Yintoni umahluko phakathi kwe-RGB kunye ne-CMYK kwimeko ye-Iphrinta ye-Inkjet?
Imodeli yombala we-RGB yimibala emithathu ephambili yokukhanya. Ubomvu, Uluhlaza, kunye noBhlowu. Le mibala emithathu ephambili, enemilinganiselo eyahlukeneyo enokudala uluhlu lwemibala. Ngokwethiyori, ukukhanya okuluhlaza, okubomvu kunye nobhlowu kunokudityaniswa nezinye izithunzi.
Ikwaziwa nangokuthi yi-KCMY, i-CMY sisishunqulelo segama elithi mthubi, i-cyan kunye ne-magenta. Le yimibala eyenza ii-intermediates kwi-RGB (ii-shades ezintathu eziphambili zokukhanya) ezidityaniswe ngababini ezimbala ohambelanayo we-RGB.
Ngaphambi kokuba singene kwiinkcukacha, makhe siqwalasele ezi:
Kumfanekiso kuyacaca ukuba umbala we-CMY kukuxuba okungaphantsi. Lo ngumahluko ophambili, kutheni ke ngoko iprinta yethu yeefoto kunye neprinta ye-UV yi-KCMY? Oku kungenxa yokuba iteknoloji esetyenziswayo ngoku ayinakuvelisa imibala ecocekileyo kakhulu. Umxube we-tricolour unokwahluka kancinci kumnyama oqhelekileyo, kodwa endaweni yoko ubomvu obumnyama, nto leyo efuna ukuba kubekho i-inki emnyama ekhethekileyo enokuthomalalisa.
Ngokwethiyori, i-RGB ngumbala wendalo, umbala ofumaneka kuzo zonke izinto zendalo esikwaziyo ukuzibona.
Kule mihla, amaxabiso ombala we-RGB aboniswa kwizikrini ezihlulwe ngemibala eqaqambileyo. Oku kungenxa yokuba ukukhanya kucocekile, kwaye ke ngoko umbala ochanekileyo ubonakalisa amaxabiso ombala we-RGB. Ngoko ke singahlulahlula imibala ebonakalayo njengemibala ye-RGB.
Ngokuchasene noko, imibala ye-KCMY 4 imele iipateni zemibala ezenzelwe ngokukodwa ukuprinta kwemizi-mveliso. Azikhanyi. Ukuba nje ipateni yemibala iprintiwe kwiindidi ezahlukeneyo zemidiya kusetyenziswa izixhobo zanamhlanje zokuprinta, imo yemibala inokuhlelwa phantsi kwemo ye-KCMY.
Makhe sijonge umahluko we-RGB color mode, kunye ne-KCMY color modes kwi-Photoshop:
(ngesiqhelo uyilo lwemizobo ludla ngokuthelekisa umahluko phakathi kwemibala emibini yenjongo yokuprinta ngokukrazula)
I-Photoshop ifake imibala emibini i-RGB kunye ne-KCMY ukuze yenze umahluko. Enyanisweni, umahluko awumkhulu emva kokuprintwa, kodwa ukuba udibanisa umfanekiso kwi-RIP kunye nemodeli ye-RGB, uya kubona ukuba isiphumo sokuprinta sikhulu xa sithelekiswa nefoto yokuqala.
