Yam Tseem Ceeb rau Kev Tswj Cov Ntawv Luam Ntawv Zoo
Muaj plaub yam kev tswj hwm rau cov khoom luam tawm: xim, gradation, clarity, thiab sib xws.
Xim:Xim yog lub hauv paus ntawm cov khoom zoo, ncaj qha txiav txim siab nws qhov zoo tshaj plaws. Kev tswj xim lossis kev tswj hwm yog ib qho tseem ceeb uas tau kawm thiab tshuaj xyuas los ntawm cov kws tshaj lij luam ntawv.
Gradation:Gradation yog hais txog cov xim gradients pom hauv daim duab. Nws tsim lub hauv paus rau kev hloov xim kom raug.
Clarity:Clarity yog hais txog lub meej ntawm cov duab cov ntsiab lus, encompassing lub clarity ntawm fine-level cov ntsiab lus, lub sharpness ntawm cov duab contours, thiab clarity ntawm cov duab cov ntsiab lus.
Kev sib raug zoo:Consistency, los yog uniformity, muaj ob yam. Ua ntej, nws hais txog qhov sib xws ntawm tus number case kom muaj nuj nqis nyob rau hauv ntau qhov sib txawv ntawm tib batch, feem ntau ntsuas los ntawm qhov sib xws ntawm cov khoom ntsug thiab kab rov tav ntawm cov khoom luam tawm. Qhov no qhia txog kev ruaj ntseg ntawm qhov sib txawv ntawm cov khoom luam tawm uas tsim nyob rau tib lub sijhawm. Qhov thib ob, nws hais txog qhov sib xws ntawm qhov ntom ntom ntawm tib qho ntawm cov khoom sib txawv, uas qhia txog kev ruaj ntseg ntawm cov xovxwm luam ntawv.
Rau cov khoom luam tawm, tswj cov plaub yam no-xim, gradation, clarity, thiab sib xws-ua kom zoo luam ntawv.
Cov txheej txheem tswj kev luam ntawv zoo
Ib txoj hauv kev ntawm kev tswj xyuas kev luam ntawv yog kev siv cov khoom siv hluav taws xob, cov khoom siv ntsuas, cov tuav tswj, thiab cov kauj ruam, ua ke nrog cov cuab yeej ntsuas thiab cov kab kos, rau kev tshawb fawb kom muaj nuj nqis ntawm kev luam ntawv zoo (xws li ob qho tib si luam tawm cov khoom zoo thiab cov tshuab luam ntawv zoo) . Ntau lub tebchaws siv cov tshuab sib txawv, xws li GATF system hauv Tebchaws Meskas, Bruennel system hauv Switzerland, FOGRA system hauv Tebchaws Yelemees, thiab Gracol system.
Feem ntau siv cov cuab yeej tshawb nrhiav hauv kev luam ntawv suav nrog cov teeb liab bar, ntsuas ntsuas, tswj tuav, thiab cov kauj ruam wedges. Cov kab hluav taws xob feem ntau yog siv los ntsuas qhov muag pom, qhia cov ntaub ntawv hais txog qhov zoo ntawm cov khoom luam tawm. Cov kab ntsuas yog cov cim cim ntau yam tshwj xeeb rau kev ntsuas qhov ntsuas kom pom thiab ntsuas ntsuas. Cov tuav tswj tau muab cov kev ntsuam xyuas pom thiab kev ntsuam xyuas ntawm cov teeb liab thiab cov kab ntsuas. Cov kauj ruam wedges muaj qhov sib npaug-density los yog dot kauj ruam wedges siv los tswj cov phaj raug thiab luam ntawv zoo.
Hauv ib puag ncig digital, kev tswj xim yog qhov tseem ceeb. Nws koom nrog kev sib kis ntawm cov ntaub ntawv xim hla ntau yam khoom siv thiab xov xwm. Lub International Color Consortium (ICC) tau tsim ib tus qauv, ICC Profile, los piav txog cov xim ua haujlwm ntawm cov khoom siv. Cov txheej txheem tswj xim, siv ICC Profile cov yam ntxwv cov ntaub ntawv, pab txhawb kev tsim cov xim sib xws thoob plaws ntau yam khoom siv thiab cov ntaub ntawv.
Hauv kev ua haujlwm digital, kev xa cov ntaub ntawv thiab kev tswj hwm yog qhov tseem ceeb vim tias muaj cov ntaub ntawv ntau ntxiv. Qhib Prepress Interface (OPI) thiab Desktop Xim Sib cais (DCS) cov lus qhia tshwj xeeb tau tsim los rau kev tswj hwm cov ntaub ntawv hauv prepress, optimizing cov ntaub ntawv xa mus thiab kev tswj hwm hauv internet.
Kev pov thawj digital, tshwj xeeb nrog kev nce qib hauv Raster Image Processors (RIPs), tau dhau los ua ib feem tseem ceeb ntawm cov txheej txheem luam tawm. RIPs pab "rip ib zaug, tso zis ntau zaus," kom ntseeg tau qhov sib xws ntawm cov ntaub ntawv pov thawj thiab cov ntaub ntawv siv rau kev luam ntawv.
Cov thev naus laus zis tshuaj xyuas online, suav nrog CCD lub koob yees duab, tau dhau los ua ntau yam. Cov thev naus laus zis no tso cai rau kev soj ntsuam tas li ntawm cov khoom luam tawm ntawm cov kab ntau lawm, muab cov lus tawm tswv yim tiag tiag rau kev tswj hwm thiab kev txhim kho kom zoo. Kev tshuaj xyuas online tuaj yeem suav nrog kev tshawb pom xim, kev tshuaj xyuas kev teeb tsa, kev txheeb xyuas tus cwj pwm, kev sau npe, nrog rau kev kuaj pom qhov tsis xws luag xws li luam tawm tsis raug, overprints, thiab daim phiaj qias neeg.
