Anyone have experience with either of these films?
They're used in the commercial screen printing industry, come in waterproof
and non-water proof varieties, claim instant dry times and are designed for
Epson printers (dye inks) and rated to take ink and print at 4.0 logD
without losing detail (as is required in making screen masks). They seems to
cost slightly more than P-OHP. FastPositive will send you a free sample pack
(10 sheets) to try. Mine are in the mail.
