Abstract
A non-petroleum base newspaper offset printing ink comprising a blend of Gilsonite (uintaite) flakes and tall oil fatty acid together with carbon black pigment. The proportions of the Gilsonite and the tall oil fatty acid may be varied, as viscosity requirements change due to differences in press speeds, newsprint characteristics, and the like. The ink thus has readily adjustable viscosity, together with an enhanced flow and penetration characteristics, while being extremely economical to manufacture.
