I-CMYK ibalulekile kumbala oqondile ekuphrintiwe
Imodeli yembala ye-CMYK isetshenziselwa inqubo yokunyathelisa. It isetshenziswa ehhovisi lakho inkjet kanye labashicileli laser kanye nemishini esetshenziselwa amaphrinta professional commercial. Njengomklami wemifanekiso, kubalulekile ukuthi uqonde kokubili amamodeli wombala we-CMYK no-RGB nokuthi uma uzodinga ukuyisebenzisa.
Indlela i-RGB eholela ngayo ku-CMYK
Ukuze uqonde imodeli yemibala ye-CMYK, kungcono ukuqala ngokuqonda umbala we-RGB.
Imodeli yombala we-RGB yenziwe ngokubomvu, eluhlaza nokuhlaza okwesibhakabhaka. Isetshenziselwa ukuqapha ikhompyutheni yakho futhi yilokho ozokubuka amaphrojekthi akho ngenkathi esesesikrinini. I-RGB igcinwa ngemiklamo eyenzelwe ukuhlala esibukweni (amawebhusayithi, ama-pdfs, nezinye ihluzo zewebhu, isibonelo).
Lezi zinhlobonhlobo zingabhekwa kuphela ngokukhanya kwemvelo noma okukhiqizwayo, njengokuqapha kwikhompyutha, hhayi ekhasini elinyathelisiwe. Yilapho i-CMYK ingena khona.
Uma imibala emibili ye-RGB ixutshwe ngokulinganayo iveza imibala yesimodeli se-CMYK, eyaziwa ngokuthi yizinkampani zokuxoshwa.
- Okuhlaza nokuhlaza okwesibhakabhaka kudala i-cyan (C).
- Okubomvu ne-blue kubumba i-magenta (M).
- Okubomvu neluhlaza kudala ophuzi (Y).
- Okumnyama kufakwe emodeli ngoba ayikwazi ukudalwa ngeziqephu ezi-3 zokubamba (uma zihlangene zidala umnyama omnyama). I-K, noma "ukhiye," imelela abamnyama.
CMYK kuNqubo yokuPrinta
Inqubo yokunyathelisa imibala emine isebenzisa amapulethi amane okunyathelisa ; enye ye-cyan, eyodwa ye-magenta, enye yephuzi, neyodwa emnyama. Lapho imibala ihlangene ephepheni (empeleni iphrintiwe njengamaqabunga amancane), iso lomuntu libona isithombe sokugcina.
CMYK ku-Graphic Design
Abaqambi bezithombe kufanele babhekane nendaba yokubona umsebenzi wabo esikrinini ku-RGB, nakuba isiqeshana sabo sokugcina esizophrinta sizoba se-CMYK. Amafayela adijithali kufanele aguqulwe ku-CMYK ngaphambi kokuwathumela kumaphrinta ngaphandle uma kuchazwe ngenye indlela.
Lolu daba lusho ukuthi kubalulekile ukusebenzisa "ukuthungwa" lapho uhlela ukuthi ukufaniswa kombala okubalulekile kubalulekile. Isibonelo, i-logo yenkampani kanye nezinto zokufaka uphawu lokufaka uphawu lokungena ngemvume zingasebenzisa umbala ocacile njengoJohane Deere oluhlaza. Umbala obonakalayo kakhulu futhi ukuguqulwa kwezinguquko kakhulu kuzo kuzobonakala, ngisho nomthengi ojwayelekile.
Ama-swatches anika umklami kanye neklayenti ngesibonelo esinyathelisiwe sokuthi umbala uzobukeka kanjani ephepheni. Umbala we-swatch okhethiwe ungaboniswa ku-Photoshop (noma uhlelo olufanayo) ukuqinisekisa imiphumela efunayo. Ngisho noma umbala on-screen ngeke uqhathanise ngokuqondile, uyazi ukuthi umbala wakho wokugcina uzobukeka kanjani.
Ungathola futhi "ubufakazi" (isibonelo sekhasi eliphrintiwe) kusuka kwiphrinta ngaphambi kokuba wonke umsebenzi usebenze. Lokhu kungase kubambezele ukukhiqizwa, kodwa kuzoqinisekisa ukuthi imbala efana nobani.
Kungani usebenza ku-RGB futhi uguqulele ku-CMYK?
Umbuzo uvame ukuvela ngokuthi kungani ungafuni ukusebenza ku-CMYK ngenkathi uhlela ucezu oluhloselwe ukuphrinta. Ngokuqinisekile ungakwazi, kodwa kuzodingeka uthembele kulabo abathungayo kunalokho okubonayo esikrinini ngoba isimiso sakho sisebenzisa i-RGB.
Enye inkinga ongayena kuyo ukuthi ezinye izinhlelo ezifana ne-Photoshop zizokwehlisa imisebenzi yemifanekiso ye-CMYK. Lokhu kungenxa yokuthi uhlelo lwaklanyelwe ukuthola izithombe ezisebenzisa i-RGB.
Izinhlelo zokuklama ezifana ne-InDesign ne-Illustrator (zombili izinhlelo ze-Adobe) ezizenzakalelayo ku-CMYK ngoba zenzelwe abakhiqizi. Ngenxa yalezi zizathu, abaklami bezithombe bavame ukusebenzisa i-Photoshop ezakhiweni zezithombe bese bathatha lezo zithombe zibe uhlelo lokudizayini oluzinikezele lwezakhiwo.
