  • Patent number: 4322161
    Abstract: An open face vacuum light table with an associated overhead high intensity light source is provided with a movable, preferrably pivotable, framer structure capable of overlying either of two table surface areas, at least one of which is provided with an apparatus, for example a vacuum grid, for drawing lithographic work pieces into close contact for light induced image recordation on film or other light sensitive receiver. The frame may carry a clear sheet of stripping base material that also serves as the vacuum completing face of the vacuum grid. The table is provided with stripping pin grooves about the perimeter of the entire table, an entire sub-area, partially around the table or a sub-area. Apparatus for maintaining one face of the pivoted frame in coplanar relationship with either of the table areas over which the frame is located may include an elevator mechanism associated with one or both table areas or an eccentric pivot between the frame and table.
