I-CMYK ibalulekile kwiMpawu eziPhezulu ekuprintweni
Imodeli yombala we-CMYK isetyenziswe kwinkqubo yokuprinta. Isetyenziswe kwiofisi yakho yeenkjet kunye nabashicileli be-laser kunye noomatshini asetyenziswa ngabashicileli bezorhwebo. Njengomyili wemifanekiso, kubalulekile ukuba uqonde zombini imizekelo yeMCYYK kunye ne-RGB kwaye xa uzakufuna ukuyisebenzisa.
Indlela i-RGB ekhokelela ngayo kwi-CMYK
Ukuqonda imodeli yemibala ye-CMYK, kukulungele ukuqala ngokuqonda umbala we-RGB.
Umzekelo wombala weRGB wenziwe obomvu, obuluhlaza kunye nobuluhlaza. It isetyenziswe kwikhompyutheni yakho yekhompyutheni kwaye yiyo uza kujonga iiprojekthi zakho ngenkathi zisesikrinini. I-RGB igcinwa kwiiprojekthi ezenzelwe ukuhlala kwisikrini (iiwebhusayithi, i-pdfs, kunye nezinye iifayile zewebhu, umzekelo).
Noko ke, le mibala iyakubonwa kuphela ngendalo okanye ivelise ukukhanya, njengokwakheka kwikhompyutheni, kungekhona kwiphepha eliprintiweyo. Yilapho i-CMYK ingena khona.
Xa imibala emibili ye-RGB ixutywe ngokulinganayo ivelisa imibala ye-CMYK model, eyaziwayo njengeziqalo zokubambisa.
- Oluhlaza kunye noluluhlaza ludala i-cyan (C).
- I-Red kunye ne-blue idala magenta (M).
- Olubomvu kunye nohlaza kudala okwesibhakabhaka (Y).
- Umnyama udibaniswa kumzekelo kuba awukwazi ukudala kunye nezi-3 zokubambisa (xa zihlanganisiwe zidala umnyama omnyama). I-K, okanye "ikhiye," imele abamnyama.
CMYK kwinkqubo yokuprinta
Inkqubo yokuprinta imibala emine isebenzisa amacwecwe amane okushicilela ; enye ye-cyan, enye ye-magenta, enye yephuzi, enye ibe ngumnyama. Xa imibala ihlanganiswe ephepheni (empeleni iphrintiwe njengamaqhosha amancinci), iliso lomntu libona umfanekiso wokugqibela.
CMYK kwi-Graphic Design
Abaqulunqi bezobugcisa kufuneka bajongane nombandela wokubona umsebenzi wabo kwisikrini kwi-RGB, nangona iqela lokugqibela eliprintiweyo liya kuba kwi-CMYK. Iifayili zeDijama kufuneka ziguqulwe kwi-CMYK ngaphambi kokuzithumela kubashicileli ngaphandle kokuba kuchazwe ngenye indlela.
Lo mbandela uthetha ukuba kubalulekile ukusebenzisa "i-swatches" xa ukhetha ukuba impawu ezihambelana nombala zibalulekile. Ngokomzekelo, i-logo yeenkampani kunye nezinto zokubhenca zingasebenzisa umbala othile othi 'uJohn Deere ohlaza.' Umbala obonakalayo kwaye ubuninzi bezitshintshi kuzo ziya kuqondwa, nokuba kumthengi ophakathi.
I-Swatches inikeza umyili kunye nomthengi ngomzekelo oshicilelweyo wendlela umbala oya kubonakala ngayo kumaphepha. Umbala okhethiweyo we- swatch unokukhethwa kwi-Photoshop (okanye inkqubo efanayo) ukuqinisekisa iziphumo ezifunwayo. Nangona umbala onkrini ungakhange uqhathanise ne-swatch, uyazi ukuba umbala wakho wokugqibela uza kubonakala njani.
Unokufumana "ubungqina" (umzekelo wecandelo eliprintiweyo) ukusuka kumshicileli phambi kokuba umsebenzi uphumelele. Oku kunokulibazisa ukuveliswa, kodwa kuya kuqinisekisa ukufana kwembala.
Kutheni usebenza kwi-RGB kwaye uguqulele kwi-CMYK?
Umbuzo uvame ukuza malunga nokuba kutheni ungeke usebenze kwi-CMYK ngelixa udibanisa iqela elenzelwe ukuprinta. Ngokuqinisekileyo unako, kodwa kuya kufuneka uxhomekeke kulabo baqhankqalazo kunokuba ubone kwesikrini ngoba i-monitor yakho isebenzisa i-RGB.
Enye ingxaki onokuthi ungene kuyo kukuba ezinye iiprogram ezifana ne-Photoshop ziya kunciphisa imisebenzi yemifanekiso ye-CMYK. Oku kungenxa yokuba le nkqubo yenzelwe ukufotowa esebenzisa i-RGB.
Iiprogram zoyilo njenge-InDesign kunye ne-Illustrator (zombini iiprogram ze-Adobe ngokunjalo) ezingagqibekanga kwi-CMYK kuba zenzelwe abaklami. Ngenxa yezi zizathu, abaqulunqi beefayile bavame ukusebenzisa i-Photoshop kwimifanekiso yezithombe baze bathathe loo mifanekiso ibe yinkqubo yoyilo yokuzinikela.
