The best form of resource sparing use of paper is printing on both sides in my eyes. The work with this paper well. Only with pictures a very light shining through is visible. Second advantage is that the paper is really white, just for colored the result is good. Third advantage: It has something in his hand: The paper feels solid and high quality, even though only 80 g for correspondence very suitable.. I use it with an inkjet printer and am very satisfied.
