Abstract
The volume of ink ejected from an ink jet printing apparatus during one cycle of operation for printing a dot upon a recording medium is controlled within that cycle of operation by operating the ink jet apparatus via the application of a pulse train having a periodicity equivalent to the dominant resonant frequency of the ink jet apparatus. An electrical signal in the form of an earlier pulse train is followed by at least one additional electrical signal or pulse having a time delay and an ink jet transducer is selectively gated on or off by the electrical signals.
