Izikrini zihlanganisa ukukhanya, ukuphrinta kuhlanganisa i-inki — ngakho-ke ikhodi ye-HEX kumele iguqulwe ngaphambi kokuthi into iyophrintwa. Lo mciji ukunika amaphesenti e-cyan, magenta, yellow kanye no-key ahambisana nombala wakho wewebhu ngangokunokwenzeka nge-inki.
Indlela okuhunyushwa ngayo HEX kuya ku-CMYK
- Guqula ikhodi ye-HEX iye ku-RGB bese wahlukanisa wonke channel ngo-255.
- Bala ingxenye ye-key (black): K = 1 − max(R, G, B).
- Thola ezinye i-inks ngokususa le ngxenye ye-black: C = (1 − R − K) / (1 − K), futhi usebenzise ifomula efanayo ku-magenta nase-yellow.
- Phindaphinda wonke amanani amane ngo-100 ukuthola amaphesenti. I-black ehlanzekile iphenduka ngo-0/0/0/100.
Isibonelo esisebenzayo
Lokhu kuwukulinganisa okungekho kudivayisi okukodwa. Ukuphrinta kweqiniso kuncike ephepheni, inki kanye nephrofayili ye-ICC, ngakho thatha umphumela njengendawo yokuqala futhi uhlale uhlole iproof yemibala ebalulekile ku-brand.
HEX no-CMYK kuchazwe
Iyini HEX?
Ikhodi ye-HEX iyi-hexadecimal yezinombolo eziyisithupha egcina iziteshi ezibomvu, eziluhlaza kanye neziluhlaza okwesibhakabhaka zombala ngemuva kwe-#. Iphara ngalinye lamadijithi limela isiteshi esisodwa, kusuka ku-00 (akukho) kuya ku-FF (kugcwele), okunikeza imibala eyizigidi ezingama-16.7 njengase-RGB ngokufaka okubhaliwe okufushane. I-HEX iyinketho ezicini ze-CSS, amathuluzi okwakha nomhlahlandlela webhrendi.

- #RRGGBB
- Ibanga:
- 00–FF per channel
- Ilungele:
- CSS, ukudluliswa kokuklama, imihlahlandlela ye-brand
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
Ithebula lokubhekisela le-HEX kuya ku-CMYK
Imibala ye-CSS evame ukusetshenziswa, iguqulwe ukusuka ku-HEX iye ku-CMYK.
