Abstract

To program or selectively image or erase a printing form (9) of ferroelectric material, in which the state of polarization of discrete areas of the printing form is controlled, utilizes an electron beam (12) generated by an electron gun (1, 3) which is impinged against a surface area (30) of the ferroelectric printing form. The beam is controlled in accordance with an image to be recorded, for subsequent printing, on the printing form; it is directed to the ferroelectric material by an electron beam focussing and accelerating system, for example similar to the system used in a television camera. The printing form (g) can be sealed with respect to an evacuated electron gun by a slide seal (14, 15) with a vacuum lock, or by a ferrofluidic vacuum lock (18, 20); or the electron gun can be closed by a Lenard window, or an end plate (27) with micro channels or micro ducts (26) therein. The intensity of the beam can be controlled by a suitable image control unit (32a).
