PHOTOSHOP CS3 133 User Guide The setting you select determines which color working spaces are used by the application, what happens when you open and import files with embedded profiles, and how the color management system converts colors. To view a description of a setting, select the setting and then position the pointer over the setting name. The description appears at the bottom of the dialog box. Note: Acrobat color settings are a subset of those used in InDesign, Illustrator, and Photoshop. In certain situations, such as if your service provider supplies you with a custom output profile, you may need to customize specific options in the Color Settings dialog box. However, customizing is recommended for advanced users only. Note: If you work with more than one Adobe application, it is highly recommended that you synchronize your color settings across applications. (See "Synchronize color settings across Adobe applications" on page 132.)

Managing process and spot colors When color management is on, any color you apply or create within a color-managed Adobe application automatically uses a color profile that corresponds to the document. If you switch color modes, the color management system uses the appropriate profiles to translate the color to the new color model you choose. Keep in mind the following guidelines for working with process and spot colors: • Choose a CMYK working space that matches your CMYK output conditions to ensure that you can accurately define and view process colors.
