Nrog txoj kev loj hlob ntawm kev siv tshuab luam ntawv, cov ntawv luam tawm ntawv luam tawm ntawv tseem yog tsim los ntawm kev tsim cov khoom tsim tawm, txo cov nqi luam ntawv thiab nce nqi ntxiv. Qhov tshwm sim ntawm cov kab hauv hybrid yog nyob rau hauv txoj kab nrog txoj kev loj hlob zoo ntawm cov ntawv luam tawm cov ntawv luam tawm. Cov kua roj number case yog ib qho tseem ceeb ntawm cov khoom siv sib txuas ua ke hauv kev ua qauv ntawm UV printing inks, sib txuas cov kev ua haujlwm ntawm UV cov phom sij thiab cov pa roj carbon dioxide nyob rau hauv cov ntsiab lus ntawm kev ua tau zoo. Thaum tuav ceev cov yam ntxwv ntawm UV ciav hlau tawm, nws tsis tsuas yog daws qhov teeb meem ntawm gloss poob los ntawm daim ntawv thov ntawm UV varnish ntawm tus cwj pwm txwm, tab sis kuj zoo heev pab cov luam tawm piv nrog UV offset inks.
Yuav kom muaj kev sib tw ua lag luam, cov tuam txhab luam ntawv yuav tsum txhim kho cov khoom kom zoo, yog li ntawd lawv yuav tsum xaiv cov khoom siv thiab cov khoom siv hluav taws xob. Txij thaum UV inks muab tshwj xeeb tus nqi rau cov luam tawm, lawv siv yog nce. Hauv kev tshavpuam ntawm luam ntawv, UV offset luam ntawv tau dhau los ua ib qho tseem ceeb rau cov phau ntawv npog, kev tshaj tawm txog kev tshaj tawm, thiab kho kom zoo nkauj. Vim hais tias ntawm qhov zoo nkauj zoo ntawm UV number case, nws tsis muaj cov tshuaj tsis haum xeeb thiab kev kho sai sai, thiab nyiam cov neeg. Daim ntawv thov UV ua haujlwm hauv offset luam ntawv tau qhia tias kev loj hlob zoo.
Ua ntej, daim ntawv thov txheej txheem ntawm UV number case
Lub ntsiab Cheebtsam ntawm UV number case muaj xws li cov organic pigment, prepolymerable photolymerable, monoensens monomer, photopolymerization initiator, thiab cov zoo li.
UV thom daws teebmeem qhov teebmeem hauv kev luam tawm nrog lawv txoj kev kom qhuav. Nws cov ntsiab lus qhuav yog ua kom muaj yees duab ntawm tus cwj pwm ntawm ultraviolet radiation rau tus cwj mem, uas ua kom tiav lub hom phiaj ntawm kev kho lub cwj mem. UV inks muaj cov nram qab no ob lub ntsiab kev tshuaj lom neeg thaum lub caij ziab khaub ncaws.
1. Photochemical cov tshuaj tiv thaiv: Lub photopolymerization initiator muaj nyob rau hauv ib tug number case undergoes ib tug reactcharged nyob rau hauv ultraviolet irradiation los ua ib tug radical.
2. Cov tshuaj tiv thaiv: Qhov dawb radical polfunctional prepolymer, polyfunctional prepolymer, polyfunctional crosslinking tus neeg saib xyuas thiab reactive diluent nyob rau hauv cov number case yog chained los ntawm cov tshuaj tiv thaiv photchemical mus ua dawb radicals peev xwm ntawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no yog sib txuas ua ke rau ib leeg los tsim ib cov khoom siv luam yeeb uas muaj cov qauv peb sab - ib zaj duab xis xoom xim.
Yog li, qhov ziab ntawm UV number case feem ntau yog nyob ntawm cov ziab khoom ntawm cov luam ntawm photocuring, xwv li tias tus number case muaj qhov sib txawv ziab khoom nyob rau hauv cov xwm txheej tau txais lub teeb thiab tsis muaj teeb meem ntawm lub teeb, uas yog, tus number case tsis tau lub teeb thaum lub sij hawm luam ntawv, thiab tswj cov khoom qub ruaj khov, thiab muaj cov khoom zoo. Kev luam xeev; tom qab luam ntawv, nws yog irradiated los ntawm ultraviolet lub teeb thiab qhuav sai sai, uas tuaj yeem ntsib cov haujlwm tom qab, ua kom zoo tshaj qhov qub, thiab ua kom zoo dua ntxiv ntawm tus lej ntawm tus lej ziab.
Qhov thib ob, qhov zoo ntawm UV number case
1. Lub cev tsis muaj zog: Feem ntau cov tshuaj UV muaj tsawg tus los yog tsis muaj cov organic solvent, tsis muaj teeb meem hnyav thiab puas tsuaj rau cov ntawv luam tawm, thiab tsis muaj cov pa phem rau tib neeg lub cev thiab qhov chaw nyob.
