  • Patent number: 11639069
    Abstract: A process for mounting a printing plate on a carrier sheet, including disposing registration indicia on the plate, placing the carrier sheet on a cutting table of a cutting system, mounting the plate to the carrier sheet, detecting absolute coordinates of the registration indicia; and cutting the carrier sheet along a cut line having absolute coordinates generated based upon the detected absolute coordinates. A related system includes the cutting system with the cutting table, a camera for detecting the registration indicia, a processor, a cutter, a controller, and a computer memory programmed with instructions for instructing the controller to detect the indicia, calculate the absolute coordinates for the cut line based upon the detected absolute coordinates and stored relative coordinates for the cut line, and cutting the carrier sheet along the cut line. Computer readable media containing such programmed instructions is also disclosed.

  • Patent number: 7000543
    Abstract: A method and apparatus to aid the loading and unloading of flexographic plates to and from an imager. The apparatus includes a magazine containing a plurality of compartments each for holding a single flexographic plate, the compartments arranged vertically, and movable in a vertical direction, a lifting mechanism to lift and lower the compartments; and a control system to control the lifting and lowering by the lifting mechanism. The control system is such that a particular compartment is moved from its rest vertical position at a rest horizontal position to a loading vertical position and a loading horizontal position at which the particular compartment is at a height for loading onto the imager. The loading is automatic and in the case that the plate includes a protective sheet thereon, the loading includes removing the protective sheet from the plate.
