The nozzle mounting has two opposed faces with at least one orifice (17,28,38,48,58,78) for ejection of ink, communicating with one of the faces, the internal face, and coming into contact with an ink chamber (200,400). The other of the faces is subjected to a non-wetting treatment and has an orifice surrounded by the non-wetting surface. The latter is adjacent, in the area away from the orifice to at least one wettable zone (19) situated at a medium distance from the edge of the orifice between twice and thirty times the diameter of the orifice. The mounting can have a pallet (14,27) pierced with the ink ejection orifice and a support (11,20) for the plate, with one face of the plate totally non-wetably treated. |
