For consumers and brand owners alike, pigments are the most critical component of inks. They provide the color that catches your eye, which is the signature of a brand. Just think of Tide Orange and Coca-Cola Red.
Ink manufacturers are particularly sensitive when it comes to working with their pigment suppliers. Not only must pigments meet regulatory criteria, but they must also meet production standards.
Jonathan Graunke, VP of UV/EB technology and assistant director of R&D for INX International Ink Co., spoke about the regulatory requirements.
“As we continue to work with the UN Sustainable Development Goals, it’s important we have pigments that meet stringent regulatory thresholds,” said Graunke. “As an example, the certainty that non-intentionally added substances (NIAS) are no longer present is critical. The absence of PAAs, heavy metals, and even pigments designed without halogenated materials such as chlorine, are now high priority areas. Additionally, we need products that will pass recycling protocols, with an emphasis on how they react to recycling washes.
