Proper chain of custody is an essential element of data defensibility. That being said, I need to know the legality of using red ink on an official document. Basically, the sample ID number we use is written in red indelible ink so it's easy to differentiate between it and all of the other text on the chain of custody. It makes filing and retrieving much easier! I've searched online and I can't find a conclusive answer. The bulk of what I'm seeing suggests that it's perfectly legal but was frowned upon in the past because it didn't photo-copy or scan as well. Does anyone know of a code or statute that actually mandates ink color? I'm getting tired of hearing “only blue or black ink is acceptable” from the teeming masses without anything to back it up!
Thanks!
PS, I'm in South Carolina
