Dab tsi yog qhov txawv ntawm flexo thiab digital xovxwm?
Flexographic (flexo) luam ntawv thiab luam ntawv digital yog ob txoj hauv kev siv hauv kev lag luam luam ntawv, txhua tus muaj nws tus yam ntxwv thiab qhov zoo. Nov yog qhov sib txawv tseem ceeb ntawm flexo thiab digital presses:
Tshuab luam ntawv:
Flexographic luam ntawv: Flexographic luam ntawv siv cov paib hloov tau yooj yim ua los ntawm roj hmab lossis photopolymer. Cov phaj no yog mounted rau ntawm lub tog raj kheej thiab tig, hloov tus number case mus rau lub substrate (xws li ntawv, cardboard, yas, los yog hlau). Flexo presses feem ntau yog siv ceev ceev- cov inks kom qhuav thiab zoo- haum rau luam ntawv ntawm ntau yam substrates.
Digital Printing: Cov luam ntawv digital cuam tshuam ncaj qha xa cov ntaub ntawv digital mus rau hauv lub substrate yam tsis tas yuav muaj daim hlau. Cov xovxwm digital siv cov thev naus laus zis xws li inkjet lossis laser siv tus number case lossis toner rau hauv substrate. Cov txheej txheem no tso cai rau kev hloov pauv cov ntaub ntawv luam tawm (VDP) thiab lub sijhawm hloov pauv sai vim tias tsis tas yuav teeb tsa phaj.
Kev teeb tsa thiab luam ntawv txheej txheem:
Flexographic luam ntawv: Kev teeb tsa flexo xovxwm suav nrog kev tsim thiab mounting cov ntawv luam ntawv rau hauv lub tog raj kheej, uas tuaj yeem siv sijhawm thiab xav tau cov neeg ua haujlwm txawj. Thaum teeb tsa, flexo presses tuaj yeem luam tawm ntawm qhov nrawm thiab tsim nyog rau kev luam ntawv loj. Lawv muaj ntau yam nyob rau hauv cov nqe lus ntawm substrate compatibility thiab muaj peev xwm lis ntau hom number case (dej-raws li, hnyav-raws li, UV- kho).
Digital Printing: Digital printing tsis xav tau daim hlau; Hloov chaw, nws ncaj qha luam cov ntaub ntawv digital mus rau substrate. Qhov no tshem tawm qhov xav tau rau lub sijhawm teeb tsa ntev uas cuam tshuam nrog phaj- ua. Cov xovxwm digital yog qhov zoo tagnrho rau kev luam ntawv luv mus rau nruab nrab thiab hloov tau yooj yim rau ntawm -xav tau lossis hloov pauv cov ntaub ntawv luam tawm. Lawv muab kev hloov pauv sai sai thiab tsim nyog rau kev luam ntawv tus kheej.
Print Quality thiab Colour Consistency:
Flexographic luam ntawv: Flexo luam ntawv tuaj yeem ua tiav siab - cov ntawv luam tawm zoo nrog cov xim zoo nkauj thiab cov cwj pwm zoo. Txawm li cas los xij, ua kom tiav cov xim sib xws ntawm cov ntawv luam loj yuav tsum tau ua tib zoo saib xyuas xim thiab hloov kho.
Digital Printing: Cov luam ntawv digital muab cov ntawv luam tawm zoo nrog cov ntsiab lus ntse thiab ua kom muaj xim zoo ib yam. Cov xovxwm digital tuaj yeem tswj cov xim gradients nyuaj thiab tsim cov duab-cov duab zoo. Lawv muaj txiaj ntsig tshwj xeeb rau cov haujlwm uas xav tau cov ntaub ntawv sib txawv lossis kev ua haujlwm luv luv uas qhov tseeb xim yog qhov tseem ceeb.
Kev txiav txim siab nqi:
Flexographic luam ntawv: Thaum pib, flexo luam ntawv yuav muaj nqi ntau dua vim yog phaj- ua thiab lub tog raj kheej teeb. Txawm li cas los xij, rau kev khiav lag luam loj, tus nqi ntawm ib chav tsev txo qis, ua rau nws raug nqi - zoo rau siab - ntim luam ntawv.
Digital Printing: Digital printing excels nyob rau hauv luv luv khiav thiab sib txawv cov ntaub ntawv luam ntawv yam tsis muaj incurring teeb nqi txuam nrog daim hlau. Txawm hais tias tus nqi ntawm ib chav yuav siab dua flexo rau kev khiav haujlwm loj, cov ntawv luam tawm digital muab cov nqi zoo rau cov khoom me me lossis cov ntawv luam tawm tus kheej.
Daim ntawv thov:
Flexographic luam ntawv: Flexo yog dav siv rau ntim cov ntaub ntawv (xws li cov ntawv lo, ntim tau yooj yim, cov thawv ntawv corrugated), ntawv xov xwm, thiab qee cov ntawv tshwj xeeb luam ntawv uas siab - ceev ntau lawm thiab kav ntev yog qhov tseem ceeb.
Digital Printing: Cov luam ntawv digital feem ntau yog siv rau cov khoom ntiag tug (xws li xa ntawv ncaj qha, cov ntaub ntawv sib txawv ntawm kev luam ntawv), luv - khiav ntim, qauv qauv, kos npe, thiab ntawm - thov luam ntawv qhov kev hloov pauv sai thiab yooj yim yog qhov tseem ceeb.
