An ink composition for printing onto the surfaces of glass or other glazed ceramic surfaces by jet printing in which the preferred formulation for the printing ink composition comprises 2 - 20% by weight of a linear novolac resin, 0.6 - 3% by weight of an alcohol or water and alcohol soluble dyestuff, 3 - 7% by weight of an evaporation retardant in the form of a glycol ether or glycol ester, with the remainder water and alcohol, with the water present in an amount up to 50% by weight of the alcohol and which may contain a soluble ionizable salt when the electrical resistivity of the ink composition exceeds 2000 ohm/cm.
