Kunamamodeli amaningi ama- graphic designer asebentisa ukukala ngokunembile nokuchaza umbala. I-RGB ingenye yezinto ezibaluleke kakhulu ngoba yilokho ikhompyutha yethu ihlola ukubonisa umbhalo nemifanekiso . Kubalulekile ukuthi abadwebi bezithombe baqonde umehluko phakathi kuka-RGB no-CMYK kanye nezikhala zokusebenza ezifana ne-sRGB ne-Adobe RGB. Lezi zizocacisa ukuthi umbukeli ubona kanjani amaphrojekthi akho aqediwe.
I-RGB Color Model Basic
Imodeli yombala we-RGB isekelwe kwinkolelo yokuthi yonke imibala ebonakalayo ingadalwa besebenzisa imibala eyinhloko yokwengeza ebomvu, eluhlaza, nohlaza okwesibhakabhaka. Le mibala yaziwa ngokuthi 'izithasiselo eziyinhloko' ngoba lapho zihlangene ngezilinganiso ezilinganayo zikhiqiza ezimhlophe. Uma ezimbili noma ezintathu zazo zihlanganiswa ngezilinganiso ezahlukene, ezinye imibala zikhiqizwa.
Isibonelo, ukuhlanganisa obomvu nokuhlaza okwenziwe ngokulingana kwenza i-yellow, eluhlaza neluhlaza okwesibhakabhaka kudala i-cyan, futhi obomvu nokuhlaza okwesibhakabhaka kudala i-magenta. Lezi fomula ezithile zakha imibala ye-CMYK esetshenziselwa ukunyathelisa.
Njengoba ushintsha inani elibomvu, eliluhlaza neluhlaza okwesibhakabhaka unikezwa ngemibala emisha. Inhlanganisela inikeza imibala engapheli yemibala.
Ukwengeza, uma omunye wale mibala eyengeziwe eyinhloko engekho, uthola omnyama.
Umbala we-RGB ku-Graphic Design
Imodeli ye-RGB ibalulekile ekudaleni imidwebo ngoba isetshenziselwa abahloli bekhompiyutha . Isikrini ufunda lesi sihloko ngokusebenzisa imibala enezengezo ukubonisa izithombe nombhalo. Yingakho ukuqapha kwakho kukuvumela ukuba ulungise kuphela imibala ebomvu, eluhlaza, nohlaza okwesibhakabhaka kanye nezinyathelo zombala womqapha wakho wokuqapha umbala wale mibala emithathu.
Ngakho-ke, uma udala amawebhusayithi kanye namanye amaphrojekthi askrini njengamaphrezentheshini, imodeli ye-RGB isetshenziswa ngoba umkhiqizo wokugcina ubhekwa kukhombisa ikhompyutha.
Uma kunjalo, uhlela ukuphrinta, uzosebenzisa imodeli yombala we-CMYK. Uma udala iphrojekthi ezobukwa kokubili esikrinini futhi iphrintiwe, kuzodingeka uguqule ikhophi yokuphrinta ku-CMYK.
Ithiphu: Ngenxa yalezi zinhlobo ezahlukene zamafayela abakhiqizi okufanele bakhiqize, kubalulekile ukuthi uhlelekile futhi ubeke igama lakho ngokuqondile ngamafayela akho ngenjongo oyifunayo. Hlela amafayela wephrojekthi kumafolda ahlukene ukuze uprinte futhi usetshenziswe kuwebhu bese ufaka izinkomba ezinjengokuthi '-CMYK' ekugcineni kwamagama wefayela afanele ukuphrinta. Lokhu kuzokwenza umsebenzi wakho ube lula uma udinga ukuthola ifayela elithile leklayenti lakho.
Izinhlobo ze-RGB Color Working Spaces
Ngaphakathi kwesibonelo se-RGB kunezikhala zombala ezahlukene ezibizwa ngokuthi 'izikhala zokusebenza.' Lezi ezimbili ezivame ukusetshenziswa kakhulu yi-sRGB ne-Adobe RGB. Uma usebenza ohlelweni lwe-software ehluzisayo njenge-Adobe Photoshop noma i-Illustrator, ungakhetha ukuthi iziphi izilungiselelo ozisebenzisayo.
- i-sRGB: Isikhala sRGB sisetshenziswe kangcono uma udala iwebhu, njengoba yilokho okuyikho okuqapha kukhompyutha.
- I-Adobe RGB: Isikhala se-Adobe RGB siqukethe ukukhethwa okukhulu kwemibala engatholakali esikhala sRGB, ngakho-ke kungcono ukusebenzisa uma uklanyelwe ukuphrinta. Kunconywa futhi ukusetshenziswa ngezithombe ezithathwe ngamakhamera wezedijithali zobuchwepheshe (ngokuphambene nomthengi-ezingeni) ngoba amakhamera aphezulu asebenzisa isikhala se-Adobe RGB.
Ungangena enkingeni ngezithombe ze-Adobe RGB uma zivela kuwebhusayithi. Isithombe sizobukeka simangalisa kwisofthiwe yakho kodwa singase sibukeke singenangqondo futhi singabi nemilayezo enamandla ekhasini lewebhu. Ngokuvamile, kuthinta imibala efudumele njengama-oranges futhi ibuyelela kakhulu. Ukulungisa le nkinga, vele uguqule isithombe ku-sRGB ku-Photoshop bese ulondoloza ikhophi ekhethiwe ukusetshenziswa kwewebhu.
