Try lemon oil.
Also try ' goof off' its for adhesives but sometimes works on stains.

try eucalyptus oil also some inks dissolve in milk / rum might go well in milk not sure about the eucalyptus oil / it makes a mess of the koalas / they get very dizzy.

I have found orange oil will remove some ink stains. I peel the orange and rub the outside of the skin on the stain, bend it a bit so the oil comes to the surface. try it on a hidden place first as it can leave an orange mark on more porous surfaces.
