Embed a color profile
To embed a color profile in a document you created in Illustrator, InDesign, or Photoshop, you must save or export
the document in a format that supports ICC profiles.
1 Save or export the document in one of the following file formats: Adobe PDF, PSD (Photoshop), AI (Illustrator),
INDD (InDesign), JPEG, Photoshop EPS, Large Document Format, or TIFF.
2 Select the option for embedding ICC profiles. The exact name and location of this option varies between applica
tions. Search Adobe Help for additional instructions.
Embed a color profile (Acrobat)
You can embed a color profile in an object or an entire PDF. Acrobat attaches the appropriate profile, as specified in
the Destination Space area of the Convert Colors dialog box, to the selected color space in the PDF. For more infor
mation, see the color conversion topics in Complete 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 appli
cation 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 desti
nation 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.
• (Acrobat, Photoshop and InDesign) 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.
Assign or remove a color profile (Illustrator, Photoshop)
1 Choose Edit > Assign Profile.
2 Select an option, and click OK:
Don’t Color Manage This Document
Removes the existing profile from the document. Select this option only if you
are sure that you do not want to color-manage the document. After you remove the profile from a document, the
appearance of colors is defined by the application’s working space profiles.
Working [color model: working space]

Discard (Use Current Working Space)
Removes the existing profile from the document. Select this option only if you
are sure that you do not want to color-manage the document. After you remove the profile from a document, the
appearance of colors is defined by the application’s working space profiles, and you can no longer embed a profile in
the document.

Assign Profile
Lets you select a different profile. The application assigns the new profile to the document without

3 Choose a rendering intent for each type of graphic in your document. For each graphic type, you can choose one
of the four standard intents, or the Use Color Settings Intent, which uses the rendering intent currently specified in
the Color Settings dialog box. For more information on rendering intents, search in Help.
The graphic types include the following:
Solid Color Intent
Sets the rendering intent for all vector art (solid areas of color) in InDesign native objects.
Default Image Intent
Sets the default rendering intent for bitmap images placed in InDesign. You can still override
this setting on an image-by-image basis.
After-Blending Intent
Sets the rendering intent to the proofing or final color space for colors that result from trans
parency interactions on the page. Use this option when your document includes transparent objects.
4 To preview the effects of the new profile assignment in the document, select Preview, and then click OK.

Customize color settings
For most color-managed workflows, it is best to use a preset color setting that has been tested by Adobe Systems.
Changing specific options is recommended only if you are knowledgeable about color management and very
confident about the changes you make.
After you customize options, you can save them as a preset. Saving color settings ensures that you can reuse them
and share them with other users or applications.
• To save color settings as a preset, click Save in the Color Settings dialog box. To ensure that the application displays
the setting name in the Color Settings dialog box, save the file in the default location. If you save the file to a
different location, you must load the file before you can select the setting.
• To load a color settings preset that’s not saved in the standard location, click Load in the Color Settings dialog box,
select the file you want to load, and click Open.
Note:
In Acrobat, you cannot save customized color settings. To share customized color settings with Acrobat, you must
create the file in InDesign, Illustrator, or Photoshop, and then save it in the default Settings folder. It will then be available
in the Color Management category of the Preferences dialog box. You can also add settings manually to the default
Settings folder.
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.
Aworking 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.
If you open a document embedded with a color profile that doesn’t match the working space profile, the application
uses a color management policy to determine how to handle the color data. In most cases, the default policy is to
preserve the embedded profile.
