When a dot of ink hits paper it soaks in a little. This holds the ink in place and helps it dry quicker. The dot of ink also spreads out a little as it soaks in and dries. The drops of ink hook together forming better coverage. Printing onto a metal surface might require smaller dots but denser coverage. You are very close if the ink is drying? Is it?
