Abstract
In an ink jet printer having a plurality of ink jet channels which are individually controllable to produce ink dots on a printing medium, crosstalk is reduced by activating each odd numbered channel in alternation with each even numbered channel, while offsetting the orifices of one group of channels from the other to compensate for the time difference between activations, and the voltage supplied to excite the channel transducers is varied as a function of the number of channels simultaneously exited to maintain a fixed excitation voltage across each transducer.
