Resins, colorants, solvents and additives are the main components that are used to formulate printing inks. Some of these chemicals contaminate the soil, water and environment when released into landfills, water streams and atmosphere. Some of these ingredients even create potential health hazards upon contact with the human body. These problems and particularly the rising price of petroleum are main reasons to look for new resources for making more environmentally friendly printing inks. Soybean protein and soybean oil are potential renewable raw materials for this replacement. Soy oil is already successfully implemented in lithographic printing processes, including litho inks for printing newspapers, books and magazines. Soy protein is also employed in flexo packaging. There is a lack of information about soy polymer use in digital inks. In this research, soyprotein was used as a resin for water-based inkjet inks formulation. Also, an acrylic water-based inkjet ink was formulated in order to compare with soy ink. Both of them were printed onto plain paper with a Dimatix inkjet printer. Properties of these inks were compared before and after printing. The soy-based inkjet ink showed better results in some of the tests.
