Abstract
A printing sleeve for use in flexographic or gravure printing applications is provided. In particular, the printing sleeve contains a bridge layer that is formed from a generally rigid and relatively expandable material, which is disposed adjacent to a core layer. For example, in one embodiment, the bridge layer is made from a polyurethane material having a Shore D hardness of about 20 to about 85. As a result of the present invention, printing sleeves can be formed to be more durable and maintain better TIR tolerances than conventional printing sleeves.
