Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.
A holographic anti-counterfeiting printing paperboard comprises a printing stock, a holographic anti-counterfeiting layer and a common printing layer;
the holographic anti-counterfeiting layer is formed by coating a water-based transparent coating mixed with laser holographic film fragments on the surface of a printing stock, a plurality of holographic anti-counterfeiting marks are printed on the laser holographic film, each holographic anti-counterfeiting mark is composed of an anti-counterfeiting pattern and an anti-counterfeiting serial number, the anti-counterfeiting pattern size information in the holographic anti-counterfeiting marks is different from each other, the anti-counterfeiting serial numbers are encrypted by adopting a molar interference encryption technology, and the anti-counterfeiting serial numbers correspond to the anti-counterfeiting marks one to one.
The double-layer anti-counterfeiting mark is adopted, when anti-counterfeiting identification is carried out, firstly, the anti-counterfeiting serial number part is decrypted by using the secret key to obtain the serial number recorded in the anti-counterfeiting serial number part, then, anti-counterfeiting pattern identification is carried out according to the corresponding relation between the serial number and the anti-counterfeiting pattern size information in the holographic anti-counterfeiting mark, so that the anti-counterfeiting identification is completed.
Based on the holographic anti-counterfeiting printing paperboard, the printing process is provided, and comprises the following steps:
making a holographic graph-text plate: firstly, engraving a pre-designed anti-counterfeiting pattern and a Moire with label information on a photoresist plate by using a photoetching machine; then, silver plating is carried out on the photoresist plate with the anti-counterfeiting pattern and the Moire with the label information; then, electroforming the photoresist plate to obtain a single nickel plate forming a single holographic anti-counterfeiting mark; finally, splicing a plurality of single nickel plates into a large holographic image-text plate by using a plate splicing machine, and plating the large holographic image-text plate after silver plating to form the large holographic image-text plate;
manufacturing a laser holographic film: firstly, transferring the pattern of the holographic image-text plate to an aluminized layer of a PET film with an aluminized surface by utilizing an embossing thermal transfer technology to form an information layer; then, coating the scratch thermoprinting layer on the information layer at the temperature of 100-140 ℃ to form a scratch thermoprinting layer; finally, coating the hot stamping glue layer on the scraping hot stamping layer at the temperature of 120-130 ℃ to form a hot stamping layer, and manufacturing a laser holographic film;

and (3) ordinary printing: and printing common pictures and texts on coated paper, white cardboard, gold and silver cardboard or a laser card.
Because the double-layer encryption technology is adopted in the anti-counterfeiting printing paperboard, each holographic anti-counterfeiting mark comprises anti-counterfeiting patterns and anti-counterfeiting numbers with different sizes, under the condition of no secret key, the anti-counterfeiting numbers cannot be accurately identified, so that a counterfeiter cannot accurately obtain the corresponding relation between the anti-counterfeiting numbers and the anti-counterfeiting patterns when performing imitation, the counterfeiter cannot obtain complete plate-making information, the imitation cost and the imitation difficulty are greatly improved, the corresponding relation between the anti-counterfeiting numbers and the anti-counterfeiting patterns can be regularly replaced according to actual conditions, and absolute anti-counterfeiting is realized.
In summary, the invention has the advantages that: the holographic anti-counterfeiting printing paperboard adopts double-layer anti-counterfeiting marks, greatly increases the imitation difficulty, effectively improves the anti-counterfeiting effect and has great market benefit.
