Abstract
A stereoscopic pattern apparatus includes a base roller and a retrieving roller, a fine pattern hardening roller, an ink inserting roller and a convex pattern hardening roller. The base roller and the retrieving roller respectively provide and retrieve a base film. The fine pattern hardening roller is disposed between the base and retrieving rollers, and forms a lower hardening layer on the base film. A fine pattern is formed on the lower hardening layer. The ink inserting roller is disposed between the fine pattern hardening roller and the retrieving roller, and inserts an ink into the fine pattern. The convex pattern hardening roller is disposed between the ink inserting roller and the retrieving roller, and forms an upper hardening layer on the lower hardening layer. A convex lens is uniformly formed on the upper hardening layer.
