The roller (1) for working with a fluid film, e.g. the blanket roller in an offset printing press to transfer ink, comprises an inner core (3) and a roller cladding (2) with a given thickness (d). The cladding has two layers with different hardnesses, with a generally continuous hardness gradient over at least part of the cladding thickness. <??>The roller (1) for working with a fluid film, e.g. the blanket roller in an offset printing press to transfer ink, comprises an inner core (3) and a roller cladding (2) with a given thickness (d). The cladding has two layers with different hardnesses, with a generally continuous hardness gradient over at least part of the cladding thickness. The hardness levels are set by one or more components using a hardener, cross linking agent, activator, photo-initiator, monomers and oligomers or a softener. |
