<p>A method and apparatus (20) are provided for replicating a light shaping surface structure on a laminated surface of a relatively rigid substrate (ST). More specifically, after the substrate (ST) is mounted on a table (24) and a layer of epoxy is deposited between the substrate and a submaster (SU) to produce a layered structure, the layered structure is automatically compressed in a nip formed between the table (24) and an outer surface of a rotating impression roller (26), thereby replicating the surface structure in the epoxy layer. The epoxy is then cured, and the submaster (SU) is separated from the substrate (ST) to leave a laminated structure having the light shaping surface structure on a surface thereof. Preferably, the submaster is wrapped around the impression roller, and the impression roller (26) is rotated while the table (24) is reciprocated linearly.</p> |
