Ink dispersion is a core step that determines printing quality. In real production, pigments tend to agglomerate, dispersion stability is poor, color consistency is uneven, and gloss is insufficient, which can cause color deviation, poor leveling, or clogged plates in printed products—directly affecting production efficiency and product value.
Chemi Tech focuses on ink dispersant R&D and proposes scientific solutions for these industry pain points. Through molecular structure design and application testing, we have launched a series of highly effective dispersants. Their working mechanisms include: anchoring groups that adsorb onto pigment surfaces, and solvation chains that form a steric barrier to reduce particle re-agglomeration; lowering the surface tension of the system to promote wetting and dispersion; and enhancing tinting strength and color saturation.
The solution is delivered in four concrete steps. First, analyze the ink system and pigment type to match the appropriate dispersant model. Second, use a suggested dosage of 0.5% to 3%, optimized through experiments. Third, adopt a high-speed shear process to ensure uniform dispersion. Fourth, verify through stability testing and print-suitability evaluation.
After using our dispersant, one printing enterprise shortened its ink grinding time by 20%, reduced the pigment settling rate by 60%, and kept the printed color difference within a Delta E value of 0.8, with significantly improved batch-to-batch consistency.
With technical service at its core, Chemi Tech provides customized solutions to help customers improve ink performance and market competitiveness.
