When I was thinking about subbing , two concepts came to mind.
First , etching the polyester with acid, I dont know its feasibility , may be it works.
Second , is to order a steel plate from CNC shop which subbed with acids or fire and pressing it on to polyester like a hot press. Remember , there are tremandous amout of different textures applied on to steel after steel mold machined and there are too many shops which can do the subbing on to steel.
may be subbing steel plate positive could be difficult but high heat epoxy can transfer the texture patten on its surface from steel and than press on to the polyester film with ir lamp help.
