Cov Ntawv Luam Ntawv Ntim Box Cov khoom siv tseem ceeb siv ua ntej luam ntawv digital yog dab tsi?

Cov cuab yeej tseem ceeb ntawm digital prepress suav nrog cov duab nkag, ua thiab cov khoom siv tso tawm.

Dab tsi yog cov khoom siv digital prepress duab input?

Cov khoom siv tseem ceeb yog Scanner, uas yog siv los hloov cov duab, slides, lossis cov ntawv sau rau hauv cov ntaub ntawv digital. Nws tuaj yeem muab faib ua ob pawg: platform scanning tshuab thiab nruas scanning tshuab. Tus thawj thav duab ntawm lub platform scanning tshuab yog tiaj tus, compact qauv, thiab CCD (tus nqi-coupled ntaus ntawv) yog siv raws li rhiab tivthaiv; Tus thawj thav duab ntawm lub nruas scanner yog pob tshab acrylic nruas, uas muaj ib tug complex qauv thiab siv PMT (photoelectric zaus doubler) raws li ib tug rhiab tivthaiv.

Nrog rau kev txhim kho ntawm CCD thev naus laus zis, tam sim no muaj ntau yam ntawm cov platform scanners ntawm kev ua lag luam los ntawm tus nqi qis dub thiab dawb scanners rau cov nqi siab tshaj plaws xim scanners. Cov kws tshaj lij platform scanners feem ntau pheej yig dua li cov tshuab luam ntawv nruas, tab sis lawv tuaj yeem tau txais qhov zoo sib xws thaum luam.

Dab tsi yog cov khoom siv digital prepress processing?

ComputerSystems feem ntau yog cov tshuab computer, uas muaj ob hom Macintosh thiab PC. Txawm hais tias koj xaiv lub khoos phis tawj twg, lub processor yuav tsum ceev tshaj plaws. Koj tuaj yeem txiav txim siab xaiv lub tshuab dual-CPU txhawm rau ua kom tiav. MAC tuaj yeem xaiv G4 lossis G5, PC yuav tsum xaiv P4 lossis siab dua, thiab ua hauv USB chaw nres nkoj; Tsawg kawg yog 1GB ntawm RAM, tus saib yuav tsum zoo, lub hard disk drive yuav tsum siab npaum li sai tau, thiab cov add-on DVD, MO, UPS, DiskArray thiab lwm yam khoom siv ntxiv yuav tsum ua kom tiav.

Tsis tas li ntawd, RIP (Raster Image Processor) yog siv los hloov cov lus piav qhia nplooj ntawv (PDL), xws li PostScript, mus rau hauv lub teeb liab los tswj cov khoom tso tawm, kom cov khoom tso tawm tuaj yeem tso tawm cov ntaub ntawv raws li cov lus piav qhia ntawm nplooj ntawv. lus piav qhia, los ntawm kev hloov cov ntaub ntawv mus rau ib qho point hom, thiab ces tsav lub tso zis ntaus ntawv. Ib daim duab yog tsim los ntawm kev ci ntsa iab ntawm lub laser ntawm daim ntawv tsis zoo lossis cov duab thaij duab hauv daim ntawv ntawm lub laser point. Feem ntau, RIP tuaj yeem muab faib ua hardware RIP thiab software RIP. Cov khoom tso zis tuaj yeem ua tau ntau yam xim lossis xim dub thiab dawb laser, inkjet, thermal hloov lossis thermal sublimation tshuab luam ntawv, nrog rau phototypesetters, zoo duab recorders, thiab lwm yam. PostScript tau ua cov ntaub ntawv tso tawm tam sim no.

Hardware RIP: Qhov kev pab cuam RIP khaws cia hauv ROM ntawm lub tshuab xam zauv, tshwj xeeb yog siv los cuam tshuam nrog ntau cov ntaub ntawv nyuaj. Nws cov cuab yeej kho vajtse zoo ib yam li lub tshuab xam zauv, nruab nrog CPU, muaj peev xwm loj RAM, ntab taw tes lej lej, dot generator acceleration card, hard disk drive (khoom Suav thiab Askiv fonts), thiab lwm yam. Tag nrho cov khoom siv RIP architecture tshwj xeeb yog siv. los ua haujlwm RIP.

Software RIP: Software RIP yog ib qho kev pab cuam uas tuaj yeem ua tiav ntawm lub hom phiaj dav dav (xws li cov khoos phis tawj tus kheej, Macs, thiab SUN computers). Nws yog khaws cia rau hauv lub laij lej li software. Zoo li cov ntawv thov zoo tib yam, nws raug tua thaum RIP yuav tsum ua tiav. Software RIP thiab hardware RIP muaj tib lub zog. Nyob rau tib lub sijhawm, kho vajtse RIP yuav nrawm dua li software RIP, tab sis? Nrog rau kev nrawm ntawm kev ua haujlwm ceev ntawm tus kheej lub khoos phis tawj thiab kev poob qis ntawm tus nqi, software RIP muaj cov yam ntxwv ntawm "upgradability, tsis tshua muaj nqi", uas txawv ntawm hardware RIP. Yog lawm, kuv ntseeg tias RIP yuav muaj kev lag luam loj heev yav tom ntej.
