Alt processes need a higher Dmax and contrast scale so it may be OK.

Yes, that was the question. How does a direct-positive process compare to a double-copying process as far as quality (image gradation, sharpness, grain) goes?

In the good old days, Kodak had a positive film like that, for making enlarged negatives without an interpositive.

There is such film, made by Agfa; available in sheets and wide long rolls.

Not the Agfa (as far as I know) but there is this stuff as well.

The specialist copy films worked best whether the Colour Duping film, Inter-neg or B&W direct positive. Some Alt process users use reversal processing to eliminate two copy steps. Ed Buffalo has an article on Unblinkingeye.
Most now are making Digital negatives, plenty of threads on HybridPhoto,

I've been using APHS. It's a bear. I would bet the Ultrafine is APHS or the replacement.

Except that the APHS is a negative film, isn't it? The Ultrafine is a direct positive dupe film.
