A lithograph is a type of printmaking process that involves creating images on a flat surface, typically a limestone or metal plate, using a special greasy material to draw the design. The principle behind lithography is that oil and water do not mix. Once the design is drawn, the plate is treated with chemicals to ensure that only the drawn areas attract ink. When ink is applied to the plate and pressed onto paper, it produces a print of the original design. This technique, invented in the late 18th century, is prized for its ability to reproduce detailed and artistic works.
