Cartons canabsorb extra moisture if placed on the floor.• Store paper in a climate controlled room, if possible. Most airconditioning systems provide a good mix of temperature andhumidity. Paper will perform best if the storage area isbetween 68° and 76°F (20° and 24°C) with 35 to 55% relativehumidity.
