With 10 bit processing the error rate is high in low tonal areas during calculation With 16 bit processing accuracy is significantly improved resulting in fewer conversion errors Emulation Function To take full advantage of the 12 bit LUT and 16 bit internal pro cessing capabilities EIZO has equipped the ColorEdge CG221 with an emulation function Simply by obtaining the ICC profile of another monitor and using EIZO s ColorNavigator software the ColorEdge CG221 can emulate its color characteristics This is useful when an other monitor is the standard monitor in a workflow when different models are used in a multi monitor setup or for a remote proofing environment where the client designer and printer want to be sure that their various monitors are displaying color the same way Monitor for Emulation k Lege raar Pa boa r bt a sh baa 1 eee Fiti Pasa fer wa a Emulate colors 73 target E x monitor s ICC profile EC of target monitor Select ICC profile of target monitor in ColorNavigator Factory Adjustment Of Gamma Each ColorEdge CG221 monitor is adjusted at the factory to a gamma level of 2 2 This is accomplished by measuring the R G and B gamma values from 0 to 255 then using the monitor s LUT with its 4 096 tone palette to select the 256 most appropriate tones to achieve the 2 2 value The benefit of factory adjustment2.
