Additives for Printing Inks
Raj Speciality Additives offers speciality additives for printing inks, pigment dispersions, colorants and ink formulation systems. Our solutions help improve pigment wetting, dispersion stability, foam control, flow, rheology, color strength, gloss and processing consistency.
Speciality additives for stable and high-performance printing ink systems
Printing inks require stable pigment dispersion, strong color development, controlled viscosity, good flow, foam control and consistent print performance. Additives help ink manufacturers improve processing, storage stability and final application quality.
RSA supports ink and coating formulators with additive categories that help solve common ink formulation problems such as poor pigment dispersion, high viscosity, foam, poor gloss, color instability, settling, flocculation, poor flow and inconsistent print appearance.
Key benefits of RSA additives
- Improved pigment wetting and dispersion stability
- Better color strength, gloss and shade consistency
- Improved foam control during ink processing
- Better flow and application consistency
- Improved viscosity and rheology control
- Support for pigment concentrates and difficult pigment systems
Challenges in printing ink formulations
Ink systems require fine pigment dispersion, stable viscosity and consistent flow. Additives help improve ink processing, storage and print quality.
Poor Pigment Dispersion
Poor wetting and dispersion can reduce color strength, gloss, transparency and shade consistency.
Difficult Pigments
Carbon black, organic pigments and high-performance pigments often need stronger stabilization support.
Foam During Processing
Foam can occur during grinding, mixing, transfer and application, affecting processing and final ink quality.
Viscosity Instability
Incorrect rheology balance can cause poor flow, poor transfer, settling or inconsistent application performance.
Flocculation & Settling
Pigment instability can cause re-agglomeration, settling, shade variation and poor long-term stability.
Poor Gloss or Color Strength
Weak dispersion and unstable pigment systems can reduce final gloss, color intensity and visual performance.

How to choose additives for printing inks
The right additive depends on pigment type, ink chemistry, resin system, solvent or water phase, printing process, viscosity target and final performance requirement.
- For low color strength, evaluate wetting and dispersing additives.
- For difficult pigments, evaluate hyperdispersant support.
- For foam during grinding or processing, use compatible antifoam or defoamer additives.
- For poor flow or transfer, evaluate suitable flow additives.
- For viscosity drift or settling, use rheology additives where required.
- For pigment concentrates, check let-down compatibility and long-term stability.
