Background technology

(1) counterfeit money and print principle thereof

1, the characteristics of current counterfeit money crime

The counterfeit money crime resembles one strand sewage and mixes in the economic globalization trend and spread unchecked everywhere.Introduce according to " Renminbi real and fake discrimination training manual ": from the counterfeit money of taking over, be machine-processed offset printing counterfeit money more than 95%, wherein, big counterfeit money is in the great majority; Adopt electronic scanning plate-making, offset lithography, four-colour chromatography person to account for the overwhelming majority; Adopt photomechanical production, lithography person quantity few, the minority intaglio printing is also arranged; Use computerized print, duplicating person's quantity seldom.From network the counterfeit money intelligence analysis of Sou Jiing as can be known, the east counterfeit money is printed as many with routine, the west counterfeit money is many with desktop printing (office equipment) and digital color printing.As the highest counterfeit money of discovering and seizing in Guanlan, Shenzhen in June, 2004 of domestic fidelity, adopt red blue color fibre paper first and make with offset lithography; Domestic made counterfeit money is offset lithography basically in Guangdong, and tool used in crime mainly is single, double look offset press; People's Bank of China's net " principal character that " the super K of calendar year 2001 version " is false dollar " is introduced: this counterfeit money adopts intaglio plate to print, " ... two the same thicknesses of lines about the lamppost of the back side ... the same length of back side clock tower hour hands ... " this illustrates that this counterfeit money adopts electronic scanning, the computer colour-separation drafting, intaglio printing; The domestic made counterfeit US note of Russia is made as many with intaglio process.According to media report, the present counterfeit money in U.S.'s circulation, from overseas account for 60%, adopt offset lithography mostly, denomination is many with 100 yuan of certificates; Domestic made counterfeit money denomination is 20 yuan of certificates mostly, mainly adopts digital technology to print, and wherein adopts the color copy machine counterfeiter to account for 30%.200 dollars of certificates of Bush's head portrait " new edition banknote " that U.S. Luo Nuo carat pieze city in 2003 finds first are to use the computing machine planar design, the counterfeit money that digital technology is made.From the counterfeit money information that each various medium is collected, lawless person's tool used in crime all is international, civilian chromatic printing equipment.

Have machine-readable password on the genuine note magnetic security line, belong to state secret, be used for automatic teller machine or automatic currency counting and detecting machine.Various on the market conventional cash inspecting machines are because this password right to use of tool not can only detect having or not of banknote fluorescence reaction and magnetic ink, and are unable to do what one wishes naturally in face of the counterfeit money of forging under the current modern science and technology condition, fall into enemy hands when closing.Some criminal gang is illegal to decode and the machine-readable password of use banknote, by forging technical parameters such as genuine note watermark, fluorescence, safety line, also may cheat some automatic currency counting and detecting machine and automatic teller machine.CCTV.COM CCTV.com reported to be entitled as " the mad counterfeit money of washing of offender's automatic teller machine " on July 22nd, 2004: " Ministry of Public Security reveals that recently all par value cash of circulation all have counterfeit money to find on the market at present.Significant be, the nearly stage several the behaviors that utilize the automatic teller machine crime occurred in a plurality of provinces and cities ... it is introduced, there is special criminal gang to aim at the automatic teller machine of bank at present, technical parameters such as their watermark by forging banknote, safety line, thereby reach the parameter index of some automatic cash dispenser approvals, counterfeit money will deposit machine in as genuine note like this, and money has also been thrown offender's bank account into ... ".This type of case all has report both at home and abroad.

In peacetime, that utilize high-tech manufacturing counterfeit money all is reactionary gang's tissue, criminal gang or lawless person, and they are purpose to make profit specially.This class counterfeit money is called " people's forge money ".Be characterized in making profit to as if vast general public, adopt civilian chromatic printing equipment crime.In a single day counterfeit money circulates, and lawless person's purpose reaches, and remaining thing is to shift the blame mutually between the numerous common people, and this closes to have arrived bank, has been the final tache of counterfeit money circulation, irrelevant with the lawless person already.Therefore, first link (being the very first time, first place, first receiptor) that circulates of counterfeit money is to intercept counterfeit money first critical point.At this, first receiptor only can't discern with " two touching three tins at a glance " often, and shortage is suitable for banknote tester and receives counterfeit money by mistake again.

Crucial problem is how to allow every common people all recognize counterfeit money, and each link that reaches after this when counterfeit money circulates is tackled it.If handy banknote tester is arranged, whom has be also ready to receive other counterfeit money? if everybody recognizes counterfeit money, also has counterfeit money all over the world?

It will be argued that the printing principle of having only by the research counterfeit money, just can find the Achilles' heel of counterfeit money.Inspired by biological DNA parent-offspring's authentication technique, I study true and false coin gene separately from modern colored printing technical know-how angle, seek essential distinction and discrimination method between them, thereby establish the innovation theory that banknote is differentiated, and cause a series of technological innovations.Micro-currency examine technology that Here it is, it also is micro-Jianzhen's technology is differentiated the field at banknote application.

2, the print principle of counterfeit money

The basic theory of modern colored printing technology is a graphic arts chromatology, and how its research goes up batch duplicating (i.e. printing) colored original at physical supports such as paper (being stock).Only need in theory to mix with proper proportion with blue or green (C), pinkish red (M), yellow (Y) three kinds of colorants (printing ink, ink or carbon dust), can reappear various colors in the original copy, this CMY is called the colorant three primary colors; (being printing technology) adds tusche in addition to obtain just black (K) in the practice, so become printing four primary colours, also claims (CMYK) four primary colours chromatographys; Simultaneously original image is decomposed into four primary colours sites (through the pixel of color separation), each primary colours site is arranged by certain rule (amplitude modulation or frequency modulation), with the implementation space colour mixture, this operation claims screening color separations.In other words, have only colored original is decomposed into countless sites, could realize colored printing through four primary colours chromatographys.So " site picture group, four primary colours chromatographys " are the ultimate principles of modern colored printing technology.

Based on this principle, produced offset lithography, gravure, flexo, the industrial conventional printing equipment of biting and so on, also produced the industrial digital printing equipment of Computer To Plate, digital color printing and so on, and computer (ink-jet and laser) is printed, color photocopying and so on office desktop publishing system.They just realize technology, purposes and the scientific-technical progress degree difference of colored printing, there is no differentiation in essence.These equipment all are international chromatic printing equipments, belong to civilian chromatic printing equipment.

