[0037] Example

[0038] like figure 1 As shown, the label with the light-column color-changing effect includes a light-column color changing effect layer 1, a printing layer 2, an upper paper layer 3 and a lower paper layer 4, and an upper paper layer 3 and a lower paper layer 4, which are arranged in sequence from top to bottom. A fluorescent fiber 5 and a microscopic two-dimensional code information security thread 6 are arranged between, wherein the light column color changing effect layer 1 is printed with magnetic ink, and the light column effect is formed by fixed magnetism.

[0039] The information security line 6 of the micro-two-dimensional code is distributed between the upper paper layer 3 and the lower paper layer 4 .

[0040] The fluorescent fiber 5 and the micro-QR code information security thread 6 play the roles of anti-counterfeiting identification and enterprises' anti-counterfeiting inquiry.

[0041] The miniature two-dimensional code is a DM code, and the...

Abstract

The invention relates to an anti-counterfeit label, concretely relating to a label with light pillar color-changing effect and a preparation method thereof. The label with light pillar color-changingeffect comprises a light pillar color-changing effect layer, a printing layer, a paper feeding layer and a paper discharge layer, all of which are orderly arranged from the top to the bottom. A fluorescence fiber and miniature two-dimensional code information safety line is arranged between the paper feeding layer and the paper discharge layer. Magnetic printing by ink is adopted by the light pillar color-changing effect. Additionally, the light pillar effect is formed by fixed magnetization. The invention provides the label with light pillar color-changing effect. The label is difficult to copy. When a customer identifies, the light changing effect is obtained. The printing ink has a dynamic changing effect and is highly anti-counterfeiting. Because of the fluorescence fiber and miniaturetwo-dimensional code information safety line, multiple anti-counterfeiting is achieved. The identifying operation is simple. The label is not easy to copy and has great anti-counterfeiting effect. The preparation method is scientific, reasonable, simple and easily implemented.

Description

technical field [0001] The invention relates to an anti-counterfeit label, in particular to a label with a light column discoloration effect and a preparation method thereof. Background technique [0002] Optically variable inks are also called optically variable inks or chameleons, and the printed color blocks present a pair of colors, such as: red-green, green-blue, gold-silver, etc. Looking straight or sideways under white light, with the change of the human eye’s angle of view, it presents two different colors, with strong light-changing characteristics, large color difference changes, and obvious features, which can be recognized without any equipment, and its color angle effect cannot Use any high-definition scanners, color copiers and other equipment to reproduce, and the printing features cannot be imitated by any other ink and printing methods. The anti-counterfeiting reliability is extremely strong, so it is designated by many countries in the world as the most dem...
