Ibinzana elithi "ngaphandle kwebhola" libhekisela kwimimandla yemibala engenakuphinda iphinde ikhutshwe ngaphakathi kwendawo yombala we- CMYK esetyenziselwa ukushicilelwa kwezorhwebo. Isofthiwe yezobuGcisa yenzelwe ukusebenza nemifanekiso kwi-RGB umbala wendawo ngexesha lokulungisa inkqubo.
Umbala webala we-RGB unomqolo omkhulu wemibala ebonakalayo ngaphezu kwe- CMYK echaza ukuba kutheni imibala ye-RGB idla ngokumnyama xa ithunyelwa kwi-CMYK. Xa ushicilela umfanekiso kufuneka uveliswe kwakhona ngee inks kwaye ezi inki azikwazi ukuvelisa uluhlu olufanayo lwembala esiyayibona ngamehlo ethu ngenxa yokuba indawo yombala weRGB isebenzisa ukukhanya, kungekhona i-pigment, ukuvelisa umbala.
Ngenxa yokuba umbala wombala onokuphinda uzaliswe ngeyinki encinci kuneyona nto esiyibonayo, nayiphi na imibala engakwazi ukuphinda iphinde ikhutshwe ngeyinki ibhekiswe "ngaphandle kwebala." Kwi-software yefriji, uhlala ukhangeleka ngaphandle kwesilumkiso se-gamut xa ukhetha imibala eya kutshintsha xa umfanekiso uguqulwa kwi-RGB umbala wombala osetshenziswe kwinkqubo yokuhlela, kwisixhobo se-CMYK esisetyenziselwa ukushicilelwa kwezorhwebo.
Umfanekiso ongezantsi usinikeza umbono ocacileyo wokuqonda i-gamut. Ibhokisi elingaphandle lonke umbala owaziwayo kumntu wanamhlanje, kuquka yonke imibala esiyibonayo kunye nabo singenako, njenge-Ultraviolet kunye ne-Infrared.
Isangqa sokuqala imibala yezigidi ezili-16 ezifumaneka kwi-palette yombala we-RGB kunye nesangqa sangaphakathi yonke imibala enokuphinda ikhutshwe ngumshicileli wokushicilela. Le ndawo ichaphazelekayo, kuzo zonke iinjongo kunye neenjongo, ngumgodi omnyama. Ukuba uhamba ukusuka kwikona yebhokisi ukuya kwicatshulwa, imibala ibonakala ibumnyama. Baqala ukukhanya xa uhamba.
Ukuba ukhetha umbala kwi-RGB gamut, kuya kuba nelinganayo kwi-CMYK gamut kodwa, ngokwahlukileyo. Ukuba umbala uhambela phambili kwinto ecacileyo.
