Not to be a wet blanket, but according to Robert Harris, Tech prints can't be transferred satisfactorily because of their density & they best serve as color reference, not much else.
There are some dissenting views out there & you can take it up with Mr. Harris over at home theater forum, if you care to. ;-)
I'm not sure what he means by that, The Battle of Britain was transferred from an IB print as the 3 strip masters were in bad shape, and it looks great. Perhaps he was talking about striking a new neg from an IB print, or maybe on flying spot telecine systems.
It is more difficult to scan, and with older scanners you would get noisy shadows, but a current sensor and light source like I am using has no trouble. An automated system might struggle though.
