Abstract
A multiple print head for a continuous ink jet printer has its individual ink jets produced by an electrostatic field as an array of cusps along a straight edge to which the ink is continuously supplied. The straight edge is produced by folding an electrically conductive foil to give a surface less prone to corona discharges.
