Abstract

The invention discloses a laser die pressing method for loading digital anti-counterfeiting information. In the method, transfer paper made by performing die pressing on a coating, an aluminum layer, a laser layer and a release layer formed on base paper is used. The method is characterized in that a die pressing roller is provided with digital anti-counterfeiting information, and the digital anti-counterfeiting information is transferred onto the coating of laser transfer layer after the roller is heated to form a die pressing layer loaded with the digital anti-counterfeiting information; according to the digital anti-counterfeiting information, an explicit image is selected from a plurality of images, and the remaining images are digitally hidden into images which are only shown under a special optical lens by adopting net point operation. Compared with the prior art, the laser die pressing method has the advantages that various excellent performance of a general laser transfer product is achieved; moreover, an anti-counterfeiting die pressing layer which does not influence a subsequent printing process is formed, so that the application field of a laser product is expanded. The laser die pressing method is simple in process, is convenient to operate, and is low in production cost.

Description

A kind of laser molding method loading digital code anti-false information

Technical field

The present invention relates to laser molding technology, especially a kind of hidden image loads the laser molding method of digital code anti-false information.

Background technology

At present, the laser molding product that market is supplied generally all adopts seamless molded technique to make, and laser molding product has various physics and chemistry and the environmental-protecting performance of transfer product.Existing seamless molded technique needs could impress radium-shine product in the surperficial nickel coat version of roller, the loading of digital code anti-false information cannot be carried out, by being provided with the image concealing of anti-counterfeiting information on laser molding product, the application of laser molding product can not be greatly limit.

Summary of the invention

A kind of laser molding method loading digital code anti-false information provided for the deficiencies in the prior art is provided, microscopic carvings technique is adopted to be arranged in metal pattern roller by digital code anti-false information, radium-shine transfer product is made to load digital code anti-false information by mold pressing transfer printing, the anti-counterfeiting image hidden or word is made to be difficult to imitate, realizing metal pattern roller adopts seamless molded technology to carry out laser pattern and digital mold pressing making of hiding anti-counterfeiting information, product has well disguised and antifalsification, simple to operate, further reduction production cost, improve the economic benefit of enterprise.

The object of the present invention is achieved like this: a kind of laser molding method loading digital code anti-false information, comprise the laser transfer paper made through seamless laser mold pressing by the coating that base paper is arranged, aluminium lamination, radium-shine layer and release layer, be characterized in that the roller of described seamless laser mold pressing is provided with digital code anti-false information, the coating that digital code anti-false information to be transferred to laser transfer paper by roller after heating becomes the embossed plies loading digital code anti-false information; Described digital code anti-false information is formed by the fusion of multiple image encryptions; Described encryption is fused in multiple images selects one for dominant image, then adopts site computing, by the image that biometrics for remaining image hidden one-tenth only just can manifest under special optical eyeglass.

The heating-up temperature of described roller is 140 ~ 145 DEG C, and the pressure of transfer printing is 0.3 ~ 0.35mpa, and the speed of a motor vehicle is 35 ~ 40m/min.

Described number is hidden anti-counterfeiting information and is adopted microscopic carvings technique to be arranged on the metal matrix of roller.

The present invention compared with prior art not only has the various premium properties of usual radium-shine transfer product, but also have the false proof embossed plies not affecting rear road printing process concurrently, improve the anti-counterfeiting performance of product, expand the application of radium-shine product, technique is simple, easy to operate, reduce production cost further, greatly improve the economic benefit of enterprise.

Detailed description of the invention

The laser transfer paper that the present invention is made through seamless laser mold pressing by the coating that base paper is arranged, aluminium lamination, radium-shine layer and release layer; The roller of described seamless laser mold pressing is provided with digital code anti-false information, and the coating that digital code anti-false information to be transferred to laser transfer paper by roller after heating becomes the embossed plies loading digital code anti-false information; Described digital code anti-false information is formed by the fusion of multiple image encryptions; Described encryption is fused in multiple images selects one for dominant image, then adopts site computing, by the image that biometrics for remaining image hidden one-tenth only just can manifest under special optical eyeglass; Described number is hidden anti-counterfeiting information and is adopted microscopic carvings technique to be arranged on the metal matrix of roller.

The present invention in process of production by conduction oil by the roller heating temperatures of microscopic carvings to 140 ~ 145 DEG C, the roller temperature difference controls within 5 DEG C; Transfer pressure controls at 0.3 ~ 0.35mpa; The speed of a motor vehicle controls at 35 ~ 40m/min, the roller that microscopic carvings are good impresses on thermoplastic material, exactly the number on metal matrix being hidden anti-counterfeiting information is transferred in thermoplastic material coat side, sizing to be cooled be separated after, thermoplastic coating just defines the identical number with metal matrix and hides the embossed plies of anti-counterfeiting information.

The present invention not only achieves metal pattern roller and adopts seamless molded technology to carry out laser pattern and digital mold pressing making of hiding anti-counterfeiting information, and the technique restriction of the required nickel coat version in the surface changing laser molding roller, there is technique simple, easy to operate, the advantage that production cost is low.
