectroCam
Note: PhaserMatch and PhaserCal software do not support any densitometers for performing
a color calibration procedure.
PhaserMatch and PhaserCal software walks you through a series of steps that generate and
download the calibration data to a printer.
To perform a spectrophotometer-based calibration:
1. Launch the PhaserMatch or PhaserCal application.
2. Click the Calibrate Printer button in the main screen.
3. Click the Spectrophotometer-Based Calibration button in the main Calibrate Printer
screen
4. Select a device from the list of supported spectrophotometers or select Manually Enter
Data.
5. Select a printer, print quality, and paper type you use to do the calibration procedure.

page 7-1.
7. View the measurement data.
8. Send the calibration data to the printer.
For more information on how to use these screens, click the Help (?) button in the application.
Visual Color Calibration
The printer contains a set of instructions that describe how to calibrate the printer visually.
These instructions can be printed from the control panel, PhaserMatch, or PhaserCal. The
printed color-balancing tutorial explains how to perform a visual color calibration.
Note: Using a spectrophotometer to do color calibration gives you the optimal printed colors
on your Phaser printer.
PhaserMatch and PhaserCal 4.0 User Guide
2-2
Creating Custom TekColor Corrections
The Phaser printer should have been calibrated using one of the methods mentioned previously
in this document before creating new TekColor corrections. When the printer has been color
calibrated you can create and use custom TekColor corrections.
To create a TekColor correction using a Phaser printer ICC profile and a target device ICC
profile:
1. Launch the PhaserMatch application.
2. Click the Create Profile button in the main PhaserMatch screen.
3. Create a device link profile, see Creating Device Link Profiles on page 3-1.
4. Create a new custom TekColor correction; see Creating Custom TekColor Corrections on
page 3-2.
Creating Device Link Profiles
PhaserMatch software enables you to perform color matching between two devices: your
Phaser color printer and another output device such as a printing press or another printer. It
does this through the creation of a Device Link Profile (DLP). A device link profile is an ICC
profile that combines the color information about the printer and the target device into one file.
Creating device link profiles enables you to alter the colors printed by your Phaser printer so
they more closely match the colors produced by the output device of your choice.
PhaserMatch works with the following types of profiles.
■ Phaser printer ICC profiles that get installed as part of the standard installation.
■ Phaser printer ICC profiles that get installed as part of the optional software install. These
are ICC profiles that simulate the TekColor corrections that are already in the printer such
as Commercial Press and SWOP Press.
■ Target device ICC profiles that get installed with the standard installation.
■ Target device ICC profiles that get installed with the optional software installation.
■ ICC Profiles created in a third-party profile creation software.
PhaserMatch and PhaserCal 4.0 User Guide
3-1
Device link profiles are used by PhaserMatch to create TekColor corrections. The TekColor
corrections can be sent to a Phaser printer or saved in the driver for the Phaser printer.
Note: When creating Phaser printer profiles using a third party ICC profile creation
application, you should make sure the print to be measured is made with no color correction
(Select None for the TekColor correction in the Phaser printer's PostScript driver). The print
Quality and Media Type selected from the Phaser printer’s PostScript driver will need to be
noted because these settings are required for use with the final custom TekColor correction
that you create.
Selecting a Phaser Printer Profile
To select a Phaser printer profile, click the Select Profile button under the heading Select a
Phaser Printer Profile, in the main Create Profile screen. If a new Phaser printer ICC profile
was created by a third party, the profile must be copied into the following folders:
■ Apple Macintosh OS X: Library, ColorSync, Profiles
■ Microsoft Windows 2000/XP: C:\WINNT\system32\spool\drivers\color
Selecting a Target Device Profile
To select a target device profile, click the Select Profile button under the heading Select a
Target Device Profile, in the main Create Profile.
Note: Target profiles describe the device that you want to emulate using your Phaser printer.
Two types of ICC profiles can be used as target profiles.
The ICC profiles most often used as target profiles specify CMYK colors for the device space.
In addition, applications, such as Adobe Photoshop can be configured to use CMYK colors. If
your files use this color mode, use your third party ICC profile creation tool to create CMYK
to Profile Connection Space (PCS) ICC profiles.
When working with RGB colors as part of Adobe Photoshop or applications, such as
Microsoft PowerPoint, use RGB to PCS ICC profiles.
Creating Custom TekColor Corrections
After selecting a Phaser printer profile and a target device profile, continue the process of
generating a new TekColor correction by clicking the Next button in the main Create Profile
screen. The Next button is not active until a Phaser printer profile and a target device profile
are selected in this screen.
PhaserMatch and PhaserCal 4.0 User Guide

Creating Custom TekColor Corrections
Device Link Profile Options Screen
The Device Link Profile Options screen has two check boxes. The check boxes are:
■ Pure Black Enhancement
■ Preserve Paper Color
Checking Pure Black Enhancement prevents colors specified by your prints as 100% black
from being converted into a combination of cyan, magenta, and yellow colors. When checked,
100% black prints using only black toner. Generally, this improves the sharpness of black fine
lines and text. This can reduce the darkness of large fills done with 100% black. This selection
affects both images and text.
Note: Pure Black Enhancement can make text appear sharper but it can also make text
appear lighter on some prints. When unchecked, PhaserMatch does undercolor color removal
on 100% CMY values only. It does not change equal CMY values of < 100%.
Checking Preserve Paper Color modifies the background colors of the prints. It tries to print
the background of the print in the color of the paper used when the target device swatches were
created.
Note: Preserve Paper Color can change the background color of the prints to make them
simulate the paper that was used when creating the target device profile but it can also change
the users' perceptions of other colors in the print.
Saving Device Link Profile Screen
The Save Device Link screen is used to a specify a detailed description and a short name for
the TekColor correction. When the Save Profile button is clicked, the TekColor correction is
saved as a device link profile.
Note: The printer driver uses the short name entered in this screen as the name of the
TekColor correction.
Sending a Custom TekColor Correction to the Printer Screen
Phaser 7760/7750 Printer
When you are creating a custom TekColor correction for a Phaser 7760 or Phaser 7750 printer,
the final screen in this process enables you to select the printer to which you want to send the
TekColor correction. This screen is not shown when using a Phaser 7700 printer. The Phaser
7760 and Phaser 7750 printer can store up to 10 custom TekColor corrections.
The Printers selection shows the Phaser 7760 and Phaser 7750 printers installed on your
computer and enables you to save to file. Selecting Save to File allows PhaserMatch to save
the custom TekColor correction as a printable PostScript file. The file then could be sent to
another system using the File Download functionality within CentreWare Internet Services to
send the file to a printer that is not installed on your computer.

