Abstract

A contact printing system is disclosed. The contact printing system can print X colors upon a web substrate in the machine direction. The contact printing system has X-Y printing components where X and Y are whole numbers, 0<Y<X, and X>1.

First claim

What is claimed is:

1. A contact printing system for printing X colors upon a web substrate having a machine direction and a cross-machine direction orthogonal and co-planer thereto, said contact printing system comprising:
X-Y printing components where X and Y are whole numbers, 0<y<X, and X>1,
each of said printing components comprising a gravure cylinder having a plurality of discrete gravure cells disposed within a surface thereof and each having a defined position relative to said machine and/or cross-machine directions upon said surface, and at least one fluid disposed internally thereto,
a first portion of a first of said at least one fluid being displaceable into a first portion of gravure cells of said plurality of discrete gravure cells from at least one channel extending from a position external to said gravure cylinder,
a second portion of said first of said at least one fluid being displaceable into a second portion of gravure cells of said plurality of discrete gravure cells from said at least one channel,
said at least one channel having a single entry point at said position external to said gravure cylinder and a discrete exit point at each of said first and second portions of gravure cells, and
wherein a first and second portion of said at least one channel supplies said first and second portions of said first of said at least one fluid to each of said first and second portions of gravure cells, respectively.

2. The contact printing system of claim 1 wherein said at least one fluid is fluidly communicateable from said surface of said gravure cylinder to said web substrate when said web substrate is in contacting engagement with said surface of said gravure cylinder.

3. The contact printing system of claim 1 , wherein said first portion of said plurality of discrete gravure cells is capable of being supplied with said first of said at least one fluid from a first position internal to said gravure cylinder, and a third portion of said plurality of discrete gravure cells is capable of being supplied with a second of said at least one fluid from a second position internal to said gravure cylinder, said first and second of said at least one fluid being different, each of said first and second of said at least one fluid being fluidly communicatable from each respective position internal to said gravure cylinder to said surface of said gravure cylinder.

4. The contact printing system of claim 3 wherein each of said first and second of said at least one fluid are fluidly communicatable to said respective first and second positions from a position external to said gravure cylinder.

5. The contact printing system of claim 3 wherein each of said first and second of said at least one fluid are fluidly communicateable from said surface of said gravure cylinder to said web substrate when said web substrate is in contacting engagement with said surface of said gravure cylinder.

6. The contact printing system of claim 1 wherein said plurality of discrete gravure cells disposed upon said surface of said gravure cylinder are arranged in an array.

7. The contact printing system of claim 6 wherein said array is a pattern.

8. The contact printing system of claim 1 wherein said plurality of discrete gravure cells disposed upon said surface of said gravure cylinder comprises a first plurality of discrete gravure cells arranged in a first array and a second plurality of discrete gravure cells arranged in a second array.

9. The contact printing system of claim 8 wherein said first array is a first pattern and said second array is a second pattern, said first and second patterns being different.

10. The contact printing system of claim 1 wherein said gravure cylinder is formed such that said gravure cylinder has a unibody construction.

11. The contact printing system of claim 1 where X=2 and Y=1.

12. The contact printing system of claim 1 where X=4 and Y=1.

13. The contact printing system of claim 1 where X=8 and Y=1.
