ABSTRACT:
Systems and methods for delivering ink by controlling a pressure of the ink. A vacuum or partial vacuum is maintained at an ink reservoir that supplies ink to one or more print heads. As the temperature of the inks or of the printing system changes, the pressure of the ink experiences a corresponding change. The printing system is equipped with temperature sensors to detect the temperature of the ink, the print heads, or the printing system. The temperature data is processed and an adjustment is made to the partial vacuum maintained on the ink reservoir to accommodate changes in temperature. The temperatures are repeatedly sampled to ensure that the pressure of the partial vacuum is properly maintained for current temperatures.
