when I researched new LCC materials for a larger LCC plate, I sent sets of my first 2 sample materials to Guy, Terry and Bob to test along with me. Those initial pieces were fine, but didn't work any better/different than the CI LCC plate. I then found the material I made for the workshop group, and sent Guy, Terry and Bob each one or two of them. This final material was easy to use and in most cases generates an excellent LCC with a 1 or 2-stop exposure bump. I think by then Guy was tired of trying them, was doing fine with teh CI plate and so tossed them away. And now he needs one :ROTFL:
Anyway, for those interested the material is 40% transmissive translucent white acrylic, and can be found at TAP plastics. They will cut it to any size you need up to 4 by 8 feet, so I am sure Guy can get exactly what he wants