Colored original is carried out the branch that method that screening handles has am screening and fm screening.The feature of amplitude modulation net is: " with the primary colours site by arranged, and the site size is with the pixel tonal variation, and the netting twine of different base colors staggers at a certain angle ", and bigger corresponding to the pixel site of original copy tone dark.The printability of amplitude modulation net and stability are all better, are convenient to realize computer color management, therefore, and widespread usage all in offset printing, gravure and digital printing.Its shortcoming is to locate duplicating the dark color of colored original (as fine and closely woven patterns such as the hair of the up name of banknote, interarea volume or portrait, group's flowers), piles up that to cause its look dense even fuzzy because the site is big; Light color fine rule (as banknote enamel shading, portrait face light) is located, and little dot loss takes place, and to cause its look light even leak white; Color lump edge indentation.

The feature of modulating net is: " the tiny stochastic distribution shape that is in each primary colours site, site point apart from the pixel tonal variation, no netting twine ".Corresponding to the darker pixel site comparatively dense of original copy tone.The site of modulating net is tiny, is suitable for reproducing the details of colored original, but at high light place, equally also little dot loss can take place.In addition, because it requires very harshness to printing conditions such as equipment, thereby the in fact also prematurity of this technology is not all applied in the industrial conventional printing equipment of offset lithography or intaglio printing and so on.

Offset printing belongs to lithography.Be the PS version or directly make the PS version through copy by the film of laser photocomposing machine output, enter printing process then by computing machine.There is the special messenger to pick the film in the counterfeit money case of Guanlan, Shenzhen, illustrates that this counterfeit money adopts offset printing.This counterfeit money was stamped in the ink transfer on the PS version on the paper by blanket in when printing, the site big sharpness that reduces that rises can occur, and its printed matter feel is level and smooth, and the picture and text micro-image has the feature of distinctness " site picture group, four-colour chromatography, amplitude modulation net ".The alignment precision of offset printing is subjected to factor restrictions such as mechanical precision, forme cover accuracy, operant level, paper parameter, ambient temperature and humidity and rating of machine (monochrome, double-colored, four looks or polychrome).Four looks above printing machine alignment precision is higher, and the palpus of single, double look printing is by look plate change, alignment extreme difference.According to the media report analysis, domestic most of counterfeit money is printed with single, double look printing machine, and the double-colored color press of homemade 08 type is its mainstream model, and this counterfeit money picture and text are enameled the wiring dislocation clearly, and pros and cons is more at random to the impression case.

What intaglio printing was used is intaglio plate, and its alignment precision is the same with offset printing, and to be limited by mechanical precision, rating of machine (chromatic number) etc. all multifactor.Modern gravure adopts the laser engraving or the electromagnetism engrave of electronic scanning, computer colour-separation drafting, computer control.Printing ink during printing in the forme ink cell is glued by paper and forms the stereo structure ink marks, and can not rise greatly in its site, so sharpness is better than offset printing; Locate corresponding to original copy dark color (as row name, braille etc.), its site diameter is big, ink cell is dark, ink marks is thicker, this ink marks protrudes paper so feel is rough, and the coloured picture of gravure or false Renminbi all have the obvious characteristic of " site picture group, four-colour chromatography, amplitude modulation net "." super K false dollar " may adopt this technology to forge, and may adopt net (being that the site links to each other) engrave on the spot, and its micro-image is still had a site form.The tradition gravure adopts photo colour separation, and chemical etching plate-making has screening and two kinds of formats of screening not.Print the palpus screening chromatography of the coloured picture (as false Renminbi) of transferring (rich color, gradation of hue) continuously, its ink marks has tangible lattice point structure feature; Print not screening Plate making printing of discontinuous accent coloured picture (color is single-minded, as false dollar of old edition).Screening plate-making gravure, its picture and text micro-image still has the lattice point structure feature.With (old edition dollar etc. are look banknote class specially) counterfeit money that the plate-making of screening not gravure is forged, point, line, color lump on the picture and text, its face profile can be similar to genuine note, original copy tone depths ink marks is thicker, but " face " form on ink marks top layer is uncontrollable, as the stone riprap beach or as ridge, and no site form.This counterfeit money does not have the disease of covering of amplitude modulation net, and sharpness is the highest, and harmfulness, duplicity maximum differentiate that difficulty is also maximum.Magnifier is useless at all to it.Will be as seen on its micro-image, the ink marks of counterfeit money is obviously thicker than genuine note, and is different fully with the ink marks three-dimensional configuration of the corresponding sampled point of known genuine note.Be envisioned as injection mold if genuine note gravure ink marks is envisioned as embossed portrait, the gravure of certain injection moulding, be not difficult to infer, how is this chemical etching used for making injection mold? the embossed portrait made from the mould of this chemical etching, at most be profile similarity and be stereo structure, and changed beyond recognition certainly! Its ugly features (being the three-dimensional configuration of its ink marks) must be completely exposed on micro-image.That is, counterfeit money must be different fully corresponding to the micro-image of the same sampled point picture and text of known genuine note.

Since 2003, new edition begins to change into the colored picture and text space of a whole page for 20 dollars.Before this, like solemnity, steady old edition dollar to habitually practise double-colored printing.It is not owing to there is the false proof design of colored shading, so there is not the difficulty of multicolor overprint, if lawless person's autogamy spot ink, adopt not photo etching, the intaglio printing of screening, its counterfeit money feel is rough, the picture and text effect may be very true to nature, and human eye and magnifier can't be distinguished at all.But will be as seen on micro banknote tester, its ink marks is thicker than genuine note, twitches more violent (seeing below), and " face " on top layer is changed beyond recognition.

Modern science and technology has also expedited the emergence of industrial typography of new class and equipment, i.e. digital printing equipment (digital color printing), and correlation technique also has the Computer To Plate system, digital sample printing machine etc.Because amplitude modulation net printability, stability are all fine, be convenient to realize the computer color management again, so this known class printing equipment is still continued to use the am screening technology.This type of printed matter picture and text ink marks does not protrude paper, and feel is level and smooth, and its micro-image has amplitude modulation net feature, and chromatography precision is very high.This kind equipment need not can adjust the quality of printed matter in the printing at any time through plate-making, even revises graph-text content, and chromatography precision is more much better than conventional printing, and the print cycle is very short, and can realize networked long-range printing, is one of following printing technology developing direction.The colored wiring nature of counterfeit money that this kind equipment prints, color fidelity is higher.The lawless person who sees western developed countries such as the U.S. on the medium commits a crime with it more, does not see the domestic report that this precedent is arranged.For example, www.chinanews.com once reported " ... American side is introduced, and only the whole world in 2002 has just produced about 4,400 ten thousand false dollars, wherein 40% elaboration counterfeit money for adopting digitizing technique to forge ".

