- nikanj 5y agoThe instructions we've used for years 1) Print it out 2) Cut out the parts you want to redact 3) Scan the paper This might be more work, but 1) It's easy enough for anyone to understand 2) It's really, really hard to get wrong
- jsty 5y agoA bit easier but more or less as effective is redact on pc -> print -> scan Pretty much as infallible and saves a huge amount of scissor time.
