1702
Jacob Christoph Le Blon, an artist and businessman, was the first to produce a colour printing method to reproduce paintings for mass consumption. Being an artist he knew that the three primary colours, (red, yellow and blue) plus black and white could produce all other colours. So he utilised the three primary colours, with the paper supplying white and an overlay of the three colours producing black. He hand engraved the plates for each colour as well as for the image to be reproduced. Most of his commercial work was carried out in London and Paris.
