Water-based ink is a type of ink that uses water as its primary solvent. This makes it a more environmentally friendly option compared to solvent-based inks, which contain harmful chemicals. Water-based inks are commonly used in printing processes, such as screen printing and flexography, due to their lower levels of volatile organic compounds (VOCs). These inks are known for their vibrant colors and good adhesion to various surfaces, including paper and cardboard. However, they may not be as durable as solvent-based inks when exposed to moisture or extreme conditions. Overall, water-based inks are a popular choice for eco-conscious printing applications.
