Nyob rau hauv cov txheej txheem flexographic tshuab, qeeb number case kom qhuav ua rau smudging yog ib qho nyuaj rau cov tuam txhab luam ntawv. Qhov no tsis tsuas yog cuam tshuam rau kev luam ntawv zoo thiab ua kom cov khoom pov tseg, tab sis kuj txo cov kev tsim khoom thiab tseem tuaj yeem ncua sijhawm xa khoom. Yuav daws qhov teeb meem no li cas? Peb muab cov kev daws teeb meem uas suav nrog kev xaiv tus number case, kev ua kom zoo dua qub, kev hloov khoom dua tshiab, thiab kev tswj ib puag ncig los pab koj tshem tawm cov smudging thiab ua tiav cov khoom lag luam ruaj khov, ua haujlwm zoo.
● Ink Selection & Formula Optimization – daws teeb meem ziab ntawm qhov chaw
Rau cov tshuab luam ntawv flexo, xaiv tus number case thiab kev tsim qauv yog qhov tseem ceeb rau kev daws teeb meem ziab. Peb pom zoo kom qhuav cov inks sai, xws li cov kuab tshuaj raws li cov kuab tshuaj uas muaj cov tshuaj tiv thaiv kab mob siab lossis cov dej-raws li inks nrog cov tshuab ziab khaub ncaws. Rau qhov siab tshaj plaws kom qhuav ceev, UV inks ua ke nrog ultraviolet curing systems yog qhov kev xaiv zoo tshaj plaws. Kho cov kuab tshuaj sib piv-xws li nce ethanol lossis ethyl acetate cov ntsiab lus- tuaj yeem txhim kho kev ua haujlwm kom qhuav thaum tuav tus number case stability. Tsis tas li ntawd, xaiv cov khoom ziab kom zoo (piv txwv li, cobalt / manganese driers rau oxidative drying inks lossis tshwj xeeb penetrants rau absorbent substrates) ua kom pom kev zoo.
● Kev Txhim Kho Kom Qhuav Qhuav - Txhim kho kev ua tau zoo
Kev ua haujlwm ntawm cov tshuab ziab khaub ncaws hauv flexo tshuab luam ntawv ncaj qha cuam tshuam cov txiaj ntsig. Kev tshuaj xyuas cov tshuab ziab khaub ncaws tsis tu ncua kom ntseeg tau tias qhov kub thiab txias (50-80 ° C rau cov kuab tshuaj hnyav, me ntsis qis dua rau cov dej-raws li) thiab tsis muaj kev cuam tshuam cov huab cua. Rau cov ntawv thov xav tau, hloov mus rau infrared kom qhuav rau hauv zos efficiency lossis UV curing rau ziab sai. Cov tshuab ziab khaub ncaws txias yog qhov tshwj xeeb tshaj yog rau cov yeeb yaj kiab uas tsis yog nqus dej los tiv thaiv tus number case rewetting.
● Printing Process Optimization – Kho Cov Txheej Txheem Ntau Lawm
Nyob rau hauv flexographic tshuab luam ntawv, optimizing ntau lawm tsis ho pab kom qhuav efficiency. Kev tswj kev luam ntawv ceev yog qhov tseem ceeb heev - kev ceev ntau dhau tiv thaiv kom qhuav ua ntej qhov chaw luam ntawv tom ntej. Kho qhov nrawm raws li tus cwj mem lub zog thiab lub peev xwm tshuab ziab khaub ncaws. Tswj tus number case zaj duab xis thickness ntawm kev xaiv anilox rau cov menyuam thiab cov number case ntim tiv thaiv kev tsim ntau dhau. Rau ntau xim luam ntawv, nce chaw nres tsheb sib nrug los yog ntxiv cov tshuab ziab khaub ncaws ncua sij hawm ziab.
● Ib puag ncig & Substrate Adaptation – Qhov tseem ceeb sab nrauv
Ib puag ncig tej yam kev mob nyob rau hauv flexo tshuab luam ntawv ua hauj lwm zoo heev cuam tshuam rau ziab. Khaws lub khw hauv pem teb kub ntawm 20-25 ° C thiab av noo ntawm 50-60%. Siv cov dehumidifiers hauv lub caij ntub dej. Substrate pretreatment (xws li, kev kho mob corona rau PE / PET films) txhim kho cov xim adhesion thiab txo cov kev ua kom qhuav.
Kev kho mob Corona
Humidity Control
Thaum kawg, txoj kev npaj kho kom ruaj khov ua kom muaj kev ruaj ntseg mus ntev. Tsis tu ncua ntxuav lub tshuab ziab khaub ncaws thiab cua sov cov ntsiab lus, tshuaj xyuas anilox rau cov menyuam hnav, thiab siv cov tshuab ziab khaub ncaws los saib xyuas cov ntawv luam tawm - cov kauj ruam tseem ceeb hauv kev tiv thaiv kom qhuav cov teeb meem.
