Problems solved by technology
[0002] In order to prevent counterfeit products, the existing methods are to add laser holographic images on the product packaging, or to add anti-counterfeiting marks on the packaging by image dot interference method. Due to the limitation of printing technology, these two methods can only be used alone. Using one, the former laser holographic image can make it easier for consumers to identify anti-counterfeiting marks, but the anti-counterfeiting effect is not good, and because the surface tension on the laser holographic image film is low, it brings a lot of trouble to printing, such as: laser The surface tension of the holographic image film is usually only 33-34 dynes / CM. For solvent-based inks that are gravure printed into flexographic plates, they can be printed only after corona treatment, but for offset printing (lithographic printing) Paper packaging, non-solvent offset printing ink can not make the ink adhere to the surface of the laser holographic image film only through the method of corona treatment and cannot be printed
Although the latter method has better anti-counterfeiting effects, image dot interference must be identified with special tools, which is inconvenient for consumers.
The purpose of the present invention is to solve the problems of the prior art, apply two different anti-counterfeiting technologies to the same product, enhance the anti-counterfeiting function, and solve the problem that offset printing (flat printing) cannot be carried out on the surface of the laser holographic image film

Embodiment
[0014] Further illustrate the embodiment of the present invention below in conjunction with accompanying drawing: on the laser holographic image film 1 that makes according to common laser holographic image technology, pre-coat one deck can improve its surface tension coating, this coating formula is: vinyl chloride resin: 18 -30%, solvent: 67-79%, other additives: 3-7%, the solvent in the formula is an ether or ketone solvent, and other additives are mainly defoamers, wear-resistant agents and adhesives; The ester or ketone is diluted to a viscosity of 18-23 mPa·s, coated with a gravure plate, and then heated and dried at a temperature of 50-70 degrees Celsius for 2-4 seconds. The precoated and dried laser holographic image film is compounded with cardboard 5 on an ordinary laminating machine to make a product to be printed.

An antiforge package with halftone dot interference and holographic laser image is prepared through applying a paint layer on holographic laser image film, drying combining it with paperboard, preparing halftone dot interference image by computer, combining it with needed words and pattern, making print plate, offset printing, and generating a surface tension increasing layer.
Description
Technical field: [0001] The invention relates to an anti-counterfeiting printing technology, in particular to a production method for combining dot interference and laser holographic images on the same anti-counterfeiting package. Background technique: [0002] In order to prevent counterfeit products, the existing methods are to add laser holographic images on the product packaging, or to add anti-counterfeiting marks on the packaging by image dot interference method. Due to the limitation of printing technology, these two methods can only be used alone.
