Apparatus for marking objects (11) which are conducted past a marking jet discharging head (13) has a plurality of colour jet orifices (26) for producing dots defining a character. The orifices (26) are arranged in at least one row, and the head (13) is pivotable about an axis (21) perpendicular to the surface (20) to be marked, to vary the inscription height i.e. higher characters being produced in Fig. 4 than in Fig. 5. Discharge of dots is controllable so that upright characters can be produced irrespective of the pivoting of the head (13). The discharge orifices (26) can be arranged in two rows (see Fig. 7) to produce more compact characters. <IMAGE> |
