Yuav ua li cas txheeb xyuas flexographic luam ntawv?

Flexographic luam ntawv muaj cov luam ntawv tshwj xeeb luam ntawv thiab cov txheej txheem kev ua haujlwm. Cov nta no tuaj yeem txiav txim siab los ntawm saib cov tsos, kov, kev txheeb xyuas cov ntawv luam ntawv thiab sib piv cov txiaj ntsig. Cov qauv yog raws li hauv qab no:
Them sai sai rau cov ntiv tes
Hnov cov duab
Flexographic Printing yog siv anilox rollers hloov number case. Nyob rau hauv tus txheej txheem ntawm Ink hloov cov txheej txheem, nws yog ib qho yooj yim los nyem tawm cov npoo ntawm dots. Yog li ntawd, cov teev feem ntau yog "concave" lossis "elliptical", offset dot thiab grav tshuab luam ntawv.
Nyob rau hauv cov ntsiab lus tseem ceeb, flexographic dot tshwm "Hollow," lub ntsiab lus tsis muaj nyob rau hauv qhov chaw ntawm polka dot, ua rau thaj chaw uas yuav ua qhov ntiav.
Kev zas xim dawb
Flexographic Printing siv pob tshab, qis {- siab} qhov siab ink. Yog li ntawd, cov xim ua kom dawb huv ntawm cov ntawv luam tawm yog qhov tsawg, ua rau softer, muaj xim ntau.
Flexo luam ntawv yuav tsim cov xim tsawg dua li offset luam ntawv, tab sis cov yeeb yaj kiab no ua haujlwm zoo dua hauv pob luam ntawv, qhov twg softer xim nyhuv yog qhov xav tau. Khoom du
Thaj tsam ntawm ib qho flexo luam tawm yuav muaj me ntsis "ripple" lossis "qauv tshuaj ntsuab" qauv, uas yog loaded thiab elasticity ntawm lub tshuab luam ntawv. Qhov no yog qhov tseeb tshwj xeeb thaum luam ntawv loj loj cov phiaj.
Qhov kev ntxhib los mos no yog cov luam ntawv ntawm flexographic luam ntawv thiab tuaj yeem pom nrog lub khob tsom iav lossis tsom iav.
Kov Sau Tau Zoo
Phaj Thickness
Flexographic Printing daim hlau Thickness feem ntau yog nruab nrab ntawm 1.7mm thiab 7mm, ntau dua li cov phaj tsis sib txawv raws li kev luam ntawv, tab sis feem ntau kuj nyias nyias).
Thaum nws tsis tuaj yeem txiav txim siab phaj tuab yog los ntawm kev sib chwv huv si los ntawm kev saib cov ntawv lossis rov qab ntawm lub phaj ntawm daim ntawv lossis zaj duab xis.
Ink qhuav cwj pwm
Ink hom feem ntau siv nyob rau hauv flexographic tshuab luam ntawv muaj hydro, UV inks thiab hnyav inks. Hydring number cask thiab UV inks muaj kev txawv txav kev coj cwj pwm, ua rau muaj kev xav zoo. Hydrating ink tsim ib zaj duab xis nyias tsim cov yees duab luam tawm cov dej tso rau saum npoo ntawm cov ntawv luam ntawv, ua rau lub ntsej muag zoo siab. UV number cas tom qab ziab, saum npoo yuav tsim ib zaj yeeb yaj kiab nyuaj, muab txoj kev xav nyuaj.
Cov xeeb ceem ntawm cov ntawv luam ntawv
Luam ntawv siab
Flexographic Printing siv lub teeb ua kom txo tau lub siab tiv thaiv ntawm lub tshuab luam ntawv thiab lub substrate. Qhov no ua rau cov npoo ntawm cov ntawv nyeem thiab cov duab softer, uas tsis muaj qhov cim pom.
Piv nrog gravure printing, flexographic luam tawm ua tsawg dua jagged lossis kab tawg. Piv nrog offset luam ntawv, flexographic tshuab luam ntawv dot nce yog qis dua, yog li ntawd qhov tob ntawm cov duab yog ntshiab.
Kev Sau Npe Npe
Ib qho flexographic luam ntawv xovxwm sau npe qhov tseeb yog cuam tshuam los ntawm ntau yam ntawm lub tog raj kheej raug qhov tseeb, luam ntawv nro tswj. Feem ntau hais lus, kev cuv npe yog qhov tseeb ntawm niaj hnub luam ntawv presses yog ± 0.1mm.
Thaum tshuaj xyuas cov ntawv luam tawm, koj tuaj yeem txiav txim siab yog tias lawv siv cov txheej txheem sib txawv ntawm cov qauv sib txawv lossis cov ntawv sau. Yog tias txoj kev tshaj lij yog qhov siab, tus ntug kev tsim yog ntse, nws yuav hloov tau luam tawm.
Kev sib piv nrog lwm cov qauv luam ntawv
Kev sib piv nrog teeb -} tawm
OffsTrucked - hauv cov khoom yog ci hauv cov xim thiab nplua nuj nyob rau hauv qhov tob, nrog round polka dots thiab du, txawm tias thaj chaw. Flexographic luam ntawv, ntawm qhov tod tes, muaj cov xim qis dua, jujube {{2} Daim tawv nqaij, thiab cov ntaub ntawv me ntsis.
Ib qho ntxiv, offset luam ntawv feem ntau siv PS version, PS version yog thinner, luam ntawv luam ntawv yuav tsum tau siab dua; Flexographic Printing feem ntau siv thicker PS phaj, luam ntawv luam ntawv yuav tsum tau qis dua.
Kev sib piv nrog Gravation Printing
Gravure luam ntawv tuaj yeem tsim cov xim qaim, thicker numser txheej thiab cov khoom siv tau pom zoo. Flexographic Printing ua cov soft xim, cov kua mem kua mem kua mis thiab qhov chaw smoother.
Gravure Printing siv ntse square lossis pob zeb diamond dots; Flexographic Printing siv juube - duab cov dots nrog softer sawv.
