Lithography: a planographic (flat surface) printing process that makes use of the immiscibility of grease and water
Alois Senefelder was a German actor and playwright who invented the printmaking technique of lithography in 1796.
After problems printing his play Mathilde von Altenstein forced Senefelder into debt, he experimented with a novel etching technique using a greasy, acid resistant ink as a resist on a smooth fine-grained stone of Solnhofen limestone. He then discovered that this could be extended to allow printing from the flat surface of the stone alone, the first planographic processin printing.
Senefelder was also able to use the potential of lithography as a medium for art because lithography allowed the artist to draw directly onto the plate with familiar pens.
Alois Senefelder’s contribution ranks alongside William Ged’s invention of stereotyping, Friedrich Koenig’s steam press and Ottmar Mergenthaler’s linotype machine in its innovative effect. His invention made printing more affordable and available to more people, and it was important in art and newspaper printing.
