Five Prints of Flowers in Glass Vases, Anonymous, Jean Baptiste Monnoyer, Johan Teyler, 1688 - 1698
Johannes Teyler from Nijmegen was educated as a philosopher and mathematician, but also worked later as a military engineer. He invented a method for printing impressions in colour, for which he received a patent in 1688. The colours had to be applied to the copper plate by hand for each individual impression. Because this was very labour intensive, his colour printing process found little following.
