* ES-1000 above is an optional device of EFI, which is originally manufactured by Gretag Macbeth (I1) but
customized exclusively for EFI. The ES-1000 is hardware key for optional EFI Color Profiler or Spot-On,
and these options will not be started unless the ES-1000 is connected to them.
Simple calibration (ColorCal)
ColorCal enables calibration for the GA-1211 by measuring the toner density using the built-in scanner of the
MFP, without preparing any expensive measurement devices such as spectrometers or densitometers.
ColorCal can be operated by starting Calibrator on a computer connected to the MFP, or from the control
panel of the MFP without a computer. Note that the accuracy of the calibration with ColorCal is lower than
that of calibration with a measurement device because the built-in scanner of the MFP is not originally
developed as a measurement device. If problems such as false contour, color spots in gray areas or color
imbalance occurred after calibration with ColorCal, such problems are often resolved by recalibrating with a
measurement device such as DTP-32 or ES-1000.
The differences between the ColorCal calibrations from the touch panel of the MFP and from Calibrator are
shown below.
