Tsis ntev los no, luam tawm luam pib sau nrog cov ntawv tsis substrates, uas pom cov teebmeem luam tawm tshwj xeeb. Qhov no yog qhov tshwj xeeb luam tawm tshwj xeeb. Muaj ntau hom kev luam tshwj xeeb, feem ntau yog cov hauv qab no:
1. luam tawm ultraviolet (UV)
Qhov no yog ib txoj kev luam tawm uas tus cwj mem yog qhuav los ntawm ultraviolet irradiation, thiab tus cwj pwm uas siv los ua tus cwj pwm xeb ultraviolet. Thaum tus number case yog irradiated nrog ultraviolet lub teeb, nws yuav tau hardened hauv ib qho instant, thiab lub zog ntawm tus cwj pwm zaj duab xis yog loj. Yog li, kev luam ntawv xws li ntawv ntim khoom siv pheej yig tuab daim ntawv tshuaj txhuam hauv ob sab phlu, hluavtaws ntawv uas tsis yog tus cwjpwm ntim khoom ntiag tug xav tau ceev kom qhuav luam ntawv, yas. Kev luam ntawv, kev lag luam daim ntawv luam tawm, thiab kev luam ntawv yuav tsum yog ib qho nyuaj hlau zaj duab xis xws li ink film yog tsim dua. Qhov tsis zoo yog tias qhov tshwj xeeb hnyav hauv UV number case yuav swell cov ntawv xov xwm thiab cov menyuam. Yog li, yuav tsum siv cov khoom tshwj xeeb. Ink prices yog kim thiab tsis zoo fwm, uas kuj yog ib qho tsis zoo.
2. tshuaj lom neeg luam tawm
Feem ntau ntawm hom luam ntawv no yog siv rau cov khoom siv ua kom zoo nkauj vim hais tias muab ib qho tshuaj tsw qab rau tus qauv nce ntxiv qhov nqi ntawm daim ntawv. Cov tshuaj tsw qab no yog ua los ntawm cov khoom siv ncaj qha rau cov kua tshuaj. Qhov tsos zoo ib yam li cov cim zoo li tus cwj pwm, tab sis nws pheej tsis yooj yim aroma kav ntev ntev. Cov tshuaj tsw qab ntawm tus cwj pwm yog encapsulated thiab sib xyaw rau hauv los ntawm microcapsules, thiab thaum twg cov ntaub ntawv luam, siv cov microcapsules los ntawm tes los yog lwm cov ntaub ntawv ua rau cov ntxhiab kom maj mam txeej thiab emit ntxhiab.
3. Fluorescence thiab lub teeb cia luam ntawv
Tom qab tus cwj mem absorb cov ultraviolet teeb, nws tau txais pom teeb thiab ua rau muaj kev hloov hauv kev piam sij kom pom tias muaj fluorescence. Kev luam tawm nrog tus lej no yog hu ua fluorescent printing. Tom qab tus cwj mem tso tawm tuaj, lub teeb tuaj yeem muab cia rau hauv qhov chaw tsaus, thiab luam tawm nrog tus cwj pwm hu ua lub teeb cia luam ntawv. Cov teebmeem kev pom ntawm cov khoom luam tawm ob no zoo dua. Yog li ntawd, lub zog ntawm lub zog thiab lub hau ntawm tus dej luam tawm.
Txawm li cas los xij, fluorescent pigments thiab pigments lub teeb pigments kim kim, thiab lawv cov phev tsis zoo printing. Yuav ua kom muaj xim muaj txiaj ntsig thiab pom kev zoo, nws yog qhov yuav tsum tau ua kom lub plhaub ntim quav. Feem ntau, xws li cov thauv sab hauv plab tsis muaj zog thiab kev tu xyuas yuav tsum tau ua nyob rau hauv tej cheebtsam uas siv cov qauv siv li no. Tsis tas li ntawd, thiaj li yuav ntxiv tau zoo ntawm cov teeb meem ntawm cov ntawv luam tawm, nws yog ib qho tsim nyog siv pearlescent number case (pearl number case) rau pearl printing.
4. nqa luam tawm
Cov txheej txheem luam ntawv yog siv rau kev luam ntawv xws li Braille embossing, thiab cov qauv luam tawm tag nrho los yog ib nrab tsa, thiab muaj cov teebmeem kev pom thiab cov kev xav hauv lub hlwb. Thaum luam ntawv, ib tus neeg sawv cev ua tus ntiav loj uas ua rau cov qauv siv luam ntawv yuav siv tau. Tom qab cov cua sov, tus neeg ntxhib foaming nthuav dav kom cov qauv siv pa taws ua ke (foaming printing), thiab cov hmoov txhuas yuav tau raus rau hauv cov qauv ntawm daim qauv, thiab tom qab ntawd Nws rhaub thiab yaj, thiab tom qab nws yog adhered rau tus qauv, nws yog txias thiab solidified tsim ib lub nyem, thiab ib lub thwj yog tsim nyob rau sab nraum qab ntawm cov ntawv luam tawm teeb meem los tsim ib qho kev pab.
