Printing inks require precise viscosity control to avoid bleeding, uneven coverage, and nozzle clogging. Qinghong’s 801-A/801-B organic bentonite adjusts ink rheological properties, enabling shear-thinning behavior that ensures smooth flow during printing . It disperses pigment particles (50-200nm) uniformly, enhancing color saturation and print definition . Suitable for offset, gravure, and screen printing inks, this solution reduces dot gain by 10% and improves drying speed. The odorless, non-toxic formulation meets global printing safety standards, making it ideal for food packaging and decorative printing applications.
