At present, the market has more and more extensive anti-counterfeiting needs for various products, especially the anti-counterfeiting labels of cigarette pack products are more and more demanding. Anti-counterfeiting patterns mainly include dark lines, latent images, and unlocking and unlocking. Most of the existing technologies use gravure printing technology to make anti-counterfeiting patterns, but the problems of this gravure printing anti-counterfeiting technology are: (1) Due to the diffusion of printing ink, It has a great influence on the engraving accuracy. Such products cannot be very fine, and the most fine level that can be achieved in printed matter is generally 100 lines/cm; (2) The printing pattern is 2D plane, without 3D stereoscopic effect, making The latent image (that is, the 3D shape of the dots is reflected by different angles of light to hide the text or pattern in the shading, and the hidden pattern can only be seen through a certain angle), the anti-counterfeiting effect is poor; (3) Gravure printing production Unlocking and unlocking anti-counterfeiting patterns (that is, using dots or network lines as the basic unit to compose and express various printing patterns) cannot be better hidden, because the way of unlocking and unlocking is to slightly offset the position of the text or pattern that needs to be hidden, while printing. The difficulty lies in this offset amount. If the offset amount is made small, the ink will spread after printing, so that the hidden pattern cannot be seen with the unlocking sheet after printing the product, or the hidden pattern cannot be seen clearly, so it cannot play the role. Anti-counterfeiting effect; if the offset is larger, there is no need to use the unlocking piece, the hidden content can be seen with the naked eye, and the purpose of unlocking and anti-counterfeiting cannot be achieved.

The production method of an anti-counterfeiting mark that integrates a dark pattern, a latent image, and unlocking and unlocking of the present embodiment is as follows:

Step 1: Use image processing software to first create a uniformly arranged grid, and the shape of all the dots 1 in the grid is a three-dimensional hemisphere (as shown in FIG. 1 ).

Step 2: Offset the hemispherical dot 1 corresponding to the pattern to be hidden in the grid by a certain distance, and the offset is 0.02-0.04mm (the shifted dot 1 is shown in Figure 2). After the offset is good, the laser direct engraving machine is used to engrave on the copper roller, so as to obtain the hidden pattern 3 displayed after matching with the unlocking diaphragm 2 (as shown in Figure 3);

Step 3: Using image processing software, select some of the hemispherical dots 1 in the grid and design the angles to be cut, and then cut the surface of the hemispherical dots 1 from different cutting angles, so that the light passes through the cut dots 4 Then different latent image patterns 40 (as shown in Figure 4) are presented through different reflection angles, and then a laser direct engraving machine is used to engrave on the copper roller;

Step 4, utilize image processing software, select part of hemispherical dots 1 in the grid and reduce its entire outline to form hemispherical reduced dots 5, and these hemispherical reduced dots 5 form dark pattern 50 (recognizable to the naked eye) As shown in Figure 5), and then use a laser direct engraving machine to engrave on the copper roller;

Step 5. Electrolytic polishing is performed on the engraved pattern residue on the copper roller, so that the surfaces of all the dots 1 are smooth and free of burrs;

Step 6, chrome plating is performed on the electropolished copper roller to increase the hardness and corrosion resistance;

Step 7: Assemble the processed copper roller on the embossing machine, and emboss the substrate, that is, to obtain an anti-counterfeiting layer integrating dark pattern, latent image and unlocking; , the transfer rate is as high as 95% or more, and the engraved pattern can be well transferred to the required substrate.
