Programmable station and plant for the production of plates with chromatic effects

A station for a realization of coloring effects in a mix for a production of slabs, comprising:

• a working surface to accommodate a temporary support with a basic mix layer for the formation of a slab;
• at least one dye dispensing device for emitting dyes toward the working surface so as to deposit the dyes on the basic mix layer on the temporary support;
• a movement means for a relative movement of the dye dispensing device above the working surface;
• a control system connected to the movement means for controlling the displacement of the dye dispensing device on the working surface so as to follow trajectories along which the dyes are emitted toward towards the basic mix layer;
• at least one tool movable with the movement means to interact mechanically with areas of the basic mix layer for receipt of the dyes emitted by the dye dispensing device to achieve coloring effects in the basic mix layer;
• and
• at least one store for a plurality of tools and a means for controlled pick-up of a selected tool from the at least one store.
