3R-reduce,reuse and recycle. This basic theory of green design. Reduce, the best reduce is no use.So I think about no ink. If we don't use ink, that must be green more. But I thnk that is impossible. How could we do not use ink and we can see the information. I thought about the tiny hole by needle. Firstly people see the paper or the light decorated by the little needle hole, we always think that is just decoration. But sometime it it not. It is also green way to communication.
