Abstract: In a coplanar-joined printing carrier of at least two sheet-like partial printing carriers, wherein one of the partial printing carriers has a paper layer, the invention provides that the paper layer of the one partial printing carrier is weakened in its thickness along a marginal strip by removal of a partial layer, the other partial printing carrier has less thickness along one marginal strip than elsewhere, and the two partial printing carriers are joined together along their two marginal strips. Also described are a method especially suited to the making of such a printing carrier.
