Problems solved by technology

[0003] Existing laser anti-counterfeiting marks have some shortcomings in practice: conventional laser holographic images are formed by embossing a holographic nickel plate on a polyester film. The layout or pattern of the laser image of the laser anti-counterfeiting mark produced by this method is very limited, and can only be used for repeated printing of the same finalized pattern
However, in this technology, the random number itself does not have any anti-counterfeiting technology, so it is generally necessary to cover the random number in the form of coverage
This technology is not only complicated in process, but also has almost no anti-counterfeiting ability in the form of coverage. The main anti-counterfeiting ability lies in the telephone anti-counterfeiting system, but the technical content of today's telephone anti-counterfeiting system is not high, and counterfeiters are fully capable of copying or imitating

Embodiment approach 1

[0029] Such as figure 1 As shown, the anti-counterfeiting method in this embodiment specifically includes the following steps:

[0030] Step 1, making a carrier with a laser holographic effect on one side, the carrier at least includes a base layer, a metal layer and a transparent photosensitive material layer from bottom to top, and the side where the transparent photosensitive material layer is bonded to the metal layer is a laser pressing surface;

[0031] In step 2, digital printing or digital printing is used to print transparent ink or colored ink on the same surface of the transparent photosensitive material layer, and the printed or printed graphic units are different. If linear printing or graphic unit printing is adopted in step 2, then after step 5, the packaging pull line of linearly arranged graphic unit will be obtained; if block printing or graphic unit printing is adopted in step 2, then step 5 Before, it was necessary to coat the adhesive layer on the other s...

Abstract

The invention relates to a laser anti-counterfeiting technology, in particular to a variable graphic anti-counterfeiting method with laser holographic effect. The method specifically comprises the following steps: step 1) making a carrier, wherein one side of the carrier has the laser holographic effect; step 2) adopting the digital printing way for printing transparent ink or color ink on the same side of a transparent photosensitive material layer, wherein the printed graphic units are different; step 3) carrying out high-intensity ultraviolet exposure on the printed surface; step 4) adopting alkaline solution for washing away the transparent photosensitive material layer which is not covered by the transparent ink and a metal layer below the transparent photosensitive material layer; step 5) cutting the carrier by taking each graphic unit as a unit and step 6) applying an anti-counterfeiting unit in an anti-counterfeiting package. The method can realize the anti-counterfeiting property by forming the different hollow graphic units with the laser holographic effect on the carrier, that is, the method realizes the laser variable data anti-counterfeiting property.

Description

technical field [0001] The invention relates to a laser anti-counterfeiting technology, in particular to a variable image-text anti-counterfeiting method with a laser holographic effect. Background technique [0002] Laser holographic technology is a widely used anti-counterfeiting technology, which achieves the purpose of anti-counterfeiting by making a laser holographic image on the label, hard box or film packaging, or the pull line of film packaging. Carriers such as labels, packaging, or packaging pull wires with laser holographic images on them can be collectively referred to as laser anti-counterfeiting marks. [0003] There are some deficiencies in the existing laser anti-counterfeiting marks in practice: the conventional laser holographic image is formed by embossing the holographic nickel plate on the polyester film, and the layout or pattern of the laser image of the laser anti-counterfeiting mark produced in this way is Very limited and can only be used for repe...
