Problems solved by technology

[0002] At present, the use of two-dimensional codes is becoming more and more widespread. The traditional black and white two-dimensional codes are easy to be imitated and cannot achieve anti-counterfeiting effects well, which may become a hidden danger to personal information and property security

Embodiment 1

[0028] Embodiment 1: When the entirety of the two-dimensional code is printed with optically variable ink, the two-dimensional code displays one color when viewed directly, and another color when viewed obliquely.

[0029] Such as figure 1 As shown, the QR code is printed with green-to-blue light-changing ink as a whole. When you look directly at it, you can see the green QR code in the picture, and when you look sideways, you can see the blue QR code in the picture. The optically variable two-dimensional code presents a color-changing visual effect when directly viewed and displayed, and can enhance the viewing and attractiveness of an effective two-dimensional code.

[0030] Wherein, the background color of the printed matter is consistent with or different from the color displayed when the two-dimensional code is viewed directly, or the background color of the printed matter is consistent with or different from the color displayed when the two-dimensional code is viewed obl...

Embodiment 2

[0034] Embodiment 2: When at least a part of the area in the two-dimensional code is printed with one or more optically variable inks, the rest of the area is printed with ordinary ink, and the area of ​​the optically variable ink displays a color when viewed directly , to display another color when squinting, so that the color displayed in some areas printed with optically variable ink is the same or different from the color displayed in the rest of the area printed with ordinary ink in the two-dimensional code, or using optically variable ink The color displayed when the part of the printed area is squinted is the same as or different from the color displayed by the rest of the area printed with ordinary ink, or the color displayed when the part area printed with optical variable ink is viewed directly or squinted is the same as the color displayed by the two-dimensional code. The rest of the QR code printed with ordinary ink displays different colors.

[0035] In this embod...

Embodiment 3

[0037] Embodiment 3: Part of the color block area of ​​the two-dimensional code is printed with optical variable ink, and the optical variable ink area forms a specific graphic, and the remaining two-dimensional code area is printed with ordinary ink, and some areas printed with optical variable ink are directly printed. The color displayed when viewed is different from the color displayed in the remaining area of ​​the QR code printed with ordinary ink, and the color displayed when squinted is consistent with the color displayed in the remaining area of ​​the QR code printed with ordinary ink. The two-dimensional code can realize the visual effect of displaying and hiding graphics and texts when switching between frontal view and squint view.

[0038] Such as Figure 5 As shown, the flying bird pattern is printed with green-to-blue light-changing ink, and the rest of the QR code area is printed with ordinary blue ink. The green bird can appear when looking directly at it; the...

Abstract

The invention discloses an anti-counterfeit two-dimension code. The two-dimension code printed by adopting optically variable ink is arranged on at least one of the front and the back sides of a printed object, and the two-dimension code is printed by wholly or partially adopting optically variable ink. Color block areas printed by adopting the optically variable ink can form the specific numbers, characters, patterns and the like and can present different colors when observed straightly or slantwise, so that the ornamental value and attraction of the two-dimension code are effectively promoted. Meanwhile, through the reasonable mixing of the optically variable ink and common ink, the optically variable ink area and the surrounding color block areas printed by adopting the common ink display the same color or different colors when the two-dimension code is observed straightly or slantwise, and thus the two-dimension code presents the dynamic vision effect with the specific patterns during switching of straight observation and slantwise observation. In addition, the information including the number, distribution and color of the color blocks on the front and back of the two-dimension code is acquired through an encryption algorithm, and for a person not mastering the encryption algorithm, the two-dimension code with a series of regular change can not be formed.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code design, in particular to an anti-counterfeiting two-dimensional code with high anti-counterfeiting ability. Background technique [0002] At present, the use of two-dimensional codes is becoming more and more widespread. The traditional black-and-white two-dimensional codes are easy to be imitated, cannot achieve anti-counterfeiting effects well, and may become a hidden danger to personal information and property security. The optical variable process and counter-printing process are unique anti-counterfeiting technologies for securities printing. It is difficult to imitate ordinary water offset printing equipment in the society, and it is easy to distinguish the authenticity with the naked eye, which can significantly improve the viewing and anti-counterfeiting performance of the two-dimensional code. Effectively protect the security of information and property of users who scan QR...
