PDF Watermarking Best Practices
- For business agreements, a diagonal 45° angle with 25-35% opacity provides strong security without impeding reading.
- Use red stamp color for time-sensitive review materials and subtle slate gray for draft documentation.
- The watermark is applied across every page automatically, maintaining consistent scale regardless of page orientation.
