Problems solved by technology

[0004] Because the positioning holographic hot stamping process requires the cooperation of positioning holographic foil and special equipment, the positioning holographic foil and special equipment are extremely expensive and the cost of plate opening is high, so the cost of positioning holographic hot stamping process is generally high
[0005] Relatively speaking, the price of the copper plate hot stamping plate is relatively low, and the price of the equipment used for pressing the copper plate hot stamping plate is also relatively low, but the decorative effect and anti-counterfeiting effect of the copper plate hot stamping plate are obviously worse than that of the positioning holographic hot stamping foil

Abstract

The invention relates to the technical field of gold stamping processes, and particularly discloses a nanometer micro-carving anti-counterfeiting gold stamping process. The process comprises the following steps of step 1, designing a pattern according to a drawing, and carrying out pattern carving on a copper plate gold stamping plate by adopting a laser nanometer micro-carving machine; step 2, sequentially plating a zinc oxide layer, a titanium oxide layer and a protective layer on the surface of the copper plate gold stamping plate with a miniature carving pattern, step 3, flatly stamping the copper plate gold stamping step plate, and finally stamping the copper plate gold stamping plate. Through the process treatment, the reflected light color on the surface of the copper plate gold stamping plate presents corresponding specific colors at different incident angle changes to form a special colorful effect, the stereoscopic impression of a miniature carving pattern can be effectively improved, so that the anti-counterfeiting effect of the copper plate gold stamping plate after pressing and transfer printing is obviously improved, and the high-cost gold stamping process of a positioning holographic foil can be replaced, so that the gold stamping process has a better commercial prospect.

Description

technical field [0001] The invention relates to the technical field of bronzing technology, in particular to a nano micro-carving anti-counterfeiting bronzing technology. Background technique [0002] Hot stamping is also called anodized aluminum hot stamping. The hot stamping process uses the principle of heat transfer to transfer the aluminum layer in anodized aluminum to the surface of the substrate to form a special metal effect. Hot stamping is generally used on paper, plastic and cloth surfaces. [0003] Positioning holographic hot stamping is a special process application of holographic laser positioning anodized aluminum in the design. The pattern on the positioning holographic hot stamping foil has both decorative and anti-counterfeiting effects, which can greatly improve the grade of the product. [0004] Since the positioning holographic hot stamping process requires the cooperation of positioning holographic foil and special equipment, the positioning holographic...
