SOY Inks – Good For The Printing Industry, Good For The Environment
Research has found that soy ink is removed more effectively from paper than petroleum ink during de-inking process in recycling, resulting in less paper fiber damage and a brighter paper. In addition, the waste is not considered hazardous and can be treated more easily, completely and cost-effectively. Residue waste ink is considered a liquid industrial waste that requires proper disposal.
Highly recyclable – When recycling paper, any printed ink has to be removed first. Paper printed with soy-based ink has a faster rate of dirt removal during the de-inking process, which makes it easy to recycle. Additionally, soy ink is more than four times more biodegradable than standard ink, so even paper that isn’t recycled with have less environmental impact.
Sustainability – Naturally, soy ink is made from soybeans, a renewable resource (unlike standard petroleum). What’s more, it’s actually made from a byproduct of soybean farming. This means that no new crops need to be harvested to create soy-based ink. Also, soybeans require very little irrigation and only a small amount of energy to cultivate.
Soybean oil’s clarity allows pigments to reach their full potential, resulting in deep, rich bright colors. Soy ink delivers a high quality print with lower rub-off and greater rub resistance. When you use a product with soy ink in a copy machine, once the ink is exposed to the heat, the boiling point of soy ink is lower, so there is less chance of the ink being transferred to the machine parts instead of the paper.
Soy inks offer better stability and higher quality it maintains its lithographic stability throughout the entire print run, so press operators make less color adjustments during production thus rejecting fewer copies. This results in less paper waste, and higher overall print quality.
