Continuous ink jet devices exhibit vibration and other effects caused by the need to perturbate the fluid medium and expel1 droplets of ink from an orifice. The fact that this may be done over a wide array, creates additional problems of standing waves and accompanying power nodes, if the operating frequency changes relative to the fixed mechanical dimensions of the array. The segmented drop generator 10 shown in the accompanying figure offers a means to eliminate or minimize a number of the effects inherent in the long arrays necessary to produce high resolution, page width images. The drop generator 10 has a plurality of separate structures 12 which house a plurality of ink channels 14, the number of channels being determined by system constraints. The separation between structures is minimal, with the constraint being the interval spacing between the streams in the array. The structure 12 spacing is the means to break up any lengthwise modes caused by the operating frequency.