Computer printer (as ink-jet printer, laser printer), color copy machine etc. have formed another kind of office digital printing equipment---desktop publishing system.They use blue, red, yellow, black (correctly say and should be: blue or green, pinkish red, yellow, black be CMYK four primary colours) ink or carbon dust.All indicate an important techniques index---resolution on the packing case of this kind equipment and the instructions.As: " ultimate resolution: 2400dpi ", it shows can make a call to 2400 sites per square inch.The high more coloured picture details of printing of this resolution is clear more.As seen, this class printing equipment is used " site picture group, four-colour chromatography " this ultimate principle equally.Its micro-image visible " the tiny stochastic distribution shape that is in site, no netting twine " belongs to modulating net.Ink or the carbon dust pollution paper that flashes takes place in this kind equipment inevitably when printing, cause the blank space of corresponding colored original also to have " site ", make image detail smudgy, but its alignment precision is also higher.This kind equipment need not plate-making, and on office, family, the car, the field all can work, the print cycle is ultrashort, and output is the amount doesn't matter, is one of important tool used in crime of counterfeit money printing.Counterfeit money that this kind equipment prints is shoddy goods all.May set foot in the counterfeit money crime in order to monitor color copy machine, a resolution is passed through in the tenth the anti-counterfeit money meeting of International Police Organization: all member states should provide the relevant information that adopts " tracker " that color copy machine is followed the tracks of to International Police Organization.Do not see the report that has domestic employing color copy machine to print counterfeit money on the medium.

Civilian chromatic printing equipment is used to duplicate the commercial printing of colored original or is used for office.International for realizing, they all must meet each correlation technique standard in the colored printing technology international standard system.Industrial conventional printing equipment class such as civilian chromatic printing equipment includes offset printing, gravure, flexo, protruding seal, bite; Industrial digital printing equipment class such as digital color printing, digital sample printing are arranged; Office desktop publishing system classes such as computerized print, color photocopying are arranged.They just realize technology difference, the scientific-technical progress degree difference of colored printing, or the purposes difference, and their print principle all is " site picture group, a four-colour chromatography ", there is no differentiation in essence.Specifically, these are international, the printed coloured image of various (civilian) chromatic printing equipment all has the essential characteristic of " site picture group, four-colour chromatography ", and this is called " lattice point structure " feature.Print counterfeit money with these civilian chromatic printing equipments and do not have what difference with printing common color picture.

The international standard of browsing printing-ink all contains filler as can be known in the various ink formulations.

3, " gene " of counterfeit money

Chromatic printing equipment is used and civilian branch by right to use existence official.The official is used for banknote, stamp, security, passport and government secret file etc. with printing equipment, by the purposes difference classification is arranged respectively again, such as, money press is special, special-purpose printing machine, and is also different with the machine of seal stamp." People's Republic of China's Renminbi management rules " the 12nd regulation: material particulars such as the special material of printing Renminbi, technology, technology, specialized equipment belong to state secret; Article 13, regulation: without People's Bank of China's approval, any entity or individual must not develop, copy, introduce, sell, buy and use the peculiar anti-fake material of printing Renminbi, anti-counterfeiting technology, false proof process and specialized equipment.At time of peace, government carries out strong secret control for the correlation technique of printing of bank note, material, equipment etc., and effectively supervision is implemented in some adjacent field.As government some speciality paper, printing ink, gravure machinery are implemented supervision.

The lawless person is limited by disguise, ageing, practicality can only adopt civilian chromatic printing equipment crime.What be suitable for printing counterfeit money has an industrial conventional printing equipment of offset printing, intaglio printing press and so on; The industrial digital printing equipment of digital sample printing, digital color printing and so on is arranged; Computerized print, color copy machine and so on office desktop publishing system is arranged.The false Renminbi that all these civilian printing equipments are printed and such as Euro, colored banknote (seeing below) the new edition dollar, identical with the character of printed color picture, all have " site picture group, four-colour chromatography " i.e. feature of " lattice point structure ".It is as bion " gene ", congenital intrinsic, can't evade.

Therefore, the false Renminbi that adopts any civilian chromatic printing equipment to print all has the feature of " lattice point structure ".

Obviously, the government of any country and bank of issue, all can not adopt any civilian chromatic printing equipment is own printing of bank note.In other words, the banknote of any country distribution does not have the feature of " lattice point structure ".On the contrary, all banknotes that " lattice point structure " feature is arranged, no matter the currency that it is issued as which country or area, no matter it by whom, when, the place, printed with what equipment,, all be counterfeit money also no matter it has or not fluorescence, watermark, safety line or other anti-counterfeiting characteristic, how true to nature!

4, the super counterfeit money problem of following version

Counterfeit money always is accompanied with genuine note, grows with each passing hour with science and technology.Browse the up-to-date scientific and technological achievement of print field, perhaps may predict image and lawless person's trend of following version counterfeit money.

The up-to-date release of Japanese in recent years screen company " look and must reach FMAM mixing screening technology " may make the counterfeit money offender overjoyed.Look must to reach site diameter minimum be 10.5 microns, a bigger site is formed in the little site that number does not wait, and the production process of the 2400dpi/175lpi that only need follow conventional lines and equipment just can realize that the high line of 300lpi counts the printing quality of site.Personage's hair and meticulous group lines such as spend will no longer break or be to pile up shape.The counterfeit money of printing with its will be than am screening more true to nature, not only human eye can't be discerned, the common magnifier of also can out-tricking fully.Yet, owing to its image can only be made up of the site, four primary colours chromatographys, therefore this counterfeit money micro-image will have " site picture group; The lines flow smoothly, fine rule continuous, the edge is serrulate, fine and closely woven clear patterns; Four primary colours chromatographys, the interior visible tiny color point distribution of colored lines is scattered related colour China ink site in the color lump, and site size, some distance are all with the pixel tonal variation; No netting twine " characteristics.Because of the improvement that is mask-making technology of this screening new technology, and the essence of its site picture group four-colour chromatography there is no change, so the feature of tool " lattice point structure " still.

With look is one of basic demand of colored printing technology, for pursuing color fidelity, by the computer color management, can realize increasing some special look versions when electricity divides plate-making on the CMYK basis, to replenish the deficiency of CMYK color space colour gamut.In private small-print factory, the talent that can use this technology is less, most operative employee by rule of thumb, " gambling wink " and for it.

