Description
Oil-based inks applied as a thin, highly pigmented films to the printing paper using the lithographic process. Litho inks, also called litho varnishes, were composed of a heat-bodied linseed oil. The ink is smooth and homogeneous with finely ground particles. Litho inks vary greatly in their viscosity depending on their degree of polymerization and are sold in light, medium and heavy grades (Mayer 1969). The ink and pigments must be compatible with the vulcanized rubber used on many printing cylinders. In the 19th century many inks were diluted and extended with inexpensive petroleum products (Mills and White 1994). During the 20th century, numerous synthetic resin formulations came into use.
