Invented by Bavarian author Aloys Senefelder in 1796,lithography is a method for printing on a smooth surface.
Lithography is a printing process that uses chemical
processes to create an image. For instance, the positive part
of an image would be a hydrophobic chemical, while the
negative image would be water. Thus, when the plate is
introduced to a compatible ink and water mixture, the ink
will adhere to the positive image and the water will clean the
negative image. This allows for a relatively flat print plate
which allows for much longer runs than the older physical
methods of imaging (e.g., embossing or engraving).
