Try this stuff. I've heard it works great but never used it personally.
I rarely get pigments on me or my clothes. If it does what the description says, it should take out tattoo pigments as well. India ink is fairly concentrated stuff.

You may be able to find a supplier that is less expensive, I did a simple search. Good luck!
