UV Coating Facts:

• Ultraviolet (UV) cure coating is basically a liquid compound when applied over ink to paper and exposed to the correct level of ultraviolet light, becomes instantly solid.
• UV coating does not have any VOCs, so the concern about the inhalation of vapors does not exist. In addition, there are no environmental concerns about hazardous air pollutants because the amount of ozone, produced by the UV lamps due to interaction of UV light and oxygen, is small enough and does not present any issue.
• UV coatings are protective and durable material with high levels of gloss, used in magazines, automotive brochures, annual reports, direct mail and promotional inserts. It is an ideal solution to give magazine covers a shinier, durable, high quality appearance which makes it stand out from the rest.
• UV coating “ adds value to the printed products by making them unique and more eye-catching.“Finishes can range from a flat mat appearance to high-gloss”.
• UV coating can be applied as a flood over an entire web width, or in spots to highlight specific areas.
• UV coating technology is one of the fastest-growing segments in the Graphics Arts industry.  In recent years, great technological advances was made in UV equipment and UV inks and coating has led to the safe and widespread acceptance of use of UV curable inks and coating. Today, many printers utilizing UV Curable Coatings on a regular basis to enhance the gloss levels, quality and productivity in both the pressroom and at trade finishing houses.

Performance Advantages of UV Coating:

• Superior Gloss & fast Curing Speed
• Low Energy Costs
• Environmentally Friendly "Zero VOC (Volatile Organic Compounds) Technology "- 100% Solids
