  • Ink drop control system with temperature compensation
    Patent number: 4860027
    Abstract: A method and apparatus are disclosed which provide feedback control of ink viscosity in a drop marking system. The ink flow between two selected points is monitored and compared against a reference value by an electronic controller such as a microprocessor. In the event that a flow time deviation is sensed, appropriate action is taken to change the flow time. A temperature sensor input to the controller permits temperature compensation to maintain ink composition substantially constant.
