Problems solved by technology

[0004] However, the above anti-counterfeiting imprints and seals, regardless of the ink or the seal itself, are easy to forge, so the anti-counterfeiting effect is not good

Embodiment 1

[0022] A perspective information anti-counterfeit imprint 1 of the present invention, as shown in Figure 1, a plurality of visible dots 12 in the imprint 1 are arranged in an orthogonal matrix, and from a microscopic point of view, some mobile dots 12a in the dots 12 move horizontally to the same side at the same time Offset by a certain distance L, at this time, a vacancy 13 will be left on the original position of the removed mobile network point 12a. The combination of mobile network dots 12a can form different hidden patterns. Since the size of network dots 12 is small, the spacing is also small, and the moving distance is also small, so the pattern cannot be seen macroscopically, and it can only be seen through certain patterns. The verification method can be displayed.

[0023] The verification method for verifying the authenticity of the anti-counterfeiting imprint 1 is realized by a transparent verification film 2 as a base material, as shown in Figure 2, the verificat...

Embodiment 2

[0032] Other conditions are the same as those in Embodiment 1, except that the mobile dots 12a are vertically offset by a certain distance L to the same side at the same time.

[0033] At this time, as long as the dark stripes 21 of the verification film 2 are placed parallel to the horizontal dot row on the blot 1, and the verification film 2 is slightly moved vertically, the same see-through pattern effect as in the first embodiment can be produced.

Embodiment 3

[0035] Other conditions are identical with embodiment 1 or embodiment 2, just:

[0036] The distance L that the mobile network point 12a is offset to the same side at the same time is not equal to the width w2 of the network point 12. If L

[0037] When the dark stripes 21 coincide with each row of network dots 12, all the network dots 12 and vacancies 13 are blocked, and only the parts of the mobile network dots 12a between the network dots 12 are exposed. Therefore, it is also possible to show the male mold of the...

Abstract

The invention discloses anti-fake trace with visible information, it includes multiple rowed visible net dot, part of mobile net dot moves to the same side, forms connotative pattern. It also discloses a testing tool and method for mentioned perspective information anti-fake prints, the base material is transparent testing glue which is used as testing tool to test the anti-fake print, the testing glue is arranged with several lighttight dark stripes, the dark stripes can cover on each row of net dot or among the dots, thus exposes the pattern formed by the movement of mobile net dots; the invention also discloses a anti-fake stamp for printing the mentioned perspective information. It is not easy to be forged, and the method and tool are simple, and convenient.

Description

technical field [0001] The present invention relates to an anti-counterfeiting imprint, in particular to a perspective information anti-counterfeiting imprint, a verification tool and a verification method for verifying the authenticity of the imprint, and a seal for printing the imprint. Background technique [0002] After the common seal is imprinted, to verify the authenticity of the imprint, it can only be checked by overlapping another imprint for the record, so that the imprint and seal are easy to forge, and the security is very poor. [0003] Some anti-counterfeiting imprints are changed by changing the properties of the ink, such as after the ink dries, it changes color or fluoresces when exposed to ultraviolet rays. [0004] But above anti-counterfeiting blot and seal, no matter ink or seal itself all are easy to forge, so anti-counterfeiting effect is bad. Contents of the invention [0005] The present invention overcomes the shortcomings of the prior art, prov...
