Water-based screen printing inks are a type of ink specifically formulated for screen printing applications. Unlike solvent-based inks, water-based inks use water as the main carrier instead of organic solvents. This makes them a more environmentally friendly and safer alternative, as they have lower VOC (volatile organic compound) emissions and reduced flammability.

Water-based screen printing inks are a popular choice for those seeking a more environmentally friendly and soft hand feel in their prints. They offer good color reproduction and versatility while being easier to clean up. However, they do have specific drying requirements and considerations when printing on certain fabrics. Overall, water-based inks are a preferred option for sustainable and high-quality screen printing applications.
