Description
Technical field
The invention belongs to the anti-counterfeit recognitions of information inquiry class and anti-counterfeiting printing technology field, and in particular to a kind of color transfinites
（It is i.e. very more）Code anti-false method and printed article.
Background technology
" the color code of dynamic distinguishes color method for anti-counterfeit to Chinese patent application（CN102663973A）" disclose a kind of anti-fake side of color code
Method, it is in anti-fake label（Printed article）Upper colored security code of the setting with multiple color, by anti-fake checking device to consumption
Person confirms the correspondence of the value and color change arrayed feature of colored security code, for the true and false of consumer authentication product.It should
Method for anti-counterfeit is substantially still a kind of artificial digital false-proof technology, still not anti-thief in the family.
《China Youth News》On June 4th, 2009 exists《Economic special issue》Deliver full page article --- national code anti-fake pushes away
It extensively takes action noiseless lower the curtain.Four big loopholes of code anti-fake are the article pointed out, the three of loophole fakes to steal code batch：It " obtains close
The gimmick of code can be a variety of, for example, can not rule out fraud group bribes internal work personnel with money, obtain code and fake
Possibility, or hacker master-hand is employed to swarm into anti-fake network identification system database, a large amount of anti-fake data of copy from internet
It (anti-counterfeiting characteristic information) and then forges without restraint.It need to be noted that be：Digital code anti-false is with anti-fake network identification system data
Premised on being perfectly safe of library, once leakage of data, anti-counterfeiting system engineering will put to rout all along the line.It is well known that the peace of internet
Entirely, have become one need worry the problem of.The carelessness of company management's link, high-tech perspective instrument scan and obtain password etc.
Deng and one of possible method ".In conclusion the three of the loophole of existing code anti counterfeiting technology be that a thief within a house is hard to guard against, internal work
As long as personnel's copy steals the anti-counterfeiting characteristic information put on record in database, being sold to fake producer can fake in batches easily, and
It can not differentiate the true and false.
In conclusion there are one common loophole --- a thief within a house is hard to guard against for the digital false-proof technologies such as existing code tool.This be because
For the anti-counterfeiting characteristics information such as anti-counterfeiting characteristic random number code, character color, random figure on existing code anti-fake marker is
The mimeograph documents generated in computer in advance, ink distribution characteristics made of being printed out through digital printer.So, interior
As long as portion staff or network hacker, copy steal the original anti-counterfeiting characteristic letter such as random number code, character color, random figure
Breath, so that it may print out same ink distribution characteristics with digital printer.
In other words, the anti-counterfeiting characteristic of existing code anti-fake mark is entirely derived from the original anti-counterfeiting characteristic letter designed in advance
Cease, be original anti-counterfeiting characteristic information printout conclusion, as long as copy steal the i.e. reproducible puppet of original anti-counterfeiting characteristic information
It makes.And for print production, in order to inquiring and authenticating it is true and false, the features such as random number code, character color, random figure it is original anti-fake
Characteristic information is necessarily required to relevant staff and handles, and is necessarily required to completely be stored in anti-fake network identification system database
In, so, internal work personnel or the hacker copy that necessarily has an opportunity steal original anti-counterfeiting characteristic information, therefore, existing
The loophole of three " a thief within a house is hard to guard against " of code anti counterfeiting technology loophole, is just difficult to avoid that.
The color of printed matter is very rich and varied, and printable color out has thousands of kinds.PANTONE (Pan is logical) state
The printing series GP1201CU cards of border colour atla have 1170 kinds of colors and its a color number, textile garment TPX colour atlas have 1925 kinds of colors and
Its color number, plastic cement have 1700 multiple colors and its color number, four-color process to have 3000 multiple colors and its color number.
