Photoetching technique etc. can produce or form the method for the optical grating construction of different angle and frequency.
Meanwhile in order to improve the aesthetics of hologram, also it can be nested with other anti-counterfeiting technologies spy in digital watermarking hologram
Sign or grating microstructure information, application process are not limited to the separation of figure block, or the pixel filter point of various allocation proportions separates, or
It is superimposed the method for more optical grating constructions.
Specifically, hologram is made up of the grating fringe of the different frequency different angle of concavo-convex relief type under microcosmic,
After hologram with watermarked information is generated using the method for the invention, on photoetching hectograph represented by hologram recorded
Micro-structural striped, because photoetching hectograph is highly brittle weak, be easily damaged, can not batch duplicating, therefore by micro-structural on photoetching hectograph
Striped is solidificated on wear-resistant reusable hard metal material.
Generally the metal form containing above-mentioned micro-structural striped, or radium-shine template are obtained by way of spraying silver, electroforming.
Specifically, including following technical process：
1st, one layer of silver conductive layer is formed in photoetching hectograph hologram surface with the method for chemical silvering, makes it conductive.
2nd, using the photoetching hectograph for having silver conductive layer as negative electrode, it is put into the electrolyte containing nickel ion, is electroplated using electrolysis
Principle, metallic nickel is plated on the silver layer of negative electrode and deposits to certain thickness.
3rd, the version for depositing to certain thickness nickel metal is taken out, takes glass plate off, wash the photoresist on metallograph top layer off, just
Obtain a hologram metal matrix for carrying mirror image pattern.
4th, it is same, hologram metal form is put into electroforming apparatus as negative electrode again, mirror image can be obtained again
Two substituting metal templates, by that analogy it is reproducible go out generation after generation of descendants metal matrix.
Hologram pattern is turned into imprinting and copying on various plastic materials with such metal matrix can, just obtains holography
Product, i.e. anti-fake product or antifalsification label.
Antifalsification label, generally radium-shine packaging material, by entering to the antifalsification label are generated by the method for the invention
Row identification, can take precautions against piracy.Specific identification process is as follows：
The optical information of hologram diffraction on antifalsification label is gathered, the holographic data according to corresponding to obtaining the optical information.Its
Middle holographic data refers to the grating fringe frequency and grating angle value of each pixel.Obtained according to default corresponding relation list
View data corresponding with holographic data, wherein view data refer to the gray value of pixel.Pass through self-defined one default pair
Relation list is answered, grating angle value and gray value are made into corresponding relation, obtain the gray value of each pixel.Using preset algorithm
The gray value is calculated, watermark feature value is obtained, compares whether the watermark feature value matches with default watermark information, when described
When watermark feature value matches with the default watermark information, watermark correct information is fed back.
Invention additionally discloses a kind of antifalsification label, generated using the above method.
The present invention is combined watermark information with hologram, the gray value by watermarking images and the grating angle for photoetching
Value is corresponding, shows hiding information in the micro-structural of holography so as to realize, has both protected aesthetics and the brightness of hologram,
Avoid disturbing the recognition of watermark information in hologram, solve the limitation of both connected applications in the prior art, extend number
The application of word watermark, while add a kind of composite holographic anti-counterfeiting technology.
It should be noted that the content such as information exchange, implementation procedure in the present apparatus between each module and the above method are real
Apply example and be based on same design, particular content can be found in the narration in the inventive method embodiment, and here is omitted.
It should be noted that above-described embodiment can independent assortment as needed.Described above is only the preferred of the present invention
Embodiment, it is noted that for those skilled in the art, do not departing from the premise of the principle of the invention
Under, some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
