litteracarolina OP , 1 month ago @medievodons @histodons @historikerinnen Here are some images I took just now of ordinary ballpoint on paper, the first with UV and the second with normal light. Great definition on the ink edges and paper fibres. Stroke of a ballpoint pen on paper under normal light. The whole image is reddish purple in colour.
