Re: photopolymer
Keith... is your mylar glossy? Remember what we figured out a while back... if you get newton rings with it, you can spray it with a fine coat of clear spray, like Krylon brand or artist fixatives. Don't use something that's made for outdoor use 'cause it will have UV blockers. That may keep you working until you get the Kreene. good luck, Susan On 5/3/07, Keith Taylor <taylordow@sprintmail.com> wrote: Susan, I pulled the frame apart and replaced some old foam rubber that sits under the ribbed bed of the frame with some nicer neoprene. The pressure remained the same throughout - at least on the dial, but who knows? While I wait for my roll of Kreene to arrive I tried using a thin (1mil) sheet of Mylar as you would with Kreene. No more contact problems - at least for now. I'll run some more tests tomorrow just to make sure and keep you updated. Thanks, Keith.

The glass actually still holds the vacuum. -- susan gravure blog at www.susanvossgravures.blogspot.com website www.dalyvoss.com
