Nyob rau hauv multi-colour printing ntawm offset daim ntawv, thiaj li yuav xyuas kom zoo ntawm cov teeb meem luam tawm thiab ua tau raws li cov kev cai ntawm cov neeg muas zaub, peb yuav tsum tswj tag nrho cov yam. Kuv xav tias kev ua kom pom tseeb yuav tsum ua raws li cov hauv qab no.
1. Kev tswj ntawm phaj kev zoo
(1) Thaum luam ntawv, me ntsis nce qhov kev raug mob tiag tiag kom cov dots ntawm lub phaj yog me ntsis me dua cov dots ntawm cov yeeb yaj kiab kom them nyiaj ntxiv rau qhov sib ntxiv ntawm lub siab thaum lub sij hawm luam ntawv.
(2) Thaum lub txheej txheem ci, cov ntawv phom sij yuav ua raws li kev loj hlob thiab kev mob nkeeg thaum lub caij txias ntawm txias los kub. Yog li, thiaj li ua kom tiav meej tshaj, kev ci feem ntau tsis pom zoo thaum ua ntau hom ntawv luam tawm.
(3) Lub tsev kawm ntawv tsab ntawv yuav tsum paub zoo thiab muaj tseeb, txo cov pov thawj ntawm cov pov thawj, thiab tsis txhob ua txhaum cov ntawv tshaj tawm ntawm cov khoom deev.
2. Kev tswj siab
(1) Txij li cov nplais ntawm cov ntawv offset yog ntxhib, tus number case absorbing kev ua tau zoo. Yog li, thiaj li yuav ua rau cov ntawv luam tawm tuab thiab cov dots yog qhov tseeb, lub tshuab luam ntawv yuav tsum muaj qhov tsim nyog kom ntev thaum luam ntawv.
(2) Lub siab ntawm cov taub dej thiab tus cuav quav rau tus kheej yuav tsum tsim nyog thaum tswj kev hloov dej zoo thiab muab ntim cov ntawv hloov.
3. Xaiv cov khoom siv luam ntawv
(1) Ntawv. Nyob rau hauv ntau lub xim txheej txheem, cov ntawv uas muaj qhov zoo sizing degree thiab cov ntawv luam tawm yuav tsum raug xaiv kom tsis txhob muaj qhov tshwm sim ntawm kev rub tawm thiab xa mus ua hmoov. Nyob rau tib lub sijhawm, xyuam xim rau tej yam ntawm daim ntawv pH ntawm kev luam zoo. Daim ntawv yuav tsum tau muab dai ua ntej luam ntawv.
(2) Ink. Tus cwj pwm sai thiab zuaj qaub cwj mem yog ib qho kua osmotic drying hom, uas yuav zam tau qhov tshwm sim ntawm hmoov, pas, nplaum, thiab rub tus cwj mem hlau hom, thiab tsim nyog rau luam ntawv on offset ntawv, yog li nws pom zoo rau siv tus cwj pwm kom sai thiab zuaj qes hom.
(3) Pam tuag. Yuav kom ntseeg tau tias cov dots tuaj yeem txum tim rov qab zoo dua qub, lub hnab yuav zoo tuaj, thiab yuav tsum tau siv daim pam daim thaiv lub thawv.
4. Kev tswj cov ntawv luam tawm
(1) Cov tshuaj pH ntawm dampening solution yog tswj ntawm 5.5 mus rau 6.5. Yog tias cov tshuaj tsis haum pH tsis tswj, nws yuav ua rau lub plab thiab luam zoo.
(2) Siv lub nrig ntawm lub tshuab luam ntawv thaum lub sij hawm luam tawm, thiab tswj kom muaj cov lej ntawm cov cwj mem thiab dej kom ncav qhov zoo tshaj plaws ntawm lub "printing number".
(3) Tswj kev ntsuas kub thiab av noo ntawm qhov kev cob qhia. Hauv cov txheej txheem luam ntawv ntawm cov ntawv pov thawj, thaum lub voj voos loj loj, cov pob txha, rub, poob hmoov, thiab lwm yam yog yooj yim generated, thiab thaum twg cov av noo me me, hluav taws xob zoo yog yooj yim generated. Yuav kom ua tiav qhov zoo tshaj plaws luam ntawv, qhov ntsuas kub ntawm qhov rhiav yog tswj li ntawm 22 mus rau 25 ° C, thiab cov av pwm ntawm 55% txog 65%.
