Method for producing optical variable device (OVD) two-dimensional code hot stamping foil through aluminum washing process

Abstract

The invention provides an anti-fake mark production method which enables two-dimensional codes and optical variable device (OVD) positioning hot stamping foil to be combined to be applied, carries out further treatment on parts of the OVD positioning hot stamping foil undergoing aluminum washing and reinforces composite multiple anti-fake function of anti-fake marks. The production method aims at overcoming the shortcomings that in the prior art, anti-fake marks prepared through a laser etching or aluminum washing process are single in anti-fake function, process equipment is complex, production efficiency is low, and equipment investment is large, and the like. The production method improves efficiency on the basis of traditional laser etching production. Besides, due to the fact that the requirements of the method for equipment, plants and staff configuration are simple, the investment is small, the difficulty in expanding production scale is low, and the method is favorable for popularizing and improving an anti-fake technology of products and promotes technical progress of the anti-fake printing industry. The adopted technical scheme is that the method comprises coating of a release layer and an information layer, die pressing, printing of protecting gloss oil, positioning printing of aluminum washing ink in a code-varying code-spraying mode, vacuum aluminizing, partial aluminum washing, application of gum and striping.

Description

technical field [0001] The invention relates to the fields of anti-counterfeit marks and anti-counterfeit stamps, in particular to a method for preparing a hot stamping foil combined with an OVD positioning hot stamping foil and a two-dimensional code. Background technique [0002] For a long time, many commodities have been plagued by counterfeit goods, which have become a cancer that has been repeatedly banned and repeatedly beaten. In addition to the fact that counterfeiting is highly deceptive to consumers in terms of imitation, brand and price, there is another important reason. That is, the harmfulness of counterfeit goods has not been generally recognized by people, so that there is still a certain consumer market. The existence of a large number of counterfeit goods endangers people's health, causes a large loss of national tax revenue, and affects the effective and normal operation of the commodity market. The reason, in addition to the induction of high profits gen...

Problems solved by technology

[0009] In order to solve the problem that the aluminum washing method used in the prior art to prepare aluminum-plated hot stamping foil needs to use a corrosive aluminum washing agent, which is harmful to the operator and the environment and takes a long time, and to solve the problem of laser etching preparation The anti-counterfeiting function of the anti-counterfeiting mark is relatively simple, the process equipment is relatively complicated, the production efficiency is low, and the equipment investment is large. The field of one-to-one correspondence, that is, the anti-counterfeiting field of products combined with two-dimensional code information, through the corresponding printing treatment and aluminum washing treatment of OVD positioning hot stamping foil, the production process and precise aluminum washing of OVD positioning hot stamping foil 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 and its production method, which improves the efficiency of traditional laser etching production, and because the 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
