Conventional printing inks are petroleum-based and because of their ingredients, have a relatively high environmental impact. They contain pigments and oils which need to be extracted from the earth, and alcohol-based solvents that emit Volatile Organic Compounds (VOCs) into the air, which cause environmental and ozone pollution and are harmful to health.
What are Vegetable oil based inks?
Vegetable oil inks are derived from soy, palm and other non-edible vegetable oils. They are environmentally friendly and the sustainable alternative to traditional petroleum based printing inks. By 2010 more than 70% of the printing inks in Japan were soy oil based inks. In 2011, the Japan Printing Ink Makers Association introduced vegetable oil inks as an environmentally friendlier printing ink.
Vegetable oils are considered a more viable, sustainable raw material for ink production than soy oil. Vegetable oil based inks are derived from renewable soybean oil, linseed oil, tung oil, palm oil and palm tree oil. Printers are discovering that vegetable oil based inks often produce more vibrant colours than traditional inks and require less pigment to create the same effects.
