ABSTRACT:
In a continuous ink jet printer of the type in which drops can be deflected to a plurality of print positions, the path of undeflected drops is angled relative to the substrate 23 which is printed onto, so as to shorten the path of the most deflected drops. Since the most deflected drops are the least stable, this tends to increase print quality or allow greater printing speed. The plane of deflection of ink drops may be parallel to a circuit board 1 on which components of the print head are mounted, enabling a deflection electrode 15 and other electrodes to be formed directly on the circuit board, thereby reducing the number of components which have to be mounted separately onto the circuit board 1.
