3. Choosing the Plaque Finishing

 

Plating and/or Patina (Only for Metallic Plaques)

Electroplating is a process whereby a very thin layer of a metal is transferred chemically to cover the surface of another metal. For example a gold-plated plaque has a very fine coat (only a few microns) of 24K gold. Because gold resists oxidization gold-plating will also protect your plaque. Adding metal plating such as silver or gold makes your plaque look more valuable and attractive. You may choose among the following plating options: None, Nickel, Silver or Gold.

Patina

Patina is a procedure used to discolor a metal by oxidation. For example Antique patina is used to artificially "age" a silver-plated or silver plaque. Antiquating plaques prevents tarnishing.
Patina Options:

  • None
  • Bronze (only if your plaque is made of brass and has no plating)
  • Antique (only if you plaque is made of silver or silver-plated)

Applying Epoxy

Although all our plaques are lacquered by default, epoxy (a thick, hard and clear layer) can also be applied on the surface of a plaque to further protect its finish from humidity and oxidization. This feature is usually ordered for plaques having thermal impression designs.