The characteristics of field printing：The entire space of a whole page is all covered with a kind of ink of color.Field printing mass colour is thick and solid, fresh
It is gorgeous, there is class sense.Field printing realizes that space of a whole page color is identical as ink colors used by spot color printing technique.State
Inside and outside common field printing equipment is 7 color printing machines, and uncommon field printing equipment is 12 color printing machines, rare
Field printing equipment be 16 color printing machines, more than 18 colors the printing machine country there is presently no.
The characteristics of net-point printing：A kind of printed patterns of color be with the different ink site of other multiple colors side by side or
Intersection combination is formed（It is commonly called as " synthesizing "）.The color of printed patterns（Human eye vision effect）With the color of ink used not phase
Together.With amplification sem observation, it can be seen that the different ink site of some colors.Most common printing technology is 4 color nets on the market
Point printing, printing technology are simple, quick.Uncommon printing technology is 7 color net-point printings on the market.Currently, number both domestic and external
Code chromatic printing machine be up to 7 color printing machines, more than 8 colors the color digital printer group country there is presently no.
The distinguishing characteristics of field printing and net-point printing：Field printing can't see ink site, and net-point printing then may be used
To see the ink site/cable of many a variety of colors.
Invention content
An object of the present invention：There is provided one kind transfinites color code anti-counterfeiting method, to block the digital code anti-false of " a thief within a house is hard to guard against "
Technical leak.
The second object of the present invention：There is provided one kind transfinites color code Antiforge printed matter, anti-with the number for blocking " a thief within a house is hard to guard against "
Pseudo- technical leak.
The present invention transfinite color code anti-counterfeiting method technical solution it is as follows.
One kind transfinites color code anti-counterfeiting method, including each printed article (1) is given to publish at least one volume with uniqueness
Code (2), it is characterised in that include the following steps：
1. configuring the field printing color lump (3) of n kind colors to each coding (2)；Wherein, n >=8 or 10 or 15 or 22 or 29 or
36 or 43 or 50 or 57 or 64 or 71 or 78 or 85 or 99；Why n >=8 are required, is because commercially available digital printer is most
For 7 colour cells, 7 colors such as one group of black, one group red, one group of yellow, one group of blue, one group orange, one group of purple, one group of green
Group；After being arranged in this way, when fake producer replicates 8 kinds or more field printing color lump (3) of color using commercially available digital printer, until
Few palpus chromatography is primary（It as the saying goes print twice）；The personation color lump that this time is beaten is when examining, the examination of computer anti-fake network
System software will necessarily find that the relative position error between some personation field printing color lumps (3) that time is beaten is more than
0.01mm will provide the conclusion that discriminating is false；It can be seen that when the numerical value of n is bigger, fake producer must just use multiple
（Even ten several times）The method de-duplicate beaten is covered to fake；Researches show that：As n >=8, two-shot chromatography, which replicates to fake, is difficult to success,
As n >=15, chromatography three times replicates hardly possible success of faking, and as n >=22, it is absolutely not that four chromatographys replicate fraud
Success；
2. the color characteristic information (such as color number etc.) and precise position information of field printing color lump (3) (such as are accurate to
0.01mm or so/using the resolution ratio record position information of 1200dpi or so) collect, encode (2) with it deposits for index code
In deposit case to computer anti-fake network checking system database, as personal characteristics news file；Wherein, exact position feature
Information is to be accurate to the location information of 0.01mm or 0.035mm or 0.05mm；
3. consumer checks the true and false, coding (2) is acquired with the shooting mobile phone (4) of resolution of lens >=800 or 20,000,000 pixels
Field printing color lump (3), to obtain field printing color lump (3)（Color characteristic information and exact position characteristic information etc.）
Information (5) to be checked；
4. information to be checked (5) is uploaded to computer anti-fake network checking system；
5. by the color characteristic information to be checked of field printing color lump (3) included in information to be checked (5) and exact position to be checked
Information is believed with the color characteristic information of the field printing color lump (3) for record of putting on record in personal characteristics news file and exact position
Breath（In client server）It is matched；It is really to differentiate conclusion presentation of information to taking pictures by coding (2) if being consistent
On mobile phone (4) screen；If not being consistent, will encode in the discriminating conclusion presentation of information to shooting mobile phone (4) screen that (2) are false.
