Packaging, printing, and production of new anti-counterfeiting technology - invisible barcode
Because counterfeit and shoddy goods have huge profit margins, inferior goods are flooded, and they cannot be eliminated endlessly, seriously damaging the interests of manufacturers and consumers. However, with the continuous development of anti-counterfeiting technology in packaging and printing, more and more anti-counterfeiting technologies have been discovered and applied to practice, and invisible barcodes are one of them. Today, we will talk about the invisible barcode anti-counterfeiting technology of packaging and printing. Invisible barcode can achieve neither destroy the overall effect of packaging and decoration, nor affect the purpose of barcode characteristics, the same invisible barcode after invisibility, the general counterfeiter is difficult to imitate, its anti-counterfeiting effect is very good, and there is no color problem when printing. There are several forms of invisible barcodes:
(1) Covered invisible barcode. The principle of this invisible barcode is that after the barcode is printed, it is covered with a specific film or coating, so that the barcode after processing is difficult for the human eye to read. The anti-counterfeiting effect of the covered invisible barcode is good, but its decoration effect is not ideal.
(2) Photochemically treated invisible barcodes. Use optical methods to process the ordinary visual barcode, so that it is difficult for people's eyes to find traces after processing, with ordinary wavelength light and non-specific light can not read it, this invisible barcode is completely invisible, the decoration effect is also very good, can also be designed into double anti-counterfeiting packaging.
(3) Paper invisible barcode. This invisible barcode invisible medium and paper through special photochemical treatment after integration, can not be peeled off, can only be used for one-time use, can not be identified by the human eye, can not be photographed with visible light, copy imitation, can only be used to emit a certain wavelength of the scanner to read the information in the barcode when discerning, while this scanner is also compatible with the general black and white barcode. Through the above introduction, do you have a comprehensive understanding of the invisible barcode packaging printing production anti-counterfeiting technology, for counterfeit and shoddy goods, we must strictly control the production of merchants, and improve the ability of consumers to identify real and fake goods.
