Design Printing uses soy and other vegetable-based inks which are less harmful to the environment than their petroleum-based counterparts. Soy and vegetable products are used in ink for their oils, which act as the vehicle for the ink pigments. There are several types of vegetable-based printing inks, including linseed (Flax), tung (Chinawood), castor, canola, and safflower. Soy is popular because it is a very stable material that exhibits excellent wetting properties which enhance its ability to carry solid pigments. That low VOC inks can be produced from a wide variety of vegetable oils, not just soy, and we at Design Printing adhere to our standard of using the lowest VOC rated inks available.