It is appreciated that the color code anti-counterfeiting method that transfinites, it is characterised in that include at least one of following.
1. the color to be checked that consumer is acquired to field printing color lump (3) included in the information to be checked (5) obtained is special
Reference breath is tested, if there is ink site, it is that false discriminating conclusion presentation of information is shielded to shooting mobile phone (4) that will encode (2)
On curtain.
2. the accurate position to be checked of field printing color lump (3) included in the information to be checked (5) that consumer's acquisition is obtained
Confidence breath is tested, will if the site error of some field printing color lumps (3) is more than 0.01mm or 0.05mm or 0.10mm
Coding (2) is in false discriminating conclusion presentation of information to shooting mobile phone (4) screen.
3. field printing color lump (3) is equipped with delustring transparent surface layer (6) above；Or field printing color lump (3) uses flatting oil
Ink system.
4. the color of field printing color lump (3) is using one or more in three primary colors red, yellow, blue；
Why in this way, being to have two groups of print cartridges, i.e. black ink box one, color ink because normal printer is all four colors
One group of box, the colored ink primary colors for including four kinds of colors such as red, yellow, blue.After being arranged in this way, fake producer is using common
When printer print copy field printing color lump (3), the personation field printing color lump (3) of print copy is not necessarily face on the spot
Color, but the color lump with site/cable.When inspection, computer anti-fake network checking system will necessarily find that it has ink net
Point is not on the spot, to necessarily provide the conclusion that discriminating is false.
5. the gap (7) of random interval -0.1mm~0.3mm between adjacent block；Here why there is negative, be table
Show between adjacent block the situation that edge is overlapping occur.
6. being less than the printing machine of n groups using colour cell, going to complete the printing of printed article (1) by chromatography at least once.
7. the size of single field printing color lump (3) is 0.05mm × 0.05mm~2mm × 2mm.
It is appreciated that the color code anti-counterfeiting method that transfinites, it is characterised in that include at least one of following.
1. the color to be checked that consumer is acquired to field printing color lump (3) included in the information to be checked (5) obtained is special
Reference breath is tested, if there are many ink site of color, be not monochrome/spot color, will encode the discriminating conclusion that (2) are false
In presentation of information to shooting mobile phone (4) screen；Why conclude in this way, is because the field printing color lump (3) in master is single
The monochrome of color, e.g. spot ink printing, and duplicate is then a variety of primary inks sites side by side or intersection combination is formed
Secondary color or secondary color.
2. consumer to be acquired to the accurate position to be checked of field printing color lump (3) included in the information to be checked (5) obtained
Confidence breath is tested, will if gap (7) width error between adjacent block is more than 0.01mm or 0.05mm or 0.10mm
Coding (2) is in false discriminating conclusion presentation of information to shooting mobile phone (4) screen.
The present invention transfinite color code Antiforge printed matter technical solution it is as follows.
One kind transfinites color code Antiforge printed matter, at least publishes that there are one volumes with uniqueness on each printed article (1)
Code (2)；Coding (2) storage is put on record in computer anti-fake network checking system database；It is characterized in that：
1. each coding (2) is configured with the field printing color lump (3) of n kind colors；Wherein n >=8 or 10 or 15 or 22 or 29 or
36 or 43 or 50 or 57 or 64 or 71 or 78 or 85 or 99；
2. the color characteristic information of field printing color lump (3) and precise position information shooting, collecting are got off, encoding (2) with it is
Index code storage is put on record into computer anti-fake network checking system database, as personal characteristics news file for consumer
Check the true and false.
It is appreciated that the color code Antiforge printed matter that transfinites, it is characterised in that include at least one of following.
