I’m experimenting with an silicon foil (4mm transparent) to use as a compliant layer. As projection screen I use a Rosco foil. What I’ve read, many people apply the silicon (when pourring) directly o nthe acrylic. I’d also like to attach the silicon directly to the acrylic, as it otherwise is hard to attach without moving while touching. Anyway, this works and I get ok-blobs, when no projection layer is attached, when I add the Rosco screen, I don’t get any blobs! Am I missing something here?
Here’s some more information: I’m using Rosco samples at the moment and for the test I just mentioned I used the one of “negra retro 140” which I had used before to add latex, remove it, add it again and so on. I GUESS that might be the reason that I don’t get any blobs from that. I just tried a different, “unused” sample (color “azul retro 140") and now I get results, very dark blobs but at least something. Is there a way to get better blobs when using a rosco?
