Bulk document watermarking

Purpose

1. Provides secure, consistent watermarking of large batches of property appraisal documents and reports.

2. Enables compliance, intellectual property protection, and branding for appraiser-generated files.

3. Reduces manual workload and errors by automating watermark placement across PDFs, Word, and image reports.

4. Ensures audit trails by embedding timestamps, user IDs, or confidentiality notices.

5. Facilitates bulk delivery or archiving, with documents watermarked dynamically by recipient or report type.

Trigger Conditions

1. Batch upload of appraisal reports to a cloud or local directory.

2. New report generation event from appraisal software.

3. Submission of files to a central review or QA folder.

4. Receipt of spreadsheet/CSV documenting required watermark styles per client.

5. Scheduled intervals (e.g., end-of-day bulk processing).

6. API call from client portal or CRM for on-demand watermarking.

7. User action in document dashboard, e.g., checkbox selection and “Watermark All” command.

8. Receipt of specific email subject or attachment in monitored inbox.
