Abstract: An ink jet head, comprising:

a dispensing unit (2), provided with: a main circulation conduit (21) for circulating a ceramic enamel; two or more nozzles (3), placed in communication with the main conduit (21) and distributed along a main direction (X); at least one shutter (4), activatable to close or free said nozzles (3);
at least one actuator (5), arranged to activate the shutter (4); wherein the shutter (4) is movable between at least one closing configuration,
in which it is capable of closing all the nozzles (3), and at least one opening configuration, in which it frees at least one nozzle (3) to allow the emission of ceramic enamel.

Abstract: The invention relates to a method for the mass decoration of ceramic products, comprising the following steps: spreading, superposed on one another, a layer (L) of granular or powder material and a decorative layer (3) on a support surface (2); transferring the layer (L) from the support surface (2) to an accumulation belt (T1), contiguous and aligned to the support surface (2), which is located at a lower height than the support surface (2), wherein the accumulation belt (T1) is mobile in advancement at a speed that is different from the advancement speed of the support surface (2), so that a variation in the thickness and longitudinal extension of the layer (L) is produced; pressing the layer (L) and the decorative layer (3).
