1. A method for decorating in thickness a ceramic slab, comprising the following steps:
preparing, on a decoration surface, a first soft decorated layer of ceramic material endowed with a decoration;
progressively transferring, by deposition, the soft decorated layer from the decoration surface to a first deposition surface, situated at a lower height than the decoration surface, thus progressively forming on the first deposition surface a second soft decorated layer which has a head and a tail, the head being formed by the ceramic material that is deposited first on the first deposition surface, the tail being formed by the ceramic material that is deposited last on the first deposition surface;
progressively transferring, by deposition, the second soft decorated layer from the first deposition surface to a second deposition surface, situated at a lower height than the first deposition surface, starting from the tail of the second soft decorated layer, thus progressively forming on the second deposition surface a third soft decorated layer.
