Lenticular enamel in engravings! The paint does not cover the engravings, yet makes them noble. Indeed, the transparent range enhances the tracks followed by the engraving tool, originally designed in the design phase; three-dimensionality is obtained through excavation in the material, and a color filling, resistant to atmospheric agents. The result is superlative in the interpretation of nuances foreseen in the logos, or changes of tone. In depth, the metal, engraved with angles of geometric cut, gives right shadows and lights from any point of observation, thanks to the transparent enamel. Everything is done in the BERELUCE experimental research laboratory.
