Abstract

The invention discloses a process for making anti-counterfeiting paper by using base paper. First, the transparent laser film is coated with high-transparency UV varnish, then compounded with the base paper, cured under a UV lamp, dried, and the transparent laser film is peeled off to obtain a transparent High-brightness laser cardboard, aluminum layer and varnish layer, and then apply a humidifying layer on the back, and cut to get the finished product. The present invention uses base paper and transparent high-brightness laser cardboard to compound, quickly replicates the laser holographic pattern, and then restores it on the aluminum to obtain the laser cardboard. The whole process is simple, fast, short in process and low in production cost.

Description

technical field [0001] The invention relates to a process for making anti-counterfeit paper, in particular to a process for making anti-counterfeit paper by using base paper. Background technique [0002] With the development of anti-counterfeiting technology, it has become a considerable and fast-growing industry. There are various anti-counterfeiting designs on the market. [0003] Anti-counterfeiting paper is an important application of anti-counterfeiting technology. Anti-counterfeiting paper is widely used in ticket paper, bond paper, passport paper, ticket paper, certificate paper, etc. [0004] The traditional production process of anti-counterfeiting paper is through film coating, then die-press aluminum plating to become laser transfer film and then dry-wet lamination with paper. The product process is complex, time-consuming, high production cost, and the anti-counterfeiting effect of the prepared anti-counterfeiting paper is poor. , easily counterfeited. Conten...
