Calibration
(XEScan Reflection only)
Your system is now about to be calibrated. This ensures both color matching and length correction. Therefore a
calibration is recommended for color and black and white systems alike. It is recommended to perform all
calibrations as some printer settings will otherwise not allow copying.
Target Dialog
After a right-click on the quality settings the following dialog is shown:
Edit media parameters
Under certain circumstances it may be necessary to change the default media parameters Ink-limit or Gamma.
But this is usually not necessary, and an incorrect value can lead to a color mismatch of original and copy. Please
print the file grayscale.TIFF from the XEScan installation folder with the settings GAMMA=1.0 and Ink-limit=100%.
Please adjust the ink limit so that the dark gray areas are still distinguishable. The darkest area must be totally
black.
Keep this setting. Then change the GAMMA value, until the brightness of 50% GREY is exactly in the middle of
the range between 100% WHITE and 100% BLACK.
