Description
Technical field
The present invention relates to anti-counterfeiting technology, particularly relate to a kind of anti-fake material and preparation method thereof.
Background technology
In existing skill counterfeit-proof tech, greatly mainly with the body and random distribution etc. of watermark, colored fibre, fluorescent ink printing, micro-point or small mark as counterfeit protection measures.
Such as, prior art 1, Chinese patent literature CN102108653A, disclosed a kind of sheet anti-fake material, described sheet anti-fake material adopts the polymorphic structure beyond square; And described sheet anti-fake material is made up of following layer structure: the false proof carrier layer of papery, the false proof carrier of wherein said papery is the paper obtained by least two kinds of composite manufactures of fiber; And false proof layer.Also disclose the preparation method of described sheet anti-fake material and the cheque paper containing this sheet anti-fake material.Sheet anti-fake material of the present invention can obtain possesses the multi-level anti-fraud functional cheque paper such as naked eyes identification, fast machine-readable, analysis expert simultaneously.
For another example, prior art 2, Chinese patent literature CN104610812A, disclosed fluorescence silicon nano particles, as the application of anti-fake mark, prepare fluorescence silicon nano particles by silicon source, the fluorescence silicon nano particles obtained are used as anti-counterfeiting ink to prepare security pattern.Because nano silicon particles has good photoluminescent property, quantum yield is high, and storage stability is good, has good excitation wavelength dependence, and the security pattern of preparation can show the light of different colours under the illumination of different excitation wavelength, can play good antifalse effect.
For another example, prior art 3, Chinese patent literature CN101673341A, disclosed in the present invention relates to anti-counterfeiting technology, particularly relate to a kind of anti-counterfeiting method of micro-points.The method comprises the following steps: (1) provides a kind of micro-point; (2) provide a kind of glue, micro-point is mixed among glue; (3) the mixed atomarius glue of point on carrier; (4) solidified glue; (5) glue of taking pictures drips, and forms original Contrast's picture; (6) original Contrast's picture is stored in background data base; (7) fake certification glue of taking pictures drips, and is formed by than picture; (8) read background data base original Contrast picture, compare with by than picture, make the true and false and judge; Wherein, the glue of taking pictures described in (5) step drips, and takes pictures for amplifying; Fake certification described in (7) step glue of taking pictures drips, and is also to amplify to take pictures.The invention provides the not imitability anti-counterfeiting method of micro-points of one.Corresponding, Chinese patent literature CN102267287A discloses a kind of preparation method of similar a kind of micro-some anti-counterfeiting stamp and and realizes the device of the method.The preparation method of micro-some anti-counterfeiting stamp comprises the following steps: S1, provides a kind of micro-some label, provides a kind of ink; S2, mixed ink, mixes with ink by micro-some label; S3, provides at least two shower nozzles, provides object; S4, sprays, by shower nozzle, the ink being mixed with micro-some label is sprayed to subject matter; S5, drying is mixed with the ink of micro-some label; In course of injection, mixed black step is carried out continuously, mixes ink, completes in totally enclosed fluid path to shower nozzle ink supply, injection.The invention provides in a kind of process the preparation method being not easily mixed into the micro-some anti-counterfeiting stamp that impurity, the in real time micro-point of maintenance are evenly distributed in ink and the device realizing the method.
For another example, prior art 4, Chinese patent literature CN1350274A, disclosed a kind of anti-fake mark containing most small mark or pattern and forming method thereof, with the anti-fake mark containing most micro pattern mark, reach the application identified article genuine-fake and prevent from forging.Object qualification method is at least one unique tag according to being formed in object, it contains most micro pattern or mark, and close in mark in the mode of random combine, with as a comparison, qualification method, and have prevent other people from forging and can reach easily identify and qualification and contrast effect.
But, enumerate such as, the body and random distribution etc. of the composite fibre of prior art, fluorescence silicon nano particles, micro-point or small mark are as counterfeit protection measures, it is not the effect that can prevent other people from forging like that to open text narration, along with the progress of science and technology, these technological means all can be cheap imitated, the background data base only had described in prior art 3 that can not copy, but back-end data is also dangerous, the database of enterprise is easy to suffer assault, and need communication security guarantee, still undesirable.Thus, the anti-fake material of prior art and counterfeit protection measures all have potential safety hazard more or less, need constantly to weed out the old and bring forth the new, constantly progress.
