Water-based inks and oil-based inks are two different types of inks that are used for various purposes.
Water-based inks are made by mixing colourants with water as a solvent. They are primarily used for printing on paper and other porous surfaces. They are more environmentally friendly than oil-based inks because they do not contain volatile organic compounds (VOCs), which can be harmful to the environment and human health. Water-based inks are also easier to clean up with soap and water.
Oil-based inks, on the other hand, are made by mixing colourants with an oil-based solvent, such as linseed oil or mineral spirits. They are primarily used for printing on non-porous surfaces, such as metal, plastic, and glass. Oil-based inks are more durable and long-lasting than water-based inks and are resistant to fading and water damage. However, they require more time to dry, are more difficult to clean up and contain harmful VOCs.
