Requirements
Theanti-counterfeitinglabelisoneoftheanti-counterfeitingtechnologyproducts(by2020,thereare6typesaccordingtothenationalstandardclassification).Theanti-counterfeitingthinksthattheproductshouldfollowtheanti-counterfeitinglabelwhenleavingthefactory.Eighttechnicalrequirementsfollowedatthetime:
1.Uniquenessofidentity:theuniquenessandnon-transferabilityofanti-counterfeitingidentificationfeaturesofanti-counterfeitingtechnologyproducts.Forexample,digitalanti-counterfeitingcanachieveoneidentitycodefortheanti-counterfeitingmarkofacommodity,andeachanti-counterfeitingmarkcanonlybeusedonceandcannotbetransferred.
2.Stableperiod:Theshortesttimethattheanti-counterfeitingidentificationfeaturesofanti-counterfeitingtechnologyproductscanbemaintainedundernormalconditionsofuse.Forexample,fluorescentinkandtemperaturechangeinkhaveadecayperiod.
3.Securityperiod:Undernormalconditionsofuse,theshortesttimefortheanti-counterfeitingidentificationfeaturesofanti-counterfeitingtechnologyproductstobesuccessfullyimitated.Thisiswhatcustomerscareaboutmost,andthemanufacturershouldproposeacommitmentperiod.
4.Anti-counterfeitingstrength:thedurabilityandreliabilityofthefunctionofidentifyingauthenticityandpreventingcounterfeiting.Anti-counterfeitingstrengthconsistsoffourelements:thenumberofanti-counterfeitingidentificationfeatures,thenumberofexclusiveanti-counterfeitingtechnologies,thedifficultyofimitation,andthecostofimitation.
5.Applicationadaptability:theabilityofanti-counterfeitingidentificationfeaturesofanti-counterfeitingtechnologyproductstoadapttotheuserequirementsofthesubjectmatterorserviceobject.
6.Recognitionperformance:Theanti-counterfeitingidentificationfeaturesofanti-counterfeitingtechnologyproductscanbecorrectlyidentifiedbythesensesormachines(instruments)withintherequiredidentificationtime.Thefirst-linerecognitionemphasizesthecommonknowledgeofanti-counterfeitingfeatures,whichcanberecognizedbythesenses;thesecond-linerecognitionemphasizestherecognitionbysimpleinstruments(suchasmagnifyingglass,laserpointer,ultravioletfluorescencediscriminator,etc.);thethird-linerecognitionemphasizestheuseofspecialinstruments(suchasDNAidentification))Isidentifiedbyexpertsasthebasisforjudicialjudgment.Two-lineidentificationandthree-lineidentificationemphasizetheimplicitnessofanti-counterfeitingidentificationfeatures.
7.Useenvironmentrequirements:theanti-counterfeitingperformanceofanti-counterfeitingtechnologyproductsshouldbeabletomeetthenormaluseenvironmentrequirementsofthesubjectmatter.
8.Technicalsecurityandconfidentiality:Thetechnologyfordesigningandproducinganti-counterfeitingtechnologyproductsshouldhavesecurityandconfidentiality.Inaddition,theeconomiccostadaptabilityshouldbeconsidered,thatis,theusecostshouldbereducedasmuchaspossiblewhilemeetingtheanti-counterfeitingtechnicalrequirements.

Commonlyusedtechnology
Paper
(1)Fibrepaper
Whenmakingpaper,useredandblueetc.Coloredfibersorcoloredflakes(dots)aremixedintothepulp,orsprinkledonthesurfaceofthepaperbeforethepaperisnotshaped,andthereisfluorescentreflectionunderultravioletradiation,sothatthepapercontainscoloredfibersthataredifferentfromthepaperitself.Theredandbluefiberyarnsandcoloreddotsmixedintothepulpincludecoloredfibersandcolorlessfluorescentfibers.Theformercanbeseenonpaperwiththenakedeye,andthelatterandthecoloreddotsmustbevisibleunderultravioletradiation.Thecolorsarered,blue,orange,etc.,andtheshapecanbethickorthin,longorshort.