2. Kev tsim nyog rau cov ntawv tsis substrates: tuaj yeem luam tawm ntawm cov khoom qub, thiab tseem tuaj yeem luam tawm rau cov ntaub ntawv tsis yog khoom siv xws li cov yeeb yaj kiab, cov ntawv hluav taws xob, hlau lossis yas.
3. Kev kho rau kev kho mob sai tom qab: nws tuaj yeem kho sai sai tom qab raug hluav taws xob los ntawm ultraviolet light.
4. Tus nqi ntawm tus cwj pwm uas siv tau yog tsawg: Vim tsis muaj tus cwj pwm UV, tsis yog tus cwj pwm uas siv rau ntawm 1/3 txog 1/2 ntawm tus cwj mem ib txwm muaj peev xwm tau txais qhov kev xav tau.
5. Muaj peev xwm ua kom muaj xim sib txawv: Kho lub viscosity, xim tone thiab qhov ci ntawm tus cwj pwm ntawm cov xim yuav muaj xim nplua nuj. Cia li sib tov ob los yog ntau cov xim yooj yim kom tau ntau yam xim.
6. Kev yoojyim yog kev yoojyim tswj: pigments lossis pigments tuaj yeem raug ntxiv rau lub hauv paus mus txuas ntxiv kom tiav qhov kev ntshaw raws li tus qauv ntsuas.
7. UV number case tuaj yeem ua haujlwm nyob rau hauv tshwj xeeb luam ntawv xws li dej khov, tawg, txhaws thiab pob tw.
Thib peb, UV offset luam ntawv
Offset luam ntawv yog ib qho kev lagluam rau kev lagluam, tabsis cov tshuab luam ntawv tseem niaj hnub pib. UV tshuab tau zoo tuaj yeem tsim cov khoom kom zoo dua qub, ua kom muaj zog dua qub thiab txhim kho qhov chaw. Yog li, daim ntawv thov UV hauv offset printing tseem yog loj heev.
UV number case yog siv rau hauv kev lag luam luam tawm. Cov teeb meem luam tawm tau zoo lawm thaum nws ncav cuag lub tsho, uas yuav tiv thaiv tau cov hmoov txau, uas zoo rau kev ntxuav ntawm lub chaw luam ntawv, tiv thaiv kev noj qab haus huv ntawm tus neeg teb xov tooj, thiab tiv thaiv teeb meem los ntawm hmoov txheej. Piv txwv, qhov teebmeem glazing thiab zaj duab xis mulching yuav ua tiav. Txhim kho qhov chaw ua hauj lwm, ua kom cov khoom siv tau zoo dua thiab muab sij hawm luv luv.
UV number case tom qab kho tau los ntawm UV teeb ci. Nws tsis crust nyob rau hauv lub laub tank ua ntej nws yog irradiated, thiab nws yuav tsis qhuav tawm ntawm qhov chaw thiab daim hlau ntawm lub tshuab luam ntawv. Cov cwj pwm no tuaj yeem tiv thaiv qhov teeb meem ntawm tus ntiv tes xoo thiab daws cov sij hawm poob ntawm lub tshuab luam ntawv. Cov kev txhawj xeeb ntawm lub sij hawm txo cov khib nyiab ntawm tus cwj pwm.
UV offset printing inks yuav tsum muaj cov luam ntawv, cov ntawv lo thiab cov pam vov. Vim tias UV phom muaj cov kabmob reactive monomer thiab cov thaij duab, lawv tuaj yeem ua rau cov dots nyob rau hauv lub plab npog zoo tib yam PS thiab txo qhov kev lag luam ntawm cov ntawv luam tawm. Yog li no, UV offset luam ntawv yuav tsum xaiv qhov tshwj xeeb UV offset PS version. Cov neeg ua hauj lwm nrog cov neeg ua hauj lwm los ntawm cov neeg ua hauj lwm los ntawm kev lag luam, thiab cov neeg ua hauj lwm. Thaum pib ntawm lub tshuab, cov tshuab monomer nyob rau hauv cov cwj mem xaj yog txo los ntawm lub nqus dej ntawm qhov kev sib txuas ntawm monomer no. Tus lej number case txuas txuas tsis txaus, thiab thaum UV teeb tuaj yeem kho thiab kho, tus cwj pwm xuv xim tsis kho kom zoo, thiab cov ntawv luam tawm tsis ua rau kev sib txhuam. Qhov thib ob, qhov tsis ua haujlwm ntawm cov nplaum lo thiab daim pam, tus kabmob reactive thom khwm hauv tus cwj mem tawm UV yuav ua rau cov nplaum nplaum nplaum thiab daim pam, kom tsis txhob ua txhua zaus. Yog li, UV offset luam ntawv yuav tsum siv tus UV lo hnab lo thiab UV daim ntawv tshwj xeeb.
