Niaj hnub no, nrog rau kev sib txawv ntawm kev ruaj ntseg thiab tiv thaiv cwj pwm, ntau yam tshiab tiv thaiv kev yees cwj pwm yog tawm ib qho tom qab lwm qhov, qhia txog ib qho teeb meem ntawm kev tuaj yeem tawg. Qhov tseem ceeb rau kev siv tshuab tiv thaiv kev lag luam yog los ncua lub sij hawm thiab kev tiv thaiv ntawm kev tiv thaiv kev siv dag siv, uas yog lub hom phiaj ntawm lub tswv yim tiv thaiv kev lag luam. Cov cuab yeej siv tiv thaiv kev lag luam tawm xws li: tawm tsam kev lag luam ntawm luam tawm, tiv thaiv cov ntawv luam tawm, kev tiv thaiv kev luam tawm ntawm cov ntawv luam tawm thiab kev tiv thaiv kev luam tawm. Ntawm lawv, txoj kev loj hlob ntawm luam tawm tus lej los tiv thaiv kev lag luam yog zoo heev, thiab daim ntawv thov yog ntau dua.
1. Cov txheej txheem cwj pwm tsis zoo ntawm kev cuav
Cov npe hu ua "anti-counterfeiting" yog ib lub cim tshwj xeeb luam tawm uas ua los ntawm tus txheej txheem tshwj xeeb los ntawm kev ntxiv ib qho kev kawm tshwjxeeb los tiv thaiv cov khoom ntiag tug rau tus lej yuag. Cov txheej txheem cuav rau hauv kev lag luam yog tsuas yog cais tawm hauv cov hom nram qab no raws li lawv cov haujlwm tiv thaiv kev ua txhaum cai: 2 fluorescent inks thiab phosphorescent inks. 3 xim kua mem sau. 4 Txoj hlua coj los hloov tshuaj. 5 hnub ci tshuab ua xim hloov xim. 6 ntse ntse hauv counterfeiting. 7 infrared inks. 8 nanometer number case. Ntawm cov tshuaj, cov xim xim hloov xaj yog ib qho tseem ceeb ntawm tus cwj mem los tiv thaiv, thiab yuav muab faib ua dua ntxiv: ib thermochromic number case, xim xim nrig xim, xim voj voos xim, zoo li. Cov tshuaj yeeb-xim hloov cev yog cov tshuaj muaj ntxiv uas muaj ntxiv rau cov cwj mem raws li qee qhov kev mob (xws li teeb, cua sov, av noo, siab, thiab lwm yam), thiab ntau yam tshuaj lom neeg muaj peev xwm tshwm sim tau, lub hom phiaj. Tus cim decolorizing yog ib ceg ntawm cov xim uas hloov xim reactive, uas yog ib qho kua number case uas yooj yim dua lossis yaj los ntawm dej los yog tshuaj.
2. Kev faib tawm ntawm cov phuaj nyuaj
① Cov dej uas muaj dej-decoloring tseem muaj lub npe hu ua kua roj ntub dej. Txoj cai tiv thaiv counterfeiting yog tias cov ntaub ntawv uas muaj xim muaj xim nrog cov kev hloov pauv ntawm cov av noo. Nws tuaj yeem raug tshem tawm los ntawm dej los yog tshuaj dawb, thiab feem ntau yog cov dej-soluble uas muaj oxidizing tus neeg sawv cev lossis ib tus neeg txo kev quab yuam. Tus cwj pwm phem tiv thaiv no yog tias lub xeev qhuav tsis muaj xim thiab lub ntub lub xeev pib xim. Cov ciav dej uas raug muab tshem tawm yog ntxiv mus rau hauv kev hloov hauv siab, ua rau tsis muaj zog, thiab muaj dej ntom-xoos, thiab muaj plaub xim xiav, ntsuab, dub thiab liab.
● Cov xim ntawm tus cwj mem xauj rov tom qab hloov xim ntawm cov xim tsis muaj xim tom qab cov dej ntws tawm. Tom qab cov dej tuaj yeem ntub tas, xim tseem yuav rov qab los. Cov xim yog dawb → tsis muaj, tsuas yog silkscreen lossis gravure. Rau silk screen luam ntawv, nws pom zoo kom siv 200 mesh screen printing. Lub thicker zoo dua.
● Raug cwj mem xaj xaj xaj: Nws yog ib qho xim oily. Nws hloov ntawm cov kob los pleev xim rau tom qab tsis muaj dej. Tom qab cov dej tuaj yeem ntub lawm, cov xim tsis rov qab los rau cov xim qub. Qhov xim yog dub → tsis muaj, liab → tsis muaj, xiav → tsis muaj, ntsuab → tsis muaj. Tsuas silk screen printing, gravure printing, luam ntawv yuav tsum yog thinner, ci xim, zoo fading nyhuv, xws li silk screen luam ntawv pom zoo kom siv 350-420 mesh npo luam ntawv.
● Cov av ntom nti tsis zoo, qhov xim liab, daj, xiav, ntsuab, thiab lwm yam, thiab tsuas tuaj yeem luam tawm los ntawm dej-based printing.
② organic solvent decolorizing number case, xws li cawv, roj, benzene, thiab lwm yam. Lub hauv paus ntsiab lus ntawm cov organic solvents thiab kev tuaj dej ntawm lub cev tsis zoo, thiab lawv tag nrho cov xim raws li kev sib nrig sib xyaw ntawm cov tshuaj coj los.
