Is the ink a pure substance or a mixture?
Although this question is vague (what is a pure substance) I suspect that the best answer is, "No". To prove this take a black felt tip or roller ball pen (not an oil based ball point pen) and draw a line on a paper towel. Now wet the paper towel near the ink mark so that the water is absorbed and is drawn through the towel and across the ink. You should see the ink diffuse with the water and see the various color in the ink diffuse at different rates. This is called chromatography. You should see ink colors of blue, purple, red. If you google for chromatography you'll find a variety of simple home experiments.
