Ngokumalunga nomahluko phakathi kwe-rgb kunye ne-cmyk, sicinge ngeyona ndlela ingcono ukuze wonke umntu ayiqonde.Apha ngezantsi kuzotywe ilivo lengcaciso.
Umbala oboniswe ngumboniso weskrini wedijithali ngumbala oqondwa ngeliso lomntu emva kokuba ukukhanya okukhutshwa ngumthombo wokukhanya kufakwe ngqo kwiliso lomntu.Ubukhulu bemibala emithathu ephambili ye-RGB ivelisa ukukhanya okuqaqambileyo, okuyindlela eyongeziweyo yombala, kwaye okukhona kugxininiswa ngakumbi, kuqaqambe ngakumbi.
I-RGB yindlela "+",
I-RGB yimibala yephotosynthetic, kwaye imibala ixutywe ngokusekwe ekukhanyeni.Umnyama yimeko engenanto yemibala eyahlukeneyo, elingana nephepha elimhlophe elingenawo nawuphi na umbala.Ngeli xesha, ukuba ufuna ukuvelisa umbala, kuyimfuneko ukwandisa ukukhanya kwemibala eyahlukeneyo ukuyivelisa.Xa zonke iintlobo zemibala zongezwa kwixabiso eliphezulu, umhlophe wenziwa.
Ukukhanya kwe-RGB ngqo emehlweni
Umbala wento eprintiweyo yimbonakaliso yokukhanya okujikelezayo kwiphepha elingaphezulu kwiliso lomntu.I-CMYK yindlela yombala othabathayo, okukhona uqokelela, kokukhona usiba mnyama.Ushicilelo lwamkela imo yemibala emine yemibala emithathu ephambili kunye nomnyama ukuqonda ukuprintwa kwemibala epheleleyo.
CMYK yi "-" indlela,
Ukushicilela, inkqubo ichasene nje.Iphepha elimhlophe linqanaba lemibala, kwaye umthwali wemibala akasekho ukukhanya, kodwa iintlobo ezahlukeneyo zeinki.Ekuqaleni kokushicilela, iphepha elimhlophe ngokwalo lifikelele kwixabiso eliphezulu lombala.Ngeli xesha, ukuba umbala uza kuboniswa, kuyimfuneko ukugubungela umhlophe ngeyinki.Xa i-inki iba ngqindilili kwaye ijiyile, umhlophe ugqunywa ngakumbi nangakumbi.Xa imibala emithathu ye-CMY igubungela umphezulu wephepha, umbala obonisiweyo umnyama, oko kukuthi, imeko yokulahlekelwa ngokupheleleyo yiyo yonke imibala.
Ukukhanya kwe-CMYK kubonakaliswe kwiso
I-RGB color gamut ibanzi, kwaye i-CMYK color gamut ilinganiselwe xa kuthelekiswa nombala we-RGB, ngoko ke kukho iimeko apho imibala kwi-RGB ayinakuboniswa ngexesha lokushicilela.Imibala engabandakanywanga kwi-CMYK yombala we-gamut iya kulahleka ngexesha lokushicilela, ngoko kukho "umahluko wombala".
Xa isimboli yesilumkiso ivela, ebonisa ukuba lo mbala awunakuprintwa ukubonisa
Ukuba injongo yoqobo kukushicilela, ngoko ke imo ye-CMYK ingasetyenziswa ngokuthe ngqo xa usenza.Kodwa ngamanye amaxesha, ukuba imisebenzi ethile kufuneka iqhutywe kwimo ye-RGB, okanye ukuba umsebenzi ugqityiwe kwimowudi ye-RGB, xa ushicilelo lokugqibela luza kwenziwa, ekugqibeleni kuyimfuneko ukuguqula imo ye-RGB kwimo ye-CMYK, kwaye imisebenzi engazanelisiyo iimfuneko zongqamaniso lwemibala Imibala iyahlengahlengiswa phambi koshicilelo.
Umzekelo, imibala kwi-RGB iya kuqaqamba kakhulu, kwaye xa iguqulelwe kwi-CMYK, imibala iya kuba buthuntu.
OKULULU LUFANAYO (RGB)
OKULUHLAZA OKUFANAYO (CMYK)
Isizukulwana salo mahluko wemibala kufuneka sinxibelelane ngokukhutheleyo kwaye sichaze nomthengi xa umthengi esithumelela uxwebhu, ukuze kugwenywe ukungaqondani okungeyomfuneko.
