Watermark in Crystal Reports

[sarend]

I already know how to create a watermark in Crystal, however, I need to know how to make it permanent. Most of our reports are delivered to our internal customers as word, pdf, or excel files. These customers tend to share our reports to others. Because of this, we would like some sort of permanent watermark or footer that designates that our team created this report and cannot be removed or changed by our customers. Is there a way to do this? Any help is appreciated.
