Interference code may include black ink layer and colorless oil layer of ink, the black ink layer and the colorless oil layer of ink according to
It is secondary to be layered in the base, and the colorless oil layer of ink generates visible fluorescence under excitation light source irradiation.
The conventional ink for printing standard code may be used in black ink layer, and colorless oil layer of ink may be used stealthy red
Outer ink or stealthy UV inks are formed.
Stealthy UV inks can send out visible light (400-800nm) using ultraviolet (200-400nm) irradiation excitation
Ink.Stealthy UV inks are water white transparency under normal conditions, and the face such as red, yellow, green, blue can be shown under ultra violet lamp
Color.Such as the Y4-100 UV inks of Guan Chuanyijia Science and Technology Ltd.s may be used, appearance is colourless, with 365nm fluorescence
When Deng irradiating, display green；Y4-101 UV inks, appearance are colourless, when with 365nm fluorescent lamps, can be shown red
Color.
The colourless stealth in normal state of stealthy infrared excitation ink, excitation light source irradiation under can present it is red, green,
The different color such as indigo plant, Huang.Dyestuff in ink needs have a strong absorbent to infrared light, also to have good color fastness, resistance to
Hot, chemical-resistant.There is the chemical combination suitable for configuring stealthy infrared printing ink in phthalocyanine, naphthalene phthalocyanine, aromatic amine, methine dyes
Object, prepare stealthy infrared printing ink solvent may be used ethane, tetrachloro-ethylene, toluene, chlorobenzene, cyclohexanone, ethyl alcohol or they
Mixture.Some additives can also be increased, for example, linseed oil and tung oil, they can improve the rheological equationm of state of ink (as glued
Degree), and the rate of drying of controllable ink, plasticizer, surfactant, catalyst and antioxidant etc. can also be added.
In addition, the Y0-102 infrared printing inks of Guan Chuanyijia Science and Technology Ltd.s for example may be used, appearance is colourless, is used
When 980nm laser light irradiations, it can be displayed in blue；Y0-101 infrared printing inks, appearance is colourless, with 980nm laser light irradiations
When, it can be displayed in red.
If ultraviolet irradiation time is very of short duration when reading security code or reads security code in enclosure space, can also adopt
Use ultraviolet ink.Because long-term irradiation or strong ultraviolet light have injury for human body, it is advantageous to use infrared excitation ink.
When interference code includes black ink layer and colorless oil layer of ink, preferably by the black ink layer of standard code and interference code
It is printed using same ink, then, is formed using above-mentioned stealthy infrared printing ink or UV inks in interference code position.
The very thin thickness of colorless oil layer of ink, can not discover that there are thickness with other regions if even if being covered in people in black ink layer
Difference.
In addition, a variety of stealthy dyestuffs may be used in colorless oil layer of ink so that printing image can use multi-purpose mode into
Row detection.Such as with metal phthalocyanine IR fluorescent dyes be the first stealthy dyestuff, this dyestuff is under Infrared irradiation, Ke Yifa
Go out fluorescence；Using cumarin, quinolone or pyrene as the second dyestuff, this dyestuff can also be sent out glimmering under ultraviolet light
Light.Therefore, including the security code of this compound invisible printing ink can both be detected under infrared light system irradiation, can also be in ultraviolet light
It is detected under irradiation system to obtain relevant information.
In above example, interference code part is divided into black ink layer and colorless oil layer of ink, however, interference code can also
It is formed by the black infrared printing ink including infrared excitation fluorescent material or the black UV inks including ultraviolet excited fluorescence powder.
The grain size of infrared excitation fluorescent material or the ultraviolet excited fluorescence powder can be 10-1000nm, such as can be
20nm、30nm、40nm、50nm、60nm、70nm、80nm、90nm、100nm、110nm、120nm、130nm、140nm、150nm、
160nm, 170nm, 180nm, 190nm, 200nm, 300nm, 400nm, 500nm, 600nm, 700nm, 800nm or 900nm, preferably
For 100-200nm.
The grain size of fluorescent powder is reduced in ink phase, and the luminous efficiency of fluorescent ink improves.It is tiny when grain size is less than 20nm
Fluorescent powder be easy to reassemble or flocculate, grain size be more than 1000nm when, typically, relative intensity of fluorescence reduce, do not allow
Enough fluorescence is easily obtained from interference code, thus leads to that 2 D code information cannot be read.
Interference code is preferably formed by the black infrared printing ink including infrared excitation fluorescent material.
