Carbon Ink
Gum arabic and lampblack or soot, were the common substance used for creation of Carbon ink. Gum Arabic was able to keep the particles of carbon in suspension and then adhere to the paper. When it is seen in sunlight or bleached, the particles of carbon do not fade for a long period. The use of carbon ink doesn’t damage the paper. This ink gives benefits of chemical stability and will not give any threat on the paper strength. However, this type of ink is not the right choice for permanence and preservation. Carbon ink tends to smudge in a humid surrounding and can be washed off. The best technique to preserve documents from carbon ink is to have them stored in a dry surrounding.


The recent research has created carbon ink made of carbon nanotubes successfully। They suspend the carbon nanotubes by using polymer. It is the same composition to the traditional ink. Inkjet printers can use this ink as it can produce patterns, which are electrically conductive.
