A kind of technical solution for the narrow slit method for anti-counterfeit that transfinites of the present invention is as follows.
One kind transfinites narrow slit method for anti-counterfeit, including printed codes (2) layer of ink or to stock (1) on stock (1)
Upper printed codes (2) and picture and text (3) layer of ink, which is characterized in that including：
1. encoding (2) or picture and text (3) layer of ink is equipped at least one narrow slit (4), narrow slit (4) width K≤0.05mm or 0.04mm
Or 0.03mm or 0.02mm or 0.01mm or 0.005mm or 0.001mm；
2. bust shot encodes the narrow slit (4) in (2) or picture and text (3) layer of ink, the gap characteristic information of narrow slit (4) is obtained with acquisition
(5)；Wherein, bust shot multiplying power n is can clearly record the gap characteristic information (5) of narrow slit (4) as established standards；Here institute
The gap characteristic information (5) stated includes the personal characteristics such as narrow slit (4) width, length, shape, curvature, direction, color, brightness letter
Breath；
3. combining coding (2) information as gap characteristic archives (8), storage to access mobile interchange gap characteristic information (5)
In the antifake examining system database (7) of net (6)；
4. anti-fake examination system receives（Consumer/user）The gap characteristic to be checked on stock (1) that shooting mobile phone (9) is sent
Information (5), and it is matched with gap characteristic archives (8), then will differentiate conclusion presentation of information in（Feed back to）It claps
According on mobile phone (9) screen.
It is appreciated that narrow slit (4) width K described in narrow slit to be checked (4) width K and gap characteristic archives (8) is carried out
Matching, if being consistent, will differentiate conclusion be genuine presentation of information in（Feed back to）On shooting mobile phone (9) screen；If not being consistent,
To then differentiate conclusion be false presentation of information in（Feed back to）On shooting mobile phone (9) screen.
It is preferable that further taking the one or more of following technical measures.
1. using ink-jet printer on stock (1) spray printing coding (4) or/and picture and text (5), and nozzle (10) with hold
At least one filament (11) is set between print object (1), the ink droplet (12) crossed to injection with filament (11) intercepts, thus
Some narrow slits (4) are formed in coding (2) or/and picture and text (3) layer of ink；Wherein, filament (11) width≤0.05mm or 0.04mm or
0.03mm or 0.02mm or 0.01mm or 0.005mm or 0.001mm.
Printed codes (4) or/and picture and text (5) are come to the nonwettable stock of ink liquid (1) or are selected to holding 2. selecting
Print object (1) nonwettable ink liquid comes printed codes (4) or/and picture and text (5), so that ink liquid and stock (1) connect
Contacting surface tends to reduce（Ink liquid is necessarily shunk when ink liquid surface tension is more than the adhesive force in printing face, this, which is called, does not soak
Moisten phenomenon）And generate crack --- narrow slit (4).《Baidupedia》Explanation about infiltration：One be placed on clean glass plate
Drip silver, can roll on a glass, without being attached to above.One block of clean sheet glass is immersed in mercury and is taken again
Out, also non-cohesive mercury on glass.This phenomenon is just called not infiltration phenomenon, and for glass, mercury is not immersion liquid,
For mercury, glass is not infiltrate solid.When with solid contact, along surface of solids extension, what is be attached to each other show liquid
As referred to as liquid infiltrates solid, referred to as infiltrates.If liquid, when with solid contact, contact surface tends to reduce and be not easy attached
It, then referred to as liquid does not infiltrate solid, does not infiltrate referred to as.It infiltration and does not infiltrate and is decided by liquid and solid property between the two
Matter.Same liquid can infiltrate certain solids, but differ and surely infiltrate other solids.For example, water energy Sized glass but cannot
Infiltrate paraffin；Mercury can infiltrate iron, copper, zinc and be unable to Sized glass.Creative, the present invention is not herein using soaking
Profit phenomenon generates the narrow slit that transfinites (4) that the width that existing printing machine can not print much is narrower than 0.06mm so that this hair
Bright product has not reproducible characteristic.
3. in encoding (4) or/and picture and text (5) position on stock (1), not infiltrating for curing ink liquid is printed in advance
Coating (15), then again will coding (4) or/and picture and text (5) be printed onto and do not infiltrate coating (15) above so that ink liquid with not
The contact surface of infiltration coating (15) tends to reduce and generate crack --- narrow slit (4).
