ABSTRACT:
A print element for use in high speed printing machines, having a plurality of metallic print characters which are substantially flat and are flexible. The characters are struck by a hammer surface which is curved so as to conform to the curvature of the platen upon which the characters strike. The characters are struck by the curved hammer surface and thereby temporarily deformed to conform to the curvature of the platen, thus producing a character of uniform density on the printing surface.
