ABSTRACT:
A new printing surface is produced from an etched printing surface after previous printing use by applying insulative material into the etched wells of the printing surface, deplating metal from the printing surface while simultaneously scrubbing the excess insulative material even with the deplating surface, further deplating below the level of etching until a smooth surface is produced, and then replating metal back on to the desired thickness.
