Abstract (en)
[origin: EP0468068A1] The supply of ink in a print head for ink printers takes place by means of a channel structure which comprises single channels 4, 5 located in two planes 6, 7; the direction of the single channels for example 4 in one plane e.g. 6, and that of the single channels for example 5 in the other plane 7, are offset by an angle; the openings 9 which are produced in the sectional area of the single channels 4, 5 form both a flow connection, with favourable flow properties, and an active ink filter integrated in the print head.
