How does spot UV coating work?

Spot UV coating is a printing technique that uses ultraviolet (UV) light to cure a liquid coating, creating a glossy or matte finish on specific areas of a printed piece.

Process:

1. Printing: The design is printed on the desired substrate using conventional printing methods.
2. Coating: A liquid UV-curable coating is applied to the printed areas where spot UV is desired.
3. UV Curing: The coating is exposed to high-intensity UV light, causing it to cross-link and harden.

Effects:

1. Glossy Finish: Spot UV creates a high-gloss, reflective finish that enhances the vibrancy of colors and adds depth to the design.
2. Matte Finish: A matte spot UV coating provides a velvety, non-reflective texture that adds a touch of sophistication and subtle contrast.
3. Raised Effect: When applied in thicker layers, spot UV can create a raised or embossed effect, adding dimension and tactile appeal.
4. Protection: Spot UV coating provides a protective layer against scratches, wear, and fading, extending the lifespan of the printed piece.
