Peb tau tham txog qhov yuav tsum tau muaj los ntawm ib qho ntawm lawv cov neeg muag khoom uas tau hu rau cov ntaub ntawv duab digital kom muab los ua, lossis hloov mus rau, CMYK. Yog tias qhov kev hloov pauv no tsis ua tiav lawm, cov duab tshwm sim yuav muaj cov xim av nkos thiab tsis muaj vibrancy uas tuaj yeem cuam tshuam tsis zoo rau koj lub hom phiaj.

CMYK yog ib lo lus siv dav hauv kev lag luam duab kos duab thiab tseem hu ua "xim puv." Txoj kev luam ntawv no siv cov txheej txheem uas txhua tus cwj mem xim luam tawm nrog cov qauv tshwj xeeb, txhua qhov sib tshooj los tsim cov xim sib txawv. Nyob rau hauv ib tug subtractive xim spectrum, qhov ntau xim koj overlap, lub darker lub resulting xim. Peb ob lub qhov muag txhais cov xim spectrum no raws li cov duab thiab cov lus ntawm daim ntawv lossis cov ntawv luam tawm.
Qhov koj pom ntawm koj lub khoos phis tawj saib yuav ua tsis tau nrog plaub-xim txheej txheem luam ntawv.
RGB yog ib qho ntxiv xim spectrum. Feem ntau, txhua daim duab tso tawm ntawm lub monitor lossis lub vijtsam digital yuav raug tsim hauv RGB.

Thaum peb tab tom npaj artwork rau peb cov neeg siv khoom, ua tib zoo saib xyuas thaum hloov cov duab kos los ntawm RGB rau CMYK. Hauv qhov piv txwv saum toj no, koj tuaj yeem pom yuav ua li cas RGB cov duab uas muaj cov xim ci tuaj yeem pom cov xim tsis xav hloov thaum hloov mus rau CMYK.
