The present invention constitutes a vacuum press for mounting and laminating graphic art objects such as photographs and the like. The press utilizes two pliable airtight membranes, a first membrane attached to and supported by a base frame and a second membrane positioned over the base frame, arranged to form an airtight chamber containing the workpiece. The second membrane is specifically chosen so as to have a contour-defining capability. Thus when the chamber is evacuated, exterior atmospheric pressure will collapse the chamber and compress the workpiece between the two membranes, and at the same time, the second membranes will image the upper surface contour of the workpiece so as to reveal any undesirable surface irregularities such as wrinkles or bubbles which might exist in the workpiece. This indication gives the operator an opportunity to remove the irregularities before mounting or laminating occurs. After the workpiece has been compressed, it is heated by one or more heating elements contained in the press to assist in bonding together the elements which make up the workpiece.
