Tips for getting PDF Watermark right
- Use a diagonal text mark for review copies so it's obvious but doesn't hide content
- Keep opacity low enough that the document text stays readable underneath
- Confirm the mark is applied to every page, not just the first
- A watermark is a deterrent, not protection — encrypt sensitive files too
