## 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.

## Claims

### Claim 1

A compliant pressure belt comprising an endless belt comprising at least one elastomeric layer and one metal layer, wherein the outside surface of said belt has a roughness average less than 50 nanometers and a hardness between 90 Shore A and 50 Shore D, wherein said at least one elastomeric layer comprises a first elastomeric layer and a second elastomeric layer; said first elastomeric layer and said second elastomeric layer differ in hardness; and said first elastomeric layer is toward the inside of the belt in relation to the second elastomeric layer.

### Claim 2 (depends on 1)

The compliant pressure belt of claim 1, wherein said at least one metal layer is on the outside of said belt.

### Claim 3 (depends on 2)

The compliant pressure belt of claim 2, comprising a metal layer on the inside of said belt.

### Claim 4 (depends on 1)

The compliant pressure belt of claim 1, wherein the first elastomeric layer has a greater hardness than the second elastomeric layer.

### Claim 5 (depends on 1)

The compliant pressure belt of claim 1, wherein the second elastomeric layer has a greater hardness than the first elastomeric layer.

### Claim 6 (depends on 1)

The compliant pressure belt of claim 1 wherein said at least one elastomeric layer comprises nanoclay particles in an amount of between 0.2 and 5 weight percentage in the layer having particles present.

### Claim 7 (depends on 1)

The compliant pressure belt of claim 1, wherein said belt has a circumference between 0.75 and 10 meters and a width between 0.5 and 2 meters.

### Claim 8 (depends on 1)

The compliant pressure belt of claim 1, wherein said at least one elastomeric layer is on the outside of said belt and said at least one elastomeric layer comprises between 1 and 10 percentage by weight of a polymer having a surface energy between 22 and 35 dynes per square centimeter.

### Claim 9 (depends on 1)

The compliant pressure belt of claim 1, wherein said belt is provided with timing protuberances on the inside of said belt.

### Claim 10 (depends on 1)

The compliant pressure belt of claim 1, wherein said metal layer is provided with a three-dimensionalpattern.

### Claim 11

A compliant pressure belt comprising an endless belt comprising at least one elastomeric layer and one metal layer, wherein the outside surface of said belt has a roughness average less than 50 nanometers and a hardness between 90 Shore A and 50 Shore D, wherein said at least one elastomeric layer comprises reinforcing fibers substantially oriented in one direction.
