Abstract
A method of printing comprising applying a conductive developer to a imaged dielectric surface in the presence of an energising electrical image-defining field to form a master having conductive and relatively insulating areas defining the image, inking the said surface in the presence of a field of a polarity to urge the ink on to the surface to retain it at the relatively insulating image areas, and transferring the ink from the said surface to a receiving surface in the presence of a field of a polarity to urge the ink on to the receiving surface, and continuing inking the said master and transferring the ink to further receiving sheets.
