Printing plate for linear bar symbol code

摘要

A printing plate for printing a linear bar symbol code includes a body portion which is adhesively bonded to a mylar mounting sheet that is secured to a typical printing cylinder core. Integral with the body portion of the printing plate is a substantially rectangular frame member having opposed side members and end members which enclose a central channel. Disposed within the channel and integral with and connecting the opposed side members are a plurality of spaced bar members which define the linear bars of a symbol code. One of the side members includes a plurality of recesses having the configuration of numbers disposed in relief. The machine-readable linear bars correspond to the human-readable numbers of a symbol code. The frame member which constitutes a majority of the printing contact surface of the plate is raised the same distance from the body portion as the linear bar members such that the contact surface of the frame is flush with the contact surfaces of the bar members. By this arrangement, the frame member minimizes distortion of the linear bars when contact pressure is applied during a printing operation.
