CTP yog dab tsi?
Oct 28, 2022
Nyob rau hauv cov txheej txheem Offset luam ntawv cov txheej txheem ntawm kev cai lub thawv, cov ntawv luam tawm yog tso tawm rau cov duab thaij duab ua ntej, tom qab ntawv luam ntawv phaj (tsuas yog PS phaj) yog tsim. Yog li ntawd, lub tshuab imaging no tseem hu ua CTF, computer rau zaj duab xis. Txawm li cas los xij, tej yam txawv heev tam sim no. Hauv cov chaw luam ntawv niaj hnub no, cov duab kos duab, feem ntau hauv PDF hom tsim los ntawm Adobe Photoshop, Adobe Illustrator, Adobe Indsign thiab lwm yam duab layout daim ntawv thov raug tso tawm ncaj qha mus rau lub phaj luam ntawv. Thiab qhov tech no hu ua CTP.
CTP Technology
CTP thev naus laus zis txawv nrog hom kev tsim kho ntawm cov duab kos duab thiab lub teeb ci siv los nthuav tawm cov phaj saum npoo. Nyob rau hauv cov nqe lus ntawm imagesetter, muaj peb yam sib txawv: internal nruas, sab nraud nruas thiab tiaj-txaj imagesetters. Thiab lub teeb siv los nthuav tawm cov ntawv luam ntawv yog cov teeb ci ultraviolet thiab laser diodes. Lub wavelength thiab lub zog ntawm lub laser diodes nyob ntawm seb hom phaj siv.
CTP Phaj Qeb
Feem ntau muaj 3 hom: Photopolymer CTP daim hlau, Nyiaj Halogan CTP daim hlau, thiab cov phaj kub.
Qhov zoo ntawm CTP Phaj
CTP muaj ntau qhov zoo dua li cov pa platemaking. Nyob rau hauv CTP, ib tiam (hloov cov duab zaj duab xis mus rau lub phaj luam ntawv) raug tshem tawm los ntawm cov txheej txheem luam ntawv (tso tawm qhov xav tau ntawm cov yeeb yaj kiab thiab cov tshuaj tsim tawm), ua kom pom tseeb thiab nthuav dav. CTP zam kev poob qis hauv qhov zoo uas yuav tshwm sim thaum ua cov yeeb yaj kiab, suav nrog khawb hauv zaj duab xis, thiab qhov txawv ntawm qhov raug. Ib qho imagesetter feem ntau muaj qhov tseeb ntawm qhov ntxiv /-2 feem pua . Cov phaj yog tsim nyob rau hauv tsawg lub sij hawm, zoo ib yam, thiab ntawm tus nqi qis. CTP tseem tuaj yeem txhim kho kev sau npe thiab cov duab-rau-ntug rov ua dua li cov txheej txheem ib txwm muaj.
Hauv CTP, cov xov xwm tau sau npe (tsau nyob rau hauv txoj hauj lwm meej) nyob rau hauv lub platesetter thaum lub sij hawm imaging, thiab tsis cia siab rau ib tug nyias muaj nyias tus pin daim phiaj, ib yam li cov ntaub ntawv nrog zaj duab xis. Qhov tsis xws luag vim muaj plua plav, khawb lossis lwm yam khoom cuav raug txo kom tsawg.
CTP tshuab tuaj yeem ua kom cov phaj tsim tawm ntau. Platesetters rau kev tsim cov ntawv xov xwm tuaj yeem tso tawm mus txog 300 12-inch (300 mm) daim hlau ib teev ntawm 1270 DPI (dots per inch), whilst rau kev lag luam daim ntawv thov CTP system tuaj yeem tso tawm 60 B1 daim hlau ntawm 2400 DPI rau cov lus txiav txim siab dua.
Cov duab me me uas feem ntau tsim 1 lossis 2 xim tso zis tuaj yeem siv txhua yam los ntawm lub tshuab luam ntawv laser, rau qhov tsis zoo / tsawg ntim, mus txog qib siab-kawg platesetter kom zoo dua thiab ntim.
Disadvantage ntawm CTP Phaj
Txwv rau cov hom ntawv digital. CTP cov khoom tsim tawm xav kom lub hauv paus rau cov ntawv luam tawm nrog rau kev tswj hwm, yog digital.
Remaking ntawm daim hlau. Yog tias vim li cas CTP phaj puas lawm, yog tias muaj qhov yuam kev tshwm sim thaum nws raug ripped los yog ib yam dab tsi yuav tsum tau kho tom qab lub phaj raug, yuav tsum tau tsim ib tug tshiab, imposed phaj.
CTP Tech hauv Deprintedbox
Deprintedbox siv lub khoos phis tawj tshiab rau Plate thev naus laus zis, txuag lub sijhawm thiab nyiaj txiag thiab txhim kho kev luam ntawv zoo.
Faster Production Cycles CTP tshem tawm cov kauj ruam ntawm lub voj voog ntau lawm. Txawm tias nyob rau hauv Computer to Film (CTF) workflow nws tuaj yeem ua tsib kauj ruam los ntawm kev muaj daim ntawv theej rau hauv daim ntawv mus rau nws daim duab rau ntawm lub phaj. Hauv CTP txheej txheem plaub ntawm cov kauj ruam no raug tshem tawm tag nrho. Txhua kauj ruam tshem tawm los ntawm cov txheej txheem txo lub sij hawm tag nrho yuav tsum tau txais daim hlau los nias, tau txais txoj hauj lwm rau koj sai dua.
Tus nqi luam ntawv qis dua CTP tshem tawm qhov xav tau ntawm zaj duab xis los ntawm kev thaij duab nplooj ntawv ncaj qha los ntawm lub khoos phis tawj mus rau lub phaj luam ntawv, uas, ua kom lub voj voog luv luv thiab tuaj yeem txuag cov nqi khoom thaum kawg txuag koj cov nyiaj.
Sharper Print Quality CTP tso cai rau cov tshuab luam ntawv luam tawm kom huv si thiab cov duab crisper los ntawm kev tshem tawm cov dot nce hauv cov txheej txheem prepress. Hauv CTP workflow, thawj tiam dots yog duab rau lub phaj tshem tawm dot nce hauv prepress. Qhov no ua rau cov xovxwm muaj peev xwm ntau dua rau kev luam ntawv ntau dua number case uas ua rau cov xim nplua nuj, zoo dua saturated.
Kev sau npe zoo dua CTP tsis suav nrog kev siv cov yeeb yaj kiab tsis zoo lossis qhov zoo. CTP daim hlau yog cov duab ntawm cov khoom siv phaj siab zoo ntawm cov khoom siv txhuas uas tiv taus qhov kub thiab av noo. Txawm hais tias lub khoos phis tawj raug kaw rau zaj duab xis ua haujlwm tsis tuaj yeem muab qhov tseeb thiab ruaj khov ntawm kev sau npe uas CTP system tuaj yeem muab tau.
