Ink & Pigment
High-Brightness Minerals for Inks & Pigments
Overview
The ink and pigment industry uses ultra-fine mineral fillers to extend costly pigments, improve ink rheology, and control gloss and opacity in print applications. Raviraj Minerals supplies high-brightness, ultra-fine calcium carbonate and talc tailored to the demanding requirements of printing ink manufacturers.
Calcium Carbonate
Ultra-fine, high-brightness calcium carbonate is used in printing inks as an extender pigment and functional filler. It partially replaces costly titanium dioxide in white and tinted inks, reducing formulation cost while maintaining opacity and print quality.
Our ink-grade CaCO₃ is produced with tightly controlled particle size distribution to ensure smooth ink flow, good stone-roll grindability, and compatibility with both solvent-based and water-based ink systems.
- Extends TiO₂ and reduces pigment cost in white and pastel inks
- Improves ink opacity, hiding power, and print density
- Controlled particle size enables smooth flow and easy grindability
- Compatible with offset, flexographic, and gravure ink systems
- High brightness ensures clean, bright printed colors
Talc Powder
Talc is used in printing inks as a matting agent and functional extender. Its plate-like morphology scatters light effectively at low loading, making it a highly efficient matting agent in varnishes and matte inks used for premium packaging applications.
- Efficient matting agent in matte varnishes and overprint coatings
- Improves ink rub resistance and mar resistance in printed substrates
- Controls ink gloss without affecting color or transparency
- Improves rheological properties and prevents settling in ink formulations
