Made using the highest grade materials, ALUSONG- Digital offers superb rigidity and impact resistance together with a smooth, flat surface. The superior Polyethylene core, specially developed paint system and unique easy-peel protective film combine with a 0.20mm alloy skin to provide a panel of outstanding quality. ALUSONG- Digital printing aluminum composite panel comes with an optimized lacquer system for direct-to-substrate digital printing showing excellent ink adhesion which allows advanced printing speed. The higher performance means higher output and lower costs.
Available in matte/matte or gloss/matte, both sides of the panel have a finish that has been developed specifically for digital and screen printing. This helps display colors with increased brightness and intensity with the added benefit of greater durability. The high quality film provides excellent protection and is designed to remove smoothly and easily, leaving no residue on the panel. Digital printing aluminum composite panels are especially useful for digital UV flat printing, which has the outstanding features of smooth glossy surface, high definition printing and good printing ink absorption.
