Abstract
Abstract A composite of several materials constructed to form a printing disc, of the type used in high speed printers. The printing disc is manufactured in separate stages in order to achieve characteristics within the final assembly that are necessary for high speed quality printing. The assembled printing disc comprises a disc shaped member of flexible plastic. The hub of the disc has radially extending arms which each unite with a print head character composed of a thin layer of powdered metal or plastic zinc plated with a layer of metal.
