This chapter provides guidelines for using applications that have the ability to write 
their own 

, such as some page layout, illustration, and pixel-editing 

applications. For information about using specific applications, see 

Most applications used for illustration, 

 editing, and page layout can create the 

PostScript information they send to a PostScript printer or save in PostScript files. 
Illustrator, Photoshop, PageMaker, QuarkXPress, and Macromedia FreeHand are 
all PostScript applications.

PostScript applications work with color in many different ways. Most allow you to 
choose 

 (by entering percentages for cyan, magenta, yellow, and black), 

as well as 

 from a spot color system, such as PANTONE. When you 

print composites, these applications send process-color equivalents for named 

 to the Color Server. In some applications, you can also choose colors using the 

, or other color models.

Generally, PostScript applications send color information to the Color Server as 
CMYK data. An exception to this is an RGB image placed in a document, which is 
sent directly to the Color Server (unless you specify special color management settings 
in the application). In addition, some PostScript applications that allow you to define 
colors in RGB or other color models also send data to the Color Server in those color 
spaces.

Color controls in PostScript applications are typically designed for printing on an 
offset press, and some adjustments are required for printing to the Color Server. 
Displayed versions of colors you choose in these applications may not match Color 
Server output exactly, and named colors may not print accurately on the Color Server, 
since these colors typically require custom inks. 

Chapter 4:
Managing Color 
in PostScript 
Applications

With PostScript applications, you can work with colors created with any of the color 
models supported by the application. All PostScript applications support CMYK; 
some also support RGB and other color models based on monitor display values. 
PostScript applications also allow you to choose named colors using one or more color 
libraries, such as PANTONE (see 

Your Color Server user software includes several color reference pages (see 

). 

By choosing colors from these reference pages, you ensure that you get the same color 
from your device. For best results, calibrate the Color Server before printing the 
reference pages. 

We highly recommend that you use swatch color matching to ensure predictable 

color printing results with the Color Server or match your Color Server output to 
colors produced by other printers. 

Swatch color matching does not match monitor colors to printed colors. 

For this, you must use a color management system and calibrate your monitor.

Use the CMYK Color Reference included with your Color Server user software to see 
how various cyan, magenta, yellow, and black combinations look when printed on 
your printer.

To print the CMYK Color Reference, download the file to the Color Server. 
The printed pages display groups of color patches in graduated combinations of 
yellow, magenta, and cyan, and smaller patches that include 25%, 50%, and 75% 
black. Refer to these pages to pick colors and specify process color values in your 
application. For the location of the file on the User Software CD, see the 

.

Use this reference (Process Simulation of PANTONE Solid Coated Colors) included 
with your Color Server user software to help ensure predictable results with colors 
chosen from the PANTONE color library. 

The information printed by this reference depends on the Spot Color Matching 
setting. 

•

—Prints swatches that simulate the spot color with the 

closest equivalent available using the CMYK toners of the copier/printer connected 
to the Color Server. The equivalent PANTONE color name/number is printed 
below each swatch.

•

—Prints swatches of the CMYK equivalents of PANTONE 

colors as defined by PANTONE. (These are the same CMYK values defined in 
applications that include PANTONE libraries.) The CMYK values used to produce 
the color, as well as the PANTONE color name/number, are printed below 
each swatch.

To print the reference, download the file to the Color Server. For the location of the 
file on the User Software CD, see the 

. If the default 

Spot Color Matching setting on the Color Server is not the setting you want to use for 
printing the PANTONE colors, download the file to the Hold queue, and then 
override the Spot Color Matching setting using a job management utility, such as 
Command WorkStation (see the
