Confidential watermark examples
Confidential PDF watermark examples: wording, color, tiling, and mistakes that make the mark useless. Then add CONFIDENTIAL in your browser, no upload.

Why watermark a document?
Why watermark PDF documents: drafts and confidential files get a visible status label. Not encryption. When a mark helps a reader, and when it does not.
