Tips for Best Results

• Use semi-transparent text (around 30-50% opacity) for a professional look that doesn't obscure content.
• Larger font sizes work well for single-page documents; smaller sizes are better for multi-page reports.
• Watermark text is rendered diagonally across each page for maximum coverage.
