ABSTRACT:
A system for producing lithographic printing plates by image transfer from either a right way or a wrong way reading recording member, which comprise a conductive base having first and second register means thereon the register means being arranged and positioned respectively so that the first engages and locates an image receiving member and a recording member on the base and the second engages and locates an offset member on the base, the register means being spaced apart to allow access to the first register means while the offset member is engaged on the second register means, a roller having at least a conductive core arranged to move over the base outwards from the register means and return, and means to apply an electrical field between the roller and base and to change the polarity to prevent electrostatic image transfer during the outward movement of the roller and to cause electrostatic image transfer during the return movement of the roller.
