Kev tshuaj xyuas cov teeb meem tshwm sim hauv UV offset luam ntawv

Nrog rau daim ntawv thov ntawm cov ntaub ntawv tsis-absorbable printing xws li kub thiab nyiaj cardboard thiab laser hloov daim ntawv nyob rau hauv cov luam yeeb tej pob khoom, UV offset printing tshuab kuj nce lug siv nyob rau hauv luam yeeb pob.Txawm li cas los xij, kev tswj hwm ntawm UV offset luam ntawv txheej txheem kuj tseem nyuaj, thiab ntau yam teeb meem zoo tau yooj yim tshwm sim hauv cov txheej txheem ntau lawm.

Ink roller glaze
Nyob rau hauv tus txheej txheem ntawm UV offset luam ntawv, lub glossy glaze tshwm sim yuav tshwm sim thaum tus number case roller khiav ntawm kev kub ceev rau lub sij hawm ntev, ua rau inking tsis zoo, thiab qhov sib npaug ntawm tus number case thiab dej yog qhov nyuaj rau lav.
Nws tau pom nyob rau hauv qhov tseeb ntau lawm tias ib pawg ntawm cov cwj mem tshiab yuav tsis tsim cov ci ci hauv thawj lub hlis ntawm kev siv, yog li immersing tus number case rollers hauv tus number case rollers txo qhov muab tshuaj txhuam rau 4 mus rau 5 teev txhua lub hli tuaj yeem rov qab ua haujlwm ntawm tus number case rollers, yog li txo cov tiam ntawm glossy glaze ntawm tus number case rollers.

Ink roller expansion
Raws li peb txhua tus paub, UV number case yog corrosive heev, yog li tus number case cov menyuam ncig los ntawm UV offset number case yuav kuj nthuav.
Thaum lub tshuab luam ntawv nthuav dav, cov kev kho mob tsim nyog yuav tsum tau ua raws sijhawm kom tsis txhob muaj qhov tshwm sim tsis zoo.Qhov tseem ceeb tshaj plaws yog los tiv thaiv kev nthuav dav los ntawm kev ua rau lub siab ntau dhau ntawm tus cwj mem rau cov menyuam, txwv tsis pub nws yuav ua rau npuas, gel tawg thiab lwm yam tshwm sim, thiab tseem ua rau muaj kev puas tsuaj rau UV offset luam ntawv cov cuab yeej loj.

Kev luam ntawv cuav
Kev luam ntawv tsis raug hauv UV offset luam ntawv ntawm cov ntim luam yeeb tuaj yeem muab faib ua ob hom hauv qab no.
(1) UV curing xim lawj luam ntawv tsis yog khoom.
Nyob rau hauv cov ntaub ntawv no, cov xim sib lawv liag yuav tsum tau teem kom tsim nyog, thiab UV teeb ntawm cov xim decks yuav tsum tau zam kom deb li deb li sai tau.Feem ntau, cov xim dawb txheej ntawm thawj luam ntawv yog thickened thiab UV curing yog nqa tawm;Thaum luam ntawv dawb number case rau zaum ob, cov number case txheej yuav thinned yam tsis muaj UV curing.Tom qab overprinting nrog lwm cov xim decks, cov nyhuv tiaj tus kuj tuaj yeem ua tiav.
(2) Qhov loj ntawm thaj chaw luam ntawv tsis muaj tseeb.
Muaj ntau yam cuam tshuam rau thaj tsam loj ntawm kev luam ntawv.Txhawm rau kom tsis txhob muaj thaj tsam loj ntawm kev luam ntawv, thawj zaug xyuas seb tus number case roller siab puas yog los xyuas kom meej tias tus number case roller tsis muaj glaze;Paub meej tias cov txheej txheem tsis raug ntawm qhov kev daws teeb meem yog qhov tseeb;Qhov saum npoo ntawm daim pam yuav tsum tsis muaj av, pinholes, thiab lwm yam .. Tsis tas li ntawd, qhov kev ntsuam xyuas tau ua pov thawj tias huab cua compression ntawm ib pab pawg tom qab loj cheeb tsam luam ntawv yuav muaj kev cuam tshuam tam sim ntawm kev txhim kho lub tiaj tiaj ntawm thaj chaw loj luam ntawv.

