Description
Technical field:
The present invention relates to a kind of antiforging printing method, especially a kind of complementary segmental stealth identifies 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.
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 complementary segmental stealth identification two-dimension code anti-counterfeit
Method, the method for anti-counterfeit one width is made of two-dimension code anti-counterfeit information image in 2 D code it is complementary be divided into two pieces or more polygons
Image after segmentation is divided into two parts by image, and first part's image after segmentation is printed on printed matter using common ink
In image in 2 D code area, match color ink for the second part image and first part's image complementation after segmentation using metamerism
It is printed in the image in 2 D code area of printed matter, shows first part in the image in 2 D code region of printed matter under visible light
The blank area profile of image and second part image, shows under infrared light by first part's image and second part image complementation
The complete former image in 2 D code of the width constituted, can identify the printed matters such as label, bill, marketable securities in this way is
It is no to there are problems that palming off infringement.
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 image in 2 D code complementation is divided into two pieces or more polygons
Image after segmentation is divided into first part's image and second part image two parts, first part's image after segmentation by image
All it is divided into two kinds with the color lump in the color lump figure of second part image, one is black color lump, another kind is white color lump,
First part's image after segmentation is printed in the image in 2 D code area on printed matter using common ink, after segmentation
Second part image be printed in the image in 2 D code area on printed matter using metamerism with color ink, for second part
White color lump in the color lump figure of image, it is desirable that under visible light with all show white under infrared light, utilize ordinary white ink
Printing, for the black color lump in the color lump figure of second part image, it is desirable that show white under visible light, shown under infrared light
Existing black is printed using above-mentioned metamerism with color ink, and therefore, image in 2 D code area shows first part's figure under visible light
Picture, image in 2 D code area shows by first part's image and the complete original two of a width of second part image construction under infrared light
Code image is tieed up, correct two-dimensional barcode information is obtained by scanning, the personation of label, bill, marketable securities etc. can be effectively prevented
And abuse.
