Abstract:
A process for producing duplicates in series of an object having a decorative three-dimensional surface (11) comprising a plurality of crests (12), or protrusions, each of which (12) having a predetermined thickness, or height (s). The process comprises, in particular the steps of introducing the object (1) in a container body (120) having a side containing edge (125) that protrudes, in use, beyond the object (1). Furthermore, a step is provided of distributing on the object (1) a first hardening material (70) suitable to cover the decorative three-dimensional surface (11) of the object (1) and a step of hardening the hardening material obtaining a mould (210) provided at the face oriented towards the object (1) of a three-dimensional surface (211) reproducing in negative the three-dimensional surface (11) of the object (I). A step is furthermore provided of distributing a determined amount of a second hardening material (80) on the surface (211) of the mould (210) obtaining a layer (300) of hardening material (80) of predetermined height. Once the layer (300) of the second hardening material (80) is hardened, a cast (315) of the object (1) is obtained having a decorative surface (316) reproducing the surface (II) of the object (1) comprising a plurality of crests (312) with thicknesses corresponding to those of the crests (12) of the object (1). Furthermore, a printing step of the decorative surface (316) is provided obtaining a printed decorative surface (317) and then a duplicate of the object (1).
