Mind you, one can never go over the TIL built inside a CMYK output profile for as long as the image is in RGB space, only at the time of conversion does the R=G=B=0 gets mapped to whatever 300% or 320% or whatever TIL embodied in an output profile.
Which is why it seemed clear that the OP was talking about editing CMYK images…
This has nothing to do with gamut warning, Martin. In my humble knowledge.
Really? If you edit a CMYK image which has a TAC of 300% and make it 400% Photoshop’s Gamut Warning should show this shouldn’t it? If you set the soft proof profile to something similar — for example the BasICColor version of ISO Coated v2 (300) while your image is in the usual ICC version it will “kind of” do it. 310% TAC is outside of the limits of the profile. Why doesn’t Photoshop’s gamut warning show this? -- Martin Orpen Idea Digital Imaging Ltd
