Gravure electronic mechanical carving method with anti-fake function

Abstract

The invention discloses a gravure electronic mechanical carving method with an anti-fake effect. The gravure electronic mechanical carving method comprises the following steps of (1) determining the size of a rhombus ink cell according to the required printed image, and determining an ink cell arrangement angle theta of the whole gravure; (2) selecting at least one straight line section as an anti-fake identification part, wherein the selected straight line section can meet the following conditions that the angular difference between an extending angle alpha of the straight line section and the ink cell arrangement angle theta of the whole gravure is 10 degrees-30 degrees; (3) revising the design value of the partial ink cell arrangement angle of the straight line section of the anti-fake identification part again, enabling the partial ink cell arrangement angle of the straight line section to be just be equal to the extending angle alpha of the straight line section, and recording the position of the straight line section; and (4) according to the design result, carrying out ink cell carving by adopting an electronic machine carving method to obtain a gravure with an anti-fake effect. The gravure electronic machine carving method provided by the invention has the advantages that the image printed by the carving gravure has the anti-fake effect, the identification is easy, the copy is hard, and the fabricating cost is also not increased.

Description

[0001] technical field [0002] The invention belongs to an intaglio engraving process, and in particular relates to an intaglio electromechanical engraving method with anti-counterfeiting function. Background technique [0003] With the proliferation of counterfeit products, people have been pursuing the anti-counterfeiting function of the packaging graphics of products. The users of the anti-counterfeiting function may be ordinary end consumers, or they may be special groups of people who need certain tools, such as product business units or market supervision units. For the business unit of the product, once a fake product appears, it will not only impact the market, but also in the case of quality problems of the counterfeit product, it is often unjustly returned, unjustly assumed responsibility for product quality, and unjustly punished. Therefore, product business units or market supervision units also need to pursue anti-counterfeiting effects, even though such anti-...

AI Technical Summary

Problems solved by technology

[0011] As mentioned above, the gravure meshes produced by the existing electromechanical method have a large area. Usually, there may be dozens of mesh lines within 1 cm (each mesh line is composed of multiple mesh holes arranged in a line), Appears rough, low precision, easy to imitate, difficult to form anti-counterfeiting effect

Therefore, when genuine manufacturers encounter counterfeit returns or quality problems, they often lack convincing evidence to prove that the product is counterfeited by others.
