Abstract

An imaging device (10) for a printing form (12), in particular in a printing unit (82) of a printing press (84), having at least one light source (14) and an imaging optics (18) for projecting the at least one light source (14) onto the printing form (12), at least one optical element (20), in particular a lens, of the imaging optics (18), being movable by way of an actuator element (48), and the imaging optics (18) including one sensor (24) for measuring the actual position of the optical element (20), the sensor having one coil (26) and at least one sensor target (28). The sensor (24) is assigned to a control element (66) for adjusting the position of the optical element (20) via the actuator element (48), so that a highly precise, dynamic positioning of the optical element (20) can be achieved.
