Traditional ink is dependent on the oil is a non renewable resources, with the use of a large number of and increasingly exhausted, energy crisis has become mankind faces first big problem, many industries have attention to renewable plant resources, such as biodiesel. The soybean oil and other plant ink from natural, can be infinitely renewable, and can be biodegradable, regardless of the use of resources or from the perspective of environmental protection with traditional ink unparalleled advantage. ... 

Definition of soybean ink: 

Oil (Soybean Ink) refers to the use of soybean oil instead of the traditional oil solvent ink. Soybean oil is an edible oil, which can be fully integrated into the natural environment, and in various kinds of vegetable oil ink, soybean oil ink is the real meaning of environmentally friendly ink. And the soybean production is rich, the price is low, the performance is safe and reliable. Compared with traditional ink, soybean ink has the characteristics of bright color, high concentration, good gloss, good water adaptability and stability, friction resistance, resistance to dry and so on. 

Origin of soybean ink: 

By end of 1970s, oil prices have soared, and the American Press Association is aware of the need for more reliable printing materials. As a result, the association of research and development department to try more than 2000 kinds of vegetable oil program, the final determination of the soybean oil this alternative ink solvent. 

In 1987, an Iowa media began with soy based inks for printing; in 2004, soy ink become major American daily printing oil, in order to promote soy ink R & D and the use of, the United States in 1993 has also set up a "national soy ink information center"; in 2005, soy ink in the United States and around the world promotion success. 

Advantages and disadvantages of soybean ink: 

advantage 

First is environmental protection. Soybean oil is a mild purification of soybean oil, mixed with pigment, resin and other additives. Replacing oil with vegetable oil, reducing the use of fossil raw materials, ease the tension of the earth's resources. And soybean ink is less volatile organic substances than the oil ink, reducing air pollution. Its degradation rate is 4 times as much as that of standard gasoline. 

Followed by the economy. Soybean ink is more pure than oil extracts, to achieve the same dyeing effect, the former requires less pigment, but also reduce the cost of ink. Illinois energy and Resources Department of hazardous waste research and information center in the 90s of the 20th century made a research on soy inks, many business printing report: "soy ink can 15% higher than the general ink ductility, to further reduce the amount of ink and printing cost thereby reducing." Although the average price of soybean ink than gasoline ink on average higher than 5%~10%, but in the use of pigment, volatile organic compounds and printer costs and other expenses, the former will spend less. 

There are many advantages: soy ink rub resistant is not black, no stimulus odor, light resistant and heat resistant, easy recovery, color etc.. 

shortcoming 

Of course, soybean ink also has shortcomings. For example, it is not suitable for personal printers. Because there are no volatile organic compounds in the presence of soy ink than the general gasoline ink dry, this is a challenge for some printing projects, such as paper is different from the newspaper's magazine. There is a problem, soybean ink depends on a single crop, once the threat of disease and insect pests, raw materials supply will become a problem. 

Main use: 

Soybean ink is widely used in the printing of children's books, the new non woven bag printed on, more able to reflect the environmental value of soybean ink.
