Disclosed is a form of electrostatic printing wherein (1) an electrostatic image is applied to a plastic gravure roll by any imagewise charging device and (2) the gravure roll is used as a simple liquid ink selective wetting device. While the gravure cups are ideal electric charge receptors, in order to work with aqueous inks, the cups must be electrically isolated from each other. One may use silicone oil on the plastic surface between the cups to keep it from being wet with aqueous ink and thus avoid the erasure of the elastrostatic pattern by the aqueous ink.
