Cov Haujlwm Loj Haujlwm Feem Ua Si hauv Cov Ntawv Sau Npe
Txawm tias cov tuam txhab lag luam hauv lub tuam txhab ua lag luam mus rau cov tshuab luam ntawv, ntau lub tshuab luam ntawv tseem siv cov luam tawm thiab cov qauv siv luam tawm uas tau ua qauv luam tawm ntau tshaj li ib puas xyoo.
Offset Kev Sau Ntawv
Offset lithography - yog ib qho ntawm ntau tshaj plaws los luam tawm ntawm sab sau-siv luam daim hlau kom hloov cov duab rau ntawv los yog lwm cov ntawv sab nrauv. Daim hlau no feem ntau yog ua los ntawm ib daim ntawv nyias nyias hlau, tab sis qee lub sij hawm, cov ntawv yuav yog yas, yas los yog ntawv. Hlau daim hlau muaj nqi ntau tshaj ntawv lossis lwm daim ntawv, tab sis lawv ntev dua, tsim cov duab zoo tshaj plaws rau ntawm daim ntawv thiab muaj ntau dua cov ntaub ntawv tshaj li cov ntawv ua los ntawm lwm cov ntaub ntawv.
Ib daim duab raug muab tso rau hauv cov ntawv luam tawm uas siv cov tshuab photomechanical los yog photochemical rau lub sij hawm uas muaj npe hu ua prepress-ib phaj rau txhua xim xim uas yuav tsum luam tawm.
Cov ntawv xov xwm txuas nrog rau cov phom thooj voos kheej kheej ntawm cov ntawv xovxwm. Muab lub thawv thiab dej pleev rau cov thawv thiab tom qab ntawd yuav pauv mus rau ib lub thawv ntim nruab nrab (daim pam) thiab tom qab ntawd rau lub phaj, qhov uas tus lej khawm nkag mus rau ntawm thaj chaw ntawm lub phaj. Ces tus number case hloov mus rau ntawv.
Prepress Plating Kev Txiav Txim Siab
Txoj haujlwm luam tawm uas luam tawm hauv cov xim dub xwb yuav tsum yog ib lub phaj xwb. Txoj haujlwm luam tawm uas luam tawm hauv xim liab thiab dub dub xav tau ob daim hlau. Feem ntau, cov ntawv ntau ntxiv uas xav tau los sau cov haujlwm, tus nqi ntau dua.
Tej yam ua nyuab dua thaum tha xim duab koom tes. Offset luam ntawv yuav tsum sib cais ntawm cov duab liab qab ua plaub fab xim-cyan, magenta, daj thiab dub. Cov ntaub ntawv CMYK nws thiaj li dhau los ua plaub daim phiaj uas khiav ntawm lub luam ntawv xov xwm tib lub sijhawm rau plaub lub thooj voos kheej kheej. CMYK txawv ntawm RGB (liab, ntsuab, xiav) xim qauv koj pom ntawm koj lub computer screen. Cov ntaub ntawv digital rau txhua txoj haujlwm luam tau raug soj ntsuam thiab kho kom tsawg dua cov xov xwm uas tsim nyog los luam tawm ntawm qhov project thiab hloov xim cov duab lossis cov ntaub ntawv nyuab rau CYMK nkaus xwb.
Muaj qee zaum, muaj ntau tshaj plaub daim phiaj-yog tias lub logo yuav tsum tshwm nyob rau hauv Pantone xim, piv txwv, los yog ib qho xim muaj xim hlau ntxiv nrog rau cov duab tho xim.
Nyob ntawm seb qhov loj ntawm cov ntawv luam tiav, ntau daim ntawv luam tawm tau luam tawm ntawm ib daim ntawv loj loj thiab tom qab ntawd mam txiav txim siab tom qab ntawd. Thaum ib txoj haujlwm tau luam tawm ob sab ntawm nplooj ntawv, lub department tus kws kho mob tuaj yeem xa daim duab los luam tawm tag nrho cov phaum ntawm ib lub phaj thiab tag nrho cov nraub qaum ntawm lwm tus, kev siv lub npe hu ua sheetwise, los yog nrog ob sab pem hauv ntej thiab nraub qaum ntawm ib phaj hauv kev ua hauj lwm-thiab-tig lossis haujlwm-thiab-tumble layout. Ntawm no, sheetwise feem ntau yog kim tshaj vim tias nws yuav siv ob npaug ntawm cov paib. Nyob ntawm qhov loj ntawm qhov project, cov naj npawb ntawm cov ntawv thiab cov ntawv me me, lub chav faj fab npaj xaiv txoj kev ua haujlwm tshaj plaws rau txoj haujlwm ntawm cov phiaj.
Lwm Hom Phaj
Hauv kev luam ntawv, qhov screen yog qhov sib npaug ntawm cov ntawv phaj. Nws tau tsim manually los yog duab thaij thiab feem ntau yog ib qho ntxeem tau los yog cov hlau tsis muaj steel hlau ntxig rau hauv ib kab.
Cov ntawv xov xwm feem ntau yog tsim rau luv sau luam tsis tas ze los yog kov cov xim uas yuav tsum tau ntaiv . Npaj koj tus qauv kom daim ntawv yuav siv tau yog tias koj xav txuag nyiaj. Tsis yog txhua tus lag luam luam ntawv muab qhov kev xaiv no.
