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.
