UV coating, also known as UV varnish, is a transparent coating that is applied to the surface of printed materials, such as metallic paper, aluminium foil and plastic sheets.
- Provides a glossy, polished finish that enhances the appearance of printed materials
- Hardens the surface of printed materials, making them resistant to scratches and scuffs
- Offers excellent adhesion, ensuring that it adheres strongly to the substrate and does not peel or flake off easily
- Provides a high level of glossiness, smoothness, and leveling
- Feels great to the touch, with a smooth and polished surface
After being sprayed or rolled onto the substrate, it is cured by exposure to UV light, transforming it from a liquid to a solid and resulting in a hardened surface that is resistant to scratches and scuffs. The result is a glossy, polished finish that enhances the appearance and durability of printed materials.
UV coating offers several powerful benefits that set it apart from other types of coatings. Firstly, it has excellent adhesion, meaning that it adheres strongly to the substrate and does not peel or flake off easily. In fact, when tested with 3M tape, UV coating did not peel or flake off even after being pulled three times in the same spot.
Secondly, UV coating provides a high level of glossiness, smoothness, and leveling. By using high-quality additives, UV coating can achieve a mirror-like finish on good UV machines, with high gloss levels of 85 degrees or more. The result is a smooth and polished surface that not only looks great but also feels great to the touch.
Lastly, UV coating cures quickly. With sufficient energy from the UV machine, UV coating can achieve an efficiency of over 8,000 sheets per hour. This saves a significant amount of time in the production process, making it a highly efficient choice for businesses looking to improve their productivity.
UV coating is an excellent choice for enhancing the appearance and durability of printed materials. With its excellent adhesion, high glossiness, smoothness, and quick curing time, UV coating can provide a polished finish that not only looks great but also provides long-lasting protection against scratches and scuffs. Whether you are printing brochures, business cards, packaging materials, or any other type of printed material, UV coating is an excellent choice for enhancing their quality and appeal.