Weight percent of the infrared excitation fluorescent material in black infrared printing ink can be 10-40%, such as can be
15%, 20%, 25%, 30% or 35%.In a certain range, with the increase of fluorescence powder content, pigment particles in medium
Percentage increases, and the relative intensity of fluorescence of IR fluorescence ink also gradually increases.Infrared excitation fluorescent material is in black infrared printing ink
In weight percent to be 10-40% can meet the reading of standard bar code information.It is glimmering when the content of fluorescent powder is more than 40%
Dispersibility of the light powder in ink system be not good enough, causes to be easy to happen Quenching when fluorescent molecular concentration is high, cause relatively glimmering
Luminous intensity declines, fluorescence lifetime reduces.
The grain size of preferred infrared excitation fluorescent material is 150-180nm in the present invention；Infrared excitation fluorescence is red in the black
Weight percent in outer ink is 30-35%, is fluorescent powder tool within the scope of 150-180nm and weight content in above-mentioned grain size
There is good dispersibility and relative intensity of fluorescence is also larger.It can not only be easy to obtain two dimension in infrared excitation as a result,
The relevant information of code, and can ensure that Quick Response Code has longer service life.
As the carrier of black infrared printing ink, the effect of film-forming resin is to connect powdered solid pigment particle
Come, and it is made to be eventually adhering on stock.
It is preferred that using poly- polyurethane resin as film-forming resin, this is because containing amine in the molecular structure of polyurethane resin
Ester bond, intermolecular there are very strong Hyarogen-bondings, easily form hydrogen bond with the fluorophor under ground state before receiving infrared excitation, make
It obtains molar absorption coefficient to increase, i.e. influx and translocation, therefore the relative intensity of fluorescence of IR fluorescence ink obtained is higher.And all
As acrylic resin molecular structure in contain carboxylic acid group, be fluorescence colour killing group, can offset or inhibit the generation of fluorescence, because
The relative intensity of fluorescence of this IR fluorescence ink obtained is relatively low.
Different film-forming resin contents also have a significant impact for the relative intensity of fluorescence of IR fluorescence ink, this is because with
The increase of film-forming resin content, ink system viscosity can increase, and reduce the rate of excited state molecule vibration and rotation, to
Its collision rate with other pigment particles is reduced, the relative intensity of fluorescence of IR fluorescence ink is improved.
Also contain black pigment particle, weight hundred of the polyurethane resin in black infrared printing ink in IR fluorescence ink
Divide than being preferably 5-20%, more preferably 15-18%, fluorescence intensity maximum at this time.When film-forming resin content is more than 20%,
With the increase of its content, the region being gradually reduced is presented in relative intensity of fluorescence, this is because film-forming resin hinders fluorescence
The absorption of confrontation light, to weaken relative intensity of fluorescence.
The weight percent of black ink in IR fluorescence ink be 30-55%, for example, 35%, 40%, 45%
Or 50%, can also include ink quick dry agent, printing ink reducer etc., the content of ink quick dry agent can be 1-2%, ink dilution
Agent 1-5%.
In addition, the TiO that grain size is 20-60nm can also be added in IR fluorescence ink2, such as 30,40 or 50nm,
Weight percent in IR fluorescence ink can be 0.1-0.5%, can greatly improve the quick-drying of ink, so as to so that
IR fluorescence ink carries out high speed printing to interference code and standard code simultaneously with common ink.Therefore, interference code uses black oil
Layer of ink is compared with colorless oil layer of ink, and interference code is preferably formed by the black infrared printing ink including infrared excitation fluorescent material, so as to
To improve production efficiency, reduce cost.

To be infrared ray and/or actinolyte.
Due to using RF transmitter in many ground scanning means, it is therefore preferable that using RF transmitter.
In addition, the anti-counterfeiting system further preferably includes visible light emitter, and the light of visible light emitter transmitting
Color and the visible fluorescence solid colour.Since generate is coloured visible glimmering to interference code under laser light source irradiation
Light, accordingly, it is possible to cause when irradiation identifies security code, there is more apparent area in the reflected light of interference code and white space
Not.Therefore, preferably further include visible light emitter in order to improve antifalsification, and the light of visible light emitter transmitting
The solid colour of color and the visible fluorescence, in the case, since the color and white space of the light of interference code transmitting are anti-
The solid colour penetrated, lawless people are difficult to find the difference in standard code region and interference code region, increase imitated difficulty.
Furthermore, it is possible to dedicated closing barcode scanning device be arranged, i.e., by RF transmitter or actinolyte and barcode scanning
Device is arranged within the enclosed space, it would be desirable to the antifalsification label of barcode scanning is placed into the enclosure space, when barcode scanning, operating personnel or
