Embodiment 1

[0027] The anti-counterfeiting paper with intelligent miniature two-dimensional codes, from bottom to top, is the lower paper layer 4, the substrate layer 3, the intelligent miniature two-dimensional code layer 2, and the upper paper layer 1. The two-dimensional code is a square with a side length of 4mm.

[0028] The preparation method of the anti-counterfeiting paper with intelligent miniature two-dimensional code is prepared according to the following steps:

[0029] (1) Microprinting: Print a miniature two-dimensional code on the substrate, the two-dimensional code is square, and the side length is 4mm;

[0030] The color of the miniature two-dimensional code is colorful or monochrome, and the two-dimensional code can be printed in one color, for example: red, blue, green, black and other colors. QR codes can also be colorful.

[0031] (2) Die-cutting: Use a die-cutting machine to scan, enter information, punch and die-cut the printed QR code substrate, and die-cut into ...

Embodiment 2

[0040]The side length of the two-dimensional code is 2 mm, and there are 8 die-cut miniature two-dimensional codes per 50 square centimeters during papermaking, and the rest are as in Example 1.

Embodiment 3

[0042] The side length of the two-dimensional code is 3 mm, and there are 6 die-cut miniature two-dimensional codes per 40 square centimeters during papermaking, and the rest are as in Example 1.

Abstract

The invention belongs to the technical field of anti-counterfeiting of materials, in particular relates to anti-counterfeiting paper with intelligent micro two-dimensional codes. The anti-counterfeiting paper with the intelligent micro two-dimensional codes is formed by a lower paper layer, a base material layer, an intelligent micro two-dimensional code layer and an upper paper layer sequentially from bottom to top, wherein the two-dimensional codes are square, and the edge length of each two-dimensional code is 1mm to 6mm. The invention also relates to a preparation method of the anti-counterfeiting paper with the intelligent micro two-dimensional codes. The preparation method comprises the following steps of microprinting, die cutting and papermaking, wherein at least one die-cut micro two-dimensional code is arranged on the area of every 10 to 50 square centimeters. The prepared intelligent anti-counterfeiting paper has the characteristic that the edge length of each two-dimensional code is only 1mm to 6mm, the occupation area is small, and the storage amount of other information is not influenced. The intelligent micro two-dimensional codes cannot be read by virtue of the normal photographing of a mobile phone, the information inside the intelligent micro two-dimensional codes only can be inquired by virtue of the photographing of a more-than-50-time magnifying lens, and thus the counterfeiting difficulty is increased. When the information in the micro two-dimensional codes is inquired by a customer, the hidden two-dimensional codes need to be taken out to be read in a magnifying and scanning manner, the anti-counterfeiting paper is damaged, and thus the reutilization of the anti-counterfeiting paper is prevented.

Description

technical field [0001] The invention belongs to the technical field of material anti-counterfeiting, and in particular relates to an anti-counterfeiting paper with an intelligent miniature two-dimensional code, a preparation method and an application thereof. Background technique [0002] At present, in the field of anti-counterfeiting technology, anti-counterfeiting base materials occupy an important position, such as various anti-counterfeiting papers. Antifalsification paper is a general term for special papers with marks or hidden marks (patterns, patterns, watermarks, numbers, etc.) on the surface, which are not easy to imitate, fake or change. [0003] Commonly used are security thread paper, fiber paper, anti-counterfeiting holographic paper, watermark paper and so on. Security thread paper, fiber paper, anti-counterfeiting holographic paper, watermark paper, etc. are now widely used. These anti-counterfeiting papers are a major advance in the anti-counterfeiting of ...
