I've had good luck with De Atramentis Document Ink. Dries very quickly, won't smear when I set my beer can^W^W coffee cup down on it. I have been using it for years, and it hasn't screwed up my pen.
I don't know if it is as safe on fine pens as the article would want, but since I use it in a $30 Lamy, I'm not too concerned.
