Core Performance Features
1. Low oil absorption restrains ink viscosity growth, optimized for high-gloss offset printing formulas.
2. Smooth ink film surface with low haze under light printing coverage, even hiding power distribution.
3. Moderate oxidation reaches fine fineness via standard triple-roll mill, reduces surface pits and coarse particles.
4. Neutral-blue tone reproduces clear printing dots, presents natural layered effect for magazine and packaging print.
5. Low heat generation during high-speed rotary printing, reduces bubble and ink stacking failure rate.
Main Application
Heat-set rotary offset ink, coated paper high-gloss packaging ink, low-viscosity flexo liquid ink, leather & non-woven textile base tint, special coated paper Secondary Reminder: Limited adaptability for high-solid thick coating; cannot replace reinforcement carbon black for rubber production.
