Earth Day Tip #2 comes courtesy of Mohawk Paper. To get the most out of your press sheet with as little waste as possible, start with the end in mind. Working backwards from stock size press sheets (ex. 26x40), determine the most efficient final size of your piece - before you design it. Ask your printer for help when it comes to planning for allowances like gripper margins, grain direction, bleeds, etc.
You can also minimize the impact of waste by "ganging up" print runs. And for even more efficiency, take advantage of Millcraft's custom sheeting operation, Deltacraft, to order a special sheet size - but make sure to plan ahead, this usually requires lead time.
