Soy oil based inks became very much popular several years ago when they were used as a replacement for petrochemicals oils, they are a popular crop grown by the farmers widely available in capacity. Soy based inks were used as a replacement for the petroleum oils. This issue has gained popularity as it addresses the various environmental issues and they have even reduced the dependence on petrochemical based inks, they have even reduced the dependence on the foreign based products. Other home based products which are used in the preparation of inks are cottonseed, vernonia, sunflower, tung, linseed and canola.

The printing inks used these days are used in different classes:

Sheet fed ink which is dried by the process of oxidation or polymerization Newspaper inks which are dried by the process of absorption and oxidation. Heat set inks which are dried by the different actions of heat.

The American Soybean association has remained very instrumental in the late 1980’s in promoting the usage of soy oils in the printing inks. They have also established the minimum percentages of the usage of the soy oils so as to use the soy seal which could be used on the printing base. The minimum levels of the printing inks have been displayed in the following ways like:

  • 30% of colored new inks

  • 20% of business forms inks

  • 40 %of black news inks

  • 20% for sheet fed inks

  • 7% for heat set inks

The heat set ink manufacturers these days are substituted by the soy oil today instead of the linseed oil. It is important to understand that the ink manufacturers these days are replacing one vegetable oil for another.
