Qhov sib txawv tseem ceeb ntawm gravure printing, flexographic printing, thiab letterpress printing yog raws li nram no:
Gravure luam ntawv:
Phaj Hom: Gravure printing siv cov duab engraved los yog etched rau hauv hlau los yog yas daim hlau. Cov chaw recessed no tuav tus number case thiab xa mus rau cov khoom luam tawm thaum lub sijhawm luam ntawv.
Daim ntawv thov: Gravure luam ntawv feem ntau yog siv rau kev luam ntawv loj xws li ntim khoom, ntawv lo, ntawv xov xwm, ntawv ntsa, ntawv dai, thiab lwm yam.
Cov yam ntxwv: Gravure luam ntawv paub txog nws qhov kev kub ceev, zoo, thiab kev daws teeb meem siab, ua rau nws tsim nyog rau cov khoom ntim siab.
Flexographic luam ntawv:
Phaj Hom: Flexographic luam ntawv siv cov roj hmab hloov tau yooj yim lossis cov phaj polymer los hloov cov number case. Cov phaj no feem ntau yog tuab dua thiab tuaj yeem hloov mus rau qhov chaw luam ntawv tsis tu ncua.
Daim ntaub ntawv: Flexographic luam ntawv yog tsim rau ntau yam ntaub ntawv, xws li ntim, ntawv, hnab, ntawv, yas zaj duab xis, thiab feem ntau yog siv los luam tawm ntawm lub thawv ntim.
Yam ntxwv: Flexographic luam ntawv yog ntau yam, haum rau ntau yam luam ntawv cov ntaub ntawv thiab qhov chaw, thiab muaj peev xwm luam ntawv ceev, ua rau nws zoo tagnrho rau nruab nrab mus rau loj-ntim ntau lawm.
Ntawv luam ntawv:
Phaj Hom: Letterpress luam ntawv siv cov ntawv tsa suab, qhov twg cov duab thiab cov ntawv sau tau tsa, thiab tus number case yog siv rau thaj tsam ntawm lub phaj.
Daim ntawv thov: Letterpress luam ntawv tau dav siv hauv keeb kwm ntawm kev luam ntawv rau cov phau ntawv, cov ntawv tshaj tawm, daim npav tos txais, thiab lwm yam, tab sis nws cov ntawv siv niaj hnub no kuj txwv.
Yam ntxwv: Letterpress printing yog tus cwj pwm los ntawm cov ntawv sau thiab cov duab, ua kom haum rau cov ntawv nyeem thiab cov qauv uas yuav tsum tau sawv tawm. Txawm li cas los xij, nws muaj qhov nrawm nrawm dua thiab tsis haum rau kev luam ntawv loj.
Cov txheej txheem luam ntawv no txawv ntawm txoj kev luam ntawv, thaj chaw thov, thiab cov yam ntxwv. Xaiv cov txheej txheem luam ntawv tsim nyog nyob ntawm qhov yuav tsum tau ua ntawm kev luam ntawv thiab cov ntaub ntawv siv. Txhua tus txheej txheem muaj nws qhov tshwj xeeb zoo thiab kev txwv, thiab kev xaiv yuav tsum tau ua raws li cov kev xav tau tshwj xeeb.