Feem ntau, npuas luam ntawv thiab stamper luam ntawv yog kim pheej yig, tiam sis cov qauv ntawm cov qauv protrusion me me, thiab cov kav ntev yog tsawg. Txawm tias cov hmoov txhuam hniav luam tawm tau kov cov teeb meem saum toj no, cov txheej txheem yuav nyuaj thiab kim heev. Cov kev tsim nyog yuav tsum raug xaiv raws li lub hom phiaj ntawm kev siv.
5. OCR (optical character recognition device), OMR (optical identification device) luam tawm
Tsis ntev tas los no, nws tau pib ua cov txheej txheem xws li cov tshev mis mus thiab cov xa tuaj hauv subpoenas hauv computer Oikawa OCR thiab OMR. Thaum siv cov cuab yeej no, nws muaj ob txoj kev ntawm cov ntawv nyeem yooj yim thiab paub sau cov ntawv nyeem. Cov kab ntawv sau feem ntau yog luam tawm nrog cov cwj mem zoo. Txawm li cas los xij, muaj kev to taub yuam kev thaum nyeem ntawv, tab sis ib tus neeg paub txog txoj kev luam tawm los ntawm tus lej (luam ntawv number case) uas tus ntaus cim tsis pom. Txij li cov xim uas siv tau yog txwv rau thaj tsam OCR uas siv siv, qhov kev xaiv ntawm cov xim muaj nqi heev. Tsis tas li ntawd xwb, vim muaj xim hloov ntawm hnub luam ntawv luam ntawv, cov ntawv luam ntawv yog lo av thiab ua rau kev nkag siab tsis zoo, thiab nws yog qhov tsim nyog los tswj cov kev tswj xyuas.
6. qib siab txhais, sib nqus npo luam ntawv
Hauv qhov teeb meem uas siv lithographic uas twb muaj lawm, uas ua rau kom muaj ntau tshaj 300L raws li 175L, nws yog hu ua high-txhais ntawv. Sib nqus npo luam ntawv yog tsim los tsim cov dots ua zoo heev txhua hnub tsis muaj qhov luaj li cas. Qhov txo ntawm Hawj Haum yog ua tiav los ntawm qhov nce lossis txo ntawm tus naj npawb ntawm cov xws li cov dots.
Txij li cov peev txheej txo ntawm cov nplua feem ntawm cov ntsiab lus hauv qhov kev txhais ntawv siab yog kho kom zoo, qhov tshwm sim ntawm txoj cai ntawm qhov sib thooj ntawm cov xim ntawm cov xim tsis muaj, tsis pub tshem tawm qhov teeb meem ntawm kev kho. High-precision magnetic screen printing achieves tib cov nyhuv raws li kev xav, tab sis vim lub me me me me loj heev, cov kev cai rau cov phaj txiav txim siab yog siab kawg.
7. siab rhiab heev printing (6-7 xim)
Feem ntau, luam tawm los ntawm peb lub ntsiab xim (magenta, cyan, daj) thiab dub rau txoj kev sib txoos plaub-xim luam. Ntsuab ntxiv nrog cyan thiab daj superimposed. Txawm li cas los xij, hauv cov ntawv luam tawm, vim tus cwj mem (xws li cyan) luam tawm thawj zaug tsis qhuav, tom ntej xim (xws li daj) yog ntxim rau nws, kom tus cwj mem tsis tuaj yeem pauv mus rau hauv qab xim (tsis yog kev hloov) nws nyuaj rau restore tiag tiag li ntsuab.
Tsis tas li ntawd, thiaj li yuav nthuav cov xim kom khaus, peb xim liab, ntsuab, thiab xiav ntxiv rau plaub-xim xim luam tawm ua xya-xim luam ntawv. Tsis tas li ntawd, nyob rau ntawm plaub-xim xim txheej txheem, ob xim xim txiv kab ntxwv thiab ntsuab yog luam tawm ua cov xim luam-6-xim. Kev tu yuav tsum tau ua thaum ua tiav txoj kev luam ntawv no, thiab qhov xwm txheej ntawm txhua xim yuav tsum ua tib zoo xaiv. Nws yog ib qho tseem ceeb tshwj xeeb rau kev soj ntsuam cov xim 6-7 kom xaiv lub xeev lub xeev kom tsis txhob tshwm sim ntawm moiré (xws li cov ntxaij hlau sib nqus).
Tsis tas li ntawd, cov yas thooj siab siv los ua kom pom lub siab tshaj plaws ntawm cov xov tooj ntawm cov dot-tone, thiab siv ultra-teeb-resistant printing siv ultra-teeb-resistant inks thiab ultraviolet-absorbing inks yog xav tau ntawm kev xav tau super-light kuj nyob rau hauv prints rau sab nraum zoov siv. Tsis tas li ntawd, tsis ntev los no, siv cov ntaub ntawv tsis yog ntoo los xav txog tej teeb meem ntawm ib puag ncig, kom cov roj ntsha muaj roj (soybean inks), txhua yam ntawm cov luam ntawv, tag nrho cov ntawv tshwj xeeb yuav tsum muaj ntau theem tshuaj tshuab thiab qib txawj. tus yam ntxwv thiab cov teebmeem ntawm ntau yam tshwj xeeb cov ntawv luam tawm, qhov nqi ntawm cov teeb meem luam tawm, qhov sib txawv ntawm cov nqi, qhov txawv ntawm tus qauv zoo, thiab lwm yam. kom xaiv qhov yog.
