Patent ID: 8721824

Claim:
A production method of three-dimensional pattern, comprising: applying a first layer on a three-dimensional workpiece, wherein the three-dimensional workpiece bends at a place thereof; pressing a film onto the first layer by vacuum so that the film is impressed onto the first layer and a first three-dimensional pattern is formed on the first layer; curing the first layer by implementing a plurality of treatments thereon; and removing the film from the first layer, wherein the step of curing the first layer comprising: irradiating the first layer with a first UV to keep the shape of the first three-dimensional pattern when the first layer is impressed by the film; and irradiating the first layer with a second UV to fix the shape of the first three-dimensional pattern after the film is removed from the first layer, wherein the irradiating energy intensity of the second UV is higher than the irradiating energy intensity of the first UV.
