ABSTRACT:
A method an apparatus for maintaining a predetermined ejected ink drop volume in a continuous inkjet printer is provided. An ink parameter, for example, temperature, velocity, flow rate, viscosity, is monitored. A time period between activation control signals provided to an ink drop forming mechanism is varied in response to a change in the ink parameter. The apparatus includes an ink parameter monitoring device which provides an input signal to a controller. The controller varies the time period between activation control signals provided to the ink drop forming mechanism.
