Abstract: A varnishing or printing plate includes a support layer, a varnish or ink transfer layer and a filling layer interposed between the support layer and the varnish or ink transfer layer. The filling layer comprises a plurality of sublayers connected together in succession so as to form the filling layer made of a polyurethane. Each of said sublayers of the filling layer has a thickness between 160 and 330 micron, and the polyurethane with which said sublayers of the filling layer are made is such that they have a Shore A hardness of between 55° and 65°.

Abstract: A pre-packaged cleaning system or kit is used for transport, storage and solvent impregnation of one or more fabric rolls used for cleaning components of printing machines. A container holds one or more fabric rolls, and one or more bags containing a solvent. When the rolls are to be used, the bags are perforated, allowing the solvent to flow onto the rolls. Thus, the rolls can be impregnated with solvent immediately before use. Because they are stored separately, the rolls and solvent are not likely to deteriorate even during long periods of storage.

Abstract: Support (10) for wrapping an absorbing material to be used into printing machine cleaning plants providing an exterior wrapping surface, characterized in that the interior surface (xx) of said support has anchoring elements (21) protruding with respect to said interior surface. The section of said anchoring elements has, through a perpendicular plane to the interior surface, at least one side forming an angle greater or equal to 90- with the interior surface.

Abstract: System for soaking absorbing material rolls or sheets (1b, 2b) with a solvent (1a, 2a), such a solvent being contained into a bag made of plastic divided into two separated partitions, one (A) suited to contain the solvent, and the other (B) to contain the sheets or rolls (1b, 2b) of absorbing material. Such a system is able to allow a contact between the solvent and the absorbing material only when one wants to use the absorbing material in order to clean the printing machines, after soaking it with solvent.
