Description
Technical field
The present invention relates to accurate coated product field, relate in particular to a kind of antiforge function film and manufacture method.
?
Background technology
At present, fake and inferior commodities have become international one large public hazards to the impact in market, and according to statistics, the turnover of fake and inferior commodities accounts for the 5%-6% of quantum of world trade, reach every year hundred million dollars of 1500-1800, this harm causes the attention of countries in the world already.China is worldwide manufacturing works, and it is complete that product is contained class, and output is large, and the harm of counterfeit and shoddy goods is more obvious.Therefore, antifalse technology is huge in Chinese market, and according to authoritative sources, Chinese false proof market capacity reaches 8,000 hundred million yuan.
Current domestic main flow is false proof is mainly watermark and radium-shine, and these two kinds of main ways have not had innovation for more than ten years, and what master a skill is common numerous, does not meet the false proof demand that requires information blockage/singularity/exclusiveness, easily by counterfeit.3D dynamic anti-fake label is developed and is formed with great concentration for Sweden scientist finds the ，You Sweden CRANE CURRENCY company time for many years of going through the earliest, has technique, on some main flow high-end products, uses this technology.The technique using on currency is called as " MOTION safety line ", be commonly called as " dynamic safety line ", " dynamic security line " or " movable image safety line ", study carefully its essence, being a kind of material based on micro-optic having on banknote, can there is smooth slip and displacement according to the variation of people's observation visual angle in its image.The dynamic image of this continuous variation can be according to inclination mode all around of the outward appearance of image and hand-held bill and is recognized at an easy rate, and therefore, this significant effect has caused people's notice and curiosity very soon.But this " dynamic safety line " can only be seen clearly in one side, only have one side can play false proof effect, another side does not have false proof effect; In addition, the manufacture method of this " dynamic safety line " is complicated, and production efficiency is low, and its production cost is also high, can not meet the growing demand in market.
Summary of the invention
The technical problem to be solved in the present invention is, for " dynamic safety line " in prior art, only have one side can play anti-fake effect, its manufacture method is complicated, production efficiency is low and production cost is high above-mentioned defect, a kind of antiforge function film and manufacture method are provided, described antiforge function membrane structure is simple, its upper and lower surface all can have antiforge function, dynamically display effect is good, and the manufacturing process of described antiforge function film is simple, production efficiency is high, and its production cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of antiforge function film, comprises interconnective first information layer and the second Information Level; On first information layer and the second Information Level, be respectively equipped with by identical rule and distribute and corresponding first module structure and second unit structure, and first module structure and second unit structure are letter or image.
