RGB waa isku-dar iftiin (additive) halka CMYK uu yahay ka-jarid (subtractive) oo ka samaysan khad. Beddelidda labadaba waa talaabada naqshad kasta oo shaashad ah ka hor inta aan la daabicin.
Sida RGB ilaa CMYK beddelku u shaqeeyo
- Akhri R, G iyo B sida qiyamka sRGB ee u dhexeeya 0 iyo 255.
- Ka raadi midabka profile-ka Coated FOGRA39, profile-ka ICC ee caadiga ah ee warqadda la dahaadhay ee Yurub.
- Isticmaal habka qiyaasta midabka ee xiriirka ah iyo magdhowga dhibicda madow, si caddaanku u ahaado caddaanka warqadda, madowna u beddelmo khadka ugu madow ee makiinadda daabacaadda ay daabici karto.
- Beddel dhammaan afarta qiime boqolleyda u dhaxaysa 0 iyo 100.
Tusaale shaqeeyay
Tani waxay isticmaalaysaa profile-ka caadiga ah ee Coated FOGRA39. Matbacadaha waxay isticmaalaan profile-yadooda ICC iyo xadadka khadka, sidaas darteed profile-yada CMYK kale (tusaale ahaan ka matbacaddaada) waxay siiyaan tirooyin kala duwan. U qaado natiijada tixraac adag, ma aha kala-soocid diyaar u ah daabacaadda.
RGB iyo CMYK sharaxan
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.
- Nidaamka qoraalka:
- rgb(R, G, B)
- Xadka:
- 0–255 per channel
- Ku habboon:
- koodh, canvas, hufnaan leh rgba()
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.
- Nidaamka qoraalka:
- cmyk(C%, M%, Y%, K%)
- Xadka:
- 0–100% per ink
- Ku habboon:
- daabac, baakadaha, shaqo diyaar u ah press
