Tiddler (and others):
Great work on the screen, and you've done quite a bit, and answered many questions that I had...
I am currently using a roll-down screen, and it works beautifully, but of course, I am thinking of ways to make it even better. I am also working on a DIY anamorphic lens project that shows a great deal of promise, so would want to maks my screen for constant height.
Anyway, I am using the back (fabric) side of a soft polymer fabric (vinyl?). It rolls up and down beautifully, and although it has a slight memory, any waves or wrinkles fall out almost immediately.
I am currently tweaking the screen, and added a 2 inch border around the entire screen. The border is a 2.5 inch wide black fabric (actually, the soft "loop" half of a velcro with adhesive on the back). While it works pretty well, I have found that any adhesive border (like tape, etc) on a roll-up screen actually creates waves. In other words, when I just have a simple fabric hanging, there are no waves, and the image falls pretty much as flat as possible.
So I put the border up, and sure enough, some waves were introduced. What I would like to do is paint a flat black border around the edge, but I really it to be a lot "blacker" than just flat black paint--a really good light absorber. I am thinking along the lines of how black velvet can appear. Any ideas?
Any ideas on additives that might be useful to add to the paint to really soak up stray light?
