Bonnet was a leading exponent of two-colour and three-colour crayon engraving in Paris, and the inventor of the pastel engraving technique which required a greater number of plates. He published the method in a manual, entitled Le Pastel en gravure, invented and executed by Louis Bonnet.

One of his specialities was to print gold imitation frames around his pastel engravings; these prints he usually signed as L. Marin, rather than as Bonnet, as in Provoking Fidelity, after the painting by Marc Antoine Parelle. The painting has Parelle’s signature and the date on the dog’s collar, a detail not included by Bonnet, though Parelle’s authorship is clear in the lettering on the print.
