Electrolytic Photoetching
Summer 1982
In the Eastman Kodak literature of the 1960s many references
are made to electrolytic photoetching
as an alternative process to the more conventional
methods of PCM, such as immersion and spray-etching.
The electrolytic method requires the imaged workpiece
to be connected as an anode in a cell comprising an
electrical power unit, aqueous electrolyte and inert
cathode.
