ABSTRACT:
A lightweight, thin walled, plural metal coated plastic sleeve for use in rotogravure or flexographic printing as well as a rotogravure printing cylinder are disclosed. The sleeve is supported internally and laterally by, for example, an expanding mandrel containing journal bearings and the resulting combination may be used as a rotogravure printing cylinder in a rotogravure printing machine. The sleeve and cylinder are lightweight and easy to handle and store and are adapted for quick changes in the printing machine without removal of the journals and the internal support. The particular method of making the sleeve enhances the adhesion of the copper to the plastic base.
