Oops – I meant
to say: How Thick is the vinyl cloth?

Hi Mark –
That sounds great – we have been using matt boards with a
piece of masking plastic on top but this sounds like it will create a better
vacuum seal.
How this is the "cloth" that you are using?

David,
On my NUARC, I use a piece of
thin vinyl "cloth" I got at the fabric store — the kind used
for upholstering. It has a very fine texture to it that helps let air
escape when you draw down the vacuum. It provides enough buffer so the
texture of the vacuum bladder does not print out.

I'm doing photopolymer

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
