Probably the most effective way would be distillation: heat the water, then cool the steam into a separate container. In the end you will have ink or residue in the original container and water in the second container. This will work well with India ink, for example, which is a suspension of carbon particles (soot).
Some inks may have a component of alcohol or some other volatile liquid which will evaporate at a lower temperature than water. In this case you will have to use fractional distillation. For example, ethyl alcohol boils at 70 degrees C; if this is an important component of the ink you will have to heat the liquid to 70C, condense away the alcohol, replace the catch-flask with a new one and then boil off the water. When that's done, replace the alcohol in the concentrated ink in the first flask.

Distill away the water by heating the mixture to boiling, then trapping the cooling, purified steam in distillation tubing.

Let the water evaporate or boil it off.

put a charcoal in it and heat it until it boils. then use a filter paper to filter it.
