During 1980s I worked hard to study the "Grignotage" process from a theoretical and technical point of view. I found this descriptive term in a photographic encyclopedia. I decided to investigate the topic and process of the technique. After an intense work, I realized that the photographic technique of the "Grignotage" is close to the graphic engraving. Then I experimented with the principle of the same chemicals used until I got the result I was looking for. The "photographic engraving technique" was finally brought to fruition. From that moment on, this type of experimentation gave me great satisfaction and brilliant aesthetic results. Starting from a specially treated print (optimal results I obtained them using Iford papers such as: Galerie and now Ilford Hanemüle MG ART 300 and Kentmere papers) I apply the Grignotage process and then to the conservative treatment of the press. Many of the prints after the Grignotage process have been further processed with toning processes (pyrocatechin, monosulfide and selenium) and Polaroids are applied on them with the transfer technique.
