If You Must Print: Go green! Investigate the base material to be printed on looking for something recycled or natural, using low water to be produced, and has low to no toxic chemical waste. Investigate the ink. Veggie ink is best as it is 90%+ reclaimable and made from non-toxic sources. Ink that requires low water processing (used to get indoor and outdoor weathering capability) is the next best choice. Location, location, location… the further you have to ship it, the higher the transportation carbon foot print to get it to you. Ignore the myth green printing does not cost more.
