ICC Digital Lab Profiles
Alkit makes its ICC Profiles available for those wishing to Soft-Proof or to provide the ability to incorporate precise color corrections, prior to output by our lab. Our staff is available to assist you with the installation and use of our ICC Profiles. After downloading, install the profile as follows:

After downloading the profile, you need to save it in a location that depends on what operating system you are using. The profile files work equally well on Windows or Mac computers. Save the profile to a handy location. You need to install profiles before using them. Note that the profiles are binary files – they do not contain readily readable information and can not be opened directly by most applications. Image editing applications such as Photoshop and color printer drivers are equipped to use them.
These locations are:
- Mac OS X (all versions): If your account has administrative privileges, 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 — any 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, and validates profile structure among other useful tasks.
In OSX 10.7 (Lion), Apple hides the user ICC profile folder of /Users/<username>/Library/ColoySync/Profiles by default (in fact, the entire library folder is hidden). Storing profiles in this location is still possible, but requires making the folder visibile.
To make the per-user ICC profile folder visible permanently, follow the steps below:
- Launch a terminal:
- Applications → Utilities → Terminal
- From the Terminal window, type:
- chflags nohidden ~/Library
- If prompted, enter the system administrator password.
Note that some monitor and printer profiling applications bomb on Lion because the Library folder appears not to exist. If you find this to be the case, unhiding the Library using the steps above is necessary.
Profiles can now be copied into the profile library normally. Note that some applications may not see recently installed ICC profiles until the system is restarted.
If temporary access is required to the Library, for example to copy a single profile to it, and you do not want to permanently unhide the folder, use one of the techniques below:
- Option-Go: Click the Go menu and hold down the Option key. The user's Library shows as a selection in the menu, and clicking it brings you to the correct folder. There is no hot-key combination to open the folder directly, so mousing and clicking is required.
- Go to Folder: Select Go to Folder under the Finder's Go menu or simply press Shift-Option-G from within the Finder. Type ~/Library as the Go-to location, then click Go. Option #1 is easier.
- Launch a terminal:
- Windows 7, 2008, Vista, and XP: \Windows\system32\spool\drivers\color
- The easiest way to install a profile in Windows Windows 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, the above shortcut does not work. The profiles must be manually copied to the correct directory for the original profile to be replaced. Microsoft has listed this as a bug since Windows 98.
- Windows 7 and Vista have a Control Panel applet that allows selecting default profiles for devices and manually installing profiles that are not already in the system profile directory. The functionality is limited, and a right-click automatic install or manually copying the profile to the system profile directory is much easier.
- Windows XP 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. This applet works on XP only; newer operating systems are not supported.
