I work w Copic markers and I love them so much. However, I have found some markers don’t scan well which makes sense cause of things like highlighter yellow. If you don my know highlighters don’t scan intentionally so you can copy documents without the yellow color showing up on them scan.

RV & Y are most often the colors that don’t scan so I have made a grid of the markers I own.

RV04 & Y06 glow under black light which is cool but can mess w a piece if you are highlighting parts w black light and the yellow or pink are not the colors you want to glow.
