Refer to the data below when themaximum density is set to 3.1 D, or when gradation analysis software is used to takemeasurements on the monitor.* The LINEAR output cannot be set for some printer models.In this case, try to select an output setting as close as possible to LINEAR.Ideal density values in LINEAR LINEStep 1 2 3 4 5 6 7 8 9 10 113.2 D 0 0.32 0.64 0.96 1.28 1.60 1.92 2.24 2.56 2.88 3.203.1 D 0 0.31 0.62 0.93 1.24 1.55 1.86 2.17 2.48 2.79 3.1012 Bit 0 410 819 1229 1638 2048 2457 2867 3276 3686 40958 Bit 0 26 51 77 102 128 153 179 204 230 255Possible causes of non-linearity in measurement values:* Inadequate calibration of printer and high-definition monitor* Inadequate settings for CXDI printer parameters* Faults in printer or high-definition monitorMax settingdensityFilm basedensity
