Abstract

A loading table for flexographic printing plates is disclosed wherein pneumatic suction is employed to secure the printing plate to the loading table and pneumatic pressure is employed to reduce the friction when conveying the printing plate from the loading table to an imaging cylinder. The loading table comprises a plurality of openings connected to a reversible pump. Pneumatic suction or pressure from the pump is transferred to the printing plate via the openings in the loading table. While immobilized on the loading table with pneumatic suction, the flexographic plates can be prepared for imaging by peeling the protective coating from the active layer. The coupling of the plate to the loading table surface facilitates such preparatory steps without excessive handling of the plate. After preparation, the pneumatic pressure is reversed and a thin layer of air is created underneath the plate reducing the friction and permitting simple transfer of the plate to an imaging cylinder for further processing.
