The printing plates, whether made of metal or stone, can be made using a photographic technique known as photolithography. The design is copied or generated as a structured polymer coating bonded to a pliable plastic or metal plate in current commercial lithography.
Fine art printing still uses this ancient method. Finally, the ink would be transferred to a blank sheet of paper, resulting in a printed page. Only the gum-treated areas absorbed the water, making them even more oil-repellent.Ī lithograph of Charles Marion Russell’s The Custer Fight (1903), with the range of tones fading toward the edges See file page for creator info.Īfter that, oil-based ink was used, which would only adhere to the original sketch. The stone was subsequently treated with a mild acid and gum arabic combination, which made the sections of the stone’s surface that weren’t coated by grease more hydrophilic.
Initially, the picture to be produced was drawn onto the surface of a smoothened and flattened limestone plate with a fatty material such as wax, grease, or oil. Text or images can be printed using lithography on either paper or other materials.Ī lithograph is a lithographic print however, the name is exclusively applied to fine art prints and a few other, largely older forms of printed materials, not to those produced by current commercial lithography. It was devised in 1796 by Alois Senefelder, a German playwright, and performer, and was first used primarily for orchestral music and maps.
The printing is done on a smooth-surfaced stone or metal plate. Lithography printmaking is a planographic technique that was predicated on the immiscibility of water and oil at the time.
