Problems solved by technology

[0003] However, at present, optically variable inks are directly printed by screen printing equipment, and the existing defects are: the label only has optically variable effects, and there is no dynamic light column or aperture change effect. With the advancement of technology, some unscrupulous merchants have been able to print this packaging counterfeiting

Embodiment

[0038] Such as figure 1 As shown, the label with the photocolumn discoloration effect includes the photocolumn discoloration effect layer 1, the printing layer 2, the upper paper layer 3 and the lower paper layer 4, the upper paper layer 3 and the lower paper layer 4 arranged in sequence from top to bottom A fluorescent fiber 5 and a miniature two-dimensional code information security thread 6 are arranged between them, wherein the photocolumn discoloration effect layer 1 is printed with magnetic ink, and the photocolumn effect is formed through fixed magnetism.

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

[0040] The fluorescent fiber 5 and the miniature two-dimensional code information security thread 6 play the role of anti-counterfeiting identification and enterprise anti-counterfeiting inquiry.

[0041] The miniature two-dimensional code is a DM code with a height o...

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...
