The following sections describe the options available from the ColorWise color
management system and explains how to customize the color settings for your
particular needs. They provide descriptions of the preset ColorWise default settings
and cover additional options for users who need to customize ColorWise.
For information on PostScript Level 2 or 3 printer drivers, see page 1-16. The section
also contains information on the capabilities of printer drivers and instructions for

NOTE: Many of the color management options described in this chapter are only
