Abstract
In a printing press and attached onto the transfer cylinders, an anti-marking system that uniformly supports the transport and the release of the wet printed sheet from one station to the next. The anti-marking sheet consists of a two plus layer system, the outer layer being a textured surface and the inner layer being a microcellular material that is both compressible and resilient. The outer textured layer may be treated with either conductive/anti-static layers or an ink repellent layer or both. The two plus layer system is easily attached to both transfer cylinders and tracking/skeleton wheels using any combination of fixtures from Velcro™, magnetic, metallic, and pressure sensitive double sided tape to elastic loops.
