Method for realizing two-dimension code-variable printing on optical variable device (OVD) hot stamping foil

Abstract

The invention discloses a method for realizing two-dimension code-variable printing on optical variable device (OVD) hot stamping foil. In order to solve the problems that operating personnel and the environment can be harmed because a corrosive aluminum washing agent needs to be used when aluminum is washed to prepare aluminum-plated hot stamping foil, an anti-counterfeiting mark of laser ablation and an anti-counterfeiting function are single, process equipment is complicated, the production efficiency is low, and the equipment investment is great in the prior art, the invention provides the novel two-dimension code OVD location hot stamping foil with a compound anti-counterfeiting function and a production method for the hot stamping foil, wherein the novel two-dimension code OVD location hot stamping foil is obtained through preforming corresponding printing treatment and aluminum washing treatment on OVD location hot stamping foil by organically combining a manufacturing process for the OVD location hot stamping foil with the accurate aluminum washing technology and the two-dimension code-variable printing technology. According to the adopted technical scheme, the method for realizing the two-dimension code-variable printing on the OVD hot stamping foil comprises the following steps of: 1, release layer and information layer coating, mould pressing, gloss oil printing, aluminum-washing printing ink location printing, vacuum aluminum plating, local aluminum washing, location two-dimension code-variable jet printing, and gum coating; 2, release layer and information layer coating, mould pressing, vacuum aluminum plating, local aluminum washing, location two-dimension code-variable jet printing, and gum coating.

Description

technical field [0001] The invention relates to the fields of anti-counterfeiting marks and anti-counterfeiting labels, in particular to the combined application of OVD hot stamping foil and two-dimensional codes. Background technique [0002] The aluminized film washing process, also known as the aluminum removal process, is also called the partial hollowing out aluminum process. Widely used in product packaging. Generally speaking, the laser label is made of aluminized film material, and aluminum washing is to wash off a certain part of the aluminum film, so that the color and pattern of the bottom of the label can be revealed, which can achieve a certain anti-counterfeiting effect and is very beautiful. To improve the product grade, the anti-counterfeiting aluminum washing technology is laser aluminum washing technology, which uses a special process to hollow out the aluminum film, so that the surface of the laser anti-counterfeiting label presents the required transpare...

Problems solved by technology

[0005] In order to solve the shortcomings of anti-counterfeiting marks prepared by laser etching or aluminum washing process in the prior art, the anti-counterfeiting function is relatively simple, and the process equipment is relatively complicated, the production efficiency is low, and the equipment investment is large. Combined application of two-dimensional code and OVD positioning hot stamping foil, the production method of further processing the washed aluminum part on the OVD positioning hot stamping foil, enhancing its anti-counterfeiting mark with multiple anti-counterfeiting functions, and the production process of OVD positioning hot stamping foil , accurate aluminum washing technology and two-dimensional code variable code printing technology are organically combined to obtain a new type of two-dimensional code OVD positioning hot stamping foil with composite anti-counterfeiting function, which improves the efficiency of traditional laser etching production, and because this method is more expensive to equipment, The requirements for factory buildings and personnel configuration are simple, the investment is small, and the difficulty of expanding production scale is low, which is conducive to the promotion and improvement of anti-counterfeiting technology of commodities, and promotes the technological progress of the anti-counterfeiting printing industry
