Thanks, Nikolay. ProofMaster support did tell me some time ago that the old device links from v3 would not work under v4, but I didn't specifically ask them about use of standard ICC Device Links. I will verify, but it doesn't look good. The best outcome for me would probably be if it were possible to just use Argyll device links to somehow update the original printer profile, if that is possible.
