The system automatically selects the proofer profile based on the media type that you choose for a given hot folder or virtual printer. Although you can use any other profile that you like, keep in mind that these profiles are designed to work specifically with Kodak proofer inks and media. In addition, if you don't use the default profile, you cannot output Certified proofs.
Note: If the desired ICC profile is not in the list, you may have to import it.
