A printing ink composition comprising: (a) a dispersion of about 10-25 wt. %, based on the weight of the composition, of a pigment in about 40-90 wt. %, based on the weight of the composition, of a C7-C40 oil; and (b) about 0.1 to 5.0 wt. %, based on the weight of the composition, of a soap of a tall oil fatty acid. The printing ink composition has the unique capability of being utilized in lithographic printing processes utilizing tap water rather than aqueous fountain solution in the dampening system of the press.
