Printing Method
・We use in-house UV-curable ink, suitable for outdoor use.
・Our ink is highly durable, tested for abrasion and water resistance with real materials.
Cerakote® Coating
We apply a special Cerakote® coating for superior protection against dirt and scratches, preserving your design.
Developed by NIC USA, Cerakote® is an exceptionally durable ceramic-based coating, trusted in military equipment and Harley-Davidson motorcycles.
It repels water, offers exceptional durability, and is easily cleaned with water.
Protective Film for Acrylic Plates
On acrylic plates, we apply a specialized protective film as an alternative to Cerakote®.
It protects against rain, wind, and scuffs. The dirt-resistant film makes maintenance effortless—simply wipe it down with water and mild detergent if needed.
Note: The protective film is an integral part of the product and should be kept intact upon arrival.
