Kodak 9500 manual Contrast without ATP

Page 77

Contrast (without ATP)

Contrast determines the ability of the scanner to detect subtle

 

differences in gray levels. It is defined as a percentage, from

 

0 to 100%. A high contrast value will produce a scanned output

 

of mostly blacks and whites (only large changes in gray levels are

 

detected). A low contrast value will produce a scanned output of

 

mostly midtones (more subtle change in gray levels are detected).

 

It is recommended that a relatively high contrast value be used to

 

optimize the quality of text.

 

Refer to Chapter 6, Scanner-unique Commands for a description

 

of the KX/Y/Z command.
