Zincography was a planographic printing process that used zinc plates. Alois Senefelder first mentioned zinc’s lithographic use as a substitute for Bavarian limestone in his 1801 English patent specifications.

In 1837-1842, Eugène-Florent Kaeppelin perfected the process to create a large polychrome geologic map.
