Water-based inks are printing inks that use water as the primary solvent instead of petroleum-based solvents. They are commonly used in various applications, including flexographic printing, screen printing, and digital printing. These inks are known for their lower environmental impact, as they emit fewer volatile organic compounds (VOCs) compared to traditional inks. These inks are made from pigments or dyes suspended in a water-based solution, making them safer for both the environment and human health. They provide good adhesion to various substrates, such as paper and cardboard, and are often used for packaging materials. Additionally, water-based inks are easy to clean up with water, making them user-friendly.
