A system for printing 7 or more inks on a substrate is disclosed. The system can include: 6 or less rotating rolls disposed in operative relationship with a substrate, wherein each of the rotating rolls can comprise a vascular network configured for transporting at least one of the 7 or more inks in a predetermined path from an interior region to an exterior surface of the rotating roll. The vascular network can have at least one main artery, at least one capillary and a plurality of fluid exits on the exterior surface. At least one capillary is attached to a main artery and is in fluid communication with at least two fluid exits through a substantially radial fluid path to form a tree.
