CONFIDENTIAL

An approximation of how the stamp will sit on an A4 page. Exact placement depends on each page's own size.

A stamped watermark is page content, not a security control. Anyone with the right tools can remove it — use it to label documents, not to protect them.

Good to know

  • A text watermark drawn this way is part of the page content — it is not a security feature and can be removed by anyone determined enough.
  • Lower opacity keeps the underlying text readable; around 15–25% usually works well.
