Yintoni umahluko we-RGB kunye ne-CMYK kwimeko ye-Umshicileli we-Inkjet?
Imodeli yombala we-RGB yimibala emithathu ephambili yokukhanya. Ebomvu, eluhlaza, neBlue. Le mibala mithathu iphambili, enemilinganiselo eyahlukileyo enokudala uluhlu lwemibala. Kwithiyori, ukukhanya okuluhlaza, obomvu kunye nohlaza okwesibhakabhaka kunokudibaniswa namanye ama-shades.
Ikwaziwa njenge-KCMY, i-CMY imfutshane kutyheli, i-cyan kunye ne-magenta. Le yimibala eyenza i-intermediates kwi-RGB (imibala emithathu ephambili yokukhanya) idityaniswe kwizibini ezinombala ohambelanayo we-RGB.
Ngaphambi kokuba singene kwiinkcukacha, makhe siqwalasele ezi:
Kulo mfanekiso kucacile ukuba umbala we-CMY udibanisa ukuxuba. Lo ngowona mahluko uphambili, kutheni le nto umshicileli wethu weefoto kunye ne-UV umshicileli yi-KCMY? Oku kungenxa yokuba itekhnoloji esetyenziswayo ngoku ayikwazi ukuvelisa i-pigments ephezulu. Umxube we-tricolor unokwahluka kancinane kumnyama wesiqhelo, kodwa endaweni yoko bubomvu obumnyama, obufuna ukuba yi-inki ekhethekileyo emnyama enokuthi ingabikho.
Ngokwethiyori, i-RGB ngokwenene ngumbala wendalo, wona umbala ofumaneka kuzo zonke izinto zendalo esikwaziyo ukuzibona.
Kumaxesha anamhlanje, amaxabiso ombala we-RGB aboniswa kwizikrini ezihlelwa ngemibala eqaqambileyo. Oku kungenxa yokusulungeka kokukhanya ngowona mbala ubalaseleyo, kwaye ke umbala owona uchaneke kakhulu ubonisa amaxabiso emibala ye-RGB.
Ngokuchasene noko, imibala ye-KCMY 4 imele iipateni zemibala ejoliswe ngokukodwa kushicilelo lwemizi-mveliso. Azikhanyisi.Njengoko ipateni yombala ishicilelwe kwiintlobo ezahlukeneyo zeendaba zisebenzisa izixhobo zanamhlanje zoshicilelo Imo yombala ingahlelwa phantsi kwemo ye-KCMY.
Makhe sijonge umahluko wendlela yombala we-RGB, kunye ne-KCMY iindlela zombala kwi-Photoshop:
(uyilo lomzobo luqhele ukuthelekisa umahluko phakathi kwemibala emibini yenjongo yoshicilelo lokukrazula)
I-Photoshop imise iindlela ezimbini zemibala ye-RGB kunye ne-KCMY ukwenza umahluko. Enyanisweni, umahluko awukho mkhulu emva kokuba uprintwe, kodwa ukuba ujongana nomfanekiso kwi-RIP ngemodeli ye-RGB, uya kubona isiphumo soshicilelo singumahluko omkhulu xa uthelekisa nesithombe sokuqala.
