Solvent ink is a type of ink that uses a solvent as its primary carrier. It is commonly used in large-format printing for outdoor signage, banners, and vehicle wraps due to its durability and resistance to water and UV light. The solvent helps the ink adhere well to various surfaces, including vinyl and canvas. This ink is available in both eco-solvent and traditional formulations. Eco-solvent ink is less harmful to the environment and has lower levels of volatile organic compounds (VOCs), making it a safer choice for indoor applications. Overall, solvent ink is valued for its vibrant colors and long-lasting results.
