Crack pattern is useful because it increases the lubricity by retaining some ink. Plating time minimal. Hanging the cylinder in the center of an anode ring upon which are hung straight anodes. Most widely used method for larger cylinders. High current density more cracks.
Excessive speed can decrease plating efficiency.
Not to burn the surface. Burn - frosty appearance. Cylinder must be pre- warmed. Spraying hot water onto cylinder in the degreasing tank before plating. Polyvinylchloride, polypropylene are applied over steel.
