Method for making ceramic slabs or tiles

Abstract

This is a method for making ceramic slabs or tiles. It comprises the following steps: placing a soft layer (sl) of granular or powdered ceramic material on a support plane (p); pressing the soft layer (sl) to obtain a compacted layer (cl); firing the compacted layer (cl); before pressing, applying an identification mark (m) to the soft layer (sl), the identification mark (m) having an optical contrast with the soft layer (sl) so as to allow optical detection of the mark (m); after pressing, acquiring an image of the mark (m); processing the image of the detected mark (m) in order to control one or more operational steps subsequent to pressing.
