Short video that shows how to apply a background or watermark to a PDF file using Win2PDF Pro.
A "Background" file will appear "behind" the printed results -- this would typically be something like a company letterhead or standard form document.
A "Watermark" file will appear "on top" of the printed results -- this would typically be something like text indicating "draft", "confidential", "do not copy", etc.
When you set either a Background or Watermark file, this file must have previously been created and saved as a PDF file.
** Note: The security features are only available in the Win2PDF Pro version of the product.
