Pom tus number case streaks thiab ghosting hauv flexo luam ntawv? Nov yog qhov kho!

Flexographic luam ntawv yog ib txoj kev luam ntawv ncaj qha uas lub phaj luam ntawv muaj elastic, tsa cov duab. Muab ob npaug rau- ib sab daim kab xev yog siv los kho cov ntawv luam ntawv rau ntawm lub phaj rau cov menyuam, thiab cov ntawv luam ntawv yog muab nrog tus cwj mem los ntawm cov hlau lossis ceramic anilox roller. Muaj ntau yam khoom siv luam ntawv muaj peev xwm ntawm flexo ntau lawm, xws li chav tsev feem ntau - hom flexography tshuab, uas muaj ntau txoj hauv kev tsim, xws li cov ntawv sau sab saud thiab qis; Muaj ntau ntau hom inks muaj peev xwm ntawm flexo luam ntawv, xws li dej-raws li inks thiab UV inks; Muaj ntau ntau yam khoom muaj peev xwm ntawm flexo luam ntawv. Nrog xws li ib tug complex thiab varied yam, ntau yam teeb meem inevitably tshwm sim thaum lub sij hawm flexographic luam ntawv. Niaj hnub no, cia peb tham txog cov teeb meem xws li tus cwj mem streaks thiab ghosting hauv flexographic ntau lawm, nrog rau lawv cov kev daws teeb meem.

01

Luam tus number case bar

Printed number case bars feem ntau muaj kab txaij perpendicular rau luam ntawv kev taw qhia thiab sib npaug spaced nrog iav pitch qhov ntev. Qhov laj thawj tseem ceeb ntawm tus number case rods yog lub zog thiab cov neeg kho tshuab kev co, xws li qib ntawm cov neeg kho tshuab precision, seb lub iav tsim tsim nyog, thiab seb lub iav sib dhos puas tsim nyog -tag nrho cov uas tuaj yeem ua rau number case rods. Yog tias muaj teeb meem ink bar tshwm sim thaum luam ntawv, koj tuaj yeem sim cov hauv qab no:

Kho lub iav

Yog hais tias lub zog txav rov qab thiab tawm mus thaum lub sijhawm sib kis, nws tuaj yeem ua rau cov ntawv luam tawm ntawm cov khoom luam tawm thiab hnav cov ntawv luam ntawv. Txij li thaum lub helix lub kaum sab xis yog txiav txim los ntawm lub ntsiab tsav iav, qhov parameter ntawm lub phaj roller iav yuav tsum yog tib yam. Txawm li cas los xij, cov tuam txhab sib txawv muaj ntau txoj hauv kev los tshem tawm cov teebmeem axial quab yuam. Txoj hauv kev zoo tshaj plaws yog chamfer lub kaum sab saum toj ntawm lub iav ntawm 45℃kom tshem tawm ntug, tab sis lub qhov dej zoo- paub cov chaw tsim khoom siv oblique sib tsoo los ntawm cov hniav hauv paus mus rau cov hniav ntawm ob sab ntawm lub iav, nrog qhov sib tsoo qhov siab mus txog ib - thib peb lossis ib - ib nrab ntawm cov hniav qhov siab ntawm qhov siab ntawm 1/2; Cia qhov sib txawv rau axial quab yuam los tiv thaiv axial quab yuam thaum lub sij hawm ua haujlwm ntawm iav los ntawm kev ua rau iav vibration.

Stagger cov ntawv luam ntawv rau layout

Lub hom phiaj ntawm staggered typesetting yog los txo cov menyuam bounce los ntawm kev luam ntawv phaj typesetting teeb meem. Kev xyaum tau ua pov thawj tias kev cia siab ib leeg rau ntawm ob sab grating strips yog qhov nyuaj rau kev txhawb nqa phaj cov menyuam khiav tawm los ntawm qhov tsis tsim nyog layouts. Peb pom tias nyob rau hauv cov xwm txheej hnyav, phaj cov menyuam khiav tawm tuaj yeem ua rau anilox rau cov menyuam vibration, uas ua rau muaj qhov txawv txav txav txav, tshwj xeeb tshaj yog pom thaum luam ntawv ntev ntawm kev kub ceev.

Siv ob daim ntaub softer dua -sided daim kab xev ua lub ncoo rau cushioning

Siv softer ob -sided daim kab xev raws li ib tug thaub qab rau cushioning yog ib tug siv tau heev kev daws teeb meem, tab sis thaum siv txoj kev no, nws yog tsim nyog los xav txog cov pinhole teeb meem tshwm sim los ntawm nruab nrab- ntom los yog tsawg- ntom ob-sided daim kab xev thaum lub sij hawm ntawm - chaw luam ntawv.

