The engineers at ASPE Inc made the perfect can cooler printing machine. The machine you see in this video will print on one side of a can cooler then flip the product 180 degrees in order to print on the other side. It also automatically takes off the can cooler. Pallet size is dependant on the material the can cooler is made out of. Usually the pallets are about 3.75 inches wide for a foam can cooler and about 3.5 inches for a neoprene can cooler.
