UV printing is a digital printing method that uses UV light to cure or dry inks, coatings, adhesives, aluminum, foam or acrylic. With UV printing, you can print on a variety of materials. This drying photochemical process was originally introduced as a way to dry gel nail polishes. The printing industry has since embraced this process because it makes it easier to print on almost anything, including beer bottles, brochures and signs. UV printing is the same as conventional printing. However, there are differences in the type of ink used, the drying process, and the types of products that can be printed.
