What is soy ink?

Petroleum is an important material for producing traditional inks. At the end of the 1970s, the shortage of petroleum led to a sharp increase in its price. The “Newspaper Association of America” realized that we needed more reliable printing raw materials. After testing more than 2,000 kinds of vegetable oils, it finally chose soybean oil, which has the most stable effect, to replace petroleum. Compared with petroleum inks, soybean oil inks can reduce the generation of volatile chemical substances and also solve the environmental health and safety problems in the printing industry. The American Association has also made specific regulations on the content of soybean oil in inks:

Heat-set rotary printing inks must contain at least 10% soy oil.
Sheet-fed offset inks must contain at least 20% soy oil.
Foaming inks must contain at least 40% soy oil.
Newsprint inks must contain a minimum of 55% soy oil.

What are the characteristics of soy ink?

Bright and pure colors	Soy ink provides high saturation and bright colors, and also has excellent gloss and high concentration.
Superior printing performance	It has strong transferability, good water resistance, excellent wear resistance, and a stable printing process.
Safe and reliable:	The packaging is safe, non-flammable, non-explosive, non-corrosive, meets the usage standards, and ensures safer use.

What are the advantages of soy ink?

Bright colors and high saturation: Compared with traditional inks, the images printed with soy ink are clearer and brighter. Its high transparency and bright colors are especially suitable for large-area color packaging printing.
How about its environmental protection performance? The content of volatile organic compounds in soy ink is as low as 0.8%, far lower than 4.6% of petroleum-based inks. Soybeans have a short growth cycle and can be naturally degraded, imposing minimal burden on the environment.
Easy to recycle: Soy ink is easier to deink than ordinary inks and causes the least damage to paper fibers. The waste soy ink residues can also be naturally degraded, which is beneficial to sewage treatment.

What are the applications of soy ink?

Due to its stability and environmental protection characteristics, soy ink is increasingly widely used in the packaging field. With the enhancement of consumers’ environmental awareness, soy ink has been widely used in the packaging of various environmentally friendly products such as food boxes, luxury goods packaging, and cosmetics packaging, and has become an ideal choice for brands to pursue sustainable development.