1. field printing color lump (3) is equipped with delustring transparent surface layer (6) above；Or field printing color lump (3) uses flatting oil
Ink system.
2. the color of field printing color lump (3) is using one or more in three primary colors red, yellow, blue.
3. the gap (7) of random interval -0.1mm~0.3mm between adjacent block；Here why there is negative, be table
Show between adjacent block the situation that edge is overlapping occur.
4. the size of single field printing color lump (3) is 0.05mm × 0.05mm~2mm × 2mm.
Coding (2) of the present invention, refers to various codings, either Arabic numerals, can also be primary and secondary character,
It can also be the one-dimension code and Quick Response Code of graphic form.Such as sequence number, bar code, Quick Response Code, date of manufacture, anti-fake electricity
Code, anti-channel conflict coding, commodity are traced to the source code, it is preferable to have uniqueness, randomness, it is comprising query link network address, non-plus
Close Quick Response Code.
Field printing color lump (3) of the present invention is a kind of color lump of no printing net-point/cable, it uses spot color printing
Technique is formed.Each field printing color lump (3) is preferably a symbol in Quick Response Code.Symbol is to constitute the square of QR codes
Point.Such as the QR codes of version 2 are made of 25 × 25 symbols, a symbol is generally 0.5mm.
Shooting mobile phone (4) of the present invention is also known as smart mobile phone.
Information to be checked (5) of the present invention includes photochrome to be checked.
The two-shot chromatography error professional standard of the precision printing machinery such as existing offset press, flexible printing press, colored digital machine is just
Negative 0.15mm.Why two-shot chromatography error is necessarily led to, and odjective cause is：1, the printable fabrics such as paper, film (3) are by temperature
Degree, mechanical stretching, unreels the influence of the factors such as contraction at humidity, necessarily material is caused to deform；2, mechanical run necessarily leads to chromatography not
It is accurate.In other words, two-shot chromatography generates positive and negative 0.15mm errors and is inevitable, and is the objective reality that can not be eliminated.In view of
This, n >=8 are just deliberately arranged in the present invention, to force fake producer two-shot chromatography must be used to fake, with fault in enlargement numerical value, enhancing
The accuracy of software identification.
It facts have proved：When the numerical value of n is more than the colour cell element number of printing machine, fake producer must just use multiple（Very
Several times to ten）The method de-duplicate beaten is covered to fake.Researches show that：As n >=8, set beat duplication fraud can not possibly succeed, when n >=
When 10, set plays the hardly possible success of duplication fraud, and as n >=15, set plays duplication and fakes can not possibly succeed completely；When n >=22
When, set plays the absolutely not success of duplication fraud.
Compared with existing digital false-proof technology, the present invention can generate following advantageous effect.
One, identification are simple, and computer anti-fake network checking system software can automatically be provided in relation to the accurate of commodity true and false
Differentiate conclusion.
Secondly, replicate fraud difficulty and increase substantially, bigger duplications of n numbers is faked and is more difficult to, absolutely not after n >=22 to make
Vacation success differentiates that conclusion accuracy rate increases substantially.
Thirdly, the present invention dexterously pass through many not homochromy numbers of setting field printing color lumps (3) method, namely utilize
N is more than existing printing machine color cell quantity（Generally 7 groups）Method, force fake producer can not one-step print complete, must
It must repeatedly chromatography replicate, utilization is unavoidable（Machinery）Chromatography error is discerned the false from the genuine, to having blocked " a thief within a house is hard to guard against "
Digital false-proof technology loophole.
Four, popularization and application of the invention necessarily improve the application effect of digital false-proof technology, and the public is subjective can be actively
Antiforge inquiry is carried out, Antiforge inquiry rate will necessarily be greatly improved, therefore, commodity circulation is objectively had collected by antifake examining system
With sale dynamic etc. commodity retails big data, to development Chinese commodity big data industry it is highly beneficial.

