A suction cup system facilitates the holding and manipulation of sensitive objects such as printing plates without scratching, marring or damaging surfaces of the objects. The system has a flexible thin sheet made of polyester or similar material. The flexible sheet is stretched over the flexible contact flange of a suction cup and supported in position by a relatively rigid frame. The flexible sheet contains at least one aperture communicating with the interior of the suction cup. The apparatus is brought into the vicinity of the object, with the exterior surface of the flexible sheet in contact with the object. A vacuum line acts to create suction force between the suction cup and the object via the aperture. As the vacuum increases, the flexible contact flange flattens and slides across the interior surface of the flexible sheet rather than the sensitive surface of the object. The movement of the flexible suction cup's flexible contact flange does not scratch, mar or damage the object.
