Kev siv zog yuav tsum ua kom txo cov hmoov av siv los luam tawm.
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Hauv kev luam ntawv, cov plua plav (dusting) siv los tiv thaiv kom tsis txhob haus luam yeeb nyob tom qab ntawm qhov khoom. Niaj hnub no, ntau tshaj li cov tshuab luam ntawv tau muab tshem tawm cov hmoov tsuag txau, thiab siv peb hom kev ziab khaub ncaws, xws li: ob lub teeb ntawm sab qaum thiab ib txheej ntawm ultraviolet. Tam sim no, feem ntau ntawm peb cov khoom siv hluav taws xob feem ntau kuj yog cov tshuaj txau cov hmoov av los yog tsuas yog cov hmoov tsuag tsuag xwb.
Feem ntau thaum lub plhaub taum plig yog tuab thiab qhov chaw tsaus nti loj zus, tus neeg luam ntawv yeej ib txwm xav muab cov hmoov ntau dua, kom cov khoom yuav tsis khawb vim qhov nraub qaum yog qias neeg, tab sis feem ntau cov hmoov yog tsis quav ntsej . Tej zaum yuav me me qhov teeb meem no. Nyob rau hauv qhov tseeb, ntau dhau hmoov yuav coj ntau ntawm kev raug mob.
1. Tus nqi ntawm hmoov yog loj heev. Thaum sab pem hauv ntej thiab sab nraum qab, cov hmoov ntawm sab pem hauv ntej yuav tau ncaj qha mus cuam tshuam. Nyob rau hauv loj heev zaum, nws yog ib qhov tsim nyog los ntxuav lub pam txhua daim ntawv ob peb nplooj. Cov khoom yuav yog li ntawd tsis ruaj tsis khov xim, cuam tshuam ob qho tib si zoo thiab tawm los.
2. Tus nqi ntawm hmoov yog loj heev, cuam tshuam rau lub gloss ntawm cov khoom. Thaum luam ntawv qee yam khoom siv siab, tus neeg teb xov tooj yeej xav kom muaj tus lej tsawg dua. Cov ntawv luam tawm yog ob qho tib si ci thiab kaj, thiab tib lub sij hawm nce tus nqi ntawm hmoov kom thiaj li tsis txhob smudging. Cov hmoov yog absorbed los ntawm tus number case nyob ntawm tus number case txheej uas tsis tau qhuav, thiab ib cov huab cua yog ua rau xim, thiab gloss ntawm qhov khoom yog li no.
3. Cov hmoov hmoov ntau dhau lawm, thiab hnav cov khoom siv thiab khoom siv yog qhov loj. Nyob rau hauv cov khoom, thaum txau cov hmoov mus rau cov khoom, ntau npaum li cas hmoov yog ya rau lub tshuab xa khoom, gripper thiab cov menyuam. Txawm hais tias muaj kev tu lub sijhawm txhua lub lim tiam, nws yuav tsis muaj peev xwm tu tau tag nrho cov hmoov av. Dhau li ntawm lub sijhawm, nws yuav tsis tshua tau nce thiab tsim kua muag ntawm lub tshuab.
4. Tus nqi ntawm cov hmoov yog loj heev, uas yuav muaj kev cuam tshuam rau kev noj qab haus huv ntawm tus neeg teb xov tooj. Txawm hais tias tus neeg lag luam hais tias cov hmoov tsis muaj mob rau tib neeg lub cev, tus neeg khiav dej num yuav nyob hauv qhov kev cob qhia me me txhua hnub, thiab lub ntsws tsis paub tias hmoov av ntau npaum li cas.
5. Yog tias cov hmoov ntau dhau lawm, nws yuav cuam tshuam rau cov txheej txheem ntawm cov txheej txheem tom qab, xws li teeb lub teeb.
Vim li no, peb yuav tsum them nyiaj txaus rau cov hmoov siv, thiab muab tshuaj pleev kom tsawg dua li qhov ua tau kom muaj lub hom phiaj ntawm kev tswj cov ntaiv rov qab. Muaj ntau ntau yam uas ua rau rov qab smudging nyob rau hauv ntau lawm, thiab lub ntsiab yog yuav ua li cas tswj tau nws.
1. Nyuaj tswj tus nqi ceev. Tus nqi ntawm txhua qhov xim muaj xim yog tau los ntawm kev pov thawj, thiab tus nqi K, cov txiaj ntsig kev nce nqi, thiab qhov xim ntawm tus number case xim coj los ua kom tau qhov zoo tshaj plaws. Hauv qhov kev txiav txim siab, qhov zoo tshaj plaws tus nqi (ntom) tau txais los ntawm hom no kuj yog qhov zoo tshaj plaws ntawm daim ntawv los tiv thaiv tus number case. Piv txwv, qhov zoo tshaj plaws qhov tseem ceeb peb tau txais nrog 128 gram ntawm Japanese coated ntawv yog daj 1.05, liab 1.35, xiav 1.45, dub 1.70. Peb tuaj yeem khaws cov ntaub ntawv no rau kev luam tawm hauv kev tsim khoom. Raws li ib txwm muaj, nws yuav tsis tuaj yeem tau qias neeg. Ntxiv ib qho me me ntawm cov plua plav yuav ntxiv kev tuav pov hwm. Txawm li cas los xij, qhov ntom yog qhov siab tshaj, thiab txawm tias tus lej hauv plag yog tsis tuab, nws tseem yuav qias neeg. Piv txwv, piv nrog 100% overprinting ntawm daj thiab magenta thiab cov overprinting ntawm plaub xim, nws yog tseeb tias 100% number case txheej ntawm txhua daj thiab magenta tsis tuab. Yog hais tias tus nqi xim daj yog nce los ntawm 1.30 los yog ntau dua, qhov nqi ntawm magenta qhov ntau ntxiv yog nce los ntawm 1.50 los yog ntau dua. Tshaj tawm tus nqi tseem ceeb ntawm daim ntawv muaj peev xwm los tiv thaiv tus cwj mem, qhov khoom yog ib qho yooj yim heev rau smear nyob tom qab.
