Another embodiment relates to an apparatus for electroplating a rotogravure cylinder out of a plating solution. The apparatus includes a plating tank adapted to rotatably maintain the cylinder and to contain the plating solution so that the cylinder is at least partially disposed into the plating solution, and an anode system having at least one anode at least partially disposed within the plating solution. The anode includes a conductive core, a first layer including titanium securely applied to the conductive core and a second layer including at least one platinum-group metal or platinum-group metal oxide and at least one valve metal or valve metal oxide. The cylinder and anode system both connectable to a current source.
According to an exemplary embodiment, titanium tubes, which may include a protective surface material, are shrunk onto a lead or copper core material. As shown in FIG. 25, non-dissolvable anode 130 may take numerous forms, shapes, or proportions, including having a generally round cross-section (depicted in FIG. 25 a), a square cross-section (depicted in FIG. 25 b), a generally rectangular cross-section (depicted in FIG. 25 c), or of a wide variety of shapes, sizes, proportions, or combinations thereof. According to a preferred embodiment, the ends of core 134 are also protected by a protective surface material. According to one embodiment, shown in FIGS. 25 a-c, surface material 136 includes caps 140 attached to side portions 139 of protective surface material 136. Depending on the type or nature of the protective surface material used, other methods of protecting the ends of core 134 may be implemented.
