Yuav Ua Li Cas CTP Phaj?

Tsim lub Computer-to-Plate (CTP) phaj muaj ntau txoj hauv kev uas hloov cov duab kos duab lossis cov duab rau hauv lub cev luam ntawv phaj siv hauv offset printing. CTP thev naus laus zis tau hloov pauv kev lag luam luam tawm los ntawm kev tshem tawm qhov xav tau ntawm cov txheej txheem ua yeeb yaj kiab raws li kev ua yeeb yaj kiab, ua kom cov haujlwm ua haujlwm zoo, txo lub sijhawm ntau lawm, thiab txhim kho kev luam ntawv zoo. Nov yog ib qho kev piav qhia ntawm cov kauj ruam koom nrog hauv kev ua CTP phaj:

Kev npaj ntawm Digital Artwork: Cov txheej txheem pib nrog kev tsim lossis tau txais cov duab kos duab lossis cov duab los luam tawm. Cov duab kos duab no yuav suav nrog cov ntawv nyeem, duab, thiab cov duab, thiab nws feem ntau yog tsim los siv cov duab tsim software xws li Adobe Illustrator, Photoshop, lossis InDesign.

Xim sib cais: Yog tias daim duab kos duab muaj ntau xim, nws yuav tsum tau muab cais ua cov xim ntawm tus kheej (cyan, magenta, daj, thiab dub) siv software tshwj xeeb. Cov txheej txheem no, hu ua kev sib cais xim, tsim cov ntaub ntawv sib cais rau txhua qhov xim channel, uas yuav raug siv los nthuav tawm cov phaj sib xws thaum lub phaj tsim.

Phaj Layout: Thaum cov xim sib cais tiav lawm, cov xim ntawm tus kheej raug teeb tsa rau hauv ib lub phaj layout. Lub layout qhia txog txoj hauj lwm thiab kev taw qhia ntawm txhua xim ntawm lub phaj luam ntawv, kom ntseeg tau tias kev sau npe raug thiab xim sib dhos thaum luam ntawv.

CTP Imaging: Cov ntaub ntawv layout ntawm lub phaj yuav raug xa mus rau CTP imaging device. CTP imager siv lasers los nthuav tawm lub teeb-sensitive txheej rau saum npoo ntawm lub phaj luam ntawv, tsim cov duab kos duab lossis cov duab los luam tawm. Cov txheej txheem raug raug tswj los ntawm cov ntaub ntawv digital, kom ntseeg tau qhov tseeb ntawm cov khoom qub qub.

Phaj Development: Tom qab raug, cov ntawv luam ntawv tau dhau los ua cov txheej txheem kev txhim kho kom tshem tawm cov chaw tsis pom kev ntawm lub teeb-sensitive txheej. Cov txheej txheem no feem ntau yog immersing lub phaj nyob rau hauv ib qho kev daws teeb meem los yog siv cov kev daws teeb meem uas siv ib chav tsim tawm. Tus tsim tawm cov tshuaj chemically reacts nrog rau qhov chaw ntawm lub phaj, tawm hauv qab daim duab yuav tsum luam tawm.

Phaj tiav: Thaum lub phaj tsim, nws yuav dhau los ua cov kauj ruam ntxiv los txhim kho nws cov kev ua tau zoo thiab ua haujlwm ntev. Qhov no tej zaum yuav muaj xws li kev kho mob xws li ci los yog pos hniav kom stabilize cov duab thiab tiv thaiv lub phaj nto ntawm hnav thiab tsim kua muag thaum luam ntawv.

Kev Tswj Xyuas Zoo: Thoob plaws hauv cov txheej txheem ua phaj, kev tswj xyuas kev ua tau zoo yog siv los xyuas kom meej tias cov phaj ua tau raws li qhov xav tau tshwj xeeb rau kev luam ntawv zoo thiab raug. Qhov no yuav suav nrog kev tshuaj xyuas qhov muag ntawm daim hlau, ntsuas qhov tseem ceeb tsis xws li dot loj thiab qhov ntom ntom, thiab kuaj rau kev sau npe thiab kev sib dhos.

Phaj Mounting: Thaum cov phaj raug tsim thiab tshuaj xyuas, lawv tau muab tso rau hauv lub tshuab luam ntawv. Plate mounting muaj kev ruaj ntseg cov phaj rau ntawm lub phaj cylinders ntawm cov xovxwm, kom ntseeg tau tias kev tso npe thiab kev sib raug zoo nrog rau lwm yam khoom siv luam ntawv xws li daim pam thiab lub tog raj kheej impression.

Kev luam ntawv: Nrog rau daim hlau mounted thiab xovxwm teeb, txheej txheem luam ntawv tuaj yeem pib. Thaum lub sij hawm luam ntawv, tus number case raug xa mus los ntawm tus number case chais mus rau cov ntawv luam ntawv, qhov uas nws tau muab xa mus rau hauv lub tog raj kheej roj hmab thiab thaum kawg mus rau lub substrate (feem ntau yog daim ntawv los yog duab los qhia). Txhua lub phaj xim yog luam tawm ua ntu zus, nrog rau kev sau npe meej los tsim cov khoom luam tawm xim kawg.

Kev tu thiab tu: Tom qab luam ntawv, cov phiaj raug tshem tawm ntawm cov xovxwm thiab ntxuav kom tshem tawm cov kua nplaum los yog cov khib nyiab. Kev tu kom zoo thiab kev saib xyuas ntawm cov phiaj yog qhov tseem ceeb los ua kom lawv txoj sia nyob ntev thiab ua kom cov ntawv luam zoo sib xws hauv kev luam tawm yav tom ntej.