2. Qhov laj thawj yog vim li cas peb siv cov hmoov yog vim qhov chaw tsaus nti ntawm qhov khoom loj thiab lub plhaub txheej yog tuab. Hauv cov ntaub ntawv xws li cov ntawv sau, peb yuav tsum siv cov phaj-txiav txim siab los txo cov ink-adjusted ink layer los ntawm kev siv cov phaj-kev ua kom ntau li ntau tau. Tus lej number case yog tswj li ntawm 235% thiab 270%, uas yog 125% mus 90% tsawg dua tus lej ntawm tus qauv ntawm tus qauv, kom qhov yuav tsum tau ceev ntawm qhov kev sib txawv tsaus nti, thiab cov nrab ntawm qhov tsaus ntuj tsis muaj teeb meem los ntawm ntau npaum li cas ntawm tus nqi txo qis dua. Kho cov qib. Raws li cov ntaub ntawv tseem ceeb, tagnrho cov cim ntim ntawm 235% thiab tus lej ntsuas tag nrho ntawm 360% txo tus lej number case los ntawm 125% thiab cov qhov tseem ceeb qhia tau zoo heev. Thaum twg tus nqi tsaus nti ntawm tus lej tag nrho yog 235%, cov luam ntawv tuaj yeem tiv thaiv sab nraud qis tsis txau cov hmoov los yog ib qho me me ntawm hmoov.
3. Cov ntawv pov thawj yog cov qhab nia tus neeg muaj ntawv pov thawj thiab lub hauv paus rau kev luam ntawv. Yog tias cov ntawv luam tawm thiab cov qauv no loj dhau, tus qhua tuaj yeem yuav tsis lees txais nws yam tsis muaj kev coj noj coj ua. Cov lus nug no yog seb cov pov thawj qhia qhov tseem ceeb. Piv txwv, tus lej ntawm tus lej tsis tshua yog tsis zoo li ntawd, thiab tus nqi ntawm tus cwj mem zis yog xav ua kom tau raws li cov neeg siv tau txaus siab thaum muaj ntawv pov thawj lossis kos npe. Qhov no yuav ua rau qhov hluav taws xob los nthuav loj heev. Qhov nthuav ntawm lub qhov hluav taws xob yuav kis tau los ntawm qhov chaw mus rau qhov chaw. Tus number case nyob rau hauv qhov chaw yuav pom tseeb tshaj cov nqi ntawm daim ntawv, yog li nws yog qhov nyuaj kom tsis txhob smudging yam tsis muaj tus nqi ntawm cov hmoov.
4. Ink emulsification yuav ua rau lub sij hawm ziab ntawm qhov khoom. Thaum twg tus number case muaj qee cov kua qaub kua qaub, nws yuav ua rau lub sij hawm ntawm oxidizing thiab conjunctiva rau ntawm lub pob zeb, uas ua rau qeeb qis thiab yooj yim ua rau rov qab txaj muag. Muaj ntau ntau yam uas ua rau muaj kev xiam hoob qhab loj heev, tab sis qhov tseem ceeb tshaj plaws yog dej, thiab tib lub sijhawm tswj tus nqi ntawm tus cwj mem. Yam tsawg kawg ntawm tus cwj pwm thiab qhov tsawg kawg nkaus ntawm cov dej yuav tsum raug siv thaum muaj qee qhov sib npaug, uas yog qhov zoo tshaj los tswj qhov loj heev emulsification ntawm tus cwj mem.
5. Lub tshuab luam ntawv nyuaj heev, kom tsis txhob muab tus lej cim hloov tsis tau. Tus cwj mem muab xa mus rau daim ntawv tsis tuaj yeem sib raug zoo rau daim ntawv. Lub cim naj npawb tsuas ntab rau saum npoo ntawm ntawv, uas tsis muaj zog thiab tuaj yeem ua rau rov qab ua qias neeg. Yog li ntawd, nyob rau hauv ntau qhov kev tshaj tawm, cov tshuab luam ntawv yuav tsum tau nce kom ntau.
Hauv cov ntsiab lus, peb yuav tsum tau siv cov hmoov av ntau dua los yog tsis muaj dusting los tswj cov nrob qaum. Peb yuav tsum nqa cov kev tshawb fawb loj los ntawm kev ua thawj, tsim cov txheej txheem tsim kho, thiab ua tus thawj phaj tsim rau luam tawm los ntawm phaj ua. Txuj ci pov thawj. Hauv kev luam, nws yuav tsum tau ua raws li cov ntaub ntawv ua lag luam, tswj tus nqi ceev, siab thiab number case tshuav ntawm txhua xim, tuav ib cov luam ntawv qis, tsim nyog ua kom nce qee cov roj qhuav, thiab txo qhov siab ntawm cov khoom tiav.
