UV ink

[Impractical Cartographer]

I'm thinking about using ink that is visible under ultraviolet light on maps.
You can see the effect in the video.



However, I am not satisfied. The ink is very difficult to calligraph with, it often spills and stains.
My experiments are ongoing and I'll let you know when I match the paper to the ink.

Have any of you tried something like this? Can you recommend me a particular type of ink?

'love the idea ! In this specific case, this bad ink also adds something very natural and immersive with its stains, as if used with clumsy hands...
I personally use the Noodlers Ink Blue Ghost invisible ink and had good results with it for drawing (can't say for calligraphy). I use it both with quill and in fountain pens, with no major trouble.

cool idea. Personally I've only use a big marker with it for a murder mystery at my old job. Love the thought of using it for a map