4. be designed with original copy in the print original text of coding (2) or/and picture and text (3) stitches (14) in vain, and is encoded on stock (1)
(4) or/and diffusion coating (16) is gone up in picture and text (3) region, advance printing, and original copy is promoted to stitch (14) in vain after spray printing comes out
It is tied up and narrowed by surrounding ink diffusion, to form required narrow slit (4).
⑤（It is appreciated that in order to obtain the photo for meeting antifake examining system software specifications, consumer should be prompted）It will clap
It is placed on stock (1) 8-16 centimetres before narrow slit (4) of position according to mobile phone (9) camera lens, to good focal length, is shot to narrow slit (4)
An at least photo is simultaneously uploaded in antifake examining system database (7), to reduce rate of retaking, improves user experience.Research is also
Display：When camera lens is less than 8 centimetres at a distance from narrow slit (4) or higher than 12 centimetres, captured photo cannot be recorded clearly
The minutia of narrow slit (4), easily leading to antifake examining system software can not accurately identify.
6. gap characteristic information (5) to be checked is matched with gap characteristic archives (8), if measuring narrow slit to be checked (4)
End has 30 microns or less or 15 microns or less or 10 microns or less or 5 microns narrow slit (4) tips below, then will mirror
Other conclusion is genuine presentation of information on shooting mobile phone (9) screen；Conversely, will then differentiate that conclusion is false presentation of information in taking pictures
On mobile phone (9) screen.This technical measures has beneficial technical meaning very much, because dry tip is inevitable very narrow
It is narrow, and the print result of to be original copy stitch in vain (14) in the false crack of print reproduction output, it is impossible to so narrow, it is necessarily wider than print
Brush limit 0.06mm.
Also it is preferable that further taking the one or more of following technical measures.
1. can be by not infiltrating the method that diluent and filler are added in coating, described not infiltrating coating (15) to adjust
Adhesive force size.Researches show that：The ratio of the preferably described adhesive force and ink liquid cohesive force for not infiltrating coating (15)
≤ 0.95 or 0.90 or 0.85 or 0.80 or 0.75 or 0.70 or 0.65 or 0.60 or 0.50.It thus can be by changing its ratio
It is formed by fracture width to adjust, to produce the narrow slit (4) of length, ultra-narrow personalization can not replicate, random.
2. the coating that do not infiltrate not infiltrated in coating (15) is uneven distribution state.In other words, some blocks, which have, does not soak
Moisten coating, other blocks do not infiltrate coating.Such as the flakes distribution etc. when presentation video screen no signal.Such one
Come, so that it may which crack caused by making has very strong random character.
3. the diffusion coating in diffusion coating (16) is uneven distribution state.In other words, some blocks have diffusion coating,
Other blocks do not spread coating.Such as the snowflake screen shape distribution etc. when presentation TV no signal.So, so that it may make
Generated crack has very strong random character.
4. the original copy stitch in vain (14) be acute angle original copy stitch (14) in vain, ranging from 3 °~15 ° of acute angle or be 3 °~15 ° or
It is 3 °~25 °；After original copy stitches (14) spray printing into narrow slit (4) in vain, acute angle one end will make up because surrounding ink liquid is spread,
Then lead to that narrow slit (4) shortens or acute angle one end will be opened because surrounding ink liquid is shunk, then lead to narrow slit
(4) elongated；The length information of the narrow slit (4) is collected the anti-counterfeiting characteristic auxiliary file as stock (1)；If to be checked
The length of narrow slit (4) is not consistent with the record in anti-counterfeiting characteristic auxiliary file, then will differentiate that conclusion is false presentation of information in bat
According on mobile phone (9) screen；Conversely, if the length of narrow slit to be checked (4) is consistent with the record in anti-counterfeiting characteristic auxiliary file, will reflect
Other conclusion is genuine presentation of information on shooting mobile phone (9) screen.
