Gradation is decreased. Gradation is increased.
Explanation
When an original is scanned in the Black mode or the Gray scale mode, changing the scan density according to
density area (low-, medium- or high-density area) allows a user to adjust the reproducibility of halftones
(gradation). Adjust the gamma curve balance, in order to change the gradation, depending on the type of original
or at a user’s request.
* This adjustment will have an effect only on the image scanned in the Black mode or the Gray scale mode.