Standard high-fidelity six color inks that logical (pantone) company of U.S. Pan releases recent years are to increase bright orange and pure green two kinds of look China inks on the CMYK basis.It has enlarged colour gamut simultaneously having improved the printing ink color developing, especially can directly realize color management by computer software, be desirable high-fidelity color printing with China ink.With Asians's image that it is printed, blee is with red no longer partially or inclined to one side Huang.Print if be used for counterfeit money, will make its color more true to nature.Because these printing ink six look chromatographys are the improvement of four primary colours chromatographys, also do not change its essence, so the counterfeit money micro-image of its printing will possess the feature of lattice point structure.

If, the lawless person " looks and must reach " FMAM with logical (Pantone) standard high-fidelity six color inks of U.S. Pan and Japanese screen and mixes screening technology and add (Guanlan, Shenzhen counterfeit money is the sort of) red blue fibre paper, adopt gravure printing technique, be used for false Renminbi and print, the sort of counterfeit money is only real super counterfeit money.The picture and text color of the sort of counterfeit money and genuine note much at one, paper may not have fluorescence reaction, the reflective color of fluorescent ink can be as good as with genuine note, some relies on the discriminating instrument of spectral analysis may discern error; If the lawless person can utilize the illegal machine-readable password of decoding and using genuine note of modem technology, by " forge the technical parameters such as watermark, safety line of banknote; thus reach the parameter index of some automatic cash dispensers approvals, counterfeit money will deposit machine in as genuine note like this ".Predict this counterfeit money picture and text: finding of naked eye portrait hair is clear, facial color nature, and it is murky to feel expression slightly, state's note of the ancient Chinese clear patterns, stealthy denomination seemingly has like not having, and color shifting ink can variable color; Hand is touched the row name, braille has obvious Prwsnt, and other position feels of picture and text are rough, and paper texture truly has difference, shake cacophonia high up in the air; Under common magnifier, colored wiring Non Apparent Abnormality, the lines flow smoothly for colored shading, the continuous free of discontinuities of fine rule, the picture and text details is all identical with known genuine note, does not see the weak point of false dollar of super K the sort of " ... two the same thicknesses of lines about the lamppost of the back side ... the same length of back side clock tower hour hands "

If the lawless person uses photo etching, not screening plate-making, gravure, forgery such as old edition dollar the sort of (need not multicolor overprint) is the false foreign currency of look banknote class specially, is what kind of counterfeit money that again? imagination backcountry, poverty-stricken area and the relatively poor general public of culture background, in the face of this (suspicious) banknote, how to differentiate?

(2) the banknote graphic anti-counterfeiting function that is not exploited

The inventor has found the banknote graphic anti-counterfeiting function that is not exploited through research for many years.

Except the antiforge function of active services such as on record banknote fluorescence, watermark, safety line all fronts, the banknote designer has preset powerful antiforge function at the weakness of various civilian chromatic printing equipments on the banknote picture and text, summarize and get up to have " guiding principle four lines ".Be guiding principle promptly, be provided with " engraving gravure, colored shading, special ink, fine and closely woven pattern " four lines of defense with " strain line picture group ".Can have a taste of its exquisite antifalse effect by the banknote micro-image.Before this, this antiforge function is not effectively developed.

1, strain line picture group

The genuine note picture and text are made up of various lines, point, are called " strain line picture group ", are also referred to as " linear ".Genuine note is as the design of guiding principle through each local pattern of banknote picture and text; Counterfeit money all is made up of the site with various common color pictures are the same, and promptly " site picture group " is also referred to as " lattice point structure ".This is the essential difference between true, the counterfeit money picture and text.Difference is extremely distinct between the two, does not have equivocal part.

2, engraving gravure

Machine intaglio ink (abbreviation machine carving gravure) and hand engraving intaglio printing (being called for short hand carving gravure) are collectively referred to as the engraving gravure.Before this, people are accustomed to using the method for " two touching three tin of four survey at a glance " to differentiate the true and false of banknote).This is because genuine note has adopted the false proof design of engraving gravure, its ink marks protrudes paper so feel is rough, the counterfeit money that offset printing, computerized print, color photocopying, digital color printing etc. are forged, its ink marks does not protrude paper so feel is level and smooth, but if meet " false dollar of super K " and so on gravure counterfeit money, its ink marks also protrudes paper then must be taken in.The engraving gravure comprises machine engraving and hand engraving, and its elite is manual engraving technology.It requires the sculptor to possess fabulous art designing's overall qualities and consummate miniature technology.Wherein, hand is carved the gravure microfilm of characters, and the strong time of microscopic carvings calligraphy also must be arranged.Different sculptors all have distinct artistic individuality, if make them carve the works of same picture and text, its version is inevitable different; Same sculptor is if repeat the engraving of same picture and text works, and the front and back version also is not the same.Because the color lump of hand engraving, lines are three-dimensional, except that form parameters such as length, width, radian, turning, also have many identifiable three-dimensional configurations such as thickness, the hollow out depth, concavo-convex degree, side slope gradient, edge smoothness.The works of manual engraving promptly have the antiforge function of version uniqueness once affirmation, and the engraving gravure also just has the characteristic that can not clone simultaneously.The lawless person adopts any technological means to forge also can't clone it.

For the special look counterfeit money of (need not multicolor overprint) old edition dollar that adopts that not screening chemical etching, gravure forge and so on, may there be the site, under magnifier, its ink marks and strain line architectural feature are as good as.If the gravure ink marks is envisioned as certain injection moulding embossed portrait, gravure is envisioned as injection mold, and well-knownly is, any mould is not can make with chemical etching.Can only imitate its face profile and be stereo structure with the made embossment portrait of this mould, can't chisel and carve out the three-dimensional configuration of portrait face look, and its micro-image can be completely exposed these ugly features.That is to say that counterfeit money is not the same corresponding to the micro-image of known genuine note at corresponding sampled point picture and text.The antiforge function of engraving gravure uniqueness obtains universally acknowledged already, national governments all with it as the false proof unique skill of banknote, value warrant and certificate and use till today.

