What are the traditional methods for gravure cylinder copper plating?

Traditional methods of gravure cylinder copper plating include:

1. Electrolytic Plating: This method involves submerging the cylinder in an electrolyte solution containing copper ions. An electric current is then passed through, causing copper to coat the cylinder's surface.
2. Manual Coating: Using brushes or pads, operators manually apply a copper solution to the gravure cylinder. This method is labor-intensive and requires skilled technicians.
3. Bath Plating: Cylinders are immersed in a bath of copper solution. The process can be time-consuming and typically leads to uneven coatings.
