Abstract
This process is directed to the coloration of envelope and stationery grades of white paper stocks with a water based ink coating. Characteristics of the flexographic process include both press and ink specifications. Critical mechanical or material characteristics are associated with each of the fountain roll, the anilox roll, the plate roll and the impression roll of a flexographic printing system. Used in conjunction with the critical combination of press characteristics is a unique, water-based ink formulation for rapidly coloring an entire web side with a colored ink to simulate the appearance of a colored paper stock.
