ICC profiles are binary files, and are opened automatically by Photoshop, the operating
system, printer drivers, and similar files. Profiles need to be installed in the correct location on your computer
for them to be available to image editing and other applications. These locations
Mac OS X:
Storing profiles in /Library/ColorSync/Profiles
allows all users to use them. An alternative area, for users without Admin privileges, is /Users/<username>/Library/ColorSync/Profiles. Profiles stored here are available only to the current user. The ColorSync Utility gives access to the details of individual profiles, shows gamut plots, can rename profiles, validates profile structure, among other useful tasks.
- OSX 10.7.3 (Lion) and above: The system profile folder is hidden by default. Storing profiles in this folder is possible, but requires following the steps described here.
- OSX 10.9 (Mavericks) and above: Depending on the printer profile, individual system configuration, and perhaps the phase of the moon, Adobe products (e.g. Photoshop, Lightroom - and particularly the Creative Cloud or CS6 versions) sometimes refuse to recognize profiles installed outside an Adobe-specific location. If a printer profile installed to either the system or per-user folder does not show up from within an Adobe product, move the profile to /Library/Application Support/Adobe/Color/Profiles/Recommended. A reboot may be required for the profile to be visible from within the Adobe application.
Windows (all versions):
- Microsoft has a Control Panel Applet that emulates some of the functionality of Apple's ColorSync utility. It allows easy installation and removal of profiles, editing of internal and external names, viewing 3-D gamut plots, comparing two different profiles, and much more.
- If you do not use the Color Applet, the easiest way to install a profile in Windows XP is to right click on the profile in Windows Explorer and select "install
profile". Windows copies the profile to the correct directory automatically.
- Important note: If you are replacing a profile in Windows XP, the above shortcut
does not work. The profiles must be manually copied to the correct directory for the original
profile to be replaced.
