If you can get some polyester translucent paper, you can use a drop of water. Works great.

I am considering making a vacuum frame to use for the UV exposure method.
Has anyone made or own a vacuum frame that they can share their thoughts on?
I am unable to find any pictures or information of PCB frames made by others
for our purposes. Does anyone have any suggestions for materials like
plastic covering (dry cleaner bags UV transparent?) or the porous material
for allowing the vacuum to flow under the board?

I'm using a Samsung ML-2525. Works well, just have to make sure you have it
set to the darkest settings. I've dedicated this printer for PCB's in the
lab.
Have a look at

Also, drop Frank an e-mail at mail@...

product.
