Researchers have managed to substitute ink water printing
Today, printers are an integral part of life without which the conduct of business and any turnover of documents becomes impossible. In addition, for the printing process use a lot of paper — which is not very good from the point of view of forest preservation, there is another problem — ink. The fact that modern ink for printer are produced with the use of zinc and other compounds that can harm the environment.
But probably this problem is already solved — the enterprising Chinese. Professor Sean Zhang invented an unusual way of saving natural resources — it is proposed to replace the ink with water. And documents look like a regular print, with text that is easy to read. What's the catch, you ask? It is hidden in a special paper. Has developed a special coating that activates the dye molecules, — it is manifested only in contact with water. To get the black color on the paper, it is covered with a special composition, using blue, Magenta gold and purple colors.

Another unusual finding Chinese — reusable paper. The printed characters on the paper during the day. And after just disappear, and paper can be reused.
