Calibration could be implemented in several stages during the color rendering
processes. One possible and efficient place to put the calibration to work is in
the screen table itself. In order to make the screen intelligent enough to adjust
the factor results from output device characteristics, such as the dot gain, toner
characteristics, etc., the method is introduced to create a gamma function with
normalized gradation curve. Some color balance adjustment features (contrast, brightness,
saturation and color strength) also have been taken into consideration.
