One should be able to convert using any of these profiles and then assign one of the other profiles and have no/very little colour rendering difference. What is the same is that they all use the same underlying measurement characterisation data (either F39 or F39L). Different software, different algorithms etc. Just like ISO Coated v2 300% (ECI) is not the same as ISO Coated v2 (ECI) which is 320%.Īgreed, just like the very good BasICColor profiles and the VIGC profile variants and the Kodak F39L and others are not the same profile. I know ISO Coated v2 (ECI) is built on the older FOGRA39 specification, but it's not the same profile.
