Hi David,
I use a thin, stiff sheet of black plastic with a dull finish on one
side and a rough finish on the other. I forget what it's called
exactly, but it is available from plastic and plexiglass supply
houses.
I have only had an issue with air not escaping thoroughly when using a
plate as wide as the bed (40"). Vinyl fabric may work better in that
case, so I should try it next time I shoot large plates.
I usually want something there to avoid having the plastic bumps from
the blanket on the vacuum bed mar my aquatint screens.
Thanks for the question.

fall apart, shedding tiny little pieces. I use a piece of soft vinyl
available from crafts stores. Flexible, easy to keep clean and cheap.

I'm doing photopolymer process
with Toyobo plates and also with ImagOn film. And I'm using a NuArc
exposure unit for exposing my plates. The person who set up the unit in
our studio but a piece of pressboard on the bed of the unit, so it lays
under your plate and film. When I say pressboard, I mean a stiff
"paper" (like a thin matboard) that they use in stiff mailing envelops
or that you might find when you unwrap a new dress shirt--sort of
cardboard without the corrugation.
I'm wondering if this is the best material to use on the bed of the
unit, or would it be better to use something else like maybe sheets of
print paper, or maybe nothing at all?
Thanks, David
