Gravure Printing Presses, raws li ib qho ntawm cov khoom tseem ceeb hauv kev luam ntawv kev lag luam nrog cov tshuab luam ntawv suav nrog kev luam ntawv, luam tawm kev ruaj ntseg, thiab kev luam ntawv ruaj ntseg. Lawv cov txiaj ntsig dag hauv cov khoom lag luam siab zoo, muaj cov yeeb yaj kiab zoo nkauj, muaj xim tshaj tawm. Cov xovxwm no kom zoo sib xws tau rau ntau tus neeg siv khoom siv rau siab- cov khoom lag luam zoo thiab ntau yam tsis muaj kev sib txawv ntawm cov luam ntawv niaj hnub.
Txawm li cas los xij, thaum lub sij hawm cov txheej txheem luam ntawv tiag tiag nrog Gravure Presses, ntau yam kev ua haujlwm ntawm cov khoom siv, thiab cov tsis tau paub txog ntawm kev ua haujlwm. Cov malfunctions tsis yog tsuas yog hloov kho luam tawm zoo, tsis yeem txo cov nqi tsim khoom, tab sis kuj yuav ncua kev ua haujlwm thiab cov khoom xa tuaj yeem ua rau cov lag luam nyiaj txiag. Thiaj li, tau txais kev nkag siab zoo ntawm cov kev ua yuam kev uas tshwm sim thaum lub ntxa luam ntawv yog qhov tseem ceeb rau kev tiv thaiv luam tawm zoo thiab txhim kho kev ua tau zoo thiab txhim kho kev ua kom zoo dua qub. Kab lus no yuav hais txog cov ncauj lus no, muab cov ncauj lus kom ntxaws ntawm cov neeg ua txhaum raug pom nrog Gravation Printing Presses.
Kev tshwm sim thiab ua rau luam tawm cov tsis xws luag
Misregume
Misregistregub yog ib qho kev ua tau zoo ib yam hauv graver prinction. Nws manifests raws li overlapping lossis cov qauv misaligned lossis cov ntawv ntawm cov luam ntawv, kev pom zoo rau kev pom thiab cov ntaub ntawv raug. Piv txwv li, hauv kev sib sau luam ntawv, cov kev coj ua tsis raug mob tuaj yeem ua rau cov lus piav qhia lossis hloov kho cov duab ntawm cov ntim khoom, cuam tshuam thaum kawg cuam tshuam rau kev muag khoom.
Cov laj thawj thawj suav nrog:
Neeg kho tshuab cov teeb pom kev tsim nyog ua rau muaj kev sib txawv ntawm cov khoom luam tawm;
Tsis Muaj Tseeb Tseeb thaum luam ntawv ua rau substrate expansion / consaction;
Phaj fais fab hnav kev hloov pauv Phaj Ntsuas Geometry thiab ua rau cov qauv sib txawv.
Dot nce
DOT nce lees txog qhov kev nthuav dav rau cov ntawv luam tawm piv rau cov paib qub, ua rau cov duab plooj thiab xim txawv txav. Hauv cov xim luam ntawv, nws ua rau kev hloov xim txawv txawv uas tsis txaus ua tau zoo. Piv txwv li, kev luam duab portrait yuav plam cov ntsiab lus ntawm lub ntsej muag thiab realism vim yog DOT nce.
Qhov tseem ceeb ua pab cuam tshuam:
Tsis raug mob viscosity binding cov kev faib tawm niaj hnub;
Ntau dhauft siab siab deforming thiab nthuav dots;
Tsis ncaj ncees substrate chaw ua rau tsis muaj inrk hloov chaw.
Xim Demiation
Kev sib txawv txawv tshwm sim thaum cov xim luam tawm txawv ntawm thawj cov duab kos, kev sib tw tseem ceeb hauv cov duab tseem ceeb xws li cov ntawv tshaj tawm thiab cov duab kos duab. Qhov kev cuam tshuam no tsis muaj tseeb no ob qho tib si tshaj tawm kev ua tau zoo thiab tus nqi muaj txiaj ntsig los ntawm kev ua tsis tiav raws tus qauv tsim.
Cov hauv paus ua rau encompass:
Qhov tsis muaj tseeb ink tsim cov xim tsis txaus ntseeg;
Suboptesal xim ua ntu zus ua ntu zus los - kev cuam tshuam cov xim cuam tshuam;
Cov sib txawv huab cua teeb pom kev cuam tshuam rau tib neeg cov xim pom thiab kev txiav txim.
Duab Doubling (Scumming)
Cov Duab Doubling tshwm sim thaum Ink hloov mus rau qhov chaw tsis pom zoo, txuas cov ntsiab lus sib cais rau hauv qhov muag plooj. Qhov kev puas siab no tau txiav cov ntsiab lus zoo - tseem ceeb hauv cov kab xov tooj cua uas nws yuav ua rau tuab, plooj, lossis sib tshuam ua ke.
Cov ntsiab lus causative xws li:
Nta ntau dhau viscosity ua rau phaj tsim;
Dhau qeeb luam ntawv ceev ceev Prolonging phaj sib cuag sijhawm;
Kev ua txhaum cai engraving qhov tob cuam tshuam kev cuam tshuam hauv kev hloov pauv tsis hloov chaw.
Kev Cuam Tshuam Cov Khoom Siv Hluav Taws Xob ntawm cov txheej txheem luam ntawv
Hloov chaw ua haujlwm tsis tiav
Raws li ib qho kev sib xyaw ua ke ntawm Gravure Presses, kev xa tawm system tsis zoo - paab -}} kev ua haujlwm cuam tshuam.
Kev coj iav ua rau cov xovxwm tsis ruaj khov, cov npe nkag siab tau zoo; saw breakage halts ntau lawm; Siv qeeb qeeb txo kev kis tau zoo, tsim qauv streaks. Piv txwv li, kev hnav hnyav hnav thaum lub siab- ceev luam ntawv yuav ua rau muaj cov khoom lag luam tsis zoo.
Kom qhuav system swb
Tseem ceeb rau gravure printing, cov teeb meem kom qhuav cov teeb meem koom nrog cov cua sov uas muaj cua sov, thiab cov kev tswj kom kub.
Cov cua sov ua kom puas tsuaj tiv thaiv tus mem tes tsim nyog, ua rau smearing thiab thaiv; Qhov chaw txaus kom txaus ua tau Chamber cov av noo, ncua qeeb; Kev tswj qhov kub thiab kub tsis ua tiav kev ua tsov rog thiab siv tsis tau thaum muaj kev cuam tshuam ntev, lossis tsis txaus}}} ob qho tib si ua rau smearing tsis meej.
Hluav Taws Xob Tswj System swb
Ua haujlwm raws li cov xovxwm neural hub, hluav taws xob tsis ua haujlwm zoo nkauj luv luv, sensor malfunctions, thiab software slas.
Luv luv luv tiv thaiv tshuab pib thiab kev puas tsuaj tiv thaiv; Ua tsis tau cov sensors disapped parameter xyuas (piv txwv li, nro), destabilizing kev ua haujlwm; Software ua yuam kev yuam kev ua neeg. Piv txwv li, faulty nro sensors ncaj qha
