Designer tweaks famous logos to use less ink

Designer tweaks famous logos to use less ink is a great article and I 100% promote it. At first when I read about them reducing energy cost and power consumption I was shocked. Normally famous brands completely ignore this. So this article got my attention right away. But then they said that printing cost more than perfume by on average costing up to $18 dollars for a logo. This really gave me awarness on two things. One how much it will cost to make a logo and two awarness on the importance of saving ink.
