Lub phaj luam ntawv yog ib qho tseem ceeb hauv cov txheej txheem ntawm kev hloov cov duab mus rau ib lub substrate xws li ntawv lossis ntaub. Lawv siv ntau hom kev luam ntawv, suav nrog offset, flexographic thiab gravure printing. Txhua homluam ntawv phajmuaj cov yam ntxwv tshwj xeeb thiab tsim nyog rau kev luam ntawv tshwj xeeb. Hauv tsab xov xwm no, peb yuav tshawb txog peb yam tseem ceeb ntawm cov ntawv luam tawm thiab lawv cov kev siv.
Offset luam ntawv phaj yog dav siv hauv kev lag luam luam ntawv vim lawv cov khoom siv zoo thiab ntau yam. Cov phaj no feem ntau yog ua los ntawm txhuas los yog polyester thiab coated nrog ib tug photosensitive emulsion. Cov duab yuav tsum tau luam tawm yog pauv mus rau lub phaj luam ntawv uas siv cov txheej txheem yees duab uas cov chaw tsis yog duab raug kho kom cov dej nqus dej thiab cov duab cov duab tau kho kom ua tus cwj mem nqus.
Muaj ob yam tseem ceeb ntawm offset printing phaj: tsoos analog luam ntawv daim hlau thiab niaj hnub digital luam ntawv phaj. Tsoos analog luam ntawv daim hlau yuav tsum tau cais cov duab tsis zoo, uas yog siv los nthuav cov phaj. Cov phiajcim digital, ntawm qhov tod tes, tuaj yeem ua duab ncaj qha siv computer-to-phaj (CTP) thev naus laus zis, tshem tawm qhov xav tau ntawm zaj duab xis, ua rau cov txheej txheem ua haujlwm zoo dua.

Nruab nrab nyuaj phaj, optimized rau luam ntawv ntawm designs uas muab halftones thiab solids nyob rau hauv ib lub phaj.Zoo rau tag nrho cov absorbent thiab non-absorbent feem ntau siv substrates (ie yas thiab txhuas ntawv ci, coated thiab uncoated boards, preprint liner).High khoom ceev thiab yam tsawg kawg nkaus qhov nce hauv halftone.Wide raug latitude thiab zoo nyem qhov tob.Suitable rau siv nrog dej thiab cawv-raws li luam ntawv inks.
Offset luam ntawv daim hlau paub txog lawv lub peev xwm los tsim cov duab siab thiab nthuav dav, ua rau lawv haum rau cov ntaub ntawv luam tawm xws li cov ntawv xov xwm, daim ntawv qhia thiab ntim. Lawv kuj muab cov txiaj ntsig ntawm kev hloov pauv sai thiab yooj yim, ua rau lub sijhawm ua haujlwm sai dua.
Flexographic luam ntawv phaj, Flexographic luam ntawv, los yog flexographic luam ntawv, yog ib qho kev xaiv nrov rau luam tawm ntawm cov khoom siv yooj yim xws li yas, ntawv, thiab duab los qhia. Flexographic luam ntawv phaj feem ntau yog ua los ntawm roj hmab lossis cov ntaub ntawv photopolymer thiab mounted rau cov menyuam rau cov txheej txheem luam ntawv. Cov phiajcim no yog tsim los hloov tus cwj mem mus rau lub substrate uas siv cov kev hloov pauv yooj yim uas ua raws li qhov sib txawv ntawm qhov chaw luam ntawv.
Photopolymer daim hlau yog cov feem ntau siv flexographic luam ntawv daim hlau. Lawv yog tsim los ntawm kev nthuav tawm cov khoom siv photopolymer los ntawm qhov tsis zoo rau UV lub teeb, uas ua rau cov duab tawv tawv thaum tawm hauv qhov chaw tsis yog duab mos thiab ntxuav. Cov txheej txheem ua kom cov duab zoo sib xws thiab zoo ib yam, ua cov ntawv photopolymer zoo tagnrho rau cov ntawv luam ntawv, ntim thiab ntim corrugated.
Flexographic luam ntawv daim hlau paub txog lawv lub peev xwm los lis ntau yam inks thiab substrates, ua rau lawv haum rau ntau yam kev siv hauv kev ntim khoom thiab kev lag luam. Lawv kuj muaj peev xwm luam ntawv ceev ceev, ua rau lawv xaiv tus nqi zoo rau kev luam ntawv siab.
Gravure luam ntawv phaj, Gravure printing, tseem hu ua gravure printing, yog ib tug high-zoo, high-volume luam ntawv txheej txheem feem ntau siv los tsim cov ntawv xov xwm, catalogs, thiab zoo nkauj prints. Gravure luam ntawv daim hlau yog ua los ntawm tooj liab los yog chromed hlau thiab muaj cov hlwb recessed los yog qhov uas tuav tus number case. Cov duab yog etched los yog carved rau ntawm lub phaj siv cov txheej txheem tshuaj los yog txhua yam, tsim kom muaj cov qauv ntawm cov hlwb uas sib haum rau cov duab uas xav tau.
Ob hom loj ntawm gravure luam ntawv phaj yog lub tog raj kheej thiab flatbed. Lub tog raj kheej daim hlau yog qhwv ib ncig ntawm lub tog raj kheej thiab siv rau kev luam ntawv tas mus li, thaum daim hlau tiaj tus siv rau kev luam ntawv luv luv thiab kev siv tshwj xeeb. Gravure luam ntawv daim hlau muaj peev xwm ua tau zoo nthuav dav thiab ntau lub suab nrov, ua rau lawv tsim nyog rau kev tsim cov duab zoo.
Gravure luam ntawv daim hlau yog paub txog lawv cov durability thiab ntev luam ntawv sau, ua rau lawv thawj xaiv rau high-volume printing hauj lwm. Lawv kuj muaj peev xwm luam tawm ntawm ntau yam substrates, nrog rau cov ntawv, yas thiab hlau, ua rau lawv haum rau kev luam ntawv sib txawv.
Hauv cov ntsiab lus, cov ntawv luam ntawv ua lub luag haujlwm tseem ceeb hauv kev lag luam luam ntawv, thiab nkag siab txog ntau hom ntawv luam ntawv yog qhov tseem ceeb rau kev xaiv txoj hauv kev rau ib txoj haujlwm luam ntawv. Txawm tias offset luam ntawv daim hlau rau high-resolution lag luam luam ntawv, flexographic luam ntawv phaj rau saj zawg zog ntim, los yog gravureluam ntawv daim hlaurau cov ntawv luam tawm siab, txhua hom ntawv luam ntawv muaj qhov tshwj xeeb zoo thiab muaj nuj nqi. Los ntawm kev xaiv cov ntawv luam ntawv zoo, cov tshuab luam ntawv tuaj yeem ua tiav cov ntawv luam tawm zoo thiab kev ua haujlwm uas lawv xav tau rau lawv cov kev xav tau tshwj xeeb luam ntawv.
