Subject Re: Is there a difference between Watermark & Stamp ?

Adam ,

I'm concerned about showing the watermark in the PDF, but what you are 
saying about printing it only is a nice option too.

I have a PDF with watermarks ... I will try what you have mentioned, and I 
will see what I will get.
Thanks a lot for the tips.

Best regards ,
Hesham
