Changing the color profile of a document
In some cases you may want to convert a document's colors to a different color profile, tag a document with a different color profile without making color conversions, or remove the profile from a document altogether. For example, you may want to prepare the document for a different output destination, or you may want to correct a policy behavior that you no longer want implemented on the document. Photoshop has the Assign Profile and the Convert to Profile commands, which let you remove, reassign, or change profiles in a document. The Assign Profile and Convert to Profile commands are recommended for advanced users only. When using the Assign Profile command, you may see a shift in color appearance as color numbers are mapped directly to the new profile space. Convert to Profile, however, shifts color numbers before mapping them to the new profile space, in an effort to preserve the original color appearances.
To reassign or discard the profile of a document: - Choose Image > Mode > Assign Profile.
- Select one of the following:
- Don't Color Manage This Document to remove the profile from a tagged document. Select this option only if you are sure that you want the document to become untagged.
- Working color mode: working space to tag the document with the current working space profile. For more information about working spaces, see About working spaces.
- Profile to reassign a different profile to a tagged document. Choose the desired profile from the menu. Photoshop tags the document with the new profile without converting colors to the profile space. This may dramatically change the appearance of the colors as displayed on your monitor.
- To preview the effects of the new profile assignment in the document, select Preview.
To convert colors in a document to another profile: - Choose Image > Mode > Convert to Profile.
- Under Destination Space, choose the color profile to which you want to convert the document's colors. The document will be converted to and tagged with this new profile.
- Under Conversion Options, specify a color management engine, a rendering intent, and black point and dither options. For more information on conversion options, see Customizing advanced color management settings.
- To flatten all layers of the document onto a single layer upon conversion, select Flatten Image.
- To preview the effects of the conversion in the document, select Preview. This preview becomes more accurate if you select Flatten Image.
