have you tried hairspray? it's odd sounding advise, but it works! In my experience, aeresol cans, as well as non-aeresol, pump type sprayers either one work. saturate the stained area with hairspray, then daub stain. ink begins lifting on contact, and with hairspray re-applied as needed, you can remove entire stain with patience.
To easily lift ink from your couch is to use hairspray and then slowly dab it with a paper towel until the ink and hairspray absorb into the paper towel.
Crazy as this may sound non-aerosol Hairspray should remove the stain. Spray some on the ink, then use an old tooth brush to scrub the stain out. The fabric should be good as new.
