ABSTRACT:
A flexographic printing plate (80) having register marks (82) thereon is supported on the surface (16) of a support table (15) which is capable of being rotated about a central vertical axis. The register marks are viewed by an optical viewer television camera (84) and displayed on a video screen (28) on which are also projected sight marks (86, 87). The operator adjusts the rotational position of the table until the register marks on the plate align with the sight marks. The plate is then punched using a punch unit (24) to form a series of holes (89) in the plate (80) which defines a line either parallel or perpendicular to the axis of the images (81) on the plate. The punched plate is then laid on the top surface of a mounting table (91) of a mounting unit (90) and pins (93) are inserted through the holes in the plate into holes (92) in the table surface. A portion of the plate is adhered to the surface of the plate cylinder, the pins (93) are removed, and the arbor (96) is rotated to draw the plate off of the mounting surface onto the plate cylinder while a pressure roller (145) presses against the plate on the mounting table to prevent it from changing its orientation as it is drawn onto the plate cylinder surface.
