1 to 29
.
The displayed value on the left is the saved value, and the value on the right is the
modified value.
The analysis value obtained by the Automated ROI or the Fixed ROI will be converted to
a density corresponding to the setting.
The following table is the density when the printer’s LUT is linear, the maximum density
is 3.2 D, and the minimum density is 0.2 D.

Set the contrast.
Touch or to select a setting from 1 to 29 .
The displayed value on the left is the saved value, and the value on the right is the modified
value.
Higher values result in higher contrast, and lower values result in lower contrast.

Brightness
By adjusting the brightness, the density
of the whole area can be changed. For
example, a high brightness setting will
shift the LUT graph toward the left,
raising the density of the whole image,
as illustrated in the right.
Similarly, a low brightness setting will
shift the LUT graph to the right,
lowering the density of the whole
image.
Contrast
Adjusting the contrast setting as shown
below changes the contrast of the whole
image.
