Abstract: A novel ink formulation, especially useful in Driography printing, is disclosed. The ink formulation comprises a basic planographic printing ink vehicle, a pigment, a modifying varnish and a flow control agent to provide an ink, especially suitable for use in Driography, which exhibits desirable hangling-viscosities under ambient conditions, improved rheological properties under severe press-operating conditions, and provides printings having sharp delineation, fidelity and excellent reproducibility in depth of color tones in long press runs. The basic printing ink vehicle may be a vehicle designed for either sheet-fed or heat-set printing systems. The novel ink formulation is designed to have a high viscosity and avoid becoming pseudoplastic in its behavior at higher press temperatures, which generally can range from about 85.degree. F. to 125.degree. F., and preferably, avoids becoming pseudoplastic at temperatures up to about 140.degree. F. or more.
