Lithography

Lithography (from Greek λίθος - lithos, 'stone' + γράφειν - graphein, 'to write') is a method for printing using a stone (lithographic limestone) or a metal plate with a completely smooth surface. Invented in 1796 by German author and actor Alois Senefelder as a cheap method of publishing theatrical works, lithography can be used to print text or artwork onto paper or other suitable material.