5. forming the ink droplet (12) of the coding (4) or/and picture and text (5), density is 1.25 times of lateral density
More than, cracking initiation is between adjacent two file and consistent with page orientation (19).The captain for opening printing machine both knows about, stock
(1) printing when advance direction, commonly referred to as page orientation (19), file described here refer to page orientation (19) one
The direction of cause, horizontally-arranged refers to the direction vertical with page orientation (19).Here why requiring the file density of ink droplet (12) is
1.25 times or more of horizontally-arranged density, precisely in order to occur four scattered phenomenons after preventing ink droplet (12) from shrinking, in order to avoid longitudinal direction cannot be formed
Crack.
6. encoding some ink droplets (12) at narrow slit (4) edge in (4) or/and picture and text (3), being split at random by filament (11)
Semicircular ink valve (17), the location information of black valve (17) be collected the anti-counterfeiting characteristic auxiliary file as stock (1),
To differentiate the true and false of stock (1)；If in black valve (17) position at narrow slit (4) edge to be checked and anti-counterfeiting characteristic auxiliary file
Record is not consistent, then will differentiate that conclusion is false presentation of information on shooting mobile phone (9) screen；Conversely, narrow slit to be checked if (4) side
The black valve of some of edge (17) position is consistent with the record in anti-counterfeiting characteristic auxiliary file, then will differentiate that conclusion is genuine presentation of information
In on shooting mobile phone (9) screen.
7. a plurality of filament (11) is set as netted, or parallel lines are set as, or be set as cross spider, or be set as disorderly line segment.
8. filament (11) is constantly shaken, so that the position of its narrow slit (4) formed in coding (4) or/and picture and text (5) is not
Disconnected offset variation.
Ratio K/H≤0.7 of narrow slit 9. (4) width K and ink droplet (12) diameter H.
The reason of product of the present invention can not replicate (or saying the anti-fake principle of the present invention)：It is only following to replicate the method faked
Two kinds of possibility.
One is, printing house oneself (defalcating) production when repeat spray printing replicate narrow slit (4).This method replicates narrow
Stitching (4) must relative to the exact position described in the exact position of coding (4) or/and picture and text (3) and gap characteristic archives (8)
It is not consistent so, anti-fake examination system can necessarily identify.The those skilled in the art for being familiar with printing knowledge should be understood that printing machine
National standard chromatography error >=± 0.2mm.And the present invention describes the accurate of narrow slit (4) using the method acquisition of bust shot
Position (describes its microscopic features), records accuracy (i.e. resolution ratio) and has reached 0.001mm, the two difference exceedes hundred times.By
This error influences, and when the manufacturing, anyone (including printing house oneself) is all difficult to the exact position that spray printing goes out multiple narrow slits (4)
(microexamination is carried out using the resolution ratio of 0.001mm) identical stock (1).Moreover the present invention additionally uses constantly
Filament (11) is shaken, so that the position of its narrow slit (4) formed in coding (4) or/and picture and text (3) is with very strong random
Property.
The second is, fake producer's high definition scan the image of coding (4) or/and picture and text (3), then go spray printing replicate narrow slit (4).
The edge for the narrow slit (4) that this method replicates can necessarily differentiate necessarily without semicircular black valve (17), antifake examining system
Out.The those skilled in the art for being familiar with ink jet printing knowledge should be understood that the commercial ink-jet on current domestic and international market prints
Machine, can the ink dot (12) that comes out of spray printing and original copy stitch the minimum widith of (14) in vain as 0.06mm.It is limited, is faked by appointed condition
Person can not copy the size semicircular black valve (17) many less than 0.06mm and original copy stitches (14) in vain.It can be seen that in advance
Upper original copy is designed in coding (2) or/and picture and text (3) electronics original text and stitches (14) in vain, its spray printing is out formed（It is false）Narrow slit (4)
Width K be naturally larger than 0.06mm, will not more be less than 0.03mm.
A kind of technical solution of anti-fake product of the present invention is as follows.
One kind transfinites narrow slit anti-fake product, including the coding (2) that is printed on stock (1) or is printed on stock
(1) coding (2) on and picture and text (3), which is characterized in that including：
1. on coding (2) or picture and text (3), there is at least one narrow slit (4), narrow slit (4) width K≤0.05mm or 0.04mm
Or 0.03mm or 0.02mm or 0.01mm or 0.005mm or 0.001mm；
2. gap characteristic information (5) is used as gap characteristic archives (8) after combining coding (2) information, it is stored in access mobile interchange
In the antifake examining system database (7) of net (6)；
3. anti-fake examination system receives（Consumer/user）The gap characteristic to be checked on stock (1) that shooting mobile phone (9) is sent
Information (5), and it is matched with gap characteristic archives (8), it then will differentiate that conclusion presentation of information is shielded in shooting mobile phone (9)
On curtain.
