Where do I need to put ICC or ICM profiles to use them with my Epson printer or scanner?

ICC or ICM profiles must be placed in certain folders in order for them to be accessible to your applications, and the location of these folders is different on each operating system. The most common locations are as follows:

Windows 10,Windows 8 and Windows 7:
  • C:\WINDOWS\system32\spool\drivers\color
macOS/Mac OS X
  • macOS hard drive, then: Library\ColorSync\Profiles
Mac OS 9.X
  • Mac hard drive, then: System Folder\ColorSync Profiles

Some applications may require the files to be in ICM format (for a PC) or ICC format (for a Mac). You can rename the files to give them the required extension (.icm or .icc).
