The lithographic printing process is very versatile and used to produce a wide range of printed matter. The bulk of this falls into two main categories (i) publication and (ii) packaging. In commercial practice, most lithographic printing is accomplished by an offset process, that is by transferring the image from the plate to an intermediate roller on blanket and then to the substrate being printed. The basic principle of offset lithography involves mechanical damping of a printing plate which consists of an oleophilic image area and hydrophilic non-image area. The plate is then inked and brought into contact with a rubber offset blanket which under pressure, transfers the image to the required substrate (Figure 1).
