A gravure printing roller comprises a body or shell (15) moulded from syntactic compositions comprising microbeads of a plastic, glass or ceramic material in an e.g. polyurethane matrix. The shell (15) is machined to the required size and then a copper coating (17) is deposited on the machined surface, and chrome treated. An electrically conductive coating is first deposited on the machined surface which coating comprises a conductive agent such as finely divided metal.
