The options are described below:
Figure Advance dialog (density correction)
Gamma Pattern
This option corrects distortions from nonlinear image representation. Scanner sensors are
generally designed to generate output linear to the density of the light reflected from the
document. However, most output terminals do not produce output that has the desired linear
relation to the input, and the resulting distortion must be corrected.
One of the following can be selected as a correction pattern: "Normal", "Soft", "Sharp",
"Download Pattern", or "Custom".