The portrait eye is one of sensitive part of micro-currency examine on the banknote picture and text.What be worth our pride is, the great man on the 5th cover Renminbi similarly is the most beautiful in world's banknote, and he wins on " manner ".Outstanding engraving great master Su Xihua carves great man's picture, and each details is all just right.As eyeball reflective spot hollow out place, big little by little then sight is like severeer, and it is dark right that a little bit smaller point then shows slightly, partially little by little a bit cold and detached, in high spirit, kindly and self-confident when just right.On micro banknote tester, the genuine note micro-image of having got used to, familiar just as household's face, any trickle difference all can cause our vigilance, Here it is the peculiar version uniqueness antifalse effect of hand carving gravure.This antiforge function is not that hand is touched or magnifier can utilize, and has only the micro-currency examine technology could ultimate attainment performance.

The engraving gravure is equipped with special ink again, and the micro-image of its ink marks such as jade embossment are rich in stereoscopic sensation, and ink marks meets that light one side is reflective, and one side backlight has shade, can present shade and change when changing the light source projects position angle; On micro banknote tester, when starting jumping lamp source function, what we saw is the ink marks top layer of engraving gravure, occurs along the phenomenon of two light source direction twitch, and this is called " the twitch effect " of gravure ink marks.The twitch that ink marks is thicker is more violent, as the background in Tian An-men in row name, main scape, braille, interarea volume, stealthy denomination, the national emblem; And a little less than the twitch that ink marks such as group's flower is thin around the facial light of the portrait place, stealthy denomination.Can judge ink marks thickness in view of the above.What twitch in the genuine note micro-image is strain line, and what the gravure counterfeit money was twitched is the site, and the counterfeit money site of flat stamping (containing offset printing, color photocopying, digital color printing) can not twitched.Modern engraving gravure is widely used in banknote master scape, row name, interarea volume, braille, microfilm of characters, places such as group's flower, and can realize highly difficult printings such as various colored wiring and color change easily.It is the position of difficult forgery of counterfeit money that portrait eye on the banknote, national emblem, microfilm of characters, row name, interarea volume, national writing, group spend, braille etc. located, and also is one of sensitive part of micro-currency examine.

False Renminbi can only adopt the site picture group, four primary colours chromatographys.The false Renminbi of the sort of employing intaglio printing, its micro-image can not expose the feature of lattice point structure with evading.This counterfeit money feel is rough; But on micro banknote tester, be the site of twitching everywhere with visible whole banknote.If add on the spot the net back with the false new edition dollar of chemical etching or electronic engraving gravure, Euro etc. the various foreign currencies of colored banknote class also be like this.From counterfeit money print principle angle, Renminbi and Euro, new edition dollar and so on " colored banknote " can't forge with screening mask-making technology not.

Therefore, the engraving gravure is the most reliable first defence line on the banknote picture and text, also is the most reliable foundation of micro-currency examine technology.

3, colored shading

Domestic and international various banknote is if can be divided into colored banknote and special look banknote two classes by the nominal value color.The false proof design of the former chromatic colour shading, as Renminbi, New Taiwan Dollar, Hongkong dollar, Euro, new edition dollar etc., it accounts for the overwhelming majority of various countries' banknote version; The latter does not have the false proof design of colored shading, as the old edition dollar.From counterfeit money printing technology angle, the former belongs to colored original, and the latter belongs to special chromogen original text.Color in riotous profusion on the banknote is made up of thousands of colored shading.It has lines, color lump and three kinds of shapes of color dot, have right and wrong, parallel, intersect, volume flower, concentric various combinations, plano-convex, average, plano-concave, concavo-concave various wiring are arranged, transition, gradual change, the various color change of rainbow are arranged.The color change place promptly is the place that colored wiring is concentrated on the banknote.Colored shading makes banknote become colored banknote, and she forces the fake producer must use site picture group, four-colour chromatography, thereby exposes the feature of its lattice point structure; She can also effectively destroy counterfeit money with look, makes the counterfeit money color distortion and is easy to recognize (i.e. one of object of " at a glance ... ").Genuine note is original printed matter, does not exist with the look problem, deliberately adopts many (tens even tens kind) specially look chromatography, and the big more options of its used ink colors depart from the Essential colour and the various special look commonly used of printing-ink; Counterfeit money is a duplicate, in order to pursue color fidelity, can only adopt site picture group, four primary colours chromatographys to copy, and relies on that color dot is spacing color mixed to be asked color emulation and have no other way.The counterfeit money of high fidelity may adopt four primary colours printing ink to add some spot ink chromatographys in addition, to improve color fidelity.This counterfeit money human eye is not easy to identify, under magnifier, can see its hachure such as dotted line shape, color lump edge indentation, wherein, the counterfeit money register trouble of offset printing or gravure, colored wiring dislocation.Under micro banknote tester, " Renminbi genuine note picture and text background is made up of shading, and lines are well-balanced smooth and easy, and colored wiring or doubling be nature accurately; The color lump intrinsic color is even; Color dot is arranged, and size is constant, color-grading; Ink marks is bright in luster beautiful, texture such as dyestuff.The colored shading of counterfeit money entirely by the site form, four primary colours (high fidelity person adds special look in addition) printing ink chromatography; Register trouble, colored wiring or doubling dislocation are common faults; The ink marks color is turbid dark, texture such as coating ".Present very strong visual contrast between the true and false coin picture and text micro-image, there is no ambiguous intermediateness between the two, very easily identification.

Lucuriant in design and color change part also is one of sensitive part of micro-currency examine on the banknote.The positive main scape shading of 20 yuan of certificates of 94 years versions of Hongkong dollar adopts the color dot matrix design of color-grading; The colored shading of the 5th cover Renminbi is the most complicated, wherein adopted the rainbow design, the colored wavy fine rule of visible many differences is concentric arrangement on micro-image, and other many colored lines setoffs are arranged, and counterfeit money is very easily lost the site and to produce look light or leak white at this.Always like the U.S. dollar of solemn steady, habitual two color printing also to grow with each passing hour, on 20 yuan of certificates of new edition in 2004, adopted colored shading design; Euro adopt colour transition, designs such as gradual change; Middle 2000 editions Hongkong dollars of row adopt double-colored fine rule doubling design.

Do not adopt the banknote of the false proof design of colored shading, color is too single-minded, from the counterfeit money print principle, does not have the difficulty of multicolor overprint, uses photomechanical production, chemical etching, the intaglio printing of screening just can the pseudo-easily super counterfeit money of producing high fidelity.Though this old-fashioned plate-making technology is divided plate-making, electronic engraving or laser engraving to replace by electricity already, its possibility still exists, and harmfulness, duplicity are very big.

Therefore, colored shading is an extremely effective secondary defense on the banknote picture and text, also is extremely effectively foundation of micro-currency examine technology.