It is appreciated that encoding (4) or picture and text (5) position on stock (1), be printed with ink liquid does not infiltrate painting
Layer (15), encodes (4) or picture and text (5) are printed on and do not infiltrate on coating (15).
It is preferable that it is local coatings not infiltrate coating (15), encodes (4) or picture and text (5) are printed on stock (1)
Part do not infiltrate on coating (15).
It is appreciated that in the coding (4) or/and picture and text (5), the position of narrow slit (4) has randomness.
Also it is appreciated that ratio K/H≤0.7 of narrow slit (4) width K and ink droplet (12) diameter H.
Also it is appreciated that narrow slit (4) end has 30 microns or less or 15 microns or less or 10 microns or less or 5
Micron narrow slit (4) tip below.
Also it is appreciated that the coating that do not infiltrate not infiltrated in coating (15) is uneven distribution state.
Fake producer copies narrow slit (4) using the method spray printing for reserving some gaps on printing original text in advance in order to prevent, this
The ultra-fine filament (11) more than printing Limit Width has been selected in invention, so that the ink droplet (12) that ultra-fine filament (11) crosses injection
It is stopped, to form some ultra-narrow narrow slits (4) in coding (2) or/and picture and text (3).The present invention also takes ink
Liquid, which is printed onto, not to be infiltrated coating (15) etc. and does not infiltrate innovative solution on solid, is dexterously formed some ultra-narrow and is split
Seam --- narrow slit (4).Researches show that：When the width K≤0.03 of the ultra-narrow narrow slit (4), prints imitated fraud, almost just can not
It can.
Coding (2) of the present invention, refers to various codings, for example, sequence number, bar code, Quick Response Code, the date of manufacture,
False proof code, anti-channel conflict coding, commodity are traced to the source code, it is preferable to have uniqueness, randomness, include query link network address
, non-encrypted Quick Response Code.
Shooting mobile phone (9) of the present invention is also known as smart mobile phone.
Gap characteristic information (5) of the present invention includes feature photo.
Compared with the prior art " transfinite method for anti-counterfeit and product (CN106096970B) ", the present invention can generate to be had as follows
Beneficial effect.
Short flannel printing element is omitted in one, and one short flannel printing element of restructuring is removed for hundreds thousand of yuans without input,
The shortcomings that overcoming fast low, the easily stifled version of existing short flannel printing element print, easily leading to production line stop.
Secondly, it is simple and practicable, need to only put in front of the nozzle (10) and set one or more filament (11)；Alternatively, by oily
Black liquid body, which is printed onto, not to be infiltrated coating (15) etc. and does not infiltrate on printing face.In other words, present invention omits short flannel printing is single
Member simplifies production, and scrap build expense is almost nil, will not interfere normal print production.
Thirdly, ultra-narrow narrow slit (4) width K be much narrower than the diameter H of an ink droplet (12), and its exact position is random
, it fakes to be difficult to print reproduction.
As stated in the background art, " even using existing most accurate commercial offset printing machine on the market, can not also print
Go out the point/line that transfinites that width is narrower than 0.06mm ", similarly, even use existing most accurate commercial offset printing machine on the market,
Also (i.e. reserved) can not be printed and go out the ultra-narrow narrow slit (4) that width is narrower than 0.06mm.
The present invention looks for another way, the method that the ink droplet (12) crossed to injection using ultra-fine filament (11) is stopped,
Ultra-narrow narrow slit (4) is formd in coding (2) or/and picture and text (3).It also takes ink liquid being printed onto and does not infiltrate coating (15)
Deng the method not infiltrated on solid, also take method ink liquid being printed onto on diffusion coating (16), in coding (2)
Or/and form ultra-narrow crack in picture and text (3) --- narrow slit (4).
Four, application of the invention, will improve the anti-fake of " transfinite method for anti-counterfeit and product (CN106096970B) " and answer
