Muaj zog luam tau yooj yim
Peb txoj kev luam ntawv ntawm lithography, embossing thiab gravure tsuas tuaj yeem luam tawm ntawm cov tiaj tiaj. Kev tshuaj ntsuam luam ntawv tuaj yeem luam tawm tsis yog ntawm lub dav hlau nkaus xwb, tab sis kuj tseem nyob rau ntawm txheej txheej nrog cov npoo nkhaus, kheej kheej kheej kheej thiab lub ntsej muag convex nto. Ntawm qhov tod tes, kev tshuaj ntsuam luam ntawv tuaj yeem luam tawm tsis tsuas yog ntawm cov khoom nyuaj, tab sis kuj ntawm cov khoom muag, uas tsis txwv los ntawm kev ntxhib los mos ntawm cov substrate. Ib qho ntxiv, ntxiv rau kev luam ntawv ncaj qha, kev tshuaj ntsuam luam ntawv kuj tseem tuaj yeem luam tawm los ntawm kev luam ncaj qha raws li xav tau, uas yog, tshuaj ntsuam luam tawm ntawm gelatin lossis silica gel phaj ua ntej, thiab tom qab ntawd hloov mus rau txheej txheej. Yog li, nws tuaj yeem hais tau tias kev tshuaj ntsuam luam ntawv muaj qhov hloov pauv tau zoo thiab muaj ntau yam kev siv.
Muaj zog peb lub siab
Nrog kev ntxhib los mos zoo nkauj, txheej txheej tuab ntawm cov offset luam ntawv thiab embossing yog feem ntau 5 microns, gravure luam ntawv yog li 12 microns, tus lej txheej tuab ntawm flexographic (aniline) luam ntawv yog 10 microns, thiab tus lej txheej tuab ntawm npo luam ntawv deb tshaj saum toj txheej txheej tuab, feem ntau txog li 30 microns. Kev tshuaj ntsuam tuab rau cov ntawv tshwj xeeb luam tawm Circuit Court, nrog txheej txheej tuab txog li 1000 microns. Braille braille tau luam tawm nrog tus lej ua npuas dej, thiab tuab ntawm txheej txheej ua npuas dej tuaj yeem ncav cuag 1300 microns. Kev tshuaj ntsuam luam ntawv muaj txheej txheej tuab tuab, nplua nuj luam ntawv zoo thiab muaj zog peb lub siab, uas tsis tuaj yeem sib piv nrog lwm txoj hauv kev luam ntawv. Kev tshuaj ntsuam luam ntawv tuaj yeem tsis tsuas yog luam ntawv ib leeg, tab sis kuj tseem luam xim thiab luam ntawv xim.
Lub teeb ua haujlwm hnyav
Vim tias kev tshuaj ntsuam luam ntawv muaj cov yam ntxwv ntawm kev luam ntawv ploj, nws tuaj yeem siv ntau yam xim thiab txheej txheej, tsis tsuas yog slurry, nplaum thiab ntau yam xim, tab sis kuj muaj cov xim nrog cov ntxhib ntxhib. Ib qho ntxiv, tshuaj ntsuam luam ntawv tus lej tau yooj yim rau siv, piv txwv li, lub teeb xim tiv taus tuaj yeem tso ncaj qha rau hauv tus lej, uas yog lwm qhov tshwj xeeb ntawm kev tshuaj ntsuam luam ntawv. Cov khoom lag luam luam ntawv muaj qhov zoo ntawm qhov muaj zog tiv taus lub teeb. Qhov kev xyaum qhia pom tias raws li qhov ntau tshaj qhov ntsuas tau ntsuas tom qab ib qho embossing ntawm cov ntawv coated nrog cov xim dub, cov luam ntawv offset yog 1.4, luam ntawv embossing yog 1.6, thiab gravure luam ntawv yog 1.8, thaum lub siab tshaj plaws ntom ntau ntawm kev tshuaj ntsuam luam ntawv tuaj yeem ncav cuag 2.0. Yog li ntawd, lub teeb tsis kam ntawm cov khoom lag luam luam ntawv muaj zog dua li ntawm lwm yam khoom lag luam luam ntawv, uas yog qhov tsim nyog tshaj rau sab nraum zoov tshaj tawm thiab cov paib.
Loj cheeb tsam luam ntawv
Qhov loj tshaj plaws ntawm thaj chaw luam tawm los ntawm kev luam tawm dav dav, embossing thiab lwm txoj hauv kev luam ntawv yog daim ntawv loj. Yog tias nws dhau ntawm daim ntawv me me, nws raug txwv los ntawm cov cuab yeej siv tshuab. Kev tshuaj ntsuam luam ntawv tuaj yeem siv rau kev luam loj hauv cheeb tsam. Niaj hnub no, qhov ntau ntawm cov khoom lag luam luam ntawv tuaj yeem ncav cuag 3 meters × 4 meters lossis ntau dua.
Plaub lub ntsiab lus saum toj no tsis yog qhov sib txawv ntawm kev tshuaj ntsuam luam ntawv thiab lwm yam luam ntawv, tab sis kuj yog cov yam ntxwv thiab qhov zoo ntawm kev tshuaj ntsuam luam ntawv. Nkag siab cov yam ntxwv ntawm kev tshuaj ntsuam luam ntawv, hauv kev xaiv cov txheej txheem luam ntawv, peb tuaj yeem txhim kho qhov ua tau zoo thiab zam qhov tsis muaj zog, qhia qhov zoo ntawm kev tshuaj ntsuam luam ntawv, thiaj li ua tiav cov txiaj ntsig luam ntawv zoo dua.
