Product Description Since 1862, Charbonnel has been manufacturing inks and grounds for intaglio and lithography. Charbonnel has been the choice for the most renowned artists of our time: from Renoir, Degas, Lautrec and Picasso to present day masters such as Rauschenberg, Hockney, Diebenkorn and Thiebaud. The pigments are chosen for their excellent light fastness and low acidity. They are then blended with top-quality oils and finely milled to ensure trouble-free printing and a lasting work of art.
