Abstract:
A method of replicating a light shaping surface structure comprising:(A) positioning a layered structure in a nip formed between an outer surface of an impression roller and a table, said layered structure including 1) a relatively rigid substrate which is supported on said table, 2) a submaster which has said surface structure on a surface thereof which faces toward said table, and 3) a layer of epoxy disposed between said substrate and said submaster;(B) automatically compressing said layered structure in said nip so as to replicate said surface structure on said layer of epoxy while moving at least one of said table and said roller linearly relatively to the other of the table and said roller so as to prevent relative sliding movement between said substrate and said submaster;(C) curing said layer of epoxy; and(D) separating said submaster from said substrate to leave a substrate/epoxy laminate having said surface structure on a surface thereof.
