He prepares his own colours from dry pigment and an emulsion composed of water, egg, linseed oil, dammar and a few drops of dammar and a few drops of lavender oil for preservation. Occasionally he uses watercolour on paper.
His most usual method is that of engraving by photopolymerisation, which is very close in itself to that of the polymerization, which is very close in itself to etching, but differs in that it uses which differs, however, in that it uses a polymer plate instead of a copper and acid plate. acid, a polymer plate (a type of plastic) "etched" with water and and ultraviolet light. The actual printing is done in exactly the same exactly the same way as for etching.
