Specify the contrast to print multi-level images (gray scale).
Format
contrast=value
Specified value and behavior
Enter an integer or decimal within the range of 0.01 to 999 to specify the "contrast". The difference in appearance between the lightest and the darkest spots in the printed image increases when a value greater than "1.0" is specified, and decreases when a value less than "1.0" is specified.
Explanation
If "0.01" is specified, images are completely neutral gray.
If "999" is specified, images are completely white.
This printing option is ignored when printing two-level images (black and white only).
If this printing option is specified, the setting in "N. Contrast" on the RTIFF Menu is ignored.
This printing option may be invalid on some color data.
