Synchronize color settings across Adobe applications
If you use Adobe Creative Suite, you can use Adobe Bridge to automatically synchronize color settings across applications. This synchronization ensures that colors look the same in all color-managed Adobe applications.
If color settings are not synchronized, a warning message appears at the top of the Color Settings dialog box in each application. Adobe recommends that you synchronize color settings before you work with new or existing documents.
Edit > Creative SuiteColor Settings Select a color setting from the list, and click Apply. If none of the default settings meet your requirements, select
Show Expanded List Of Color Setting Files to view additional settings. To install a custom settings file, such as a file you received from a print service provider, click
Show Saved Color Settings Files .
