Abstract

An offset lithographic printing process utilizing a water-based printing ink.
The process is conducted at a relative humidity of 75-100 % and preferably at a temperature of 10-30 °C. A useful water-based ink comprises water; a macromolecular binder which: (i) is optionally present and is of the type which is water-soluble, regardless of the pH of the water phase, (ii) is present and is of the type which is water-soluble only at a pre-determined pH value, or (iii) is optionally present and is an aqueous emulsion; a pigment; and a re-wetting agent. A nonionic surfactant may also be present in the ink.
