With the rise of environmental awareness and advancements in technology, UV flexo ink, as an emerging green printing material, is gradually becoming the new favorite in the printing industry. UV flexographic ink, with its unique advantages and wide range of application prospects, is leading a new round of revolution in printing technology.
UV flexographic ink, fully known as ultraviolet-curable flexographic printing ink, is a type of ink that utilizes reactive diluents to reduce the viscosity of the system. Its printing process involves applying the ink onto the substrate through a flexographic press, followed by rapid curing with ultraviolet (UV) light, achieving an efficient, energy-saving, solvent-free, and environmentally friendly green printing process. UV flexo ink combines the characteristics of flexographic printing, such as ink savings, fast printing speeds, and environmental friendliness, with the advantages of UV ink.
The main features of UV flexo ink include:
Rapid Curing Speed: Through UV exposure, UV flexo ink can cure rapidly within a short period, significantly enhancing production efficiency.
Excellent Abrasion and Chemical Resistance: The cured ink possesses outstanding abrasion and chemical resistance, enabling it to maintain the print's good condition in various harsh environments.
Superb Color Rendering: UV flexo ink offers vivid, stable colors that are resistant to fading, providing exceptional expressive power.
Environmentally Friendly and Non-polluting: Free from volatile organic compounds (VOCs) and solvent emissions, it is harmless to humans and the environment.
Wide Range of Applications: Applicable to various materials such as plastic films, metals, and papers, demonstrating broad versatility.
Based on their usage and characteristics, UV flexographic inks can be classified into several types, including:
UV Sheetfed Ink: Suitable for printing colorful and intricate products, featuring fast curing, minimal blurring, vivid colors, and glossy durability.
UV Plastic Ink: Applicable to printing surface-treated plastic films like PE, PVC, PET, BOPP, and synthetic papers, characterized by fast curing, strong adhesion, water resistance, and abrasion resistance.
UV Pearl Ink: Ideal for high-end packaging printing, imbuing products with a luxurious pearl or metallic sheen and robust adhesion.
UV Transparent Ink: Offering strong transparency and vibrant colors, suitable for printing vacuum-metallized aluminum, aluminum foil, and silver cardboard, achieving a hot-stamping-like effect.
UV Varnish: Including paper and polyolefin film UV varnishes, known for their fast curing, water resistance, abrasion resistance, and suitability for inline or standalone varnishing.
These various types of UV flexographic inks play crucial roles in packaging, label, advertising material, and optical disc printing, significantly enhancing the visual effects and functionality of printed products.
As a novel ink in modern printing, UV flexo ink, with its unique advantages and vast application prospects, is gradually transforming the traditional printing industry landscape. Although UV flexographic ink still faces minor issues requiring improvement, such as relatively high prices, it does not hinder its development prospects. StarColor's UV flexo ink, renowned for its strong weather resistance and high adhesion, has garnered praise from customers since its launch. We will continue to strive to provide customers with even higher-quality UV flexo inks.
