What are printing inks?

Printing inks are colored liquids or pastes used in various printing processes to transfer images, text, or designs onto surfaces such as paper, fabric, plastic, or metal. They are composed of pigments or dyes, binders, solvents, and additives, each serving a specific purpose in achieving the desired print quality and durability. Different types of printing, such as offset, flexography, gravure, and digital printing, require specific ink formulations to ensure compatibility and optimal results. The choice of ink depends on factors like substrate, print method, and end-use requirements. Printing inks play a critical role in industries ranging from publishing and packaging to textiles and product labeling.
