Gravure printing roll and method of manufacturing the same

A gravure printing roll, comprising:

• a hollow roll;
• a copper plating layer which is formed on a surface of the hollow roll and a surface of which has a large number of gravure cells;
• a metal layer formed on a surface of the copper plating layer,
• a metal carbide layer formed on a surface of the metal layer, the metal of the metal carbide being of the same metal as that of the metal layer;
• and
• a diamond-like carbon coating layer covering a surface of the metal carbide layer, wherein
• a depth of the gravure cell coated with the diamond-like carbon coating layer is 5 μm or more and less than 10 μm.

A method of manufacturing a gravure printing roll, comprising the steps of:

• preparing a hollow roll;
• forming a copper plating layer on a surface of the hollow roll;
• forming a large number of gravure cells on a surface of the copper plating layer;
• and
• forming a diamond-like carbon coating layer on the surface of the copper plating layer, wherein
• a depth of the gravure cell coated with the diamond-like carbon coating layer is 5 μm or more and less than 10 μm.
