Cov tuam txhab luam ntawv tseem tuaj yeem ua kom qhov kev pib ntawm CTP los ntawm kev ua haujlwm nrog cov tuam txhab prepress thiab cov chaw tso tawm.
Cov teeb meem thiab cov teeb meem uas tau ntsib hauv kev siv CTP
Rau lub tuam txhab luam ntawv tus thawj coj, qhov kev saws me nyuam ntawm CTP system yuav ntsib ib co teeb meem muaj feem, nrog rau kev xaiv tus neeg xa khoom. Vim tias CTP yog lub sij hawm ntev, tus tswv lag luam yuav tsum tau nqis peev lub nqi ntawm cov khoom siv los mus tsim cov kev siv tshuab no, yog li xaiv tus CTP ua lag luam txhais tau tias tsis yog xaiv ib yam khoom, tab sis xaiv ib tug khub. Muaj ntau tus neeg muag khoom muaj plates, tab sis cov khoom thiab consumables siv lwm cov tuam txhab. Qhov koj xav tau yog ib qhov chaw muab kev pabcuam uas ua haujlwm nrog haujlwm ua haujlwm pem hauv ntej, platesetter, phaj thiab yaug dej.
Plate thiab imaging technology yog lwm qhov teeb meem uas yuav tsum tau xav txog hauv kev siv CTP systems. Tam sim no muaj 4 phaj luam ntawv yees xaiv los ntawm: photosensitive resin daim hlau (xws li N90A), nyiaj phom nyiaj nyiaj (xws li Lithostar thiab Silverlith), cov pa phaj los ntawm thawj ob, thiab thaum kawg thermal daim hlau, tag nrho rau cov neeg siv. Tuaj kom zoo rau kev luam ntawv.
Cov teeb meem pov thawj hauv teeb meem hauv CTP tau ua ib qho kev txhawj xeeb loj rau cov luam ntawv. Vim tias qhov kev hloov no yuav siv sij hawm, luam cov neeg lag luam yuav tsum siv sij hawm los kawm qhov kev sib piv xim, thiab cov neeg muas zaub yuav tsum siv sij hawm los hloov thiab ntseeg tau cov ntawv pov thawj. Nws muaj ob hom xim nyob rau hauv cov xim: ib nrab ntawm ib nrab thiab tsis tu ncua lub suab pov thawj. Txhua yam nws muaj nws qhov zoo thiab qhov tsis zoo, tab sis tom qab hloov thiab tswj, nws tuaj yeem tsim cov xim zoo. Agfa ntseeg tias txawm tias halftone proofing tau nws qhov zoo, nws yog kim (ib puas thiab peb puas txhiab daus las), thiab nruam lub suab proofing muaj cov yam ntxwv ntawm txuag nqi luam thiab ua tau yooj yim mus use, yog li nws yuav hloov halftone. Ntawv pov thawj. Agfa muaj lub SelectProof proofing program uas xa ntawv PostScript los sis PDF rau txhua qhov kev xeem ntawv, thiab qhov kev tswj tuav ICC kom zoo ib yam. Ntxiv nrog rau cov xim tiv thaiv, nplooj ntawv thiab cov pab pawg neeg pov thawj tseem ceeb, thiab cov luam ntawv yuav tsum xav txog nws zoo zoo. Vim hais tias CTP yog ib txoj haujlwm ntau, nws yuav tsum tau siv ob qho txuj ci thiab kev txhawb nqa software thiab khoom kho. Muaj ntau cov tuam txhab uas siv cov kab CTP kom tau ib tus nplua nuj rov qab los ntawm peev feem ntau yuav ua tiav vim lawv muaj qhov kev txawj ntse thiab kev ua haujlwm ua haujlwm. Yog li ntawd, nws yog ib qho tseem ceeb rau kev cob qhia koj cov neeg ua haujlwm thiab txais yuav ib txoj hauv kev tsim cov khoom tsim los txo cov kev ua yuam kev thiab ua kom ntau ntxiv. Yog li, cov tshuab luam ntawv uas xav kom ua lag luam hauv CTP yuav tsum muaj kev nkag siab zoo txog lawv lub lag luam cov khoom tsim tau thiab cov nyiaj tau. Kev ntsuam xyuas txog kev ua haujlwm tam sim no thiab kev txheeb xyuas ntawm cov theem kev ua haujlwm ntawm cov neeg ua haujlwm yog qhov pib.
Lub ntsiab lus ntawm CTP
CTP yog tsim rau ntau yam kev siv, thiab nws yog qhov tshwj xeeb tshaj yog tsim rau kev ua haujlwm raug kaw uas muab cov kev kho / tsim ib feem ntawm lub hauv ntej kawg nrog ntau qhov kawg ntawm tus nraub qaum kawg. Yog li no, CTP yog tsim tshwj xeeb rau cov tshuab luam ntawv uas siv digital hom ntaub ntawv, xws li daim ntawv luam tawm, nyiaj luam ntawv, ntim printing, thiab kev lag luam luam tawm. Rau cov ntawv xov xwm tshaj tawm, cov ntawv xov xwm uas siv tag nrho digital cov txheej txheem editing, los yog cov ntsiab lus meej meej, yuav siv tau rau CTP. Magazine Publishing yog ib daim ntawv teev npe nyuaj rau CTP vim nws yog cov yeeb yaj kiab tawm los ntawm cov neeg siv khoom. Lwm cov lag luam me me thiab cov lag luam me kuj tsis yooj yim rau kev txais CTP dav vim yog cov peev txheej loj thiab cov ntawv tsis txaus ua haujlwm. Tej zaum lawv yuav xav siv kev siv nyiaj txiag CTP raws li lub phaj tshuaj polyester, xws li Agfa's ChoicePlate. Nyob ntawm ntau theem ntawm "Digital Highway", yuav muaj kev sib txawv ntawm qhov system.
