    Abstract: An electrographic recorder is described which lays down a line of electrostatic charge on a charge retentive surface of a strip of electrographic recording paper. In one embodiment, the transverse position of the line charge image on the recording strip is representative of the amplitude of the signal being recorded. Plural inkers each dispensing a different color of charged pigment are arranged to ink charge images within separate strip-shaped zones of the recording strip. Thus, the inked electrostatic image will have a color dependent upon the amplitude range it happens to correspond to at any position taken longitudinally along the strip. The transverse position of the boundary between different colors is adjustable by sliding or pivoting the inkers, whereby the different colored amplitude ranges are made adjustable. In a second and third embodiment a multichannel recorder or printer is described wherein the signals corresponding to the different channels are each recorded in their own separate strip-shaped zone of the recording paper. Each separate recording zone has its own separate inker with pigment of a different color than that of its neighbors.
