Cov neeg tsim duab kos duab siv ntau yam qauv los ntsuas thiab piav qhia xim, nyob ntawm qhov nruab nrab. Cov uas tsim los saib ntawm cov ntxaij vab tshaus xws li khoos phis tawj thiab TV cia siab rau RGB (liab, ntsuab, xiav).
RGB Xim Qauv Basics
Tus qauv xim RGB yog raws li kev xav tias txhua qhov pom xim tuaj yeem tsim siv liab, ntsuab, thiab xiav. Cov xim no hu ua thawj additives vim hais tias, thaum sib xyaw ua ke, lawv tsim dawb. Thaum ob lossis peb ntawm lawv sib xyaw ua ke sib txawv, lwm cov xim raug tsim.
Piv txwv li, kev sib xyaw xim liab thiab ntsuab hauv qhov sib npaug ua rau daj; ntsuab thiab xiav tsim cyan; thiab liab thiab xiav tsim magenta. Cov qauv no tsim cov CMYK (cyan, magenta, daj, dub) xim siv hauv luam ntawv.
Hloov cov xim liab, ntsuab, thiab xiav, koj tuaj yeem tsim cov xim tsis muaj qhov kawg. Thaum ib qho ntawm cov xim tseem ceeb no tsis tshwm sim, koj tau txais dub.
Ib qho xim RGB tau nthuav tawm raws li peb tus lej hu ua hexadecimal triplet; txhua tus lej sib raug rau tus nqi liab, ntsuab, lossis xiav hauv qhov kev txiav txim, xws li 0 txog 255. Piv txwv li, rgb(255, 255, 255) ua rau dawb.
RGB Xim hauv Graphic Design
Lub vijtsam koj nyeem cov kab lus no yog siv cov xim ntxiv los tso saib cov duab thiab cov ntawv tsim hauv RGB qauv. Tias yog vim li cas koj lub monitor tso cai rau koj los kho cov xim liab, ntsuab, thiab xiav, thiab koj tus saib cov xim calibrator ntsuas cov ntxaij vab tshaus ntawm peb xim ib yam nkaus.
Yog tias, txawm li cas los xij, koj tab tom tsim luam tawm, koj yuav siv CMYK xim qauv. Thaum tsim ib qhov project uas yuav pom ob qho tib si ntawm lub vijtsam thiab luam tawm, koj yuav tsum tau hloov cov ntawv luam rau CMYK.
Raws li tus tsim qauv, koj yuav tsim tau ntau cov ntaub ntawv rau ntau yam xov xwm, yog li kev nyob ruaj khov yog qhov tseem ceeb. Txog qhov kawg, ntxiv cov ntsuas xws li "-CMYK" thiab "-RBG" rau koj cov npe thiab khaws cov folders kom huv si. Qhov no yuav ua rau koj txoj haujlwm yooj yim dua thaum koj xav nrhiav cov ntaub ntawv tshwj xeeb rau koj cov neeg siv khoom.
Hom RGB Xim Chaw Ua Haujlwm
Nrog rau tus qauv RGB yog cov xim sib txawv hu ua chaw ua haujlwm. Qhov ob feem ntau siv yog sRGB thiab Adobe RGB. Thaum ua haujlwm hauv software software xws li Adobe Photoshop lossis Illustrator, koj tuaj yeem xaiv qhov chaw ua haujlwm hauv.
- sRGB: Zoo tshaj thaum tsim lub vev xaib, apps, thiab lwm yam xov xwm digital.
- Adobe RGB: Muaj ntau cov xim xaiv uas tsis muaj nyob rau hauv qhov chaw sRGB, yog li nws zoo dua rau luam tawm thiab cov duab thaij nrog lub koob yees duab siab.
Adobe RGB cov duab tuaj yeem teeb meem ntawm lub vev xaib. Cov duab yuav zoo li amazing hauv koj lub software tab sis npub ntawm nplooj ntawv web. Feem ntau, qhov no cuam tshuam rau txiv kab ntxwv thiab liab ntau tshaj plaws. Txhawm rau txhim kho qhov teeb meem no, tsuas yog hloov cov duab rau sRGB hauv Photoshop thiab khaws ib daim ntawv theej uas tsim los siv lub vev xaib.
