So we're going Warded Man, ARR-style? I approve.
I think the one thing that I would have to argue for utilizing the Arcanima styled magick would be that the body is not flat. Technically any design drawn on the skin is rounded, as well as slightly obscured by the veins, muscle, fat, etc. even if one were to find an imaginary flat part on their body. When coupled against the precision with which one can be assured is necessary to enact these spells (Wet book = Ruined book), I just don't believe it would be theoretically possible to pull it off.
Perhaps you can get a weaker effect than that of a precise algorithm, or a chance for it to fail? I also don't think you could put it on many places of the body as well, we don't have too surfaces that can even remotely be considered flat. Of course, you could always just put the "REASONS" stamp on it, sport a full sleeve of tattoos, and I'll see myself out for over-analyzing the idea.
