Secure Watermark
When the Secure Watermark mode is enabled (with the standard Secure
Watermark kit), the machine embeds invisible text in the background of
printed or copied documents. The embedded text becomes visible when
the documents are copied, alerting users to unauthorized duplication or
information leakage. The embedded text can be customized in the
machine settings.
