Properties of products with a variety of Waste frying oil (W) to Virgin oil (V) weight ratios (W:V ratios) were determined. We found that both viscosities and molecular weights of the obtained printing ink vehicles increased as the W:V ratios increased. Therefore, different types of eco-friendly printing inks for various printing applications can be produced. In addition, the cost and polymerization time of ink vehicle production could be reduced by using the waste frying oil.
