Lecture - Vol. He traced the introduction of Lithography in India and also discussed about its impact on the appearance of the vernacular printed books.
Lithography literally means writing or drawing on stone.
Various methods were used to produce books lithographically , but in practice just two methods predominated. A sheet of paper in a frame was then lowered onto the stone and an impression obtained either by rolling a brass cylinder over the paper or by using a proper press. When the required number of copies had been printed, the stone was polished clean removing all trace of the letters or design and it could then be reused. Alternatively, if the same text were thought likely to be reissued within a specified period of time, the stone with letters intact would be stored away until reprinting took place. The stones were ideally between 2 and 2.5 inches thick and could be reused in this way upto 30 or 40 times.