4, special ink

The color of banknote is from printing ink.Banknote printing ink is special ink, and it is different fully with the technical standard of common color printing-ink, and one of difference is that the former does not have impurity, and the latter is contained filler; Banknote ink color extremely abundant (being that form and aspect, saturation degree, lightness all depart from or colour gamut surpasses printing-ink), and adopt nearly tens even tens look spot color printings.CMYK (blue or green, pinkish red, yellow, black) four primary colours chromatographys are all used in the common color printing; Though the counterfeit money of high fidelity adds some spot inks mostly in addition, there is no the essence that changes four primary colours chromatographys, just improve its color rendering effect.On micro banknote tester as seen, " genuine note ink marks beautiful texture bright in luster, limpid such as dyestuff, and dry and astringent turbid dark texture of counterfeit money such as coating; Genuine note engraving gravure ink marks such as jade embossment, counterfeit money does not have this effect ".It all is one of sensitive part of micro-currency examine that the up name of banknote, interarea volume, braille and colored shading etc. are located.

Therefore, special ink is very important the 3rd defence line on the banknote picture and text, also is the very important foundation of micro-currency examine.

5, fine and closely woven pattern

The 4th defence line on the banknote picture and text is fine and closely woven pattern, is used to destroy the sharpness and the color fidelity of counterfeit money.It is formed various groups and spends, rolls up fine and closely woven patterns such as flower, rainbow, microfilm of characters with 20～30 microns wide dark colors (or light color) fine rule.The chromatograp sharpness of am screening can show that its implication is that colored original is decomposed into the pixel of how many sites per square inch with the mesh numerical table, represents with lpi, claims in the industry " line number ".Offset news is used 135 lines usually, colored picture album 175 lines, image 200 lines that high fidelity requires.Because during offset printing can rise greatly in the site, the restriction of alignment precision when being subjected to printing again, the mesh number of amplitude modulation net is difficult to reach 250lpi.Suppose that certain counterfeit money might then have 254 * 254 sites with 254 line screenings in per square inch, 25.4 millimeters ÷ 254=0.1 of promptly adjacent monochromatic site spacing millimeter=100 microns.In other words, have only when distance is greater than 100 microns between two fine rules (primary colours), just can copy this two fine rules; Otherwise, will pile up and blur owing to the site; In like manner, 20～30 microns dark fine rule becomes 100 microns wide lines on the genuine note on counterfeit money.Other colored fine rule is because the polychrome site shows a pixel jointly, and then sharpness is lower.If counterfeit money adopts gravure, its ink cell minimum diameter must be greater than 20 microns these limit, and ink cell is too little, and printing-ink little dot loss can occur because surface tension is difficult to transfer on the paper.Therefore, the group that fine rule is intensive on the counterfeit money spend, roll up flower or dark fine rule place color dense partially and fuzzy, fine rule is sparse or light color place color is light partially or leakage in vain (this also is the object of " at a glance ... ").Desktop publishing system such as computer printer and color copy machine since when printing ink or carbon dust can splash, so splash down many " sites " on every side and reduce sharpness at fine rule.On micro banknote tester, " each local pattern of Renminbi genuine note by strain line form, the lines flow smoothly, microfilm of characters and the intensive place of fine rule are very clear; Counterfeit money but is the site picture group, at fine and closely woven pattern place, or dot loss causes look light or leak whitely, or the site is piled up and is caused look dense or fuzzy; Microfilm of characters can not be shaped; Genuine note gravure ink marks is strain line twitches, the flat stamping counterfeit money have the site do not twitch and the gravure counterfeit money be the site and twitch ".As seen, fine and closely woven pattern is very severe for the destructive power of counterfeit money sharpness and color fidelity.Portrait eye, national emblem, stealthy denomination, various group spend on the banknote, microfilm of characters all is one of sensitive part of micro-currency examine.

Therefore, fine and closely woven pattern is of great use an antiforge function on the banknote picture and text, also is micro-currency examine technology foundation of great use.

The old edition dollar is the model who utilizes the fine and closely woven pattern anti-fake of gravure.If the lawless person adopts not photomechanical production, the chemical etching of screening, the back with intaglio printing just easily puppet produce " high fidelity " or " super " counterfeit money." chase " of the corresponding original copy pixel of this technology color depth is darker, and live width not necessarily changes.Because the pattern of old edition dollar is all with dark printing, so will be thicker than genuine note with the counterfeit money ink marks of this technology printing.On micro banknote tester, can see its strain line and twitch amplitude greater than genuine note, can see that also the three-dimensional configurations such as " faces " on counterfeit money lines top layer is obviously different with genuine note; Adopt the dollar counterfeit money of screening plate-making gravure can have typical case's (amplitude modulation net) lattice point structure feature, the big ink cell degree of depth in the site of corresponding original copy pixel color depth is also darker, so big site can occur piles up little dot loss, its sharpness is slightly poorer than not screening chemical etching, when starting the jumping lamp function of micro banknote tester, be the site and twitch.

Used site " looks and must reach the FMAM screening technology " to Japan's screen can be little of 10.5 microns, has only two to 1/3rd of fine rule width in the fine and closely woven pattern of genuine note, this technology might make traditional offset printing and gravure resolution bring up to more than 300 lines, help improving the sharpness and the color fidelity of counterfeit money, therefore, from now on must be strictly vigilant to this.

6, other

On the banknote except picture and text have the antiforge function of a guiding principle four lines, holographic magnetic fenestration safety line and photochromatic printing ink and just opposing that the impression case also has good antifalse effect.

The holographic magnetic fenestration safety line of the 5th cover new edition Renminbi overall application also is one brand-new defence line, and this safety line is made with special material.As South Korean Won 5000 yuan of certificates of version in 2002 and the 5th cover new edition Renminbi, on micro banknote tester, start when jumping the lamp function, on the safety line magnetic microfilm of characters can be between white gravoply, with black engraved characters and black matrix wrongly written or mispronounced character two states circulation change.This phenomenon is called safety line " light change effect ".The material prescription and the manufacturing technology of this safety line belong to state secret, are that banknote prints scientific and technological new results, and counterfeit money can not follow up.Machine-readable password on this safety line belongs to state secret, micro-currency examine technology can be under the prerequisite that does not relate to state secret correct discriminating.Holographic fenestration magnetic security line has unique antiforge function because of having special light change effect.

Early stage banknote fenestration safety line does not have light change effect antiforge function, as 10000 yuan of certificates of South Korean Won nineteen eighty-three version.Therefore, when certain genuine note fenestration safety line of precognition has light change effect antiforge function, can be used as the reliable foundation of micro-currency examine technology.

