What do you think?

A strong acid will do this - so I'd suggest iron(II) sulphate and water. In fact, you can see this very effect in action if you look at any old manuscript written with crown gall ink, which was made with tannins and iron sulphate solution. Where there were "blobs" of ink the paper usually has a hole.
