Novel alumite based on digital watermarking technology and production method thereof

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.
