I'm just finishing up a nice custom vector based graphic I'm going to etch into my acrylic window. However, the acrylic is quite thick, and I don't believe placing a printed graphic behind the acrylic and then etching over it will be a good method, since my eye position will effect where the lines are drawn, and it's far too complex for any perspective inaccuracies. How can I get my image onto the surface of the acrylic and then etch it in perfect accuracy? Would t-shirt transfer sheets work on acrylic? I don't have a projector so that is out of the picture. Anyone have some advice?
