29.6 Tips and Notes
Placeholders in Text
Both stamps and watermarks support placeholders: - <TodaysDate> - Current date - <TodaysYear4>, <TodaysMonth>, <TodaysDay> - Date parts - <FileName> - Filename - <RuleId:N(RuleName)> - Extracted data
Text Color for Stamps
For good visibility and professional appearance: - Dark red (139, 0, 0): Classic for “PAID” or status stamps - Dark blue (0, 0, 139): Professional for approvals - Dark green (0, 100, 0): Positive for “Approved”
Watermark Opacity
| Opacity |
Effect |
| 0.1 - 0.2 |
Very subtle, text remains easily readable |
| 0.2 - 0.4 |
Clearly visible, slight readability impact |
| 0.4 - 0.6 |
Dominant, may impair readability |
Permanent vs. As Annotation
- Permanent: More secure, as it cannot be removed. Ideal for legal or final markings.
- As Annotation: More flexible, can be removed if needed. Useful for temporary markings or review processes.
Combination with Other Tasks
Typically place “Add Stamp/Watermark” before tasks like “Send Email” or “Copy File”, so subsequent tasks use the stamped document.