③ Dej xa thiab cov tshuaj hnyav ua kua hauv kev xa tawm yog hu ua "composite decompression inks". Cov kua chiv ntawm cov kua chiv muaj peev xwm tuaj yeem ua rau cov kua tshuaj, cov tshuaj dawb thiab cov organic solvent mus cuag lub hom phiaj ntawm cov xim txo. Feem ntau, cov tshuaj tsis muaj zog tuaj yeem tshem lub thwj rau ntawm daim ntawv hla tebchaws thiab tus cwj mem kua dej-soluble cwj mem. Yog tias koj xav tshem tag nrho los yog ib feem ntawm daim npav pleev npav, koj tuaj yeem hle tus qauv hnyav. Txawm li cas los xij, cov tshuaj no yuav tsis muaj teebmeem rau txhua yam luam ntawv thiab tus cwj mem hauv. Ntawm lawv, dub number case yog raws cov pa, thiab ib qho hnyav zog tsis tuaj yeem tswj nws. Tus cim decolorizing kem yog ib qho kev tshwm sim ntawm txoj kev loj hlob ntawm cov cwj pwm counterfeiting inks, vim hais tias tus cwjpwm tivthaiv tus cwjpwm tivthaiv tsis tuaj yeem tsuas cuam tshuam cov kev pabcuam lub neej ntawm tus cwj mem los tiv thaiv, tabsis tseem ua rau cov nyom tiv thaiv tsis zoo.
④ binary anti-counterfeiting number case, uas txhais tau hais tias lub cim decolorizing muaj ib cov tshuaj fluorescent, thiab nws yuav yooj yim distinguished txawm los yog tsis qhov hnyav tau siv nyob rau hauv irradiation ntawm ultraviolet rays. Raws li, cov ntiv taw sab nraud cov hauv plab muaj cov thooj txeem muag pom thiab muaj ib qho kev tiv thaiv fluorescent. Nyob rau hauv pom lub teeb irradiation, cov thaub qab tsis zoo li muaj nyob rau hauv tag nrho, tab sis thaum raug mus rau ultraviolet lub teeb, lawv muaj cai los ntawm tib neeg qhov muag. Muaj ntau cov ntawv luam tawm ploj lawv cov fluorescence thaum siv tshuaj dawb. Yog li, peb tuaj yeem siv cov fluorescent inks los ua ib qho kev ntsuam xyuas seb cov tshuaj dawb tau kuaj los ntawm lub tshuab.
3. Daim ntawv thov achromatic number case
Tam sim no, cov dej hauv tawm hauv cov dej yog cov feem ntau siv cov roj, feem ntau siv raws li keeb kwm ntawm kos npe ntawm ib daim ntawv, thiab raug siv hauv qab cov zauv yooj yooj yim. Ntxiv nrog rau tus cwj mem xaj xaj yog xim keeb kwm yav dhau, thaum lub substrate yog bleached, tshuaj lom neeg yuav tshwm sim los ua rau xim av me ntsis. Nyob rau hauv cov ntaub ntawv uas yuav tsum tau txheeb xyuas, xws li cov duab hauv daim passport, lub composite yog laminated nruab nrab ntawm cov ntawv lo thiab cov ntawv ci rau cov ntaub ntim khoom, thiab tus cwj pwm xiav dej raug luam tawm ntawm sab hauv sab hauv cov ntawv ci kom nws tau yuav kuaj tau. Muaj dej.
Muaj ntau cov cim tsis muaj dej tsis raug luam tawm nrog dej-decoloring inks uas txuas rau sab hauv ntawm lub xov tooj loj los yog ib qho chaw sab nraum lub roj teeb. Thaum lub logo tsis raug dej los yog ya raws, cov duab ntawm daim duab meej meej thiab yuav tsis ploj lossis hloov xim. Thaum cov dej tau ntsib, cov xim ntawm daim duab yuav kis tau ntawm ntug thiab tsis tuaj yeem txum tim rov qab. Nws tuaj yeem siv los ua ib lub cim rau kev thauj mus los, cia thiab siv cov khoom xws li cov khoom siv hluav taws xob. Tam sim no, ntau lub xov tooj txawb manufacturers tau txais qhov kev lag luam no tsis tshua muaj dej tsis zoo. Lub hom phiaj no kuj tuaj yeem txiav txim tau qee cov lus nug thiab muab pov thawj ua pov thawj.
Nyob rau hauv luv luv, vim yog nce qib ntawm counterfeiting thiab counterfeiting ntawm daim pib thiab khoom trademarks, thiab ntau tus cuav, tus tshiab anti-counterfeiting tshuab tau nce, thiab authenticity ntawm tus kwv yuav tsum muaj kev tiv thaiv yog yuav tsum tau ceev nrooj, pheej yig thiab raug xom lees, thiab cov cwj mem los tiv thaiv kev ua yeeb yam plays lub luag haujlwm tseem ceeb. Lub luag haujlwm. Achromatic inks kuj tau tawm suab. Txawm hais tias tam sim no achromatic number case tau zoo heev tsim thiab applied rau lub neej, vim cov mob ntawm kev npaj thiab soj ntsuam ntawm tus achromatic number case, nws tsis tau ua ntawv thov rau txhua teb zoo li lwm cov phev. Txawm li cas los xij, vim tias cov cuab yeej siv ua ntej dhau los, ntau cov teeb meem yuav daws tau, thiab peb ntseeg tias qhov kev yoojyim siv cwj pwm yooj yim no yuav yog ib qho tseem ceeb ntawm kev siv tshuab ciam av tawm tsam.
