Novel alumite based on digital watermarking technology and production method thereof

Abstract

The invention provides novel alumite based on a digital watermarking technology. The novel alumite sequentially comprises a basic film layer, a separation layer, a coloring layer, a laser information layer, an aluminum-coated layer and a gluing layer from bottom to top, wherein a colorless transparent water base varnishing layer and a digital watermarking anti-fake information layer are arranged between the separation layer and the coloring layer; and the digital watermarking anti-fake information layer is formed by coating a printing plate for coating the digital watermarking anti-fake information layer onto the water base varnishing layer by adopting a conventional printing coating technology. The invention further provides a production method for the novel alumite based on the digital watermarking technology. According to the novel alumite based on the digital watermarking technology, the anti-fake reliability is further enhanced by using the digital watermarking technology, the anti-fake uniqueness and non-imitability are highlighted, and the characteristics of high confidentiality and randomness, no change of a visual image of the original printing product, no change of the mature printing process, no change of printing materials and equipment and no increment of the printing cost are achieved.

Description

technical field [0001] The invention relates to a novel electrochemical aluminum based on digital watermark technology and a preparation method thereof. Background technique [0002] Anti-counterfeiting occupies an extremely important position in the packaging and printing industry. With the development of social economy, the packaging of high-end products such as tobacco, alcohol, medicine, and cosmetics has higher and higher requirements for anti-counterfeiting, which is due to the fact that counterfeiting is becoming more and more serious in the market, and fake and inferior products are rampant in the market. Due to the high profit of cigarettes, a special commodity, the degree of counterfeiting is much higher than that of other commodities, so the application of anti-counterfeiting in cigarette packs is even more important. The application of anti-counterfeiting technology in cigarette pack printing enterprises is not simply to use a certain technology in printing, but...

Problems solved by technology

[0005] However, in the prior art, the anti-counterfeiting measures of anodized aluminum are single, the concealment is poor, the anti-counterfeiting pattern is easy to be obtained, and the imitation is not difficult; in addition, the existing anodized aluminum anti-counterfeiting technology has special requirements for printing equipment, and printing materials need to be changed. thus increasing the cost of printing
