Udinga ukukhipha umbala opapashwe esikrinini? Ukuguqula i-CMYK iye ku-RGB kukunikeza okufanayo okususelwe ekukhanyeni kweziphesenti ze-inki — amanani angaboniswa yi-monitor, i-mockup noma ikhasi lewebhu.
Indlela okuhunyushwa ngayo CMYK kuya ku-RGB
- Thatha amaphesenti amane njengezinga lenki yephrofayili ye-Coated FOGRA39.
- Funda umbala iphrofayili eyiphrinta kulowo mxube wenki, usebenzisa inhloso ye-colorimetric ehlobene nokunxephezelwa kwephoyinti elimnyama.
- Guqula lowo mbala ube yi-sRGB. Imibala esikrini esingeke siyibonise ishintshwa ngenani eliseduze kakhulu esingalibonisa.
- Gingqika isiteshi ngasinye ube inombolo ephelele phakathi kuka-0 no-255.
Isibonelo esisebenzayo
Umphumela we-RGB ukhombisa ukuthi lo mxube wenki ubukeka kanjani ephepheni elimbozwe ngephrofayili ejwayelekile ye-Coated FOGRA39. Amaphrofayili e-CMYK ahlukile (njengalawo avela esitolo sakho sokuphrinta) anikeza izinombolo ezihlukile, futhi into eyiphrintiwe ayikaze icwebe njengesikrini.
CMYK no-RGB kuchazwe
Iyini CMYK?
I-CMYK yimodeli yama-inki amane esetshenziswa ekuphrinteni: cyan, magenta, yellow kanye ne-key (black), ngakunye njengesibalo kusuka ku-0 kuya ku-100%. I-inki isusa ukukhanya esikhundleni sokukhipha, ngakho i-CMYK imboza imibala embalwa kunesikrini — yingakho imibala ekhanyayo yesikrini ivame ukubukeka iyinto ephansi uma iphrintiwe.
- Isakhiwo:
- cmyk(C%, M%, Y%, K%)
- Ibanga:
- 0–100% per ink
- Ilungele:
- ukuphrinta, ukupakisha, umsebenzi wokucindezela olungele iphrinta
Iyini RGB?
I-RGB ichaza umbala njengesiteshi sesithathu sokukhanya — red, green kanye ne-blue — ngakunye kusuka ku-0 kuya ku-255. Ikhombisa ukuthi izikrini zisebenza ngempela: zonke ezintathu ku-255 zenza umhlophe, zonke ku-0 zenza mnyama. I-RGB ifanele uma kudingeka ukubala ngombala, kanti i-rgba() yengeza ukuphelelwa ukucacisa.
- Isakhiwo:
- rgb(R, G, B)
- Ibanga:
- 0–255 per channel
- Ilungele:
- ikhodi, canvas, ukuphelelwa ukucacisa nge-rgba()
Ithebula lokubhekisela le-CMYK kuya ku-RGB
Imibala ye-CSS evame ukusetshenziswa, iguqulwe ukusuka ku-CMYK iye ku-RGB.
