Nyob rau hauv cov txheej txheem luam ntawv flexographic, qhov teeb meem "ghosting" tshwm sim zoo li qhov tsis txaus ntseeg, pom tsis pom. Nws tshwm sim ntawm cov npoo ntawm cov duab luam tawm lossis hauv cov khoom loj -xim xim, cuam tshuam rau qhov pom ntawm tag nrho. Qhov no tsis tsuas yog cuam tshuam rau kev zoo nkauj tab sis kuj degrades cov khoom zoo. Qhov tshwm sim no tsis yog xwm txheej; es, nws yog los ntawm kev sib koom ua ke ntawm cov cuab yeej siv, txheej txheem, cov khoom siv, thiab kev ua haujlwm. Txhawm rau tshem tawm qhov teeb meem no, kev nkag siab tob txog nws cov hauv paus hauv paus thiab kev ntsuas kev ua kom zoo yog qhov tseem ceeb.
Ghosting feem ntau tshwm sim nrog cov phaj luam ntawv siv rau ntawm lub tshuab luam ntawv flexographic. Thaum phaj engraving precision tsis txaus los yog dot tis tsis sib npaug, hloov tus number case yuav tsis sib npaug. Tsis tas li ntawd, yog tias phaj hardness siab dhau los yog qis dhau, nws cuam tshuam rau kev ua haujlwm ntawm tus number case. Tsis tas li ntawd, kev txhim kho lub phaj tsis zoo ua rau lub zog tsis sib xws hauv zos tuaj yeem ua rau muaj kuab lom los yog kev tshaib kev nqhis, nteg lub hauv paus rau ghosting. Kev hloov ntawm kev luam ntawv siab yog qhov tseem ceeb sib npaug. Kev ntxhov siab ntau dhau tuaj yeem ua rau tus number case los nyem thiab sib kis, tsim ob npaug (hnyav duab ntxoov ntxoo); Tsis txaus siab ua rau tsis txaus tus cwj mem hloov, ua rau faint ntxoov ntxoo. Hauv ntau-xim luam ntawv, sib piv cov siab ntawm cov xim xim yog qhov tseem ceeb tshwj xeeb, vim tias qhov sib txawv me me tuaj yeem cuam tshuam rau kev tso npe ruaj ntseg.
Ink khoom kuj tseem ceeb heev. Viscosity uas siab dhau los yog qis dhau cuam tshuam rau theem thiab hloov kev ua haujlwm; kev ziab kom qhuav tsis tsim nyog yuav ua rau tus number case tsis kho kom hloov pauv thib ob; Cov pigment dispersion tsis zoo tuaj yeem ua rau hauv zos sedimentation, tsim cov yeeb yaj kiab tsis sib xws. Lub substrate lub zog tseem ceeb heev. Cov ntaub ntawv uas muaj tus cwj pwm tsis zoo (xws li cov yeeb yaj kiab yas) tiv thaiv tsis zoo tus cwj mem adhesion; uneven substrate elasticity ua rau tsis sib xws deformation nyob rau hauv kev luam ntawv siab; Tsis ruaj tsis khov nto nro loj heev cuam tshuam tus cwj mem wettability ntawm cov tshuab luam ntawv flexographic.
Txhawm rau tshem tawm ghosting tag nrho, kev nqis tes ua yuav tsum pib ntawm qhov chaw. Ua ntej, thaum lub phaj ua rau lub tshuab luam ntawv flexographic, siab precision yuav tsum tau ua raws. Laser engraving thev naus laus zis yuav tsum xyuas kom meej qhov sib faib dot faib, thiab phaj hardness yuav tsum raug xaiv raws li cov yam ntxwv ntawm cov ntawv luam tawm. Kev hloov siab yuav tsum tau ua tib zoo saib xyuas, ua raws li "lub hauv paus ntsiab lus ntawm lub teeb- siab luam ntawv" - txo qhov siab thaum ua kom muaj peev xwm hloov pauv tus cwj mem. Ink formulations yuav tsum tau tailored rau lub substrate, optimizing viscosity thiab ziab ceev. Rau cov khoom tsis yog- nqus tau, kev kho corona tuaj yeem txhim kho qhov nro. Nyob rau tib lub sijhawm, kev tswj hwm nruj ntawm lub rooj cob qhia qhov kub thiab av noo ib puag ncig yog qhov tseem ceeb los tsim cov qauv luam ntawv zoo tagnrho.
Flexo tshuab luam ntawv stability yog qhov tseem ceeb. Tsis tu ncua calibrating cov menyuam concentricity, xyuas cov iav thiab bearing coj, thiab tam sim ntawd hloov cov hnub nyoog Cheebtsam yuav zoo txo qhov kev cuam tshuam ntawm mechanical kev co. Hauv kev tsim khoom, tsim nyog txo qhov nrawm nrawm tso cai rau ntau lub sijhawm rau kev hloov pauv tus lej thiab ziab, tshwj xeeb yog qhov tseem ceeb rau kev nplua - nthuav dav luam ntawv. Tsis tas li ntawd, tsim kom muaj cov txheej txheem kev khiav haujlwm thiab kev saib xyuas zoo yog qhov tseem ceeb. Kev ua thawj zaug -kev tshuaj xyuas kab lus thiab tiag- lub sijhawm tswj xim tuaj yeem tshem tawm cov teeb meem dab tsi hauv lub paj.
Nrog rau kev nce qib ntawm kev tsim khoom ntse, tshiab AI lub zeem muag tshuaj xyuas cov tshuab ua ke rau hauv lub tshuab impression flexo tam sim no tuaj yeem ntes ghosting hauv tiag -lub sijhawm thiab hloov kho cov ntawv luam tawm siv tshuab kev kawm algorithms. Cov cuab yeej no tshwj xeeb yog tsim rau siab -ceev CI (Central Impression) nias, txo lub sij hawm los ntes thiab hais txog dab phem tshaj 90%.

Hauv qab no yog cov kev ua haujlwm ntawm cov yas zaj duab xis stack flexo tshuab luam ntawv.
Ntev -Lub sij hawm ghosting kev daws teeb meem xav tau kev npaj tswv yim pib ntawm theem kev xaiv khoom siv.Rau cov lag luam feem ntau luam tawm ntawm cov yeeb yaj kiab, CI flexo presses yuav yog qhov kev xaiv zoo dua; ntim tshuab luam ntawv nrog cov khoom sib txawv tuaj yeem ua qhov tseem ceeb ntawm qhov yooj yim ntawm pawg- hom xovxwm. Tsis hais txog ntawm lub tshuab xaiv lub tswv yim flexo, nkag siab tob txog nws cov qauv kev khiav haujlwm thiab tsim kom muaj kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb rau kev tshem tawm dab.
