I’m not understanding at all how exceeding the TAC is an “out-of-gamut” issue. It’s not OoG, it’s more of a print quality issue.
In the case of certain digital presses, maximum density or min L* is reached at 100% TAC (100% black only)……it would be a good trick to have a plug-in report that a 200% secondary overprint is NOT exceeding TAC while any amount of CMY added to 100K would exceed the TAC. :-)