Utilize the jumping lamp source of micro banknote tester can differentiate photochromatic printing ink on the banknote.Photochromatic printing ink is more common in digital denomination, when changing the lighting source orientation, is different color and changes.Its material prescription and manufacturing technology belong to state secret, and counterfeit money still fails to follow up, so the photochromatic printing ink of counterfeit money can variable color.

Whether the light that utilizes the micro banknote tester sample window to reveal can differentiate accurately that to seal it is true and false by observing banknote specific pattern pros and cons, and this is a conventional method.

(3) essential distinction between the true and false Renminbi

1, the essential distinction between the true and false Renminbi

In sum, genuine note micro-image structure has " strain line picture group; Engraving gravure ink marks is jade embossment shape, its strain line has the twitch effect; Extraordinary spot ink, ink marks texture is bright-coloured beautiful as dyestuff; The lines flow smoothly for shading, and colored wiring is nature accurately; Fine and closely woven clear patterns such as microfilm of characters; Holographic fenestration magnetic security line has the light change effect " feature, be called for short " strain line structure " feature.Its core is " strain line picture group, an engraving gravure ", and " manual engraving " is its elite.The counterfeit money micro-image has " site picture group; Four primary colours chromatographys; Common printed printing ink, black matter is dry and astringent turbid dark as coating; Pile up or lose in the site at the intensive place of fine rule, and microfilm of characters can not be shaped.The flat stamping ink marks does not have the twitch effect, and what the gravure ink marks was twitched is the site; The fenestration safety line is not had a light change effect " feature, be called for short " lattice point structure " feature.Its core is " site picture group, four primary colours chromatographys ".

The gross differences between the true and false coin picture and text micro-image architectural feature has been created in the false proof design of banknote picture and text.Visual contrast is very big between two kinds of different architectural features, and "Yes" " non-" is clearly demarcated, does not have equivocal part, very easily in recognition.

From the technical standard angle, genuine note and counterfeit money all are chromatograps, and genuine note is the legal tender of government issued.For false proof, government is inevitable secret to formulate special-purpose, different fully with civilian colored printing and same currency printing technology standards system never, the relevant design of specified in more detail, false proof,, every printing condition criteria for classifications such as technology, equipment, raw material, also formulate tight security monitoring system simultaneously.The technology relevant with banknote, equipment, raw material etc. all can not be scattered among the people, and the government of any country of this way is also all the same.Counterfeit money is the common color printed matter, is the duplicate of genuine note.The lawless person is limited by disguise, ageing and practicality, can only utilize civilian colour printing process, equipment crime.This class technology, equipment all conform to colored printing technology international standard system, are inheriting the gene of " site picture group, four primary colours chromatographys " jointly.

Different printing technology standards systems is only very, the essential distinction between counterfeit money, and this difference comes from action by government.The antiforge function of genuine note picture and text is one of these essential distinctions, the difference embodiment of this essential distinction just between true, the counterfeit money micro-image architectural feature, the also key that can evade never of counterfeit money just.As seen, any genuine note all can not have the feature of lattice point structure; The genuine note that has two kinds of architectural features does not simultaneously exist.Same width of cloth banknote different parts has lattice point structure and strain line architectural feature respectively, and the banknote of mending, piece together sign by replacing a damaged part is arranged is the adulterium coin, also is counterfeit money.Any banknote with lattice point structure feature all is a counterfeit money.And the lattice point structure feature of counterfeit money as bion gene, inherent, congenital intrinsic, can't evade.As seen, have " lattice point structure " feature, get final product " putting to death " then and there, need not " bothering about the nationality ", exhausted nothing " suspicion of manslaughtering " as long as detect that banknote.

2, the chaos caused by war current political situation and official's forge money problem

In peacetime, that utilize high-tech manufacturing counterfeit money all is reactionary gang's tissue, criminal gang or lawless person, and they are purpose to make profit specially.This class counterfeit money is called " people's forge money ".Be characterized in adopting civilian chromatic printing equipment to print, its picture and text micro-image has the feature of lattice point structure, make profit to as if vast general public.

In the chaos caused by war current political situation, controlling has the politics of printing the paper money ability, the precedent of military force forge money for political motives that Shi Kejian is also arranged, and this is an extreme case.This class counterfeit money is called " official's forge money ", is characterized in adopting the genuine notes printing equipment to forge, and its picture and text micro-image has the strain line architectural feature, and the target that it destroys is that the finance of hostile nations or hostile force is economical.

On the modern history, Hitler once forged a large amount of sterlings, had been thrown into the international market during the Second World War, in order to buy munitions and goods and materials, caused very big destruction for the financial economy of Britain.In nineteen seventies, the common people of China southeastern coastal areas just once many person-times choose Jinmen, Mazu false Renminbi of coming drifted by wind, public security cadres and police once repeatedly captured a large amount of false Renminbi from special agents sent by America and Chiang Kaishek's case of cracking.Like that according to AIKA (www.ajsc, cn) " counterfeit money type and discrimination method " literary composition is introduced: these counterfeit moneys are " Taiwan version the 3rd cover 10 yuan of certificates of Renminbi and 1 yuan of certificate to family's collection net.Explaining according to criminal is that Taiwan seal paper money factory prints.The method that its printing, mask-making technology and we print paper money factory is similar.From outside watch with genuine note also closely similar, all very approaching as gravure printed hand feel, decorative pattern, color.From paper, watermark is also arranged, discrimination ratio is difficulty.But this counterfeit money also has its tangible characteristics, and is inconsistent as the portrait view and the genuine note of hand engraving ... " it seems that this genus official forge money is the product under the historical conditions at that time.How is problem to differentiate?

For official's forge money, if extremely recognize strain line picture group, engraving gravure be genuine note that is just wrong because official's forge money is different from people's forge money, its duplicity is very big.Fortunately the antiforge function of the manual engraving of genuine note with version uniqueness, the counterfeit money that any technological means is forged can only be not the same similar to genuine note in varying degrees at all.Official's forge money also is not the same with the micro-image of known genuine note on corresponding sampled point.On micro banknote tester, flat shapes such as the color lump of observation hand engraving, the top layer " face " of lines and length, width, radian, turning, also have many identifiable three-dimensional configurations such as thickness, the hollow out depth, concavo-convex degree, side slope gradient, edge smoothness, by to make relevance ratio right with known genuine note, the genuine note counterfeit money, the own shouting that divides.But also has another problem: be to suspect that earlier it is that counterfeit money is differentiated then, know earlier that still it is that counterfeit money is verified then?

