(57) The invention relates to a printing head (1) for decorating tiles (11), comprising at least a hollow element (2), internally of which a conduit (3) is afforded, destined to contain pressurised glaze (4). The conduit (3) exhibits at least an outlet nozzle (6) for the glaze (4). An obturator (9) is associated to each nozzle (6) and is mobile between a closed position of the nozzle (6) and an open position of the nozzle (6). The obturator (9) is activated by a relative piezo-electric actuator (10), arranged internally of the conduit (3), to which it is solidly constrained.
