Lithography

特許 係属中 Lithography (from Ancient Greek λίθος, lithos, meaning "stone", and γράφειν, graphein, meaning "to write") is a method of printing originally based on the immiscibility of oil and water.[1] Printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by German author and actor Alois Senefelder as a cheap method of publishing theatrical works.
