A double-sided exposure apparatus is disclosed. The apparatus incorporates a phototool die set that provides high accuracy, speed and smooth operation with minimal particulate contamination of the exposure zone while allowing conventional work piece transport and handling. Upper and lower die halves are supported by four corner posts, guided by precision preloaded bearings to obtain high accuracy in front to back registration of art works maintained in the upper and lower die halves. The die halves are reversibly separated by upward motion actuated by a closed loop servo motor and lead screw system simultaneously elevating the four corner posts to which the upper die half is rigidly attached.

A double-sided UV exposure system comprising: an exposure cabinet having a base and a support frame; a phototool die set having an upper die structure having four rod caps mounted in a spaced quadrilateral relation thereon and a lower die structure rigidly mounted to the support frame and having four bearing blocks mounted thereon in said spaced quadrilateral relation; an elevation structure having four closed end bearing blocks mounted thereon in said spaced quadrilateral relation; means for reversibly raising the elevation structure from a first lower position to a second upper position; and four rods removably supported in said closed end bearing blocks, said rods extending through said bearing blocks mounted to the lower die structure and received in said rod caps mounted to the upper die structure whereby raising the elevation structure from said first position to said second position raises the upper die structure from a first closed position to a second open position.
