Ma u baahan tahay inaad midab daabacan ku muujiso shaashadda? Beddelidda CMYK ilaa RGB waxay ku siisaa u dhigma iftiinka ee boqolleyda khadkaaga — qiimayaasha uu monitorka, mockup ama bogga webku runtii soo bandhigi karo.
Sida CMYK ilaa RGB beddelku u shaqeeyo
- Beddel dhammaan boqolleyda afarta kanaal jajabyo u dhaxeeya 0 iyo 1.
- Marka hore adeegso qaybta key: kanaal kasta waxaa lagu miisaamaa (1 − K).
- Xisaabi R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K) iyo B = 255 × (1 − Y) × (1 − K).
- Rogo kanaal kasta ilaa lambar buuxa oo u dhexeeya 0 iyo 255.
Tusaale shaqeeyay
Qiyaas. Shaashadu waxay muujin kartaa midabyo ka badan intii khadku soo saari karo, sidaas darteed natiijada RGB badanaa waxay u muuqataa mid dhalaal iyo saturation dheeraad ah leh marka loo eego daabacaadda.
CMYK iyo RGB sharaxan
Waa maxay CMYK?
CMYK waa moodelka afarta-ink oo loo isticmaalo daabacaadda: cyan, magenta, yellow iyo key (madow), midkiiba boqolkiiba 0 ilaa 100. Xarfaha ink-ka waxay ka jarayaan iftiin halkii ay ka sii dayn lahaayeen, sidaa darteed CMYK wuxuu daboolaa midabyo ka yar shaashadda — taasoo ah sababta midabada dhalaalaya ee shaashadda ay mararka qaarkood u muuqdaan kuwo liita marka la daabaco.

Waa maxay RGB?
RGB wuxuu sharraxayaa midab sida saddex kanaal oo iftiin ah — casaanka, cagaaran iyo buluug — midkiiba 0 ilaa 255. Waxay ka tarjumaysaa sida shaashaduhu dhab ahaantii u shaqeeyaan: saddexduba marka ay 255 yihiin waxay bixiyaan caddaan, dhammaantood marka ay 0 yihiin waxay bixiyaan madow. RGB waa doorashada saxda marka aad u baahan tahay inaad xisaabiso midabka, waxaana rgba() ku darayaa hufnaan dheeraad ah.