Creating Custom TekColor Corrections
The Custom TekColor Corrections selection shows the 10 custom TekColor correction slots
that can be used to store the color corrections. When the printer selected is connected to the
computer using TCP/IP, PhaserMatch also shows the Short Name and other information about
the TekColor correction.
Target profiles can be either CMYK profiles or RGB profiles. Typically, applications, such as
Adobe Photoshop, use CMYK color mode. If you are using this color mode with your Phaser
printer, then the target profile used should be a CMYK target profile. Other applications, such
as Microsoft PowerPoint, use RGB colors. If you are printing from these applications use a
RGB target profile.
Note: You can use the Delete Profile button to delete profiles from your printer.
For more information about this screen, click the Help (?) button in the PhaserMatch
application.
Phaser 7700 Printer
PhaserMatch adds new color corrections to the printer driver when it is used with a
Phaser 7700 printer. The application updates the driver files to make the new TekColor custom
color corrections available in the driver on the computer where PhaserMatch is installed. There
is no method provided within PhaserMatch to update the drivers on remote computers so
PhaserMatch should be installed on each computer that is going to be using the new color
corrections. You can print CMYK color images from your driver using the new color
corrections. You must have color management turned off in your application when using
TekColor corrections.
A printer setup wizard should have helped you create a printer driver. Only this printer driver
contains the TekColor tab that allows you to select the link profiles you create using
PhaserMatch.

International Color
Consortium
Established in 1993 by eight industry vendors for the purpose of creating,
promoting, and encouraging the standardization and evolution of an open,
vendor-neutral, cross-platform color management system architecture
and components. The outcome of this co-operation was the development
of the ICC profile specification. The intent of the International Color
Consortium (R) profile format is to provide a cross-platform device profile
format. Device profiles can be used to translate color data created on one
device into another device's native color space. The acceptance of this
format by operating system vendors allows end users to transparently
move profiles and images with embedded profiles between different
operating systems. This permits tremendous flexibility to both users and
vendors. For example, it allows users to be sure that their image retains its
color fidelity when moved between systems and applications.
Furthermore, it allows a printer manufacturer to create a single profile for
multiple operating systems. (Quoted from the http://www.color.org)

Introduction to Color Management
Color management is based on color spaces. The range of colors, or gamut, perceived by the
human eye, captured on film, displayed on a computer monitor, and rendered by a printer vary
significantly. Each has its own color space, a mathematical means of describing its colors.
RGB is an additive color space that combines red, green, and blue light to create all other
colors. Monitors, digital cameras, and scanners typically use RGB colors. CMYK color, on the
other hand, is a subtractive color space using cyan, magenta, yellow, and black inks on paper to
absorb red, green, and blue light. The remaining reflected light is the color perceived by the
viewer.
Both RGB and CMYK color are device dependent color spaces; the colors they render depend
on the device that produces the colors. Additionally, converting an image from RGB to CMYK
compresses the colors into a smaller gamut. To complicate matters more, the CMYK color
space of one printer can vary significantly from the CMYK color space of another printer. As
the graphic below shows, the colors reproducible by different mediums can vary significantly.
1. Color visible to the human eye
2. Color film
3. Color monitor
4. Printer offset press on coated paper
5. Offset press on newsprint
The publishing industry has settled on a system of color management developed by the
International Color Consortium (ICC). ICC-based color management relies on two things:
device profiles called ICC profiles, which characterize how individual devices produce color,
and a color engine (also called a color matching module or CMM), which reads those profiles
and translates and corrects colors between devices.
ICC-based color management relies on a device independent color space. One of the common
color spaces specified for use is CIE L*a*b* (CIE Lab, LAB). This color space provides a link
between device dependent color spaces specific to various devices. LAB color space is based
on the way the human eye perceives color and is device-independent. A LAB color engine can
translate RGB, and CMYK values to and from LAB values. This translation acts as an
interpreter between the color spaces. ColorSync, a color-management software for the
Macintosh operating system, currently supports CMM color engines from vendors, such as
PhaserMatch and PhaserCal 4.0 User Guide
B-1
Heidelberg. These other vendors can use different algorithms to perform its color conversions.
Image Color Management System (ICM), a color management system for the Windows
operating system, also supports color engines from other vendors. When using PhaserMatch
with Macintosh, make sure the default CMM is the Apple CMM. When using PhaserMatch
with Windows, PhaserMatch is using its own CMM; the selection of CMM at the OS is not
used.
When you create an image using an application that uses ColorSync or ICM, a profile can be
embedded in the image file. The Phaser 7760, 7750, and 7700 printer work with applications
that produce CMYK and RGB colors and will ignore embedded profiles.
