Single-layer embossed graphic micro-lens anti-counterfeiting label

Abstract

The invention relates to a micro-lens anti-counterfeit label, of a monolayer embossed pattern structure, formed by overlapping a micro-lens array pattern with a micro image-text array pattern. The micro-lens anti-counterfeit label of the monolayer embossed pattern structure does not show images under illumination of ordinary lamps or natural light, has anti-counterfeit concealment, and can show special micro image and text amplification and dynamic effect under illumination of point light sources. The micro-lens anti-counterfeit label is novel and unique in structure, the existing laser embossed holography equipment and process can be directly utilized for production, product forms are diversified, and application range is broad.

Description

technical field [0001] The invention relates to a microlens anti-counterfeit mark, in particular to a micro-lens anti-counterfeit mark with a single-layer embossed graphic structure formed by overlapping a micro-lens array and a micro-image-text array. Background technique [0002] At present, the anti-counterfeiting security thread with dynamic effect has been adopted on the banknotes of many countries, such as the 1,000 kroner banknote issued by Sweden in 2006, and the 50,000 won banknote issued by South Korea in 2010. In recent years, some companies, such as Hewlett-Packard Company of the United States, have also adopted anti-counterfeiting marks with dynamic effects on their products. In these anti-counterfeiting security threads and anti-counterfeiting marks, the enlarged image can produce continuous displacement according to the change of people's viewing angle. Their basic structure is a double-layer structure composed of a microconvex lens array layer and a micro gr...

Problems solved by technology

Its disadvantage is that the convex surface of the micro-convex lens increases the thickness of the anti-counterfeiting safety thread and anti-counterfeiting mark
