Soy ink benefits
Soy ink and the environmentSoy ink may be the solution to the environmental health and safety concerns of the printing industry. A new study confirms that soy ink can help to reduce the environmental burden of the printing industry. Soybean oil comes from a renewable source: soybeans. Soybeans beans are widely available at low cost. Soybean agriculture uses only 0.5 percent of the total energy needed to produce soy ink. Almost half of all soybeans produced in America needs no irrigation. As soybeans are growing they temporarily remove damaging carbon dioxide, a greenhouse gas, from the atmosphere.
Soy 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 soy ink is removed more effectively from newsprint than petroleum 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. Residue waste ink is considered a liquid industrial waste that requires proper disposal. Many newspapers and large commercial printers are recycling their ink by mixing black ink with unused color inks. This process reduces waste and results in a more cost-effective, efficient use of ink.
Other benefits of soy inkSoy ink is available for newspapers, magazines, commercial printing, packaging, business forms and many other uses. Each form of printing requires a different type of ink and manufacturers have made various efforts to meet with the demands of customers. Soy inkt has following benefits:
- Vibrant colors - Soybean oil's clarity allows pigments to reach their full potential, resulting in deep, rich bright colors. In addition, used in newspaper ink, it shows an excellent outcome of pigments. Soy ink delivers a high quality print when you switch from petroleum-based ink to soy ink, and you may even see an improvement!
- Lower rub-off - Soy inks show a greater rub resistance. This is especially of important for newspaper readers.
- Soy ink is cost effective - The prices of soy ink colors are competitive with conventional ink colors since most of the cost in the colored inks comes from the pigments used and not the vehicle portion of the formulation. Because soy ink provides more intense color, printers may not use as much ink. As a result, more materials can be printed with less ink and thereby reducing their costs.
- Laser proof - This is important when ink needs to be exposed to the heat of a laser printer or copy machine. As the boiling point of soy ink is lower, there is less chance of the ink being transferred to the machine parts instead of the paper.
- Stability - Soy 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.
