In order to improve the adhesion of water-based ink on substrate with low surface tension. Prepare ink samples of different dispersions with different kinds of dispersants and pigment/resin ratios and test their dispersion. Then prepare different ink samples with all kinds of film-forming resins and additives, measure the surface tension of the ink samples on the plastic which is used to characterize their wettability. Meanwhile use the IGT F1 printing eligibility instrument to make proofs with ink samples above. Discuss main factors that influence adhesion of water-based ink by analyzing wettability of ink samples. Research results indicate that: dispersion of water-based ink and resin have great influences on the adhesion on substrates with low surface tension; Right amount of adhesion promoter can effectively enhance the adhesion; The well wettability of ink on the substrates is the precondition to ensure adherence of the water-based ink.
