Why Should We Choose Soybean Ink for Printing?
Published on Jun. 04, 2020
Soybean oil is an edible oil, which can be completely integrated into the natural environment after decomposition. Among vegetable oil inks of various formulas, Soy Based Offset Ink is a truly applicable environmentally friendly ink. Moreover, its output is abundant, the price is cheap (especially in the United States), the performance is safe and reliable, the printing effect is good, and it meets the standards of printing inks, and it is excellent in environmental protection. Compared with traditional ink, soybean ink has bright color, high concentration, good gloss, better water adaptability and stability, friction resistance, dry resistance, and other properties. Characteristics and advantages of soybean ink:
1. Excellent environmental protection. Eco Friendly Quick Dry Soy Ink is free of VOCs. VOCs are volatile organic compounds contained in petroleum and contain aromatic polycyclic hydrocarbons. It is one of the strong carcinogens. Ink manufacturing, During printing, drying process or equipment cleaning and waste ink treatment, a large number of organic components are volatilized, which not only seriously harms the health of production operators, but also causes great damage to the environment. At present, the volatilization of VOC in printing inks has become an environmental pollution One of the important pollution sources. When manufacturing ink, printing drying, or cleaning manufacturing equipment and printing facilities, if soybean ink is used, VOC emissions will be reduced, which is beneficial to the environment and health.
2. Resistance to friction and heat. According to the American Press Association, under normal circumstances, newspaper readers often have their hands stained with ink when reading. This is because the ink on the substrate is easily rubbed off after printing with traditional ink. Soy ink is more resistant to rubbing than traditional inks so that newspaper readers are not bothered by black hands, and at the same time, there is no unpleasant odor. The boiling point of soybean ink is much higher than that of petroleum volatile components. When the oil is heated by laser printers or copiers, it will not volatilize and stick to the paper, nor will it pollute machine parts.
3. It is easy to remove ink from waste paper. According to the research, it is found that for the deinking of recycled waste paper, soybean ink is easier to drink than ordinary offset printing ink, and the paper fiber damage is less. Generally, more than 80% of newspaper paper uses recycled paper. Using this feature of soybean ink, there is little waste when recycling waste paper, and the recycling cost is low, which is extremely competitive in the industry. The waste soybean ink residue after deinking treatment is relatively easy to degrade, which is conducive to sewage treatment and controls the quality of discharged water. Research at Western Michigan University, known for its papermaking technology in the United States, confirmed this characteristic. This characteristic of soybean ink is a very favorable factor for waste paper recycling (recycled paper) operations.
4. Good color. The raw material of soybean ink is salad oil and other edible oils, jointly developed by Japan Elite Church Printing Company and Toyo Ink Company. Salad oil as refined vegetable oil is processed through a series of strict decolorization, deodorization, free fatty acid removal, and other refining processes. Its fluidity and coloring are excellent, and it has high transparency, bright colors, and is not easy to fade. It is suitable for a wide range of color printing. The UV-mixed soybean ink for waterless printing has excellent deinking performance and no problem in recycling; it can print high-quality prints without powder spraying, and can also obtain excellent prints in post-processing such as film sticking and printing coating, Improve the operating environment.
5. Good inking property. Compared with cured inks or waterless offset printing inks, soybean oil inks dry more slowly. However, from the practical results, the transferability of the ink is good, the inking property of the solid part is good, and the dot color of the bright tone part is uniform. After the ordinary offset ink reaches the paper, the solvent penetrates quickly, and the ink film will break off in the part near the paper surface, while the soybean oil ink penetrates slowly, and the peeling surface of the ink is closer to the side of the blanket, which is equivalent to The thicker ink film is transferred to the paper surface, so the amount of ink transfer increases.
6. Good laser resistance. When printed materials require laser resistance, soy ink is a good choice. Its boiling point is much higher than the volatile components of petroleum. When the ink is heated by a laser printer or copier, it will not volatilize and stick to the paper, nor will it pollute the parts of the printer.
7. Renewable. Vegetable ink is not a non-renewable resource like petroleum-based ink. For example, soybean oil contained in soybean ink is a sustainable and biodegradable rich resource. It can continuously provide raw materials for ink production and has good environmental protection. The use of vegetable oils (such as soybean oil) to replace some petroleum-based mineral oils to make inks can promote the industrial use of vegetable oils in various countries, expand the application range of vegetable oils, and at the same time reduce the consumption and import of non-renewable oil and save foreign exchange.

8. Low comprehensive printing cost. The study found that vegetable inks are easier to deink than traditional inks, and they have less damage to paper fibers, and the quality of the recycled paper is better. Using this feature of plant inks, waste paper recycling has fewer waste materials and lower recovery costs; the waste plant ink residues after deinking treatment are easier to degrade, which is conducive to sewage treatment and controls the quality of discharged water. Heatset soy based printing ink has a wide range of colors, rich and bright colors, and a small amount of ink can show the effect that a large amount of traditional ink can show. In addition, because the traditional ink contains organic compounds, in order to avoid causing environmental pollution, its disposal has become a problem that plagues ink manufacturers and printing plants. However, soybean ink can be backfilled and mixed in new ink, which is not only beneficial to environmental protection but also reduces production costs.
9. Conducive to energy security. The oil that traditional inks rely on is a non-renewable resource. With a large amount of use, it is increasingly depleted. The energy crisis has become the first problem facing mankind. Many industries have turned their attention to renewable plant resources, such as biodiesel. The soybean oil in vegetable inks is natural, can be infinitely regenerated, and can be biodegraded. It has unparalleled advantages from traditional inks in terms of resource utilization and environmental protection.
