A patterned roller, and a method of making the patterned roller, is provided. A patterned roller may be made by first forming a first mold having a negative pattern in a flat surface by etching. A second mold is formed having a positive pattern, by pouring a first curable material into the first mold and processing. The patterned roller having the negative pattern is formed by coating a roller with a layer of a second curable material, pre-curing the second curable material, and rolling the roller over the second mold. The second curable material is then cured. A metal coating may be applied after curing any of the materials to reduce sticking in subsequent steps. The patterned roller may be used to create a pattern of microlenses in a third curable material by rolling. |
