Uyini umehluko we-RGB kanye ne-CMYK endabeni ye-Iphrinta ye-inkjet?
Imodeli yombala we-RGB imibala emithathu eyinhloko yokukhanya. Okubomvu, Okuluhlaza, Nokuluhlaza okwesibhakabhaka. Le mibala emithathu eyinhloko, enezilinganiso ezihlukene ezingakha ububanzi bemibala. Ngombono, ukukhanya okuluhlaza, okubomvu nokuluhlaza okwesibhakabhaka kungahlanganiswa namanye ama-shades.
Yaziwa nangokuthi i-KCMY, i-CMY ifushane ngombala ophuzi, o-cyan kanye ne-magenta. Lena imibala eyakha okuphakathi ku-RGB (amathunzi amathathu okukhanya ayisisekelo) ahlanganiswe ngababili okuwumbala ohambisanayo we-RGB.
Ngaphambi kokuthi singene emininingwaneni, ake sicabangele lokhu:
Esithombeni kuyacaca ukuthi umbala we-CMY uwukuxuba okukhiphayo. Lona umehluko omkhulu, kungani-ke iphrinta yethu yesithombe nephrinta ye-UV iyi-KCMY? Lokhu kungenxa yokuthi ubuchwepheshe obusetshenziswayo okwamanje abukwazi ukukhiqiza ama-pigments ahlanzekile kakhulu. Ingxube ye-tricolor ingahluka kancane kunomnyama ojwayelekile, kodwa esikhundleni salokho ibomvu ngokumnyama, okudinga ukuthi uyinki okhethekile omnyama ongancishana.
Ngokwethiyori, i-RGB empeleni ingumbala wemvelo, okuwumbala otholakala kuzo zonke izinto zemvelo esikwazi ukuzibona.
Ezikhathini zanamuhla, amanani ombala we-RGB aboniswa ezikrinini ezihlukaniswa ngemibala egqamile. Lokhu kungenxa yokuhlanzeka kokukhanya kungcono kakhulu, ngakho-ke umbala onembe kakhulu ubonisa amanani emibala ye-RGB.Ngakho singase futhi sihlukanise imibala ebonakalayo njengemibala ye-RGB.
Ngokuphambene nalokho, imibala ye-KCMY 4 imelela amaphethini ombala ahloselwe ukuphrinta ngokwezimboni. Azinakukhanya.Inqobo nje uma iphethini yombala iphrintwa emithonjeni yezindaba ehlukahlukene kusetshenziswa izinto zesimanje zokuphrinta Imodi yombala ingahlukaniswa ngaphansi kwemodi ye-KCMY.
Ake sibheke umehluko wemodi yombala we-RGB , kanye ne-KCMY izindlela zombala ku-Photoshop:
(ngokuvamile idizayini eyingcaca izoqhathanisa umehluko phakathi kwemibala emibili yenhloso yokuphrinta kwe-rip)
I-Photoshop imise izindlela ezinemibala emibili i-RGB ne-KCMY ukuze yenze umehluko.Eqinisweni, umehluko awumkhulu ngemva kokuphrintwa, kodwa uma isithombe se-deal ku-RIP enemodeli ye-RGB, uzobona umphumela wokuphrinta umehluko omkhulu uma uqhathanisa nesithombe sokuqala.
Uma ufuna ukufunda okwengeziwe, sicelaXhumana nathi.
