    Abstract: An electrospray apparatus and a method of operating the electrospray apparatus can include an array of emitters that can emit a fog of charged droplets, wherein the charged droplets can be produced in a carrier gas by the array of emitters and directed into a development zone of a charge image. Each emitter among the array of emitters can be implemented as a cone-shaped emitter. The array of emitters can be implemented as a cone jet electrospray micro-array that can produce a high liquid concentration of the charged droplets in the carrier gas. The charged droplets can comprise charged fountain solution droplets, and the charge image can be a fountain solution image that can be transferrable to a blanket for control and subsequent ink transfer to a receiving medium.

    Abstract: An electrostatic atomizer electrostatically atomizes a fluid into a charged spray, wherein the charged spray includes a plurality of charged droplets. The electrostatic atomizer includes a chamber forming an inlet and an exit aperture, wherein the chamber is configured for fluid to flow into the chamber from the inlet and to flow out of the chamber from the aperture. An emitter electrode is in liquid contact with the fluid in the chamber and injects an electrical charge into the fluid in the chamber. An impedance circuit is coupled to the chamber and configured to obtain a voltage difference between the emitter electrode and the exit aperture, wherein the voltage difference is at least a minimum voltage threshold.

    Abstract: A method and system for determining a density of a fluid is provided. The method is carried out using an electrospraying apparatus connected in the system. At a first step fluid is introduced into an emitter of the electrospraying apparatus. A voltage is applied between the emitter and a counter-electrode spaced apart from the emitter for a number of intermittent time periods, wherein the duration of at least some of the time periods during which the voltage is applied progressively decreases. The current between the emitter and the counter-electrode is measured for each time period during which a voltage is applied and the shortest time period for which a current reading is obtained is recorded. The shortest time period is used to calculate the density of the fluid in the emitter.
