The number of prints that can be made from acid or dry point etched copper plates can be substantially increased by electro-deposition of iron onto the surface of the plate. This process is traditionally, but incorrectly, known as steel facing. Using the Electroetch processor at 2 volts and with about 50 gm/l of aqueous sal ammoniac instead of at 6 volts with 225 gm/l gives excellent coating without the need for the operator having special skills.
