The present invention is directed to a printing composition, in particular, a paste printing ink vehicle for effecting the setting of a paste printing ink by penetration into a substrate, the vehicle utilizing a vegetable oil fatty acid esterified with a simple alcohol or glycol as a solvent. The use of the esterified fatty acid as a solvent in the printing ink vehicle enables the production of novel petroleum distillate free paste printing inks having characteristics substantially similar to that of conventional petroleum distillate based printing inks.
