Problems solved by technology

[0002] Today, with the rapid development of two-dimensional codes, the characteristic that they are only composed of black and white code pictures has also been used to imitate two-dimensional codes by copying, taking pictures, photocopying, etc., which seriously hinders the harmony and stability of society and disrupts social order.
[0003] The Chinese patent No. ZL201120079652.0 discloses an anti-counterfeiting mark, but the two-dimensional code is invisible, and the two-dimensional code is completely hidden, so that people really can’t see the two-dimensional code and cannot imitate it. It can effectively fight against criminals, but for those who need to obtain information, they cannot read the QR code, thus losing the most basic function of the QR code

Embodiment 1

[0018] An anti-counterfeit two-dimensional code described in the embodiment of the present invention includes a visible two-dimensional code layer 2 visible to the naked eye; and an invisible pattern layer 1 invisible to the naked eye, and the invisible pattern layer 1 passes through an ultraviolet recognition device and an infrared recognition device It can be seen that the invisible pattern layer 1 is a special printing ink with a fineness of 10-20 μm, a fluidity of 25-38 mm, and a viscosity of 3-14.

[0019] Further, the composition of the special printing ink is calculated as follows by mass percentage:

[0020] 71-73% of special black ink with fineness ≤20μm;

[0021] 13-14% of red fluorescent powder with a particle size of 16-20 μm;

[0022] Blue phosphor with a particle size of 16-20 μm 13-14%;

[0023] Green fluorescent powder with a particle size of 16-20 μm 1-3%;

[0024] Preferably, the red fluorescent powder, blue fluorescent powder, green fluorescent powder, an...

Embodiment 2

[0035] An anti-counterfeiting two-dimensional code, including a visible two-dimensional code layer 2 visible to the naked eye; also includes an invisible pattern layer 1 invisible to the naked eye, and the invisible pattern layer 1 partially covers the visible two-dimensional code layer 2, as figure 1 As shown, the invisible pattern layer 1 is visible through the ultraviolet recognition instrument and the infrared recognition instrument. The invisible pattern layer 1 is a special printing ink with a fineness of 10 μm, a fluidity of 25 mm, and a viscosity of 3.

[0036] The preparation process of the special printing ink is as follows: in the special black ink with a mass percentage of 71% and a fineness of 20 μm, red fluorescent powder with a mass percentage of 13% and a particle size of 16 μm is respectively added, and the mass percentage is 13% of the blue fluorescent powder with a particle size of 16 μm and 3% by mass of the green fluorescent powder with a particle size of ...

Embodiment 3

[0042] An anti-counterfeiting two-dimensional code, including a visible two-dimensional code layer 2 visible to the naked eye; also includes an invisible pattern layer 1 invisible to the naked eye, and the visible two-dimensional code layer 2 partially covers the invisible pattern layer 1, such as figure 2 As shown, the invisible pattern layer 1 is visible through the ultraviolet recognition instrument and the infrared recognition instrument. The invisible pattern layer 1 is a special printing ink with a fineness of 20 μm, a fluidity of 38 mm, and a viscosity of 14.

[0043] The preparation process of the special printing ink is as follows: add red fluorescent powder with a mass percentage of 13% and a particle size of 20 μm to the special black ink with a mass percentage of 71% and a fineness of 14 μm. 13% blue fluorescent powder with a particle size of 20 μm, 1% by mass green fluorescent powder with a particle size of 20 μm, and 2% by mass calcium carbonate pigment, all mixe...

Abstract

The invention relates to an anti-fake two-dimensional code. The anti-fake two-dimensional code comprises a macroscopic visible two-dimensional code layer and further comprises a non-macroscopic invisible pattern layer. The invisible pattern layer can be seen through an ultraviolet identification instrument and an infrared identification instrument. Specially made printing ink is used for the invisible pattern layer, the fineness of the printing ink ranges from 10 microns to 20 microns, the fluidity of the printing ink ranges from 25 mm to 38 mm, and the viscosity of the printing ink ranges from 3 to 14. Through overlapped printing of the visible two-dimensional code layer and the invisible pattern layer, not only can the two-dimensional code be seen but also the two-dimensional code can be protected.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting, in particular to an anti-counterfeiting two-dimensional code. Background technique [0002] Today, with the rapid development of two-dimensional codes, the characteristic that they are only composed of black and white code pictures has also been used to imitate two-dimensional codes by copying, taking pictures, photocopying, etc., which seriously hinders the harmony and stability of society and disrupts social order. . [0003] The Chinese patent No. ZL201120079652.0 discloses an anti-counterfeit mark, but the two-dimensional code is invisible, and the two-dimensional code is completely hidden, so that people really can’t see the two-dimensional code and cannot imitate it. It can effectively fight against criminals, but it cannot read the QR code for those who need to obtain information, thus losing the most basic function of the QR code. How to obtain a method that can not only rea...
