Muaj ntau cov qauv uas siv cov duab nraaj tsim los ntsuas qhov tseeb thiab piav qhia xim. RGB yog cov tseem ceeb tshaj vim tias nws yog qhov peb lub computer siv los tso saib cov ntawv nyeem thiab cov duab . Nws yog qhov tseem ceeb heev uas cov neeg tsim qauv nraaj to taub qhov txawv ntawm RGB thiab CMYK thiab cov chaw ua haujlwm xws li sRGB thiab Adobe RGB. Cov no yuav txiav txim siab li cas tus neeg pom pom koj cov haujlwm tiav lawm.
RGB xim qauv qauv
RGB xim qauv yog raws li txoj kev xav hais tias tag nrho cov xim pom muaj peev xwm raug tsim los siv cov lus xub thawj xim xim liab, ntsuab, thiab xiav. Cov xim no yog hu ua 'thawj additives' vim hais tias thaum lawv sib koom ua ke sib npaug zos lawv tsim cov xim dawb. Thaum ob lossis peb leeg koom ua ke sib txawv, lwm cov xim yog tsim los.
Piv txwv, sib txuas cov xim liab thiab ntsuab hauv vaj huam sib luag ua rau xim daj, ntsuab thiab xiav tsim cyan, thiab xim liab thiab xiav tsim tau magenta. Cov qauv no xyov xim CMYK siv luam.
Thaum koj hloov tus nqi liab, ntsuab thiab xiav koj tuaj nrog cov xim tshiab. Cov kev sib txuas lus muab ib qho kev ua tsis tiav ntawm cov xim.
Tsis tas li ntawd xwb, thaum twg ib qho ntawm cov xim tseem ceeb no tsis tuaj, koj tau dub.
RGB xim nyob rau nraaj tsim
Tus qauv RGB yog ib qho tseem ceeb rau kev nraaj tsim vim nws siv rau hauv computer monitors . Qhov kev tshuaj ntsuam koj nyeem ntawv no heev ntawm kev siv cov xim ntxiv rau cov duab thiab cov ntawv nyeem. Yog vim li cas koj tus neeg tso cai rau koj los kho cov xim liab, ntsuab, thiab xim xiav thiab koj tus saib xyuas lub xim calibrator ntsuas cov ntxaij ntawm cov xim peb li thiab.
Yog li no, thaum tsim cov websites thiab lwm yam hauv kev ntsuam xyuas xws li kev nthuav tawm, tus qauv RGB siv vim hais tias qhov kawg khoom yog saib rau ntawm lub computer cov duab.
Yog tias, txawm li ntawd los, koj tab tom tsim cov ntawv luam tawm, koj yuav siv CMYK xim qauv. Thaum tsim ib qhov project uas yuav tau saib ob qho tib si ntawm kev tshuaj ntsuam thiab luam tawm, koj yuav tsum hloov daim luam luam mus rau CMYK.
Ntsis: Vim tias tag nrho cov sib txawv ntawm cov ntaub ntawv uas tsim tawm yuav tsum ua, nws yog qhov tseem ceeb heev uas koj tsim thiab muab npe rau koj cov ntaub ntawv rau lawv lub hom phiaj. Npaj ib lub tswv yim cov ntaub ntawv mus rau lwm cov ntawv sau rau cov ntawv luam tawm thiab kev siv web thiab ntxiv cov yeeb yam xws li '-CMYK' rau tom kawg ntawm cov ntaub ntawv tsim nyog. Qhov no yuav ua rau koj txoj hauj lwm yooj yim dua thaum koj xav nrhiav cov ntaub ntawv rau koj tus neeg.
Hom mob RGB xim ua haujlwm
Tsis pub dhau RGB cov qauv yog txawv xim qhov chaw hu ua 'chaw ua haujlwm.' Ob feem ntau yog siv sRGB thiab Adobe RGB. Thaum ua hauj lwm hauv ib qho software program xws li Adobe Photoshop lossis Illustrator, koj tuaj yeem xaiv qhov chaw ua haujlwm.
- sRGB: Qhov chaw sRGB zoo tshaj yog siv thaum tsim kom muaj lub vev xaib, vim nws yog lub tshuab computer ntau tshaj plaws.
- Adobe RGB: Adobe RGB qhov chaw muaj ntau qhov xim xaiv uas tsis muaj nyob rau hauv qhov chaw sRGB, yog li nws yog qhov zoo tshaj plaws los siv thaum tsim tawm rau kev sau. Nws kuj raug pom zoo rau kev siv duab nrog cov koob yees duab digital (xws li cov neeg siv khoom-theem) vim hais tias cov koob yees duab siab siv ntau zaus siv Adobe RGB qhov chaw.
Koj tuaj yeem khiav mus rau ib qho teeb meem nrog Adobe RGB dluab thaum lawv pom hauv ib lub vas sab. Daim duab yuav pom zoo rau hauv koj lub software, tiam sis yuav tshwm sim thiab tsis muaj cov xim vibrant rau ntawm qhov web page. Feem ntau, nws cuam tshuam cov xim xim xws li cov txiv kab ntxwv thiab cov xim liab feem ntau. Txhim kho qhov teeb meem no, tsuas yog hloov cov duab rau sRGB hauv Photoshop thiab txuag tau ib daim qauv uas tau tsim los siv rau kev siv web.
