BONNET LOUIS-MARIN 1736-1793.
French engraver and publisher. He came from a family of artisans and owned his training in engraving to his brother-in-law, the engraver Louis Legrand (1723-1808). Through Louis Legrand, Bonnet became the pupil of Jean-Charles François in 1756, a year before the latter discovered the " crayon manner " technique of engraving, designed to reproduce the effect of a coloured chalk drawing. Around the end of 1757 Bonnet used the new technique to engrave a Cupid (Hérold N°2A) after François Eisen. Gilles Demarteau, a rival of Jean-Charles François, enticed Bonnet to join his workshop and learnt the technique from him.
Bonnet engraved some 15 plates for Demarteau, and in 1760 he set up his own shop. During this period he strove to perfect the crayon manner by producing prints using several different plates, each inked with a different colour. Initially, he tried to produce drawing executed in black and white chalk on blue or buff paper; to do this he had to make a white ink that would not yellow with age. He was the first to use points of reference to print several plates one on top of the other. He also experimented with aquatint-like techniques designed to reproduce wash drawing.
It was in his workshop that Jean-François Janinet produced his first two coloured prints: the Procurator and the Tailor in the wash manner. He also invented a method of printing frames in gold ink aroud his works. He exploited the contempory fashion for things English by publishing stipple engravings with English titles and explanations.
