UV yob-rau-yob tshuab luam ntawv tau hloov pauv kev lag luam luam ntawv, xa cov ntawv luam tawm zoo ntawm ntau yam substrates. Cov tshuab no siv lub teeb ultraviolet los kho cov inks, ua rau cov xim zoo nkauj thiab cov ntawv luam tawm ntev. Txawm li cas los xij, zoo li txhua yam thev naus laus zis, lawv tuaj yeem ntsib teeb meem uas cuam tshuam rau kev ua tau zoo thiab cov khoom tsim tawm. Kev nkag siab txog cov teeb meem sib xws thiab lawv cov kev daws teeb meem tuaj yeem pab cov neeg ua haujlwm tswj hwm kev ua tau zoo thiab ua kom cov txiaj ntsig zoo.
Ib qho ntawm cov teeb meem feem ntau nrog UV yob-rau-yob tshuab luam ntawv yog tsis txaus ink curing. Yog tias tus number case tsis kho tag nrho, nws tuaj yeem ua rau smearing, adhesion tsis zoo, thiab tag nrho cov ntawv luam tawm tsis zoo. Qhov teeb meem no tuaj yeem tshwm sim los ntawm ntau yam:
Tsis txaus UV raug:Xyuas kom tseeb tias lub teeb UV ua haujlwm zoo thiab nyob ntawm qhov kev ncua deb ntawm lub substrate. Tshawb xyuas UV siv tsis tu ncua thiab hloov lub teeb UV yog tias tsim nyog.
Ink formulation yuam kev:Kev siv cov inks uas tsis sib haum nrog lub tshuab lossis cov substrate yuav ua rau muaj teeb meem kho. Ib txwm siv cov inks pom zoo los ntawm cov chaw tsim khoom kom tau txais txiaj ntsig zoo tshaj plaws.
Kev ceev ceev:Yog tias koj luam ntawv nrawm dhau, tus cwj mem yuav tsis muaj sijhawm txaus los kho. Kho qhov chaw ceev kom paub meej tias tus number case kho kom txaus tsis cuam tshuam rau kev ua haujlwm ntau lawm.
Lub clogged printhead yog lwm qhov teeb meem uas tuaj yeem cuam tshuam cov txheej txheem luam ntawv. Qhov no tuaj yeem ua rau streaks, tsis muaj xim, lossis tsis sib xws. Txhawm rau daws qhov teeb meem no, ua cov hauv qab no:
Kev saib xyuas tsis tu ncua:Tsim kom muaj lub sijhawm tu ncua uas suav nrog kev ntxuav lub taub hau. Siv cov chaw tsim khoom pom zoo cov kev daws teeb meem thiab cov txheej txheem los tiv thaiv kev tsim.
Txheeb xyuas tus number case viscosity:Xyuas kom tseeb tias tus number case viscosity nyob rau hauv qhov kev pom zoo. Yog tias tus number case tuab heev, nws yuav ua rau txhaws. Yog tias tsim nyog, kho tus number case formula los yog kub.
Kev siv cov lim dej:Txhim kho cov ntxaij lim dej hauv cov kab ntim khoom kom tsis txhob muaj cov khib nyiab nkag mus rau hauv lub taub hau. Tshawb xyuas thiab hloov cov lim dej no tsis tu ncua kom tswj tau qhov dej ntws zoo.
Hauv UV yob-rau-yob luam ntawv, kev tshaj tawm xov xwm yog qhov tseem ceeb. Cov teeb meem xws li xov xwm wrinkling, misalignment, los yog cov teeb meem pub tuaj yeem ua rau nkim khoom thiab sijhawm. Los daws cov teeb meem no:
Kev teeb tsa kom nruj:Xyuas kom tseeb tias cov xov xwm yog loaded nrog qhov tseeb nro. Kev nro ntau dhau yuav ua rau cov xov xwm nthuav tawm, qhov nruj me ntsis yuav ua rau nws plam.
Alignment check:Tsis tu ncua xyuas cov xov xwm pub kev sib raug zoo. Misalignment tuaj yeem ua rau skewed prints thiab cov khoom pov tseg. Kho cov ntawv qhia raws li xav tau los xyuas kom muaj kev sib raug zoo.
Environmental tej yam kev mob:Khaws qhov chaw luam ntawv ruaj khov. Cov av noo siab lossis kub hloov pauv tuaj yeem cuam tshuam rau cov khoom siv xov xwm, ua rau muaj teeb meem kev ua haujlwm. Siv lub tshuab ntsuas kub kom tswj tau qhov chaw zoo.
Ua kom tiav cov xim zoo ib yam yog qhov tseem ceeb rau kev luam ntawv. Xim variations tuaj yeem tshwm sim los ntawm cov hauv qab no:
Calibration:Tsis tu ncua calibrate koj lub tshuab luam ntawv kom paub meej xim. Qhov no suav nrog kev kho cov xim profile thiab ua cov ntawv luam tawm kom paub tseeb qhov sib xws.
Ink batch variations:Xim xim yuav txawv me ntsis ntawm batch rau batch. Rau qhov sib xws, ib txwm siv tus cwj mem los ntawm tib pawg.
Qhov sib txawv ntawm substrate:Cov substrates sib txawv nqus cov cwj mem sib txawv, cuam tshuam cov xim tso zis. Ntsuam xyuas cov substrates tshiab los txiav txim seb lawv cuam tshuam li cas nrog cov inks siv.
nyob rau hauv xaus
UV yob-rau-yob presses muaj zog thiab, thaum khiav kom raug, tsim cov txiaj ntsig zoo. Los ntawm kev nkag siab thiab daws teeb meem ntau yam xws li cov teeb meem ntawm tus number case curing, printhead clogs, media tuav cov teeb meem, thiab xim sib xws, cov neeg ua haujlwm tuaj yeem txhim kho lawv cov txheej txheem luam ntawv thiab ua tiav cov txiaj ntsig zoo. Kev saib xyuas tsis tu ncua, kev teeb tsa kom raug, thiab kev saib xyuas kom meej yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws ntawm cov xovxwm siab heev.
