In 1798, Czech inventor and artist Alois Senefelder invented the process of lithography. As a result of his experiments with calcium carbonate and greasy ink, he devised a method of producing multiple copies of his artwork and writings.
Senefelder also discovered an important benefit of lithography, whereby images printed on paper could be transferred back to another stone, preserving the original stone. This paved the way for 'ganging up' multiple images for printing.
