Lithography
Lithography involves the printing of an image from a flat surface. The technique, which was invented in the late eighteenth century, relies on the principle that oil and water repel each other. Traditionally employing a limestone slab that has been roughened or smoothed according to the effects desired, the lithographer draws directly on the surface with a greasy crayon or with a brush and a liquid ink called tusche. Drawings for lithographs can also be made on specially treated zinc or aluminum plates (hence zincography and algraphy). Next Page 1/3 |
