ABSTRACT:
A liquid jet recorder which includes at least one jet nozzle which is connected to a pressure medium conduit for the ejection of an electrically-conductive recording liquid onto a recording carrier, and which includes at least one control electrode connected to a signal source for modulation of the liquid jet in the context of carrying out spot or point wise recording. The liquid jet recorder of the above-mentioned type, which in a simple manner facilitates that the intensity of a recording color may be controlled within a predetermined range of accuracy. The signal source comprises a number of impulse generators which correspond to the number of desired color steps for each image point, whose impulse sequences are in synchronism, which possess equal impulse amplitudes and may be differentiated from each other with respect to the sensing relationship of the color steps; and including means for connecting the required impulse generator required for the recording of a desired color step on an image point to the associated electrode, while providing an identical recording time for all image points.
