Install a color profile
Color profiles are often installed when a device is added to your system. The accuracy of these profiles (often called
generic profiles or canned profiles) varies from manufacturer to manufacturer. You can also obtain device profiles from
your service provider, download profiles from the web, or create custom profiles using professional profiling
equipment.
• In Windows, right-click a profile and select Install Profile. Alternatively, copy the profiles into the
WINDOWS\system32\spool\drivers\color folder.
• In Mac OS, copy profiles into the /Library/ColorSync/Profiles folder or the
/Users/[username]/Library/ColorSync/Profiles folder.
After installing color profiles, be sure to restart Adobe applications.

Embed a color profile
You can embed a color profile in an object or an entire PDF. Acrobat attaches the appropriate profile, as specified in
the Convert Colors dialog box, to the selected color space in the PDF. For more information, see the color conversion
topics in Acrobat Help.
Changing the color profile for a document
There are very few situations that require you to change the color profile for a document. This is because your
application automatically assigns the color profile based on the settings you select in the Color Settings dialog box. The
only times you should manually change a color profile are when preparing a document for a different output
destination or correcting a policy behavior that you no longer want implemented in the document. Changing the
profile is recommended for advanced users only.
You can change the color profile for a document in the following ways:
• Assign a new profile. The color numbers in the document remain the same, but the new profile may dramatically
change the appearance of the colors as displayed on your monitor.
• Remove the profile so that the document is no longer color-managed.
• Convert the colors in the document to the color space of a different profile. The color numbers are shifted in an
effort to preserve the original color appearances.

About color working spaces
A working space is an intermediate color space used to define and edit color in Adobe applications. Each color model
has a working space profile associated with it. You can choose working space profiles in the Color Settings dialog box.
A working space profile acts as the source profile for newly created documents that use the associated color model. For
example, if Adobe RGB (1998) is the current RGB working space profile, each new RGB document that you create will
use colors within the Adobe RGB (1998) gamut. Working spaces also determine the appearance of colors in untagged
documents.
