The present invention relates to a refurbished cylinder roller and a process for refurbishing cylinder rollers for use in printing machines. More particularly, the present invention also relates to a process for refurbishing metallic gravure cylinder rollers by replacing the worn outer plating layers with an extruded and thermally cured electrically conductive polymer material, and thereafter electroplating new outer plating layers thereon, the new plating layers including a new printing image formed therein. The present invention also relates to a refurbished gravure cylinder roller which includes a core member extending along an axial length, an image-carrying layer having a printing image formed therein and arranged circumferentially about the core member, and an electrically conductive intermediate polymer layer arranged between the core member and the image- carrying layer, where the intermediate polymer material has a conductivity selected to permit electroplating of the image-carrying layer directly thereon.