Sau dab

Tus yam ntxwv ntawm kev luam tawm ghosting yog tias thaum luam tawm txhua yam khoom nrog ib puag ncig rov qab, cov ntawv luam ntawv hauv zos pom sib dua ntawm qhov chaw ruaj khov. Ghosting tsis yog tshwm sim los ntawm kev sau npe xim; Ghosting teeb meem kuj tuaj yeem tshwm sim thaum lub sijhawm luam ntawv monochrome. Dab feem ntau tshwm sim hauv cov ntawv nyob, thiab vim tias nws nyuaj rau piav qhia lawv lub hauv paus chiv keeb, cov neeg txawv teb chaws hu lawv Ghosting, thaum cov phooj ywg hauv tsev xa mus rau lawv li Ghosting. Nyob rau hauv luv luv, qhov ua rau ghosting yog qhov tseeb cov cim tseg los ntawm cov ntawv luam ntawv ntawm lub anilox roller.

Cov hau kev los daws teeb meem ghosting feem ntau suav nrog cov hauv qab no:

Qhov rov ua dua ib puag ncig ntawm lub phaj luam ntawv Ntau dua lossis sib npaug rau ib puag ncig ntawm cov menyuam anilox. Pom tseeb, thaum anilox cov menyuam txoj kab uas hla me me - txhais tau tias cov menyuam tig nrawm dua thiab cov number case replenishment zaus yog siab -ghosting tsis tshwm sim. Yog li ntawd, cov khoom perimeter yuav tsum tau xaiv tshwj xeeb raws li perimeter ntawm anilox roller ntawm lub tshuab luam ntawv flexo, uas yuav tsum tau txiav txim siab thaum lub sij hawm tsim cov txheej txheem tiav.

Ntawm cov qauv ntawm cov khoom imposition, cov xim blocks yuav tsum tau muab tso rau hauv qhov khoob ntawm cov qauv rov ua dua raws li qhov sib txawv ntawm lub voj voog ntawm cov menyuam anilox thiab cov phaj cov menyuam ib puag ncig, tsis yog sib tshooj nrog cov xim qub thaiv qhov chaw. Txij li thaum feem ntau ntawm peb cov khoom siv imposition printing, tsuas yog ob peb tuaj yeem ua tiav qhov ib puag ncig ntau dua lossis sib npaug rau anilox roller perimeter ib chav tsev. Yog li ntawd, thaum muaj ntau yam khoom muaj ib tug rov qab perimeter tsawg tshaj li lub perimeter ntawm lub anilox roller, peb yuav tsum xyuas qhov txawv ntawm lub perimeter ntawm lub anilox roller thiab lub phaj roller los xyuas cov xim loj block qauv ntawm txoj hauj lwm no. Yog tias muaj qhov sib txawv ntawm no, cov khoom yuav tsis muaj dab; yog tias muaj cov xim loj loj ntawm no, qhov tshwm sim ntawm ghosting yog siab heev.

Siv - cov tshuaj ua kom qhuav. Thaum koj ntsib qhov teeb meem tsim qauv no tiag tiag, kev siv qeeb - cov neeg ua kom qhuav tuaj yeem yog qhov ua tau zoo heev. Lub hom phiaj tseem ceeb ntawm kev ntxiv qeeb - cov neeg ua kom qhuav yog txhawm rau txhim kho cov qib qib ntawm tus number case ntawm cov menyuam anilox, ua kom nws qhuav kom qeeb li sai tau. Thaum luam ntawv nrog cov khoom siv UV number case, lub sijhawm ntawm ghosting yog qhov tsawg. Qhov no yog vim tias, tsis muaj UV kho cov cuab yeej, UV number case dries qeeb heev. Cov dej-raws li inks thiab cawv- cov kuab tshuaj muaj peev xwm ob qho tib si ntxiv qeeb- cov tshuaj kom qhuav, uas yuav pab tau ntau dua rau kev kho dab.

Ghosting feem ntau tshwm sim thaum lub sijhawm luam ntawv, uas muaj feem xyuam rau ntau tus neeg ua haujlwm nyiam kom nce siab thaum lub sijhawm luam ntawv. Yog li ntawd, lwm txoj hauv kev los daws ghosting yog kom txo tau lub siab ntawm inking. Qee lub sij hawm, thaum luam ntawv qeeb qeeb, ghosting pom, thiab los ntawm kev ua kom nrawm, ghosting maj mam ploj mus - qhov no yog vim li cas kev ntxhov siab txo.
