Highly Efficient Nano-structure Pattern Transferring Technology for Anti-counterfeiting

Nano-structure patterns on optical products for various uses, such as anti-counterfeiting features, are becoming more and more popular. However, traditional methods for producing nano-structure patterns are not fully able to meet market needs. They either have long manufacturing cycles which result in low productivity, or incur high production cost which increases product prices. Our invention provides a solution characterized by a short manufacturing cycle and low production cost for producing nano-structure patterns.

The device ejects a fixed amount of UV glue on the surface of the target object, over which a mold with a specially designed nanoscale-structure pattern is placed. By applying UV light, the UV glue is solidified and the nano-structure pattern is permanently imprinted on the surface. The solution dramatically lowers the production cost.