(2)Anti-counterfeitingholographicpaper
Holographicproductsbasedonpaperaredividedintotransfertypeandnon-transfertype.Laseranti-counterfeitingtechnologyiscombinedwithpapertomakeanti-counterfeitingpaper.Thefirstisthetransfermethod:usingholographicanti-counterfeitingtechnologyandspecialequipment,themoldedholographicimagetransfermethod(hotstamping,compositepeeling,UVlightcuring,etc.)ispartiallyorcompletelytransferredtopaper.Thesecondisthedirectplatingmethod:applyapolymercoatingonthepaperandplatealuminumdirectly,andthenmoldtheholographicimage.
(3)Watermarkpaper
Watermarkpaperispaperwithembossed,see-through,touchableimage,barcode,etc.Thebanknoteuseswatermarkanti-counterfeitingtechnology.Becausewatermarkscannotbereproducedbyphotocopiers,scanners,etc.,theiranti-counterfeitingeffectsarehighlyvalued.Nowadays,theapplicationscopeofwatermarkinghasexpandedtovaluablebills,certificates,andevenbooksandperiodicals.Watermarkingistheuseoftechnologytoembedtherequiredlogos,patterns,etc.intothepaperduringthepapermakingprocess,suchasinstallingapre-designedwatermarkgraphicprintingplateonthescreen,orpressingitthroughaprintingcylinder.Duetothedifferentheightsofthepicturesandtexts,thepulpwillformcorrespondingdensitieswithdifferentthicknesses.Afterthepaperisformed,thedensityofthepulpatthepicturesandtextsisdifferent,andthelighttransmittanceisdifferent.Therefore,theoriginaldesignpicturesandtextscanbedisplayedduringlighttransmissionobservation.Theblackandwhitewatermarkistothickenorthinthepaperlayeraccordingtothestep.
Therearethreetypesofwatermarks:fixedwatermark,semi-fixedwatermarkandnon-fixedwatermark.

Layereddyedwhitepaperboardismadebysuperimposingmultiplelayersofpulpduringmanufacture,andtheinnerlayerisdyed.Thesurfacelayerandthewhitepaperboardarenotthedifference.Thenumberofdyeinglayersandcolorsequencecanbeindividuallydesigned,andasinglemulti-colorfibercanbeaddedtoeachpulp,whichisconducivetodistinguishingtheauthenticity.Duetothecomplexprocessandhugeinvestment,itisdifficulttocounterfeit.
Inktype
Addsomespecialencryptionformulatotheinktodistinguishitfromordinaryink.Accordingtothedifferentadditivesintheinkandthedetectionmethod,theanti-counterfeitinginkcanbedividedinto:fluorescentink,infraredink,temperature-inducedchangeableink,photo-inducedchangeableinkandanti-copyink,etc.
(1)Ultravioletfluorescentink:Accordingtothecoloroftheinkitself,itcanbedividedintotwotypes:coloredfluorescentinkandcolorlessfluorescentink.Allofthemneedtoshowfluorescenceunderultravioletradiation.Sinceultravioletraysaredividedintolong-waveandshort-wave,fluorescentinksarealsodifferent,andlong-waveultravioletinksaremorecommonlyused.Theproductionprocessoffluorescentinkshasstrictrequirements.Somelow-qualityfluorescentinkscompeteinthemarketatlowprices,andtheiranti-counterfeitingperformanceisverypoor,whichoftencorruptsthereputationoffluorescentinks.Payattentiontothemwhenpurchasing.
(2)Daylight-excitedcolor-changingink:anti-counterfeitinginkthatcanemitvisiblelight(400-800nm)undersunlight.
(3)Infraredanti-counterfeitingink:Itismadebyaddinginfraredabsorbingsubstancesintotheink.Becauseinfraredinkabsorbsinfraredrays,ifthisinkisusedinacertainpartoftheprintedmatter,itwillnothaveanyreactionundersunlight,butunderinfraredirradiation,correspondingsignalsordarkgraphicscanbeobserved.
