Abstract

The invention relates to an apparatus and method of making a solid film. Viscous material (163) is input into a nip between a patterned roller (165) and a belt (167). The nip between the patterned roller (165) and belt (167) is facilitated by a compliant roller (169). Accordingly, a film may be produced that has discrete optical elements and a smooth backside.
