A water based ink composition which can be used effectively in various ink jet type printing arrangements and on a variety of predetermined substrate surfaces. Such ink composition being resistant to smearing and running when contacted by water after application and drying on such substrate surfaces. This water based ink composition comprising a dye material, having a predetermined color, which is present in the ink composition generally in a range of between about 0.1 weight percent and about 10.0 weight percent. Water is present in such ink composition generally in a range of between about 50.0 weight percent and about 80.0 weight percent. There is a substantially water compatible organic solvent compound for dissolving such dye material therein. The organic solvent compound is present in such ink composition generally in a range of between about 10.0 weight percent and about 40.0 weight percent. Such ink composition exhibits a surface tension generally in a range of between about 20 dynes and about 50 dynes and a viscosity in a range of between about 1 centipoise and about 50 centipoise.
