Anti-counterfeiting hot-stamping method for two-dimensional codes

Abstract

The invention discloses an anti-counterfeiting hot-stamping method for two-dimensional codes. The anti-counterfeiting hot-stamping method comprises the following steps: step 1, designing bottom-layer anti-counterfeiting patterns and two-dimensional anti-counterfeiting patterns; step 2, electroplating the bottom-layer anti-counterfeiting patterns onto a nickel plate; step 3, selecting a base film; step 4, coating release coating on the base film; step 5, coating information-layer coating on the base film; step 6, stamping bottom-layer anti-counterfeiting patterns on the nickel plate onto the base film; step 7, coating a medium containing zinc sulfide on the base film; step 8, printing the two-dimensional anti-counterfeiting patterns onto the base film, wherein centers of the two-dimensional anti-counterfeiting patterns are superposed with those of the bottom-layer anti-counterfeiting patterns; step 9, plating aluminum on the base film; and step 10, coating an adhesive layer on the base film. According to the anti-counterfeiting hot-stamping method disclosed by the invention, the two-dimensional anti-counterfeiting patterns are stamped onto original package of products, so that beautiful and anti-counterfeiting effects of product appearances can be achieved, and the original package of the products is not changed.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code anti-counterfeiting, in particular to a two-dimensional code anti-counterfeiting hot stamping method. Background technique [0002] A two-dimensional code is a black and white graphic distributed in a two-dimensional direction with a specific geometric figure according to a certain rule to record data symbol information. Two-dimensional codes are becoming more and more recognized and accepted by the public, and anti-counterfeiting two-dimensional codes has gradually become a mainstream development trend. Two-dimensional code anti-counterfeiting uses two-dimensional code encryption technology to mark the product, and prints or labels the two-dimensional code on the product packaging. Users only need to decode and inspect the product through the designated two-dimensional code anti-counterfeiting system or mobile phone software. Authenticity, get detailed information. The two-dimensio...
