Muaj qhov sib txawv tseem ceeb ntawm kev luam ntawv flexographic thiab gravure luam ntawv hauv ntau yam. Cov hauv qab no yog ib qho kev sib piv tshwj xeeb:
1. Txhais thiab cov khoom
Flexographic luam ntawv: tseem hu ua flexographic luam ntawv, yog lub tshuab luam ntawv uas siv cov ntaub ntawv hloov tau yooj yim (xws li resin, roj hmab lossis yas) los ua cov ntawv luam ntawv. Cov tshuab no tsuas yog siv cov menyuam anilox los hloov cov number case thiab tus kws kho mob hniav los tswj tus number case.
Gravure printing: Nws yog ib lub tshuab luam ntawv uas siv lub gravure ua lub phaj luam ntawv. Lub gravure yog ib lub phaj nrog grooves rau ntawm qhov chaw, uas yog sau nrog number case. Thaum lub gravure hu rau lub substrate, tus number case yog pauv mus rau lub substrate.
2. Cov txheej txheem luam ntawv thiab cov khoom siv
Flexographic luam ntawv: Cov txheej txheem yog qhov yooj yim, feem ntau suav nrog muab cov phaj flexographic rau ntawm lub substrate, siv cov anilox cov menyuam hloov cov number case rau lub phaj flexographic, thiab tom qab ntawd siv tus kws kho hniav los tswj tus number case. Flexographic tshuab luam ntawv feem ntau yog yooj yim rau kev khiav lag luam thiab siv tus cwj mem me me.
Gravure printing: Cov txheej txheem yog qhov nyuaj, feem ntau suav nrog kev hloov tus cwj mem los ntawm gravure mus rau substrate. Cov txheej txheem no feem ntau yuav tsum tau siv lub tswv yim rau cov menyuam siv lub siab kom coj lub gravure mus rau hauv kev sib cuag nrog lub substrate. Cov cuab yeej luam ntawv Gravure kuj tseem kim vim nws yuav tsum muaj kev tswj xyuas zoo thiab siab - zoo gravure daim hlau.
3. Printing yam ntxwv thiab daim ntawv thov cheeb tsam
Flexographic luam ntawv:
Lub phaj luam ntawv yog mos thiab yoog raws, nrog kev luam ntawv siab.
Haum rau ntau yam substrates, xws li yas, ntawv, zaj duab xis, thiab lwm yam.
Feem ntau yog siv los ntim cov ntawv luam tawm, xws li cov yeeb yaj kiab yas, cov ntawv luam yeeb, ntawv txhuas ntawv, thiab lwm yam.
Cov duab thiab cov ntawv raug raug qis, tab sis nws yog tus nqi - zoo thiab haum rau kev luam ntawv loj.
Gravure luam ntawv:
Cov khoom luam tawm muaj txheej tuab tuab, xim ci thiab siab saturation.
Lub tshuab luam ntawv phaj muaj kev luam ntawv siab thiab ruaj khov luam ntawv zoo.
Haum rau cov khoom luam tawm nrog cov kev xav tau siab rau kev pom meej thiab nthuav dav, xws li ntawv xov xwm, ntawv xov xwm, duab albums thiab lwm yam kev tshaj tawm.
Nws kuj yog siv los ua cov khoom luam tawm ntawm cov hniav hlau phaj thiab iav thiab lwm yam ntaub ntawv.
