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.
