what is eco-friendly ink?
eco-friendly ink is a kind of ink made from soybeans, linseed (flax), tung (chinawood), castor, canola, and safflower. as opposed to traditional petroleum-based ink, soy-based ink is more environmentally friendly, might provide more accurate colors, and makes it easier to recycle paper.
why eco-friendly ink plays an important role in green printing?
eco-friendly ink may be the solution to the environmental health and safety concerns of the printing industry. a new study confirms that eco-friendly ink can help to reduce the environmental burden of the printing industry. soybean oil comes from a renewable source: soybeans. soybean agriculture uses only 0.5 percent of the total energy needed to produce eco-friendly ink.
eco-friendly ink is naturally low in vocs (volatile organic compounds, chemical compounds that evaporate and react to sunlight) and its usage can reduce emissions causing air pollution.
researchers at western michigan university have found that eco-friendly ink is removed more effectively from paper than traditional petroleum-based ink during de-inking, 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.
eco-friendly inks show a greater rub resistance and vibrant colors. soybean oil’s clarity allows pigments to reach their full potential, resulting in deep, rich bright colors. eco-friendly ink delivers a high quality print compare to traditional petroleum-based ink.
eco-friendly ink maintains its lithographic stability throughout the entire print job, so the press operator makes fewer adjustments during production and rejects fewer copies because of inferior quality.
