Abstract:
1. A pre-press flexographic plate laminator for laminating a masking film onto a pre-press flexographic printing plate, the apparatus comprising: a support gantry independently supporting a carriage, including one or more lamination flexure plates, to minimize lateral distortion to a flexographic printing plate and masking film during lamination; a lamination roller attached to the carriage, independently supported by the gantry, forming a nip with a vacuum table to apply a balanced, non-distorting optimized lamination force (F a plow adjacent the nip to remove a cover sheet from the pre-laminate flexographic printing plate while applying the masking film; a center screw attached to the gantry to move the lamination roller along two side rails exposing the pre-laminated sheet to a uniform lamination force.
