FIELD: pray printing, in particular, narrow-spray printing head.
SUBSTANCE: the spray printing head (100) has four column matrices (61) of ink drop formers configurated for monochromatic single-pass printing with a printing resolution having a pitch of the points of the carrier axis that is less than the pitch of the column nozzles of the ink drop formers. The spray printing head has high-resistance heating resistors and control circuits , which are configurated so as to compensate for the parasitic resistance introduced by the power supply routes (86a, 86b, 86c, 86d).
EFFECT: provided compactness of the construction of the spray printing head at a great number of ink drop formers.
