Shown here are enlarged characterizations of the recorded grooves starting with the master lacquer through full "process plating" to the final pressed record

M a s t e r  L a c q u e r

A music source is fed to a mastering lathe and the modulated signal causes the grooves to be cut in the master lacquer. The master lacquer, although slightly larger, appears very much like a finished LP without labels. The master lacquer is then put in electroplating, where the metal master is made (to eliminate groove deterioration).

From each master lacquer only one metal master can be plated, from which the metal mother is plated.

Metal mothers can be "pulled" from the one metal master from which metal stampers are plated.

Metal stampers (the manufacturing press discs) can be "pulled" from each metal mother and from each stamper approximately 500 to 1,000 finished records can be pressed.
