APPARATUS FOR APPLYING INDICIA HAVING A LARGE COLOR GAMUT ON WEB SUBSTRATES
First Claim
1. A contact printing system comprising a central roll comprising a plurality of discrete cells disposed upon an outer surface thereof, wherein adjacent cells of said plurality of discrete cells each have a fluid disposed therein from a respective location internal to said central roll and wherein each fluid is disposable from each of said cells to a web substrate and provides a resultant color upon said web substrate having a 2-D gamut boundary represented by the following CIELab equations:

Abstract
A contact printing system is disclosed. The contact printing system has a central roll having a plurality of discrete cells disposed upon an outer surface thereof. Adjacent cells of the plurality of discrete cells each have a fluid disposed therein from a respective location internal to the central roll. Each fluid is disposable from each of the cells to a web substrate and provides a resultant color upon the web substrate having a 2-D gamut boundary represented by a defined system of CIELab equations.
