Description
Technical field
The present invention relates to infotech, automatic identification technology field, relate in particular to a kind of multiwave stero barcode and manufacture method and application.
Background technology
Bar code generally, only is to express by one deck pictorial symbol information in application process, be the information on a plane, and for bar code symbol, this has not only limited the content of bar code storage, also can't effectively resist the possibility that specific bar code symbol information is acquired simultaneously.
Summary of the invention
Purpose of the present invention is exactly in order to overcome the defective that above-mentioned prior art exists, a kind of can be used for false proof multiwave stero barcode and manufacture method and application to be provided.
Purpose of the present invention can be achieved through the following technical solutions: a kind of multiwave stero barcode, it is characterized in that, described stero barcode comprises two-layer bar code, this two-layer bar code is respectively the bar code of visible ink printing, the bar code of multiband ink printing, and the bar code of described visible ink printing is located at the bar code top of multiband ink printing.
A kind of method for making of multiwave stero barcode is characterized in that, this method may further comprise the steps:
(1) with default logical relation and the demand of information basis, form two bar codes in print system, these two bar codes are respectively the bar code that the multiband ink printing need need be used with the bar code and the lower floor of visible ink printing in the upper strata;
(2) adopt the digital ink-jet print system with the printing ink of different-waveband uniformly according to lower floor's bar code spray at dielectric surface, form the bar code that lower floor needs the multiband ink printing;
(3) bar code of multiband ink printing is dried;
(4) with digital printing system with visible ink uniformly according to the surface of upper strata bar code spray in the bar code of lower floor's multiband ink printing.
A kind of application of multiwave stero barcode is characterized in that, this application comprises:
(1) multiwave stero barcode is produced on dielectric surface;
(2) adopt the light source irradiation of the printing ink corresponding wavelength of the variant wave band that uses in lower floor's bar code to arrive dielectric surface, excite the printing ink of variant wave band to send visible light;
(3) after the recognition facility are accepted visible light, by the polarized light intercepting, will disturb light to filter, visible light is entered in the sensor of recognition facility;
(4) bar code of recognition facility Direct Recognition upper strata visible ink printing;
(5) by the demoder in the recognition facility, two-layer bar code is decoded respectively;
(6) information in the two-layer bar code is reduced according to default logical relation and demand.
Compared with prior art, the present invention has the following advantages:
(1), improved the ability that social data security guarantees for to have increased a kind of novel false proof means;
(2) and after two-dimensional bar code combines, more increased data can not naked eyes identification anti-counterfeit capability;
(3) and the bar code combination, strengthen the speed and the ability of data processing, improved service efficiency and accuracy;
(4) anti-counterfeiting technology cheaply is extensive use of easily;
(5) by the bar code information of different aspects, increase bar code memory contents and quantity of information;
(6) by the bar code information of different aspects, carry out association, improved the security of bar code memory contents;
(7) owing to need the participation of Different Light system, increased the difficulty that cracks.
Description of drawings
Fig. 1 is the synoptic diagram of the application of a kind of multiwave stero barcode of the present invention.
Embodiment
The present invention will be further described below in conjunction with specific embodiment.
Embodiment 1
As shown in Figure 1, the making of ultraviolet bar code and recognition methods are printed on nominal value with ultraviolet ink with a segment information in the process of work, after oven dry, on invisible barcode position, print red bar code again, and be attached on the carrier.Ultraviolet source emission ultraviolet light is to the surface of bar code, and excited ultraviolet printing ink sends visible light to the recognition facility, after the recognition facility are accepted light, intercept technology with ultraviolet filtering by polarized light, operational light is entered in the sensor of recognition facility, carry out the imaging decoding, read bar code information.Synchronously, by daemon software control, reader starts another and reads mode, after the bar code on surface is discerned, two segment informations is verified by algorithm, verify qualified correctly after, both shown the authenticity of this information.
The present invention adopts the stero barcode technology, and the bar code with ultraviolet ink and red ink printing has multiple disguise (naked eyes are invisible, and the duplicating machine difficulty is duplicated, and once can't obtain, and can't resolve after obtaining), and is false proof, wear-resisting; And can be, and realize the normal recognition of bar code by common bar-code reader by under the UV environment.Can be used for false proof, system paper money, controlled ticket issuing, government document, special industries such as certificate are used.
The more industrialized production of ultraviolet ink and red ink is used in system paper money industry, and its characteristic is very easy to be used for printing.But print bar code and but have bigger difficulty, key is that the characteristic of ultraviolet ink itself itself is colourless, so, need by the digital ink-jet printing technology, the bar code that will contain information, in print system, form bar pattern, with digital printing system with printing ink uniformly according to the bar code graphics spray at dielectric surface.
The identification range of existing conventional reader can't be responded to for ultraviolet source in red color spectrum range, therefore, if solve identification equipment, is the key in the key.By exciting of extraneous ultraviolet source, ultraviolet ink can be sent a large amount of visible lights, and like this, bar code can be seen by naked eyes clearly that its image also can be obtained by the recognition facility simultaneously.
When obtaining image, action of ultraviolet light is still arranged at facility, though because the ultraviolet light naked eyes can't be discerned, and it also has energy, therefore the formation to image forms interference, how to form distinct image.In the identification facility, to jamming light source, we have done the processing of polarized light.With the jamming light source elimination.Obtain available and interference-free image.
By the demoder in the recognition facility, bar code image is decoded, information is restored from bar code.
