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.
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.
Typical Uses of PhaserMatch Software Installing on Windows Systems 1. Insert the PhaserMatch or PhaserCal CD-ROM into your computer's CD-ROM drive. The CD-ROM automatically runs the installer. 2. Read the license agreement and click Accept to continue. Note: To install additional profiles, select Custom, and then select the profiles that you want to install. 3. Follow the prompts in the installer to finish the installation.
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.
Typical Uses of PhaserMatch Software The following diagram shows the color matching elements of the software and the flow of the software.
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.

. 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.
6. Measure the color swatches. Note: The instructions explaining how to manually measure the calibration data and create the needed data file are in section Spectrophotometer Calibration Data File on 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.
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. 2. 3. 4. Launch the PhaserMatch application. Click the Create Profile button in the main PhaserMatch screen.
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).
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.
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.
Printing with Custom TekColor Corrections Printing to a Phaser 7760 or Phaser 7750 Printer Macintosh OS X The TekColor corrections created by PhaserMatch work with applications that generate CMYK or RGB color values when printing. Computers with TCP/IP Connections to the Printer When using a computer with a TCP/IP connection to the printer, the driver lists the TekColor corrections using the short name of the correction. To select a custom TekColor correction: 1.

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.
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.
