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.

Embodiment 1

[0032] The intaglio electromechanical engraving method with anti-counterfeiting effect of this embodiment comprises the following steps:

[0033] (1) Determine the size of the diamond-shaped cells according to the black graphic to be printed, and determine the cell arrangement angle θ of the entire gravure, θ=∠KRS, such as Figure 5 shown;

[0034] (2), in all graphic areas of the entire intaglio, Figure 5 The area enclosed by the middle parallelogram KGPS is located in the middle segment of one of the straight line segments (in Figure 5 Among them, the parallelogram KGPS itself is an integral part of the graphics and text, representing a straight line segment, there are graphics and texts above the KG, and graphics and texts below the PS, Figure 5 The parts above the KG and below the PS are omitted). Select one of the local straight line segments (the area surrounded by the parallelogram KGHW) as the anti-counterfeiting label position, and the selected straight line seg...

Embodiment 2

[0038] The main difference between the second embodiment and the first embodiment is that in the second embodiment, two straight line segments of the same color are selected as the anti-counterfeiting marking parts, and the extension angles of the straight line segments of the two straight line segments differ by 12°, that is, the first straight line segment The angle difference between the extension angle α of the segment and the cell arrangement angle θ of the entire gravure plate is 15°, and the angle difference between the extension angle α of the second straight line segment and the cell arrangement angle θ of the entire gravure plate is 27°. In this way, it is more conducive to identification, and it is more difficult to counterfeit. This is because: since the cell arrangement angle of the color of the counterfeiter has only one value, no matter whether the value of the cell arrangement angle of the entire plate roll of the counterfeiter imitates the original The value o...

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-...
