Best Practices
Redaction procedures vary by institution, but here are some best practices:
Only redact copies (paper or digital) to preserve the original.
Use a professional version of PDF software for the best results. Look for a redaction option for complete removal. See pages for Acrobat Pro and Preview for Mac .
“Reader” software tools such as blackout captions or changing fonts to white are not sufficient.
Covering scanned papers with tape or black marker may not totally block the image. Literally "cutting out" the text is the surest method.
Test your process before completing the task to ensure total removal. Look for shadows or images bleeding through.
