Offset luam ntawv
Offset luam ntawv, tseem hu ua offset lithography, yog ib txoj hauv kev ntawm kev luam ntawv loj uas cov duab ntawm cov phaj hlau raug xa mus (offset) rau cov pam vov lossis cov chais thiab tom qab ntawd mus rau cov ntawv luam tawm.Cov ntawv luam tawm, feem ntau yog daim ntawv, tsis tuaj yeem nkag ncaj qha nrog cov phiaj hlau.
UV luam ntawv
UV luam ntawv yog ib qho yooj yim tshaj plaws thiab zoo siab tshaj plaws cov txheej txheem luam tawm ncaj qha rau cov khoom uas tau tsim, thiab nws cov kev siv yuav luag tsis muaj kev txwv.UV luam ntawv yog ib daim ntawv tshwj xeeb ntawmluam ntawv digitaluas cuam tshuam nrog kev siv ultraviolet (UV) lub teeb los kho lossis qhuav UV number case yuav luag sai li sai tau thaum nws tau thov rau cov txheej txheem npaj.Lub substrate tuaj yeem suav nrog ntawv thiab lwm yam khoom siv uas lub tshuab luam ntawv tuaj yeem txais.Qhov no tuaj yeem ua npuas ncauj, aluminium, lossis acrylic.Raws li UV number case raug xa mus rau substrate, tshwj xeeb ultraviolet teeb nyob rau hauv lub tshuab luam ntawv yog tam sim ntawd siv rau cov khoom nyob rau sab saum toj ntawm tus number case, ziab nws thiab adhering rau lub substrate.
UV inks qhuav los ntawm cov txheej txheem photomechanical.Cov inks raug rau ultra-violet teeb thaum lawv luam tawm, tam sim ntawd tig los ntawm cov kua mus rau ib qho khoom nrog me ntsis evaporation ntawm cov kuab tshuaj thiab yuav luag tsis nqus ntawm tus number case rau hauv daim ntawv.Yog li koj tuaj yeem luam tawm ntawm txhua yam koj xav tau thaum siv UV inks!
Txij li thaum lawv qhuav tam sim ntawd thiab tsis tso tawm tsis muaj VOC rau hauv ib puag ncig, UV luam ntawv yog suav tias yog cov cuab yeej ntsuab, muaj kev nyab xeeb rau ib puag ncig thiab tawm hauv yuav luag xoom pa roj carbon hneev taw.
Cov txheej txheem luam ntawv yuav luag zoo ib yam rau ob qho tib si pa thiab UV luam ntawv;Qhov sib txawv tuaj nyob rau hauv inks thiab cov txheej txheem ziab nrog rau cov inks.Cov pa luam yeeb offset siv cov kuab tshuaj hnyav - uas tsis yog qhov kev xaiv ntsuab tshaj plaws - vim tias lawv evaporate rau saum huab cua, tso VOC's.
Qhov zoo ntawm Offset Printing
- Loj batch luam ntawv yog nqi-zoo
- Qhov ntau luam koj luam ntawm ib tus thawj
- tus nqi tsawg dua txhua daim
- Exceptional xim txuam
- Offset tshuab luam ntawv muaj peev xwm ntawm cov ntawv loj loj
- High quality printing nrog superior clarity
Disadvantages rau Offset Printing
- Kev ua haujlwm siab thiab siv sijhawm ntev
- Me me batch printing yog qeeb heev thiab kim heev
- Lub zog-intensive, yuav tsum tau tsim ntau daim hlau txhuas rau txhua nplooj ntawv
- Cov kuab tshuaj raws li cov kuab tshuaj tso tawm cov organic sib xyaw ua ke (VOCs) thaum lawv qhuav.
Qhov zoo ntawm UV Printing
- Ua kom muaj txiaj ntsig thiab txuag lub sijhawm vim tias lub tshuab luam ntawv UV tuaj yeem kho tus cwj mem tam sim.
- Ua kom muaj zog ntxiv vim tias UV kho tus cwj mem zoo dua rau kev puas tsuaj xws li khawb thiab scuffs.
- Eco tus phooj ywg vim tias UV kho cov txheej txheem emit xoom VOCs.
- Lub sij hawm txuag thiab eco tus phooj ywg vim tias UV luam ntawv tsis xav tau lamination uas yog cov khoom siv yas.
Disadvantages ntawm UV luam ntawv
- UV tshuab luam ntawv yog kim dua li cov tshuab luam ntawv offset.
