Description
Technical field
The present invention relates to a kind of method for anti-counterfeit of structural texture, particularly a kind of random grain is the structure grain anti-fake method of angular color change fiber.
Technical background
The method for anti-counterfeit of structural texture is to utilize the randomness of random grain to carry out false proof, but a critical defect of original grain anti-fake method is, during naked eyes identification, the existing printing of the visual signature of random grain (containing thermoprint) mode itself all can be imitated, this threat has caused the inefficacy of grain anti-fake method, often to observe or choose filament and distinguish whether be that printing is imitated as a kind of means that remedy by high magnified glass with pin is destructive, this has brought grievous injury for the effect of grain anti-fake method, particularly be coated with on the packing of plastic foil on some top layers, tobacco bale for example, wine box packing, it is then more difficult to distinguish true and false fiber, observes unless will pack comprehensive extraction filament that destroys.
The random distribution characteristic of fiber pattern is that impersonal force can be, can not repeat (or very expensive repetition), the visual signature of fiber pattern imitates easily if can be printed ink marks, the random distribution characteristic of its fiber pattern just can be printed imitation easily, although the distribution of the fiber pattern of every piece of sign is at random, every difference, but existing variable data (variable image) printing technology can very low-cost imitation, do not have a kind of simple, nondestructive this imitation of going to distinguish, the antifalse effect of that structural texture can be had a greatly reduced quality so that lost efficacy.
The process of announcing structure grain anti-fake method among the Chinese patent CN99801139.1 " method for anti-counterfeit of structural texture " has in detail also related to various feature textures, but its feature texture all can not solve the defective of the visual signature imitation of existing printing vestige.
Summary of the invention
The method for anti-counterfeit that the purpose of this invention is to provide a kind of structural texture, it only can solve with naked eyes just can distinguish the counterfeit of printing fine line whether easily.
The object of the present invention is achieved like this:
A kind of method for anti-counterfeit of structural texture, anti-counterfeiting mark 1 is encoded, one or more codings 2 that only belong to it are set on a sign, be distributed with random grain 3 on the anti-counterfeiting mark 1, together store in database in conjunction with coding 1 random character of the random grain on the anti-counterfeiting mark 23, transfer this random grain feature for the consumer and verify the true and false, it is characterized in that: described random grain 3 is angular color change fiber 4.
The mode of transferring can be multiple, for example call voice description, fax, SMS or multimedia message picture, internet etc.
Anti-counterfeiting mark is attached on the false proof product of concrete needs.

The part surface of described coloured angular color change fiber 5 is presented on the surface of described anti-counterfeiting mark 1, the part surface of described coloured angular color change fiber 5 has concavo-convex barrier structure, be distributed with at least two colors (containing colourless and white) on it, described at least two colors have tangible vision difference on the part surface of described coloured angular color change fiber 5, make when on anti-counterfeiting mark 1 surface, observing the part surface of described coloured angular color change fiber 5 from different perspectives, can see different colors respectively.Because vision difference of the present invention is to be blocked by concaveconvex structure by the color character that distributes on the pars fibrosa surface in the anti-counterfeiting mark to cause, it is a kind of spatial structure, in any case and printing technology accurately also can't be counterfeit goes out this spatial structure, so the present invention can effectively stop the counterfeit of printing technology.
Described coloured angular color change fiber 5 has multiple version at least, comprises all various concrete structures of the inventor in patent documentation CN1782232 at least.
Further, described angular color change fiber 4 is a fluorescence angular color change fiber 6, when can tangible vision difference being arranged illuminant colour with uviol lamp during from the described fluorescence angular color change of different angular illumination fiber 6.These vision differences can be to become blue-light-emitting by emitting red light, also can be that emitting red light disappears.
Described fluorescence angular color change fiber 6 has at least two material parts that distribute and extend in parallel along the fibre length direction jointly at least on the xsect on a certain section on the single fluorescence angular color change fiber 6; These materials partly have different light characteristics, and at least two materials part makes in the distribution of xsect and forms the barrier structure that can partly or entirely block exciting light between these two materials parts, make to have two irradiating angle A and B on the described anti-false fiber at least, when exciting light has when irradiating angle A shines and visibly different visual effect when irradiating angle B shines.Human eye moves and only needs the exciting light sources angular transformation just can be observed the variation of fluorescence angular color change fiber 6 illuminant colours not doing, and this is that printing-ink is to imitate.After fluorescence angular color change fiber 6 is distributed in anti-counterfeiting mark, change the irradiating angle of exciting light, the eye-observation angle need not change the marked change that just can observe illuminant colour.
Further, described fluorescence angular color change fiber 6 has multiple version, comprises all various concrete structures of the inventor in patent documentation CN101135127 at least.
Because the angular color change visual effect is by the decision of the spatial structure of fibre section, and the plane characteristic of printing ink marks just can not be realized this spatial structure of fiber on mechanism, thereby has reached the purpose that prevents fiber in the printing fine line imitation paper.
Further, also be attached with on the described anti-counterfeiting mark 1 coloured angular color change safety line 10 or (with) fluorescence angular color change safety line 11.
Further, also be attached with on the described anti-counterfeiting mark 1 coloured angular color change safety line 10 or (with) fluorescence angular color change safety line 11 part that also can be used as the textured fibres feature is stored in the database, the anti-counterfeiting mark that not only increased of coloured variable color safety line 10 not only prints and can not imitate, and its calibration as the random grain position feature makes and become more difficult when the fake producer may directly use the mode of putting fiber counterfeit.
Further, the relative position of above-mentioned safety line on anti-counterfeiting mark is at random, and this feature is as long as slight swing just can realize in the safety line wiring.
The xsect of described coloured angular color change safety line 10 has multiple version, comprises that at least the inventor has the concrete structure of the various xsects of flat fiber in patent documentation CN1782232.
The xsect of described fluorescence angular color change safety line 11 has multiple version, comprises that at least the inventor has the concrete structure of the various xsects of flat fiber in patent documentation CN101135127.
The invention effect
Effect of the present invention is conspicuous, it can be stopped any mode of printing the visual signature at random of random grain is directly imitated, particularly when having plastic sheeting to cover, be true fiber or printing fine line also can be nondestructive difference easily, from but the counterfeiter can not imitate this random distribution characteristic.
