ABSTRACT:
A molding plate for use in molding printing plates. A type-form plate bearing raised printing or indicia is coated with graphite and placed in a mold cavity with the printed surface being at an angle to the vertical and facing upwardly. A liquid thermosetting resin containing reinforcement is poured into the mold cavity and air is expelled from the upper end of the cavity. The resulting cured thermosetting resin plate has recessed printing impregnated with graphite and serves as a molding plate for forming printing plates from rubber or other materials.
