Abstract:
1. A process for printing a web substrate in contacting engagement with an external surface of a gravure roll of a contact printing system, the process comprising the steps of: providing said gravure roll with a plurality of discrete cells disposed upon said external surface; contactingly engaging at least a portion of two primary fluids internal to said gravure roll to form a first secondary fluid at a mixing point, said mixing point being located internal to said gravure roll; fluidically displacing said first secondary fluid through at least one channel, said at least one channel extending from said mixing point to a first portion of said plurality of discrete cells and having a single entry point at said mixing point and a single exit point at said first portion of said plurality of discrete cells; displacing said first secondary fluid from each of said first portion of discrete cells onto said web substrate; and, disposing each cell of said first portion of discrete cells being upon said external surface at a different machine direction and cross-machine direction location from an adjacent cell of said first portion of discrete cells; and, wherein a remaining portion of a first of said at least two primary fluids is displaced into a second portion of said plurality of discrete cells without being mixed at said mixing point.
