right.. that's mylar.

Have you tried printing shops? It could be pretty expensive, but
even Kinko's has large plotters w/ rolls of clear mylar.

You would have to scan in the original and then have it printed out.

I came across this same problem w/ some lithography work I was doing,
in needing large black and white transparencies. I would try talking to
printing shops or sign-making shops..

You might also talk to a local fine arts department at your nearest
university. I know our dept was trying to aquire a plotter that could
handle 3'rolls of mylar.

Actually, you might also talk to some scientific departments at
the university. Here, a couple of environmental physics departments have
these large color plotters for making posters for conferences and they
charge $30 per print. So, if you found a sheet of mylar of the right
size, atleast here, I suspect ,you would be allowed to use the printer.
You might check for similar in your area.

Good luck
