ABSTRACT:
This invention provides an apparatus for positioning and securing a printing plate to a printing plate cylinder. Such apparatus includes a sheet member having a bottom surface portion engageable with a working surface of such printing plate cylinder and an axially opposed upper surface portion. A plurality of apertures are formed through the sheet member across a width dimension and adjacent one edge thereof. A generally rigid reinforcing member is provided for each aperture thereby providing a requisite amount of reinforcement for the sheet member. A substantially J-shaped hook-like member is secured to the axially opposed upper surface portion of the sheet member for engagement with another member carrying a printing plate.
