Processing plants

Some companies specialize in electroforming, processing metal plates from lacquers, only.

Lee Plating in California, USA, signed their metal plates with "L-" followed by five digits, with an added "-X" on side B [1]. They usually added the code to the lacquers before electroplating, because it appears deep and smooth in the matrix code. They went out of business around 2000 [1].
