The role our kaolin plays in your ink formulation
Gloss & Sheen Control
Particle geometry fine-tunes gloss and matte finish across ink systems.
Viscosity Stability
Predictable rheology for smooth, consistent press-side performance.
Ink Holdout & Sharpness
Controlled absorption improves print definition and colour strength.
Low-Impurity Consistency
Batch-to-batch uniformity verified in our in-house QC lab.
Sree Sai InkFlow Extender Kaolin
Sree Sai InkFlow is a fine-particle kaolin engineered as an extender pigment for printing ink formulations. It enhances ink rheology, improves opacity, increases print sharpness and contributes to stable pigment dispersion across offset, gravure, flexographic and newsprint ink systems.