Ink rov qab rub
Hauv UV offset luam ntawv, number case rov qab rub tawm yog qhov ua tsis tau zoo, feem ntau vim tias UV offset luam ntawv number case tsis kho tag nrho tom qab UV irradiation, thiab nws tsis ruaj khov rau hauv substrate.Raws li cov txiaj ntsig ntawm kev luam ntawv siab ntawm cov xim tom ntej, tus number case yog rub thiab daig rau daim pam ntawm lwm cov xim decks.
Thaum tus number case rov qab rub tawm, feem ntau nws tuaj yeem daws tau los ntawm kev txo cov dej ntawm UV curing xim pab pawg, ua kom cov dej ntsiab lus ntawm tus cwj mem kos xim pab pawg, thiab txo cov kev luam ntawv siab ntawm tus number case drawing xim pawg;Yog tias qhov teeb meem tseem tsis tuaj yeem daws tau, kho nws los ntawm UV
Qhov teeb meem no tuaj yeem txhim kho los ntawm kev ntxiv tus nqi tsim nyog ntawm tus neeg sawv cev tensile rau tus cwj mem ntawm cov xim xim.Tsis tas li ntawd, kev laus ntawm daim pam roj hmab kuj yog ib qho laj thawj tseem ceeb rau tus cwj mem rov qab rub tshwm sim.

Kev luam ntawv barcode tsis zoo
Rau UV offset luam ntawv ntawm cov ntim luam yeeb, qhov zoo ntawm barcode luam ntawv yog qhov tseem ceeb qhia.Ntxiv mus, vim muaj zog xav txog ntawm kub thiab nyiaj cardboard rau lub teeb, nws yog ib qho yooj yim mus ua kom lub bar code nrhiav kom tsis ruaj tsis khov los yog txawm substandard.Feem ntau, muaj ob qhov xwm txheej tseem ceeb thaum UV offset barcode ntawm cov luam yeeb pob ua tsis tau raws li tus qauv: defect degree thiab decoding degree.Thaum qhov kev kawm tsis raug tsis yog raws li tus qauv, xyuas seb cov ntawv luam ntawv dawb puas tiaj tus thiab seb daim ntawv puas tau them tag nrho;Thaum lub decodeability tsis yog raws li tus qauv, xyuas cov number case emulsification ntawm barcode printing xim lawj thiab seb lub barcode puas muaj ghosting.
UV offset luam ntawv inks nrog cov xim sib txawv muaj qhov sib txawv rau UV.Feem ntau, UV yog yooj yim dua rau nkag mus rau daj thiab magenta UV offset printing inks, tab sis nws yog ib qho nyuaj rau nkag mus rau cyan thiab dub UV offset printing inks, tshwj xeeb tshaj yog dub UV offset printing inks.Yog li ntawd, nyob rau hauv UV offset printing, yog hais tias lub thickness ntawm dub UV offset number case yog nce los txhim kho cov nyhuv luam ntawv ntawm barcode, nws yuav ua rau tsis zoo ziab ntawm tus number case, tsis zoo adhesion ntawm tus number case txheej, yooj yim rau poob, thiab txawm phem. adhesion.
Yog li ntawd, tshwj xeeb yuav tsum tau them nyiaj rau lub thickness ntawm dub number case txheej nyob rau hauv UV offset printing los tiv thaiv barcode los ntawm sticking.

Cia ntawm UV offset luam ntawv number case
UV offset luam ntawv number case yuav tsum muab cia rau hauv qhov chaw tsaus hauv qab 25 ℃.Yog tias khaws cia ntawm qhov kub siab, UV offset luam ntawv number case yuav solidify thiab harden.Tshwj xeeb tshaj yog, UV offset kub thiab nyiaj number case yog qhov yooj yim rau solidification thiab tsis zoo gloss dua li UV offset number case, yog li nws yog qhov zoo dua tsis txhob khaws nws ntev.
Hauv luv luv, UV offset luam ntawv txheej txheem yog qhov nyuaj rau tus tswv.Cov kws tshaj lij ntawm cov luam yeeb pob luam ntawv lag luam yuav tsum ua tib zoo saib thiab sau cov ntsiab lus hauv kev luam ntawv.Raws li kev paub txog qee qhov kev paub theoretical tsim nyog, kev sib txuas cov kev xav thiab kev paub dhau los yog qhov tsim nyog rau kev daws cov teeb meem tshwm sim hauv UV offset luam ntawv.
