UV Curable Overprinting Varnish

Printing industry has been constantly seeking for high-performance coatings that not only protect printed surfaces but also enhance their appearance. UV curable overprinting varnish (OPV) has emerged as an effective solution that offers outstanding benefits compared to traditional varnishes.

UV curable OPV is a type of coating that is cured by exposure to ultraviolet light, providing an instant and high-quality finish. The coating is applied on top of the ink layer to protect the printed surface from abrasion, scuffing, and fading, while also adding gloss, depth, and contrast.

Advantage 1: fast curing time

Unlike traditional varnishes that require several hours or days to dry, UV curable OPV cures within seconds, enabling printers to increase production speeds and reduce turnaround times. Moreover, since the curing is initiated by UV light, there is no need for solvents or heat, making it an environmentally-friendly and cost-effective solution.

Advantage 2: versatility

The coating can be customized to meet specific printing requirements, such as adhesion, flexibility, scratch resistance, or matte effect. UV curable OPV can be applied on various substrates, including paper, cardboard, plastic, and metal, making it suitable for a wide range of applications, such as labels, packaging, magazines, and books.

Advantage 3: superior durability and performance

UV curable OPV also offers superior durability and performance compared to traditional varnishes. The coating creates a hard and resistant layer that withstands harsh environments, chemicals, and physical stress. It also prevents ink from smudging or bleeding, improving the legibility and sharpness of the printed content.

Advantage 4: a safe and healthy solution

In addition, UV curable OPV is a safe and healthy solution for both printers and consumers. The coating emits low volatile organic compounds (VOCs) and odor, ensuring a pleasant and hygienic work environment. It also complies with various regulations and standards for food contact, toy safety, and environmental protection.

Overall, UV curable OPV is a high-performance solution that offers numerous benefits for the printing industry, including fast curing time, customization, versatility, durability, and sustainability.