On micro banknote tester, the genuine note picture and text micro-image of having got used to resembles household's the face familiarly, and any trickle difference all can cause our vigilance.In other words, find shadow of doubt earlier, relevance ratio is made to differentiating with known genuine note in the back.Not hard to imagine, on micro banknote tester, counterfeit money cans be compared to the stranger, and a glance just can be recognized, and does not need an ear nose mouth to compare one by one, and he and household are not twins after all.

Therefore, utilize the antiforge function of banknote picture and text both can differentiate people's forge money, equally can discriminating official forge money.Briefly, use micro-currency examine technology, can differentiate the true and false of Renminbi and various foreign currencies.The identification result of micro-currency examine technology is accurately and authority.The powerful antiforge function of banknote picture and text has only the ultimate attainment performance of micro-currency examine technology ability, and micro-Jianzhen's mobile phone is one of model who uses micro-currency examine technology.

The innovation theory that the inventor differentiates according to above-mentioned banknote, 200410052017.8) and patent of invention " light-source system of micro banknote tester " (application number: 200510035966.X) etc. multinomial, and further develop micro-Jianzhen's mobile phone in view of the above successively applied for patent of invention " Apparatus for testing paper currency for genuineness " (application number:.It has low, powerful, the easy to use advantage of cost, can accurately differentiate the various counterfeit moneys that any technological means is forged.

Banknote up-sampling point can be chosen arbitrarily, the micro-image difference of different mining sampling point, if the mobile phone authenticating head is nuzzled up and forms a sample line along banknote surface, then LCD demonstrates the micro-image of every bit on this sample line continuously, and is continuous movable colour picture such as TV.

2) differentiate target

The discriminating target comprises: the engraving gravure on the banknote picture and text, colored shading, special ink, fine and closely woven pattern and other.

Responsive especially sampled point on first-selection banknote picture and text during currency examine: as engraving gravure places such as main scape, row name, interarea volume, portrait eye, state's note of the ancient Chinese, braille, stealthy denomination, microfilm of characters; Multicolour pattern and color change colored shading places such as (colored wiring); Fine and closely woven pattern places such as the various groups that are made up of intensive fine rule spend, figure and offset printing microfilm of characters; And holographic fenestration magnetic security line.Color shifting ink (denomination numeral) and pros and cons be to the impression case in addition, even the edge of banknote paper, breach, interface also are important sampled points.Micro-image by the banknote picture and text can accurately be differentiated the various counterfeit moneys that any technological means is forged.

3) result of use

On micro-Jianzhen's mobile phone, can be observed:

Genuine note picture and text micro-image structure has " strain line picture group; Engraving gravure ink marks is jade embossment shape, its strain line has the twitch effect; Extraordinary spot ink, ink marks texture is bright-coloured beautiful as dyestuff; The lines flow smoothly for shading, and colored wiring is nature accurately; Fine and closely woven clear patterns such as microfilm of characters; Holographic fenestration magnetic security line has the light change effect; Color shifting ink meeting variable color; Pros and cons is accurate to the impression case " feature, be called for short " strain line structure " feature.Its core is " strain line picture group, an engraving gravure ", and " hand carving gravure " is its elite.

The counterfeit money micro-image has " site picture group; Four primary colours chromatographys; Scatter various color dots in the shading color lump, the edge indentation, fracture or dislocation are seen in colored wiring more; Common printed printing ink, black matter is dry and astringent turbid dark as coating; Pile up or lose in the site at the intensive place of fine rule, and microfilm of characters can not be shaped.Flat stamping (comprising offset printing, computerized print, color photocopying and digital color printing) ink marks does not have the twitch effect, and what the gravure ink marks was twitched is the site; Holographic fenestration magnetic security line is not had a light change effect; Color shifting ink can not variable color; Pros and cons is to impression case dislocation " feature, be called for short " lattice point structure " feature.Its core is " site picture group, four primary colours chromatographys ".The counterfeit money of various colored banknotes all has above-mentioned feature.

Special look banknote for old edition dollar and so on: adopt " offset printing, (after screening plate-making) gravure; Or computerized print, color photocopying; Or digital color printing " counterfeit money forged, all have the feature of lattice point structure.Adopt " photo colour separation; not screening chemical etching (this is original mask-making technology; eliminate already; but possibility also exists) plate-making back autogamy spot ink; intaglio printing " counterfeit money, no lattice point structure feature, but its ink marks three-dimensional configuration and printing ink tone, obviously different with genuine note, its twitch phenomenon is more violent than genuine note.

For the super counterfeit money of following version: hold the art means and be used to forge following edition super counterfeit money if the lawless person adopts " high-fidelity standard six color inks " closing ceremony of Japanese screen company " look must reach FMAM mix screening technology " and U.S. Pan Tong company to integrate other, because above-mentioned two print field new technologies are just improved the print effect of coloured image, do not change the essence of " site picture group, four primary colours chromatographys ", thereby the counterfeit money of being printed will have the feature of lattice point structure.

For during the war years, official's forge money that may occur on the market: because the picture and text of genuine note hand engraving, intaglio printing have unique version uniqueness antiforge function, so the three-dimensional configuration of ink marks must be different with known genuine note in its picture and text micro-image.

4) authenticity of banknotes judging standard

On micro-Jianzhen's mobile phone, the authenticity of banknotes judging standard is: " according to the micro-image of banknote to be tested picture and text, micro-image is no abnormal and to have the strain line architectural feature or be the banknote that strain line twitches be genuine note; Different with the corresponding sampled point of known genuine note or have the lattice point structure feature, no matter and its banknote of whether twitching all is a counterfeit money ".This judging standard is applicable to the various machine-processed counterfeit money that any technological means is forged, and equally also is applicable to various adulterium coin; It not only is suitable for Renminbi, also is suitable for various foreign currencies.In addition, also variable value warrant and the certificates such as train ticket, stamp, treasury stock of being common to.

Gross differences between the micro-image architectural feature of true and false coin is the embodiment of banknote graphic anti-counterfeiting function, is one of essential distinction between true and false coin, and it comes from action by government, and therefore, this difference is different fully and same never.It is the Achilles' heel of counterfeit money, also is the fundamental basis of micro-currency examine technology.Micro-currency examine technology and biological DNA paternity test have similarity.

Therefore, micro-Jianzhen's mobile phone can be differentiated any banknote of any country, and its identification result is accurately and authority.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
