What Flexo printing inks are and how they support printing
Every package on a store shelf relies on a precise balance of materials and processes, but few elements influence print quality as directly as ink. In flexographic printing, ink is not just a colorant—it is a functional component that affects speed, consistency, and the final appearance of printed products. Understanding what these inks are and how they support printing helps explain why flexography is widely used across packaging and labeling applications. Understanding flexographic printing Flexographic printing, commonly known as flexo printing, is a rotary printing process that uses flexible relief plates. These plates transfer ink onto a wide range of substrates, including paper, plastic films, foil, and corrugated board. Because the process is fast and adaptable, it is especially suited for high-volume packaging production. In this system, inks must perform reliably under continuous, high-speed conditions. That requirement shapes how flexo inks are formulat...
