Yes. Print-Tool encodes a null-set profile to get around the “no color management” issues with OS X and ACPU does something different that works better.
BTW, I am updating the Piezography ICC Profile tool in the next 48hrs or so. It works well, but I’m coming out with some colorport targets.
Just FYI. Piezography Professional Edition has updated to 1.4 with the updated ICC targets.
