The more even the contrast between the hidden text and the background is, the harder it will be
to see the hidden text on the original, but the less the hidden text will appear when it is copied.
It is recommended you make a copy of the original after adjusting the contrast to confirm that
the secure watermark becomes visible as desired.
NOTE
The Character/Background Contrast Adjustment settings are retained until the next time they are
changed.
