UV printing works basically by shining an ultraviolet LED light source right after the ink is applied. The UV dries out the ink instantly, resulting in fine art and sharp print quality because the ink doesn't spread due to rapid drying time.
Additionally, UV dried ink is far more durable than regular ink and provides higher levels of weather-resistant heat resistance, and it doesn't fade or absorb into the atmosphere.
But the main advantage of UV printing is its property to stick to nontraditional surfaces as long as the UV light source stays within a specific range of the material's surface. It can print on just about any material, including but not limited to acrylic, aluminum, wood, glass, stainless steel, and plastics.
UV LED technology was developed as a way to dry nail polish during a manicure instantly and has rapidly become one of the most versatile and valuable technologies in a lot of industries – including medicine, rapid prototyping, and low scale manufacturing.
