1. A contact printing system comprising:
a gravure cylinder having a plurality of discrete cells having an aspect ratio of at least about 25:1 disposed upon an outer surface thereof, a first portion of said plurality of discrete cells receiving a first portion of a first fluid from a first at least one channel disposed internal to said gravure cylinder and extending from a first position external to said gravure cylinder to said first portion of said plurality of discrete cells; a second portion of said plurality of discrete cells receiving a second fluid from a second at least one channel disposed internal to said gravure cylinder and extending from a second position external to said gravure cylinder to said second portion of said plurality of discrete cells; said first and second at least one channels each having a single entry point at said respective first and second position external to said gravure cylinder and a discrete exit point at said respective first and second portion of discrete cells of said plurality of discrete cells; said first and second portions of discrete cells being disposed adjacent each other upon said outer surface of said gravure cylinder; wherein a second portion of said first fluid is disposable from said first at least one channel to a third portion of said plurality of discrete cells; wherein a first and second portion of said first at least one channel supplies said first and second portions of said first fluid to each of said first and third portions of said discrete cells, respectively.
