Abstract:
A method of electronic printing onto a glass substrate, the substrate having a front surface and a rear surface and not including a conductive ground plane affixed to or deposited on the rear surface thereof, the method comprising the acts of:arranging a ground plane behind the glass substrate and holding the glass substrate to the ground plane during subsequent processing steps, wherein the glass substrate is held to the ground plane by a vacuum system;applying an even charge to the front surface of the glass substrate to provide an even surface charge of a selected polarity on the glass substrate;applying a selected charge pattern to the front surface of the glass substrate of a polarity opposite to that of the even surface charge to form an electrostatic latent image thereon;transporting a liquid electrostatic toner from a toner source to the electrostatic latent image on a donor roller;applying the electrostatic toner to the electrostatic latent image via the donor roller to provide a toner image on the glass substrate;fixing the toner image on the glass substrate at a fixing station; andreleasing the glass substrate from the ground plane.
