Zusammenfassung:A method of lubricating a sheet of material includes moving the sheet along a first direction and operating a print nozzle to deposit a lubricant on the sheet while the sheet is moving along the first direction. The print nozzle ejects the lubricant in a second direction that is transverse to the first direction and toward a first side of the sheet. The method includes charging the lubricant so that the lubricant ejected from the print nozzle is in the form of charged droplets and applying an external electrical field between the print nozzle and the sheet to attract the charged droplets to the sheet.
