Abstract

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.

First claim

What is claimed:

1. A system for printing 7 or more inks on a substrate, the system comprising:
6 or less rotating rolls disposed in operative relationship with a substrate, wherein each of the rotating rolls comprise:
a central longitudinal axis, wherein the rotating roll rotates about the central longitudinal axis;
an exterior surface defining an interior region and substantially surrounding the central longitudinal axis;
a vascular network configured for transporting at least one of the 7 or more inks in a predetermined path from the interior region to the exterior surface of the rotating roll, the vascular network comprising at least one main artery, at least one capillary and a plurality of fluid exits on the exterior surface, wherein:
the at least one main artery comprises an inlet and is substantially parallel to the central longitudinal axis of the rotating roll, wherein the fluid enters the vascular network at the inlet; and
wherein the at least one capillary is attached to the at least one main artery and is in fluid communication with the at least one main artery and at least two fluid exits through a substantially radial fluid path, the substantially radial fluid path having a radial vector component along essentially the entire path and the capillary expanding both axially and circumferentially in a radial direction from the main artery to the exterior surface of the rotating roll.

2. The system of claim 1 wherein at least one of the 7 or more inks is registered with a product feature.

3. A system for printing 3 or more inks on a substrate, the system comprising:
a rotating roll comprising:
a central longitudinal axis, wherein the rotating roll rotates about the central longitudinal axis;
an exterior surface defining an interior region and substantially surrounding the central longitudinal axis;
a vascular network configured for transporting the 3 or more inks in a predetermined path from the interior region to the exterior surface of the rotating roll, the vascular network comprising a plurality of main arteries, a plurality of capillaries and a plurality of fluid exits on the exterior surface, wherein:

each main artery comprises an inlet and is substantially parallel to the central longitudinal axis of the rotating roll, wherein the fluid enters the vascular network at the inlet; and
wherein each capillary is attached to one of the main arteries and is in fluid communication with one of the main arteries and at least one fluid exit through a substantially radial fluid path, the substantially radial fluid path having a radial vector component along essentially the entire path and the capillary expanding both axially and circumferentially in a radial direction from the main artery to the exterior surface of the rotating roll.

4. The system of claim 3 further comprising an internal mixer associated with at least two inks.
