The registration board assembly for pre-press printing proofs and printing plates includes a substantially planar layer or registration board, a backing layer adjacent and affixed to the planar layer, and a cavity formed between the planar layer and the backing layer. A register pin extends through an aperture in the planar layer. An elastomeric member such as a rubber diaphragm is disposed within the cavity and biases a barrel portion of the register pin through the planar layer aperture. The elastomeric member is mounted so that it is removable and replaceable. One way of mounting the elastomeric member is to provide a hole in the backing layer through which the elastomeric member is pulled to remove it. A new elastomeric member is then pushed through the backing layer hole. In a second embodiment, a threaded plug in the backing layer holds the elastomeric member in place. The threaded plug is removed to replace the elastomeric member. In a third embodiment, the backing layer is fastened to the registration board by one or more screw fasteners. The fasteners are removed to remove the backing layer when the elastomeric member is to be replaced.
