Printing inks are applied to substrates by printing presses of various designs and are divided into five categories according to the type of printing press. Major printing processes used by the industry are lithography (offset), letterpress, flexography, gravure and screen printing. Letterpress and lithographic inks are viscous and paste-like. Flexographic and gravure inks are extremely fluid and they are generally called liquid inks. On the other hand, screen inks are intermediate in viscosity between the liquid flexographic and gravure inks and the paste-like lithographic inks.
Vegetable oils are mainly used in paste inks; therefore the role of vegetable oils in paste ink formulations will be described.