Specific implementation mode
To enable the above objects, features and advantages of the present invention to be clearer and more comprehensible, the present invention cited below particularly is comprehensive preferred real
Example is applied, and attached drawing is coordinated to be described in detail.
Embodiment one.
As shown in Figure 1, Figure 2, Figure 3 shows, with the 80g/m of A3 specifications2Art paper has 20 with the printing of seven color digital printers of HP
The label of color on the spot is planted, and coding (2) a --- Quick Response Code with uniqueness is published to each label.
Since seven color digital printers of HP only have 7 colors, the label of 20 kinds of colors on the spot must print 2 times 1 time, chromatography
It can complete.
As shown in Figure 1, forming 7 kinds of colors after the first printing（It is not shown）One of color code block (8).
As shown in Fig. 2, first time chromatography (i.e. the second printing) forms other 7 kinds of colors afterwards（It is not shown）The areas Cai Ma
Two (9) of block.It is emphasized that must first replace the ink of other 7 kinds of colors after the first printing, could start to print color code
Two (9) of block.
As shown in figure 3, second of chromatography (i.e. the third printing) forms other 6 kinds of colors afterwards（It is not shown）The areas Cai Ma
Three (10) of block.It needs exist for, it is emphasized that must first replace the ink of other 6 kinds of colors after the second printing, to start to print
Three (10) of the color code block of brush.
By one-step print plus two-shot chromatography（Repeated multiple times chromatography）Afterwards, just can as play picture arrangement game, be combined into as
Coding (2) --- Quick Response Code shown in Fig. 3, with 20 kinds of colors on the spot can visually be referred to as super color code here or surpass
The color code of limit.
The printable fabrics such as studies have shown that paper, film are necessarily stretched and are loosened repeatedly in printing process, therefore inevitable
Generate unavoidable dilatation.Domestic and international most accurate printing machine at present, two-shot chromatography error is also all in positive and negative 0.15mm
More than.For example, necessarily leading to ghost image as shown in figure 12 after same group of coding (2) two-shot chromatography（That is two-shot chromatography error causes
Ghost image）.
Prepare a technical grade optic micro distance camera lens and digital camera, by the field printing color lump (3) in coding (2) into
Row bust shot, to obtain its photochrome；Then the photochrome of shooting acquirement, corresponding coding (2) information are stored together
Put on record into computer anti-fake network checking system database, as personal characteristics information, in case the public checks the true and false.

Field printing color lump (3) frame line --- two (9) of color code block of additional around the Quick Response Code of color.
In order to avoid Quick Response Code is by after two-shot chromatography, it is not easy scanning recognition because chromatography error is larger, preferably by entire two
It ties up code one-step print to complete, in other words, be completed entire Quick Response Code as one of color code block (8) one-step print.By Quick Response Code
Two (9) of neighbouring, additional field printing color lump (3) as the color code block of two-shot chromatography.
In order to reduce occupied space, saving the space of a whole page as shown in Figure 10 can also be by the field printing color lump (3) of additional
Two (9) of color code block as two-shot chromatography are arranged in the frame line near Quick Response Code.
After the additional chromatography of above-mentioned one-step print, be just combined into it is as shown in Figure 9, Figure 10 have 12 kinds on the spot
Color（It is not shown）Containing coding (2) printed article (1).
The printable fabrics such as studies have shown that paper, film are necessarily stretched and are loosened repeatedly in printing process, therefore inevitable
Generate unavoidable dilatation.Domestic and international most accurate printing machine at present, two-shot chromatography error is also all positive and negative
0.15mm or more.For example, necessarily leading to ghost image as shown in figure 12 after same group of coding (2) two-shot chromatography（I.e. two-shot chromatography misses
Ghost image caused by difference）.
Prepare a technical grade optic micro distance camera lens and digital camera, by the field printing color lump (3) in coding (2) into
Row bust shot, to obtain its photochrome；Then the photochrome of shooting acquirement, corresponding coding (2) information are stored together
