Problems solved by technology

[0004] Two-dimensional codes provide a lot of convenience in information storage and identification in life. Although the anti-counterfeiting means of two-dimensional codes are gradually improved, various new technologies have been widely used in the field of two-dimensional code anti-counterfeiting. However, two-dimensional Codes are also imitated in large numbers, and the false information of some QR codes has brought great economic losses to consumers. Therefore, in the field of QR code anti-counterfeiting, more special methods should be adopted to achieve higher-end anti-counterfeiting
[0005] Based on the above existing technologies, it can be found that the existing improved technologies in the anti-counterfeiting field of two-dimensional codes are realized by means of information encryption, increase in the load information of two-dimensional codes, and invisible anti-counterfeiting of two-dimensional codes. These improved two-dimensional codes The code can only scan the code information in a bright environment, and cannot read the QR code information in a dark environment

Embodiment 1

[0043] The specific steps for the preparation of a luminous two-dimensional code that can be recognized in the dark are as follows:

[0044] (1) Use a computer two-dimensional code generator to generate the original two-dimensional code pattern containing anti-counterfeiting information, and then use photoshop software to change the original pattern part of the two-dimensional code original pattern generated by the generator into a blank, and replace the original pattern of the two-dimensional code The original blank part in is changed to a pattern, forming a reverse pattern;

[0045] (2) 0.2g of fluorescent quantum dot CdSe with a diameter of 10nm, 0.8g of higher alcohol fatty acid ester, 0.2g of emulsified silicone oil, 1g of acrylic resin, and 7.8g of varnish are fully stirred and mixed evenly, and left to stand for 1h to remove the foam. Obtain CdSe fluorescent ink, viscosity is 4800 centipoise;

Abstract

The invention discloses a light emitting two-dimensional code capable of being darkly and forwardly recognized and a preparation method thereof. The light emitting two-dimensional code capable of being darkly and forwardly recognized comprises a backing layer and a light emitting layer in sequence from bottom to top, wherein the light emitting layer is a two-dimensional code information layer andcomprises a two-dimensional code pattern part and a fluorescent light emitting part; the two-dimensional code pattern part is a blank part surrounded by the fluorescent light emitting part; the fluorescent light emitting part in the light emitting layer has a fluorescent light emitting characteristic in dark environment, so that the surrounded two-dimensional code pattern part is a backward two-dimensional code pattern and the backward two-dimensional code pattern can be forwardly recognized. According to the light emitting two-dimensional code, two-dimensional code patterns, comprising anti-fake information, generated by a computer two-dimensional code generator are processed as backward patterns, and the backward patterns are printed on backing layers by adoption of fluorescent link, sothat the effect of forwardly recognizing two-dimensional code information in dark environment is achieved; and the preparation method is simple to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of two-dimensional code display and preparation, in particular to a light-emitting two-dimensional code that can be recognized in the dark and forward and a preparation method thereof. Background technique [0002] For a long time, counterfeit and shoddy goods have endangered the vital interests of enterprises and consumers, and seriously affected the country's economic development. In order to protect the interests of enterprises and consumers and ensure the healthy development of the market economy, the country and enterprises spend a lot of manpower and financial resources on anti-counterfeiting and anti-counterfeiting every year. However, due to the lack of anti-counterfeiting technology and single anti-counterfeiting methods, ordinary consumers lack anti-counterfeiting tools and other factors, the anti-counterfeiting effect is not ideal. The appearance of the two-dimensional code just makes up for this...
