Abstract: An industrial printhead (100) comprising a flow channel enclosed in a chamber, wherein the flow channel (102) has at least one fluid inlet (102a) and at least one fluid outlet (102b), wherein the flow channel is resonated, in use, by a vibration distributor (104) comprising a mass resonator (103), piezoelectric exciter (108) and wave concentrator (110) arranged in an axial configuration.

Abstract: Method for producing a digitally printed decorative coating on a solid surface, comprising the steps of: applying solid pigment dye (2) to the surface (1) and treating the coating such that the treatment results in the setting/hardening of the coating, where at first the dry surface (1) is evenly coated applying solid pigment dye (2) at least over the surface portion where the coating is to be applied, in a subsequent printing operation liquid is applied to the surface (1) coated with dry pigment dye (2), thereby temporarily fixing the solid pigment dye (2) to the printed-on surface portions, and before performing the treatment resulting in the setting/hardening of the coating, removing the non-fixed portion of the solid pigment dye (2) from the surface (1).
