Background technology
Laser holography is a kind of use anti-counterfeiting technology widely, and this technology reaches false proof purpose by make the image with laser hologram in the backguy of label, hard box or blister-pack or blister-pack.This carriers such as label, packing or packing backguy that have laser hologram image on it can be referred to as laser anti-fake figure mark.
Existing laser anti-fake figure mark comes with some shortcomings in practice: conventional laser hologram similarly is to form by the mold pressing on polyester film of holographic nickel version, the format of the laser image of the laser anti-fake figure mark that this mode is made or pattern are very limited, can only be used for the identical fixed version pattern of printing of repetition.If the adulterator has obtained the pattern of these laser images, just can copy out very soon.Caused traditional laser anti-fake figure mark almost to lose anti-counterfeit capability thus.
It is false proof that common code anti-fake technology adopts the form of different number and figure to carry out, and as random digit, the consumer authenticates by input random digit after dialing the checking phone.But random digit self is without any anti-counterfeiting technology in this technology, so generally need to adopt the form that covers to cover random digit.This technology is complex procedures not only, and the form that covers almost do not have anti-counterfeit capability, and main anti-counterfeit capability is the telephone service system, but the technology content of telephone service system now is not high yet, and the adulterator has the ability to duplicate or copy fully.
Therefore the antifalse effect that improves the conventional laser anti-counterfeiting mark is technical issues that need to address.
Summary of the invention
The technical matters that the present invention solves provides a kind of variable graphic anti-counterfeiting method with laser holographic effect, the variable making of this method laser data, laser hologram image on the laser anti-fake figure mark that makes by this method has nothing in common with each other, has uniqueness, perhaps be also referred to as diversity, thereby have more excellent antifalse effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
The variable graphic anti-counterfeiting method that the present invention is designed with laser holographic effect, be to realize false proof by on carrier, forming hollow graphic units with laser holographic effect and diversity, this technology has not only guaranteed the uniqueness of graphic units, and graphic units self also has antifalse effect, and the imitator can't produce by common technology has laser holographic effect and can the random variation picture and text.Adopt in the anti-counterfeit package of this technology even need not graphic units is covered, the consumer directly can be by the true and false of naked eyes recognition unit picture and text, and the true and false of passing through phone and network inquiry picture and text that also can improve has the double anti-forge effect.
The imitator can't mainly contain the technology limitation of two aspects by the above-mentioned Antiforge of existing techniques in realizing, the first can't be printed the picture and text of variation by the mode of fixed version printing laser effect, each variation all will be made a plate again, and the mode of picture and text imitator's the fraud cost that makes especially remains high at random.It two is to print the printing technology of picture and text at random, as digital printing technology etc., and the printing ink that can only adopt black or redness etc. very to limit to, the color variation all can't realize, let alone the laser effect.The present invention has specifically adopted following steps in order to realize having the variable graphic of laser holographic effect:
