Problems solved by technology

However, although this method improves the concealment, it uses two kinds of magnetic materials for overprinting, and the production difficulty and production cost are relatively high
[0005] In addition, at present, the security thread that combines the first-line and second-line anti-counterfeiting features is mainly a combination of magnetic coding and non-magnetic graphics. The combination of magnetic codin

Embodiment Construction

[0029] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. Moreover, those skilled in the art should understand that the gray levels and size ratios in all the drawings are only schematic and do not represent actual colors and size ratios.

[0030] figure 1 (a)-1(c) show a schematic structural view of the anti-counterfeiting element in an embodiment, a top view and a signal waveform obtained by detecting the anti-counterfeiting element through a magnetic sensor. Such as figure 1 As shown in (a), the embodiment of the present invention provides a kind of anti-counterfeit element, and this anti-counterfeit element can comprise: substrate 10 and the magnetic region that is arranged on this substrate 10 and is made of a kin...

Abstract

The invention relates to the false proof field, and discloses a false proof element and a false proof product; the false proof element comprises a substrate, and continuous magnetic zones made of the same material and arranged on the substrate, wherein the magnetic zones comprise a plurality of first and second zones arranged at intervals, and the remanent magnetism of the first zone is bigger than that of the second zone. The false proof element can well hide magnetic coding zones, and is simple in making technology and low in cost.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting, in particular to an anti-counterfeiting element and an anti-counterfeiting product. Background technique [0002] At present, magnetic materials are widely used in the field of anti-counterfeiting. The early magnetic security thread adopts a full-page coating method, such as patent: GB1127043, which is to evenly coat a layer of magnetic material on the entire security thread. Use the magnetic sensor to detect the magnetic material on the security line. If the magnetic signal can be detected, it is true, otherwise it is false. However, on the security thread formed by this coating method, the magnetic sensor can only detect the presence or absence of magnetism, and cannot generate a magnetic coding sequence, and this coating method is easy to be counterfeited. [0003] In order to enhance the anti-counterfeiting performance of the security thread, the patent EP0310707A2 applied by Mantegazza Co...
