Electrospray fog generation for fountain solution image generation

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...

Zusammenfassung:	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.
