Ukwahlula imibala kwenza ukushicilelwa kwimibala embala kwimifanekiso ephepheni
Ukwahlula umbala yinkqubo apho iifayile zedijithali ezipheleleyo zedijithali zizahlukana zibe zixhobo zombala ngamnye zomshicileli wenkqubo emine. Yonke into efayili ifakwe kwintsebenziswano yemibala emine: i-cyan, i-magenta, i-yellow, kunye nomnyama, eyaziwa ngokuthi yi- CMYK kwihlabathi lokushicilela kwezorhwebo.
Ngokudibanisa le mibala emine yeengki, imibala eninzi yemifanekiso ingaveliswa kwiphepha eliprintiweyo. Kwinkqubo emine yokushicilela umbala, nganye yezohlulo ezine zombala isetyenziswe kwisitya sokushicilela esahlukileyo kwaye sibeke kwi-cylinder enye yokushicilela. Njengoko iiphetshana zephepha zihamba ngokushicilela umshini, nganye iplani idlulisela umfanekiso kumnye wembala emine kwiphepha. Imibala-esetyenziswa njengamaqhosha amancinci-ukudibanisa ukuvelisa umfanekiso obala.
I-CMYK Umbala weMpawu nguProjekti zePrinta
Umsebenzi owenziweyo wokwenza ukwahlula imibala ngokuqhelekileyo kulawulwa yinkampani yokushicilela ezoshishino, esebenzisa isofthiwe yokuthengisa ukwahlula iifayile zakho zedijithali kwimimiselo emine ye- CMYK kwaye udlulisele ulwazi oluhlukileyo kumbala kwiiplati okanye ngokuthe ngqo kwiimidiya zedijithali.
Uninzi lwabashicileli balisebenzisela umzekelo we-CMYK ukucacisa ngokuchanekileyo ukubukeka kwemibala kwimveliso yokugqibela eprintiweyo.
I-RGB iyona nto ibhetele ekubukeni kwe-Onscreen
I-CMYK ayilona mzekelo umbala ophezulu kumaphepha afanele ukujongwa kwikhredithi. Ziyakhelwe ngokugqithiseleyo usebenzisa umbala wombala weRGB (obomvu, obuluhlaza, obomvu). Imodeli ye- RGB iqulethe amathuba amaninzi kunomzekelo we-CMYK ngenxa yokuba iliso lomntu liyakubona imibala emininzi kunokuba inki ephepheni iphindwe kwakhona.
Ukuba usebenzisa i-RGB kwiifayile zakho zokuyila kwaye uthumele iifayile kumshicileli wezorhwebo, zihlala zihlukaniswe ngemibala emine imibala ye-CMYK yokuprinta. Nangona kunjalo, kwinkqubo yokuguqula imibala esuka kwi-RGB ukuya kwi-CMYK, kukho ukutshintsha kwemibala kwizinto ozibonayo kwisikrini kwizinto ezizaliswayo kwiphepha.
Ukuseta iiFayile zeDavidi zokuSahlukana koMbala
Abaqulunqi bezobugcisa kufuneka bamise iifayile zabo zedijithali ezenzelwe ukuhlukana kombala ezine kwimodi ye-CMYK ukukhusela iimpazamo ezingafaniyo zombala. Zonke i-software eziphezulu-i-Adobe Photoshop, i-Illustrator kunye ne-InDesign, iCorel Draw, i-QuarkXPress kunye neenkqubo ezininzi-zinikeza lo msebenzi. Kuphela nje umcimbi wokutshintsha okukhethwa kukho.
Ngaphandle: Ukuba iprojekthi yakho eprintiweyo iqukethe umbala wendawo, umbala oqhelekileyo kufuneka uhambelane nombala othize, loo mbala awufanele umakwe njengombala we-CMYK. Kufuneka ishiywe njengombala wendawo, xa ukuhlukaniswa kombala kwenziwe, kuya kuvela ngokwahlukileyo kwaye kuprintwe ngokwakhe umbala okhethekileyo.
