6. Saving the Profile


Previous Section Previous Page Contents Next Page Next Section

Although other pages of this User Guide are written to display information relating to just one platform implementation of inCamera (either Windows or Macintosh), this page will describe all platforms. The reason is that some users may wish to create the ICC profiles on one platform and then use them on a different platform. Such a "cross-platform" user must know the rules about ICC profiles on more than one platform, for example, where ICC profiles should be placed, what the file names should be, and so forth. If you are working on only one platform, you may safely read just that section below.

A General Note on Profile Overwriting: If you overwrite an existing profile when you save a new profile, Photoshop may not be able to use it properly until you restart Photoshop. This is apparently due to profile caching performed by Photoshop. You will not have this problem if you save each new profile under a unique name, in which case Photoshop may make use of it immediately, without restarting.


Windows

Profile Locations

ICC profiles are located in these standard places on Windows XP:

Location Purpose
C:\WINDOWS\SYSTEM32\COLOR\ Photoshop 5 looks here.
C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\COLOR\ Photoshop 6 and later look here.

Profile Naming

ICC profiles must have the proper file name extension in order to work on Windows. Two suitable extensions are: ".icc" and ".icm".


Macintosh OS X

Profile Locations

ICC profiles are located in these standard places on OS X:

Location Purpose
/System/Library/ColorSync/Profiles/ This is where ColorSync stores profiles it uses internally for critical operations, should others be mistakenly lost or damaged. This folder is locked and protected, which normally prevents you from placing ICC profiles here.
/Library/ColorSync/Profiles/ This is the recommended place for applications (like inCamera) to store profiles, and therefore is the default.
/Network/Library/ColorSync/Profiles/ If you are in a network environment and your network administrator has stored profiles on the network for network devices, this is where they will be located.
~/Library/ColorSync/Profiles/ Users can store their own personal profiles in their home directory.

Profile Naming

There are no naming restrictions for ICC profiles. A file name extension is not needed, but if you choose to use one, Apple recommends ".icc". ICC profiles do not need creator or file type signatures, but if you choose to use them, use 'sync' for the creator signature and 'prof' for the file type signature.


Macintosh OS 9

Profile Locations

ICC profiles are located in this standard place on OS 9:

Location Purpose
System Folder/ColorSync Profiles/ This is the only standard place that ColorSync looks to find ICC profiles.

Profile Naming

There are no naming restrictions for ICC profiles. A file name extension is not needed, but if you choose to use one, Apple recommends ".icc". ICC profile files must have 'sync' for the creator signature and 'prof' for the file type signature, which inCamera automatically provides. However, if you have transferred an ICC profile from a Windows computer, it will not have these signature assignments. In this case, you may use Apple's Drop•ColorSyncProfile utility to set the proper file signatures. It is available here (6K).
