Thanks for responding! I have been disappointed that no one else has picked
up on the thread. If you could share, I am curious about your experience
with scanning.

That's encouraging.

You mean an optically clear enough film? Or one that is compatible with your
inkset? I work at a sign shop and today contacted one of our distributors to
look for some clear film to print on a large format inkjet printer. To my
surprise, the tech guy was aware of using inkjet negs to make contact
prints, and suggested an "optically clear film" from a company called Rexam
(we use other products by them, and they are excellent). So I am excited
about that. $100USA for a 24" x 150ft. roll. Not too bad.

Something that I am wondering about using inkjet negs, is the fading of the
inks. The large format printer I have access to can use both dye-based &
pigment-based inks. The pigment inks are UV-resistant, and I figured that
that would be more appropriate (duh....). However, he told me that you
actually get more d-max with the dye-based, and suggested that the pigment
would be too thin. In addition, he said that the 4mil film that he sold is
incompatible with pigment-based inks. Maybe someone here has some info. on
dye vs. pigment inks.

Nick, a company I subcontract work to does Lightjet prints for $13.00 USA a
square foot! If I get more than 3 square feet, that goes to $10. :) I think
I might be able to get it slightly lower if I put in a bulk order. This is
for the clear film, BTW; not paper (which is $11 to $8.50 respectively,
although not Fuji Crystal).

Hearing you say that Lightjet is viable is music to my ears because
imagesetter negs seemed _way_ too expensive, and I had dismissed inkjet for
the visible dot pattern on many large format printers (epson desktops are
excellent, but I want 16x20 & larger prints). This is changing of course,
but lightjet transparencies are the closest digital method to actual
photographic negs that I can see.

Could you give me an idea of how you prepped your digital files for lighjet?
Have you done any multi-neg gum prints by chance? I have a few shots I
wanted to experiment making 4-color seps.

Thanks again for responding. I'd be happy to get you a deal on lighjet
prints if you'd like. BTW, another company does Lambda prints, which I
understand is very similar technology, but I'm not clear on if one is of
higher quality than the other. Prices from them are very similar.
