Abstract
In a method of manufacturing a mould and providing it with a backing, the mould is derived from a parent information carrier by an electroforming process, after which electroforming process and prior to its separation from the parent information carrier the mould is provided with a backing. In order to reduce the cycle times and to improve the mechanical stability, the backing is formed by a UV-curable lacquer which is applied in liquid form and is distributed over the back of the mould, which is subsequently cured by exposure to ultraviolet light.
