Thatīs funny. I made dozens of digital negs using Epsonīs backlight film and
it did work just fine. Dan Burkholder in his book did recommend that film
too because of itī is not blocking UV...
Exposure time under my unit which was built according the layout Nadeau
gives in his books is 3-5min for pl/pt.
Concerning quality however I prefer negs put out by an imagesetter,
stochastic screening, 3600-4800dpi.
