AquaMax ENVELOPE Black water base flexo ink is formulated for uncoated paper and envelope stocks run on 150-600 LPI (9.0-2.3 BCMs) anilox roller-equipped presses. AquaMax ENVELOPE Black is not recommended for non absorbent substrates and plastic films. AquaMax ENVELOPE Black has low viscosity (<1.2 poises or 16 seconds #3 Zahn Cup) so it dives into the uncoated paper substrate quickly for excellent drying speed and easy handling and die cutting. All AquaMax aqueous flexo inks, AquaMax ENVELOPE Black contains a very forgiving amine neutralizing system for longer runs between pH adjustments. 

Like many other Kerley Ink products, AquaMax ENVELOPE Black can be fine-tuned in strength and viscosity for your press on a special basis… Have it your way!
