QUICK FACTS about Soy Inks*
Degradability studies concluded that the pigment carrier in 100-percent soy ink degrades almost twice as completely as ink made from soy oil and petroleum resins, and more than four times as completely as standard petroleum inks.
Soy ink is a helpful component in paper recycling because the soy ink can be removed more easily than regular ink from paper during the de-inking process. It has a number of environmental benefits. Much of the soybean crop requires no irrigation, limited fixed nutrients, and leaves fewer agricultural residues than other crops.
Soy ink also has low levels of VOCs, (volatile organic compounds) which helps to reduce air pollution by minimizing toxic emissions.
Some printers report that they need less ink to print the same amount of paper when compared to petroleum inks. Soy ink has been found to spread approximately 15% further, reducing ink use and printer cleanup costs.
Newspapers use soy ink regularly, especially for color because it creates a sharper and brighter image. Color newspaper inks are more competitive to petroleum-based inks as well. They are only about five to ten percent more because the price is more due to the cost of the pigment, which is not as big a factor with black inks.
Color soy inks are more widely accepted because they become the most quickly cost effective after savings in terms of excess pigment, VOC and printer cleanup costs. Soy inks also work well for label printing as they allow a reduction in ink coverage by 85% compared to water-based inks.
