Hmmm, I've never heard of that.
I'm not sure how that would work, because it's a complete bag, so it would encompass both sides of the screen then......
You can use a board with weight or a compression lid, depending on your exposure unit.
I have a compression lid in conjunction with a fitted piece of foam rubber with my exposure unit (from Ryonet, 8 fluor.) and it works great. I do lots of halftone jobs with lots of detail and get great results.
