Yintoni umahluko phakathi kwe-RGB kunye ne-CMYK ye-Inkjet yomshicileli?
Imodeli yombala we-RGB ibhekiselele kwimibala emithathu esisiseko yokukhanya: Obomvu, oluhlaza, noBlue, ukukhanya kombala okuthathu okunobungakanani obahlukileyo besamba, kunokuvelisa iintlobo ezahlukeneyo zokukhanya kombala, ngokwethiyori, obomvu, oluhlaza, noluhlaza okwesibhakabhaka. ixutywe kuyo yonke imibala.
Kwi-KCMY, i-CMY imfutshane yetyheli, cyan, kunye ne-magenta. Le yimibala ephakathi yeRGB (imibala emithathu esisiseko yokukhanya) exutywe ngababini, ngumbala ohambelanayo weRGB.
Ngaphambi kokuba singene kwiinkcukacha, makhe sijonge oku kulandelayo:
Kulo mfanekiso, sinokubona ngokucacileyo ukuba umbala we-pigment ye-CMY yi-subtractive mixing, eyona nto ibalulekileyo, ngoko kutheni umatshini wethu weefoto kunye nomshicileli we-UV ngu-KCMY? i-pigments, umxube we-tricolor uhlala ungengomnyama uqhelekileyo, kodwa ubomvu obumnyama, ngoko ke i-inki ekhethekileyo emnyama u-K ukuze unciphise.
Ukuthetha ngokwethiyori, i-RGB ngokwenene ngumbala wendalo, ongumbala wazo zonke izinto zendalo esizibona ngamehlo ethu.
Kumashishini anamhlanje, amaxabiso ombala we-RGB asetyenziswa kwiscreen kwaye ahlelwa njengemibala ekhanyayo. Oku kungenxa yokuba umbala ococekileyo wokukhanya ngowona uphezulu, ngoko ke umbala obonisa kakuhle amaxabiso ombala we-RGB.Ngoko ke singakwazi ukuhlela yonke imibala ebonakalayo njengexabiso lemibala ye-RGB.
Ngokwahlukileyo, i-KCMY imibala emine yipatheni yombala ezinikele ekushicileleni kwimizi-mveliso kwaye ayikhanyisi.Njengoko umbala ushicilelwe kumajelo ahlukeneyo ngezixhobo zoshicilelo zanamhlanje, imo yombala ingahlelwa njengemowudi ye-KCMY.
Ngoku makhe sijonge uthelekiso phakathi kwemowudi yombala weRGB kunye nemowudi yemibala ye-KCMY kwi-photoshop:
(ngesiqhelo, uyilo lomzobo luyakuthelekisa umahluko phakathi kwemibala emibini 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.
