Intaglio printing cylinder, comprising a core of a virtually undeformable material and a multilayer sleeve joined releasably thereto. The new intaglio printing cylinder especially is more durable than prior cylinders of a similar type, and it is interchangeable with conventional solid metal intaglio printing cylinders. The new intaglio printing cylinder is characterized by the fact that on the outside of the first, inner layer of the sleeve a plurality of ribs projecting outwardly and running substantially in the longitudinal direction of the cylinder are disposed. This intaglio printing cylinder has an improved stability, especially against circumferential shifting or displacement within the sleeve and thus is more durable. An additional improvement of its working characteristics is achieved by a continuous electrical continuity from the core to the outer copper layer. The new intaglio printing cylinder is especially suitable as a substitute for the solid metal printing cylinders still in use. It offers the advantage that, with a single core, a plurality of sleeves of different outside diameters can be used.
