Abstract
The present invention relates to a method for producing an electroforming mandrel. The method comprises providing a substrate which transmits actinic radiation with a pattern which masks the transmission of actinic radiation, depositing on a surface of the patterned substrate a continuous conductive film which transmits actinic radiation depositing on the conductive film a continuous layer of a photoresist, exposing said photoresist to actinic radiation through said masking substrate and conductive film, and developing said photoresist to selectively remove a portion thereof in order to uncover a pattern of the underlying conductive film.
