Kukho imizekelo emininzi abayili bemifanekiso abasebenzisa ukulinganisa ngokuchanekileyo nokuchaza umbala. I-RGB iphakathi kweyona nto ibaluleke kakhulu kuba yiyo ikhompyutha yethu yokuhlola ilisebenzisa ukubonisa itekisi kunye nemifanekiso . Kubalulekile ukuba abayili bemifanekiso baqonde umahluko phakathi kwe-RGB kunye ne-CMYK kunye neendawo zokusebenza ezifana ne-sRGB kunye ne-Adobe RGB. Ezi ziza kumisela indlela umbukeli abona ngayo iiprojekthi zakho ezigqityiweyo.
RGB Color Model Basics
Umzekelo wemibala ye-RGB isekelwe kwimfundiso yokuba yonke imibala ebonakalayo ingadalwa ngokusebenzisa imibala eyongezelelweyo eyongeziweyo ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka. Le mibala iyaziwa ngokuthi 'izongezo eziphambili' kuba xa zidibaniswe kwixabiso elilinganayo zivelisa ezimhlophe. Xa ezimbini okanye ezintathu zazo zidibaniswe ngeemali ezahlukileyo, ezinye iimveliso ziveliswa.
Umzekelo, ukudibanisa obomvu nokuluhlaza kumanani alinganayo kwenza i-yellow, eluhlaza kunye neyibhakabhaka ivelise i-cyan, kwaye obomvu nolubuluhlaza budala i-magenta. Ezi fomyula ezithile zenza imibala ye-CMYK esetyenziswa ekushicileleni.
Njengoko utshintshisa inani elibomvu, eluhlaza kunye nolubhakabhaka unikezwa ngemibala emitsha. Idibaniselwano inikeza imibala engapheliyo yemibala.
Ukongezelela, xa enye yale mibala eyongeziweyo eyona nto ingekho, ufumana umnyama.
Umbala weRGB kwi-Graphic Design
Imodeli ye-RGB ibalulekile ekuyiyileni imifanekiso ngoba isetyenziswe kubahloli bekhompyutha . Iskrini ufunda le ngqangi ngoku usebenzisa imibala engongeziweyo ukubonisa imifanekiso kunye nokubhala. Yingakho iliso lakho likuvumela ukuba ulungelelanise kuphela imibala ebomvu, eluhlaza, neyibhakabhaka kunye nemilinganiselo yombala wendlela yokujonga umbala weempawu zemibala emithathu ngokunjalo.
Ngoko ke, xa uklaza iiwebhusayithi kunye nezinye iiprojekti ezisekrini njengemiboniso, imodeli yeRGB isetyenziselwa ukuba imveliso yokugqibela ibonwe kwikhompyutheni yekhompyutha.
Ukuba, nangona kunjalo, uyilungiselela ukuprinta, uya kusebenzisa imodeli yemibala ye-CMYK. Xa uklanywa kwiprojekthi eya kujongwa kokubini kwesikrini kunye nokuprinta, kuya kufuneka uguqule ikopi yokushicilela kwi-CMYK.
Iphulo: Ngenxa yazo zonke iintlobo ezahlukeneyo zeefayile eziza kuveliswa ngabaqulunqi, kubalulekile ukuba ulungelelaniswe kwaye uchane ngokufanelekileyo igama lakho kwifayili ngenjongo efunwayo. Qulunqa iifayile zeeprojekthi kwiifolda ezahlukileyo zokuphrinta kunye nokusetyenziswa kwewebhu kwaye wongeze izalathisi ezinjenge-'CMYK 'ekupheleni kwamagama afayiliweyo afayiliweyo. Oku kuya kwenza lula umsebenzi wakho xa ufuna ukufumana ifayile ethile kumxhasi wakho.
Iintlobo zeeNdawo zokusebenza zoMbala weRGB
Kwimodeli ye-RGB yimibala eyahlukileyo yembala eyaziwa ngokuthi 'izithuba zokusebenza.' Ezi zibini eziqhelekileyo ezisetyenziswayo yiSRGB kunye ne-Adobe RGB. Xa usebenza kwiprogram yeprogram yeprogram efana ne-Adobe Photoshop okanye i-Illustrator, unokukhetha ukuba yeyiphi indlela yokusebenza.
- I-sRGB: Isixhobo sRGB sisetyenziswe kakuhle xa uklanywa kwiwebhu, njengoko yikho enye i-computer ehlola ngayo.
- I-Adobe RGB: Indawo ye-Adobe RGB iqukethe ukhetho oluninzi lwemibala engabonakali kwisithuba se-sRGB, ngoko kulungele ukusebenzisa xa uyilo lokuprinta. Kukwacetyiswa ukuba kusetyenziswe nezithombe ezithathwe ngeekhamera zedijithali zobuchwepheshe (ngokuchasene nomgangatho wabathengi) kuba iikhamera eziphezulu zihlala zisebenzisa i-Adobe RGB space.
Unokungena kwingxaki nge-Adobe RGB imifanekiso xa ivela kwiwebhusayithi. Umfanekiso uza kubonakala umangalisa kwisofthiwe yakho kodwa ingabonakala ibonakale kwaye ingabi nemilayezo enamandla kwiphepha lewebhu. Ngokuqhelekileyo, kuchaphazela imibala efudumele njengama-oranges kwaye ihlawula kakhulu. Ukulungisa le ngxaki, vele uguqulwe umfanekiso kwiSRGB kwi-Photoshop kwaye ugcine ikhophi ekhethiweyo ukusetyenziswa kwewebhu.
