Ceramic tile production is a very complex process. The production process is an assembly of chemical, mechanical, thermo-dynamical and other processes which must be finely tuned for good and successful production.In the production chain there are numerous ways for things to go wrong. Every failure directly reflects on the final ceramic tile. The final production phase is visual inspection, classification and packing of ceramic tiles. In most cases the last phase is based on human perception capability. Human resources as controllers in this phase are very unreliable. During hard working...
