To To taub cov xim 4 xim offset tshuab luam ntawv
CINYK Cov Qauv Ciaj Ua Qauv
Lub 4 xim offset tshuab luam ntawv ua haujlwm siv cov qauv CMYK, uas sawv rau Cyan, Daj, thiab tus yuam sij (dub). Tsis zoo li RGB cov qauv siv rau cov qauv digital, CMYK yog cov qauv sib dhos kom haum rau kev luam tawm dawb substrates. Los ntawm overlaying sib txawv feem pua ntawm plaub inks, lub tshuab tuaj yeem yug me nyuam ib qho kev twv txiaj dav dav ntawm cov xim.
Cov Cheebtsam Tseem Ceeb
Ib txwm muaj 4 xim offset tshuab luam ntawv muaj ntau cov ntsiab lus tseem ceeb:
- Phaj Thooj Voos Kheej: Txhua ntawm plaub xim muaj nws tus kheej phaj lub tog raj kheej, uas tuav lub tshuab luam ntawv etched nrog cov duab yuav tsum luam tawm.
- Blamet Thooj Voos Kheej: Cov thooj voos kheej kheej tau txais cov duab number case ntawm lub tog raj kheej phaj thiab hloov nws mus rau daim ntawv.
- Pom zoo thooj voos kheej kheej: Lawv nias daim ntawv tiv thaiv daim pam tog raj kheej los xyuas kom meej tus ntxhiab hloov.
- Number case thiab dampening tshuab: Txhua chav tsev xim muaj tus cwjpwm hauv tus ceg thiab dampening system los thov number case thiab dej rau cov phiaj, feem.
Txheej txheem luam ntawv
1. Prepress: npaj cov phiaj
Cov txheej txheem pib nrog kev tsim cov phiaj hlau rau txhua xim. Siv lub computer-rau-phaj (CTP) thev naus laus zis, cov duab digital tau sib cais rau hauv CMYK Cheebtsam, thiab txhua tus tau pauv mus rau cov hlau lossis polyester. Daim duab thaj chaw ntawm lub phaj tau kho kom nyiam qhov mem kua, thaum tsis muaj cov duab tsis nyiam dej, siv tus roj thiab dej tsis sib tov.
2. Inking thiab dampening
Txhua lub tog raj kheej lub tog raj rotates los ntawm kev daws cov dej ntws los ntawm cov chaw tsis muaj duab, tiv thaiv kab mob los ntawm kev ua kom muaj. Tom qab, qhov ntsuas qhov system siv number case rau cov duab duab. Qhov pom tau sib npaug ntawm number case thiab dej yog qhov tseem ceeb rau kev tswj cov ntawv luam tau zoo.
Tus me
3. Offset hloov
Cov duab number case ntawm lub phaj fais fab hloov mus rau daim pam lub tog raj kheej, uas tom qab ntawd nias nws mus rau daim pam thiab cov thooj voos kheej kheej. Cov txheej txheem indirect no, hu ua "offset," txo cov phiaj rau ntawm cov phiaj ntawv thiab tso cai rau cov hom ntawv zoo ntawm ntau hom ntawv.
4. Cov ntaub ntawv thov xim
Cov ntawv txav mus rau ntawm plaub cais cov ntawv luam tawm, txhua qhov thov ib ntawm CMYK Inks hauv ntu. Kev sau npe kom meej kom ntseeg tau tias cov xim kho kom raug kom tsim cov duab duab kawg. Niaj hnub 4 xim offset luam ntawv tshuab feem ntau suav nrog kev muab npe siv rau npe kom muaj cov txheej txheem ua kom raws li cov txheej txheem.
Tswjhwm Zoo thiab Kev Tswj Xim Xim
Ib nrab thiab cov qauv dot
Yuav kom muaj cov duab txuas txuas ntxiv, cov xim 4 xim offset tshuab luam ntawv siv ib nrab, qhov twg cov duab tau tawg rau hauv cov dots ntawm cov sib txawv ntawm cov ntau thiab tsawg thiab. Cov txheej txheem no ua rau cov kev ua tsis zoo ntawm gradients thiab ntxoov ntxoo.
Ntaiv thiab overrprinting
Txhawm rau them nyiaj rau kev coj tsis zoo me me thaum lub tshuab luam ntawv, cov tswv yim zoo li cuab yeej tau ua haujlwm. Cuab cuab yuav ua rau muaj kev cuam tshuam me ntsis ntawm cov xim uas nyob ib sab los tiv thaiv cov khoob. Kev siv hluav taws xob, qhov twg ib qho xim tau luam tawm dua lwm tus, kuj yog siv tau los txhim kho cov xim nplua nuj thiab tiv thaiv cov teeb meem rau npe.
Nyob rau hauv cov xim tshem tawm (UCR)
Hauv cov cheeb tsam uas tag nrho peb CMY inks sib tshooj los tsim cov xim dub, UCR txo tus nqi ntawm CMY inks thiab hloov lawv nrog cov mem kua dub. Qhov kev sib cuag no minimizes ink kev siv thiab tiv thaiv teeb meem xws li number cask smudging lossis daim ntawv saturation.

Qhov Zoo Ntawm 4 Xim Offset Tshuab Luam Ntawv
- Cov duab siab zoo: Cov txheej txheem offset muab cov duab ntse, ntxuav cov duab thiab cov ntawv nyeem, nrog cov xim zoo nkauj hla dhau cov ntawv loj.
- Kev ua tau zoo rau cov khoom loj: Ib zaug teeb tsa, 4 xim offset tshuab luam ntawv tuaj yeem tsim ntau txhiab ntawm cov neeg luam tawm sai thiab raug nqi kom zoo.
- Versatility: Muaj peev xwm luam tawm ntawm ntau hom ntawv ntau thiab ntau thiab tsawg, ua kom haum rau ntau yam kev siv.
- Xim xwm yeem: Advanced xim tswj xyuas kom ntseeg tau tias cov xim nyob twj ywm raws li cov luam tawm.
Kev Txij Nkawm thiab Kev Txiav Txim Siab
Kev ua haujlwm 4 xim offset tshuab luam ntawv yuav tsum tau cov neeg ua haujlwm txawj los tswj cov number cask ntawm number case ntawm number case ntawm number case ntawm number cask thiab dej, kev saib xyuas npe, thiab ua kev txij nkawm. Kev tu ib txwm ntawm chais, daim hlau, thiab lwm yam yog qhov tseem ceeb kom muab cov ntawv luam zoo thiab txuas lub TSHUAB lifespan.
