Ufuna ukubonisa umbala opapashiweyo kwiscreen? Ukuguqula i-CMYK uye kwi-RGB kukunika into ekhanyayo efana nepesenti zakho ze-inki — amaxabiso awakuboniswa yimonitha, imockup okanye iphepha lewebhu.
Indlela yokuguqula CMYK uye ku-RGB
- Guqula onke amaphesenti amane abe zi-fracsheni phakathi kwe-0 kunye ne-1.
- Faka icomponent ye-key kuqala: wonke umjelo usokoliswa ngu (1 − K).
- Bala R = 255 × (1 − C) × (1 − K), G = 255 × (1 − M) × (1 − K) kunye ne B = 255 × (1 − Y) × (1 − K).
- Jikeleza wonke umjelo ube linani elipheleleyo phakathi kwe-0 kunye ne-255.
Umzekelo osebenzayo
Sisonjululo nje. Isikrini sinokubonisa imibala emininzi kunoko i-inki inokuyivelisa, ngoko isiphumo se-RGB sihlala sibonakala sikhanyayo ngakumbi kwaye sinesaturation engakumbi kunento eprintiweyo.
CMYK kunye ne-RGB zichazwe
Yintoni i-CMYK?
I-CMYK ngumzekelo we-inki ezine osetyenziswa kuphrinto: cyan, magenta, yellow kunye ne-key (black), nganye njengipesenti ukusuka ku-0 ukuya ku-100. I-inki isusa ukukhanya endaweni yokukukhupha, ngoko ke i-CMYK ibamba imibala embalwa kune-skrini — yiyo loo nto imibala ekhanyayo yesikrini idla ngokubonakala ingacacanga xa iphrintiwe.
- Isyntax:
- cmyk(C%, M%, Y%, K%)
- Ububanzi:
- 0–100% per ink
- Ilungele kakhulu:
- ukuphrinta, ukupakisha, imisebenzi yerhafu-press elungele umsebenzi
Yintoni i-RGB?
I-RGB ichaza umbala njengeziteshi ezintathu zokukhanya — red, green kunye ne-blue — nganye ukusuka ku-0 ukuya ku-255. Ifana nendlela izikrini ezisebenza ngayo: zonke ezintathu kwi-255 zinika umhlophe, zonke kwi-0 zinika omnyama. I-RGB lulungelelo xa kufuneka ubale nombala, kwaye i-rgba() yongeza ukungabonakali ngaphezu kwayo.
- Isyntax:
- rgb(R, G, B)
- Ububanzi:
- 0–255 per channel
- Ilungele kakhulu:
- ikhowudi, canvas, ukungabonakali nge rgba()
