Jalo, With regard to the BLF base+fog affecting exposure times, consider the
following:
Lightjet negs are digital images on positive photographic film (don't know
whose/which film) and the negs look like traditional B&W negs, except for
the black border. As I said, my use of these negs has produced my best
PT/PD prints. That being said, my exposures to prints via this film/neg are
in the neighborhood of 3.5 minutes.
That's the same exposure (+/-) that I am using for my test of BLF.

without pooling, so we're getting nice tones and good Dmax. We've done only
cyano, gum and polymer gravure so far, but the maximum blacks should be
enough also for processes that need higher contrast negatives.
