As I understand it, the order for print is master negative for the film (the one that is used to make the master interpositive), the master interpositive (that's used to make the master positive) or the master positive. As long as one has managed to escape vinegar sydrome, you can probably make a pretty decent print of the film.
After that you get workprints (a positive made without an interpositive), video editing screeners, etc. If all else fails, you bung whatever you got into whatever conversion/editing suit you have, do the best you can and put a note before the film letting the audience know that the master is missing and this is the best you can do picture wise.
One thing to be careful of, is that there are a number of cases of modern analog to digital film transfers stuffing up "day for night" shots by auto correcting them back to day. Awkward.
An example of the analogue vs digital - Paramount rereleased all of the original Star Trek films on BluRay, but they didn't re-release the "Director's cut" of The Motion Picture - because the special effects were all digitally done and would need to be completely redone for BluRay but the original film release required no additional work.