Tam sim no, feem ntau ntawm cov tuam txhab luam ntawv 'UV offset luam ntawv yog qhov muag xim xim, vim li no cov kev hloov ntawm cov xim sib txawv kuj yog txawv ntawm cov kev kawm luam tawm. Nyob rau hauv UV offset colour sequence arrangement, tsuas yog los ntawm ob qho ntawm kev ziab thiab cov khoom ntawm cov khoom luam tawm: 1 ntxiv rau lub voj voog raws li qhov nyuaj ntawm kev kho ntawm loj los me me yuav tsum dawb, dub, xiav, daj, magenta. Qhov no yog vim hais tias hauv cov xim sib txawv nyias muaj nyias UV kev sib kis. Rau cov UV photons, magenta transmittance yog 50% rau 60%, daj yog 20% mus rau 30%, ntsuab yog 8% mus rau 20%, cov dub yog 12%, thiab tus cwj mem dawb muaj qhov qis tshaj plaws. Vim li no, hauv kev luam tawm, UV number case printing Cov xim raws caij nyoog yuav tsum W, BK, C, Y, M.2 ntxiv rau lub voj voos. Thaum qhov muag xim xim, luam tawm me me los sis kab ntawv kab ntawv yuav tsum luam ua ntej. Yuav tsum muab tus lej ntxoo nrog cov xim sib tsoo thiab qhov chaw me me coj los tso ua ntej, thiab yuav tsum muab tus number case loj loj tso rau. Thaum kawg no, qhov no yuav zam tau khawb thaj chaw loj ntawm cov luam ntawv, cuam tshuam cov tsos ntawm cov khoom luam tawm, thiab tuaj yeem txhim kho cov ntawv sau npe.
Rau tej offset thiab UV offset printing, tswj number case tshuav yog qhov tseem ceeb. Cov tshuaj siv dampening siv hauv UV cov ntawv luam tawm yog tib yam li cov luam tawm tsis zoo tib yam, yog li txoj cai ntawm cov dej tsawg thiab tsawg dua tus cwj pwm kuj tseem yuav tsum tau siv. Cov pH ntawm cov dampening kua yuav tsum nyob nruab nrab ntawm 5.5 thiab 6.0, thaum cov khoom feem ntau tswj ntawm 5.0 thiab 6.5.
Qhov plaub, qhov teeb meem ntawm UV luam tawm
1. Duav kom huv si yog qhov nyuaj, koj yuav tsum muaj dej kub tshwj xeeb, ntxuav tu.
2. UV number case cia sijhawm tsis ntev. Tam sim no, lub txee lub neej ntawm UV inks tsis ntev, vim tias UV cov phev mas nws yuav nkag mus rau qhov qub thiab deterioration.
3. UV cov khoom tsuas yog kho tau raws li kev ncaj qha UV irradiation, tab sis cov khoom tua cov khoom kim kim kim thiab cov peev hauv kev luam ntawv yog loj, uas nce nqi luam ntawv.
4. UV lub teeb txeem cov thicker thiab pigment-containing coatings, uas yog ib qho nyuaj ua rau kom muaj tus cwj pwm tsis kho thiab kho tsis zoo.
5. Tus nqi ntawm cov ntaub ntawv raw khoom yog siab heev thiab tus nqi ntawm cov ntawv luam tawm tau nce.
6. Tsis zoo nkauj. Feem ntau, piv rau cov khoom ua ke, UV inks muaj pluag adhesion rau qee cov ntaub ntawv, nrog rau cov nplooj ntawv txhuam thiab txhuas txhuas, thiab tuaj yeem hloov kho kom tshem tawm qee qhov teeb meem ntawm cov neeg pluag adhesion.
Nyob rau hauv luv luv, UV offset luam txheej txheem yog nyuaj rau master. Nws yuav tsum ua tib zoo saib hauv kev ua haujlwm, ua tib zoo ua ke, ua ke nrog kev xav thiab kev xyaum los daws cov teeb meem, thiab muab piv nrog cov kev los daws cov teeb meem nquag muaj teeb meem luam tawm, nrhiav kev sib sim thiab kev sib txawv. Raws li txoj kev coj ntawm txoj kev loj hlob ntawm tus number case, UV npauj npog embodies li ntawm cov tib neeg kev ras txog. UV npauj npaug tau los ua tus cag loj loj hlob ntsuab nyob rau hauv lub ntiaj teb. Nws yog txoj kev loj hlob ntawm kev luam ntawv rau yav tom ntej. Nws yuav hloov cov lej dej uas nyob hauv tej cheeb tsam thiab ua tus cim xeeb tshaj plaws hauv lub cev thiab ruaj khov.
