22-5 PostScript applicationsPostScript applicationsMost applications used for illustration, pixel editing, and page layout can create thePostScript information they send to a PostScript printer or save in PostScript files.Illustrator, Photoshop, PageMaker, QuarkXPress, and Macromedia FreeHand areall PostScript applications.PostScript applications work with color in many different ways. Most allow you tochoose process colors (by entering percentages for cyan, magenta, yellow, and black),as well as named colors from a spot color system, such as PANTONE. When youprint composites, these applications send process-color equivalents for named spotcolors to the Color Server. In some applications, you can also choose colors using theRGB, HSB, HSL, or other color models.Generally, PostScript applications send color information to the Color Server asCMYK data. An exception to this is an RGB image placed in the document, which issent directly to the Color Server (unless you specify special color management settingsin the application.) In addition, some PostScript applications that allow you to definecolors in RGB or other color models can also send data to the Color Server in thosecolor spaces.Color controls in PostScript applications are typically designed for printing on anoffset press, and some adjustments are required for printing to the Color Server.Displayed versions of colors you choose in these applications may not matchColor Server output exactly, and named colors may not print accurately on theColor Server, since these colors typically require custom inks.
