ABSTRACT:
A wrap-on printing plate with first and second clamping bars along opposite sides thereof for installation on a printing cylinder is produced by providing a layer defining a printing plate body, forming from marginal portions of that layer, along opposite sides thereof, first and second foundations for the first and second clamping bars, respectively. These clamping bars are provided on such first and second foundations by interatomic bonding between the first and second foundations and the first and second clamping bars, respectively. To this end, the layer may, for instance, be electroplated on existing clamping bars in a special form, or, as presently preferred, material from which the first and second clamping bars are formed may be electroplated on the first and second foundations formed in marginal portions of the mentioned layer.
