Description
Technical field:
The present invention relates to a kind of anti-counterfeiting printing technology, especially a kind of infrared stealthy complementary identification dimension code anti-counterfeit method can be with
For the anti-fake of various printed matters.
Background technique:
Method for anti-counterfeit relatively common at present has following several: the first is laser anti-false sign, with laser recessiveness ink fluorescent
The symbol of product or special identification icon are printed to the anti-fake label of product by ink-printing techniques, and same class product uses
Same labeling, because anti-fake label is easier to forge, and the anti-fake label forged is used on fake products, causes product
It is true and false to obscure, it is accordingly difficult to effectively anti-fake.Second is cipher counterfeit-proof labeling, and used method is that every product compiles one group
The coding of number, every product is different from, this number is printed on labeling and is covered, while can by this number deposit
For when consumer buys product, the number in mark is passed through phone or the meter that networks in the Computer Database of consumer query
Digital entering computer database in mark is compared identification by calculation machine, and identical is true, difference as vacation, method letter
Single, identification is easy, and is not easy to forge, but in actual use, prints labeling after generating because coded data is that computer is unified.It represents
The true and false coded data of product may be illegally duplicated fraud, meanwhile, the coding that coding also can be recycled on the product that do not inquire makes mark
And be attached on false pain product, antifalse effect it is difficult to ensure that.The third is texture anti-fake, anti-fake with the textural characteristics on its labeling, though
Right more difficult forgery, but the serial number due to being only marked with patch, and be plain code, every piece of mark can be inquired repeatedly, and fake producer can pass through warehouse
Phenomenon is copied the presence or absence of in the necessary textural characteristics i.e. grid reflected when administrator or shop-assistant are by serial number and inquiry on labeling
It is forged after attacking by this feature batch.4th kind is that metameric ink is anti-fake, and anti-fake metameric ink is based on metamerism
Identical color is presented using two kinds of substances in the anti-counterfeiting printing technology of phenomenon under a kind of light source, but under another light source,
But the phenomenon that presentation different colours, is realized anti-fake, but the ratio of metamerism is easier to measure, therefore antifalse effect is also difficult to
Guarantee.
In conclusion existing method for anti-counterfeit all has some disadvantages, thus cannot be from preventing fake products at all.
In conclusion existing method for anti-counterfeit all has some disadvantages, thus cannot be from preventing fake products at all.
Summary of the invention:
In order to overcome existing various printed matter anti-counterfeiting printing technologies there are the shortcomings that, the present invention is anti-for existing printed matter
Deficiency existing for pseudo- printing technology improves the prior art, proposes a kind of infrared stealthy complementary identification two-dimension code anti-counterfeit
Method, the antiforging printing method one width is made of two-dimension code anti-counterfeit information image in 2 D code it is complementary be divided into two parts, point
First part's image and second part image after cutting can be complementary the complete former image in 2 D code of one width of composition, and will segmentation
First part's image afterwards is printed on the side in the image in 2 D code area on printed matter using common ink, by second after segmentation
Parts of images is printed on the other side in the image in 2 D code area on printed matter using metamerism with color ink, exists under visible light
Image in 2 D code region on printed matter can only show the blank area profile of first part's image and second part image, only exist
The width being made of first part's image and second part image complementation completely former image in 2 D code can just be shown under infrared light,
The printed matters such as label, bill, marketable securities can be identified in this way with the presence or absence of personation infringement problem.
The technical solution adopted by the present invention to solve the technical problems is: adjust yellow black four color ink of green product matches color ratio
Example generates a kind of metamerism with color ink, should show under visible light white with color ink, and show black under infrared light,
A width image in 2 D code is made of two-dimension code anti-counterfeit information, and the image in 2 D code is divided into two parts, first after segmentation
Color lump in the color lump figure of parts of images and second part image is all divided into two kinds, and one is black color lump, another kind is white
Color lump,
First part's image after segmentation is printed on using common ink to the side in the image in 2 D code area on printed matter, will point
Second part image after cutting is printed on the other side in the image in 2 D code area on printed matter using metamerism with color ink, right
White color lump in the color lump figure of second part image, it is desirable that under visible light with all show white, therefore under infrared light
White color lump in the color lump figure of two parts of images is printed using ordinary white ink, in the color lump figure of second part image
Black color lump, it is desirable that show white under visible light, show black under infrared light, therefore printed using above-mentioned with color ink
Brush, therefore, image in 2 D code area shows first part's image under visible light, the first part of image in 2 D code area under infrared light
Image and second part image could display simultaneously, and constitute the complete image in 2 D code of a width.
In truth identification, first part's image and second part image display simultaneously under infrared light, and constitute
The complete image in 2 D code of one width, is obtained by scanning correct two-dimensional barcode information, and label, bill, valuable can be effectively prevented
The personation and abuse of security etc..
Detailed description of the invention
The following further describes the present invention with reference to the drawings.
Fig. 1 image in 2 D code.
Fig. 2 first part image.
Fig. 3 second part image.
The color lump figure of Fig. 4 first part image and second part image.
Specific embodiment
In Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the color matching ratio of yellow black four color ink of green product is adjusted, a kind of metamerism is generated
With color ink, white should be shown under visible light with color ink, and show black under infrared light, be made of two-dimension code anti-counterfeit information
One width image in 2 D code 1, and the image in 2 D code 1 is divided into two parts, first part's image 2 and second part after segmentation
Color lump in the color lump figure of image 3 is all divided into two kinds, and one is white color lump 4, another kind is black color lump 5,
First part's image 2 after segmentation is printed on using common ink to the side in the image in 2 D code area on printed matter, it will
Second part image 3 after segmentation is printed on the another of the image in 2 D code area on printed matter with color ink using metamerism
Side, for the white color lump 4 in the color lump figure of second part image 3, it is desirable that under visible light with all show white under infrared light,
It is printed using ordinary white ink, for the black color lump 5 in the color lump figure of second part image 3, it is desirable that show under visible light
Existing white, shows black under infrared light, using metamerism with color ink printing, therefore, image in 2 D code under visible light
Area shows first part's image 2, and first part of image in 2 D code area image 2 and second part image 3 could be same under infrared light
When display, and constitute the complete image in 2 D code 1 of a width.
In truth identification, first part's image 2 and second part image 3 display simultaneously under infrared light, and structure
At the complete image in 2 D code 1 of a width, it is obtained by scanning correct two-dimensional barcode information, label can be effectively prevented, bill, have
The personation and abuse of valence security etc..
