FIELD: printing industry.
SUBSTANCE: invention relates to jet printing head, and more specifically, to head having holes for ejection of various ink drops. Jet printing head ejects ink supplied through hole of ink supply from multiple ejection holes, accordingly connected to channels for ink, having different resistance to flow, using energy generated by multiple elements of electric heat converters that correspond to multiple holes of ejection. At the same time each of multiple ejection holes is arranged so that centre of each of multiple ejection holes is located further from hole for ink supply to centre of according element of electric heat converter than each of multiple ejection holes.
EFFECT: invention is developed for improvement of forward sending ink drops flying in direction of ejection, improved accuracy of ink drops hitting the target for improved quality of image and increased speed of printing.
