Abstract: A manufacturing line for making corrugated paper has both a conventional feed stock location where stock is fed to the line and a gluing station where the stock is connected to the corrugated medium. The line includes multiple in-line printers that are positioned between the feed stock location and the gluing station. One printer can be used to print a first color or coating on a first portion of the stock, and another printer can be used to print a second color on a second portion of the stock. A center trim pickup can be used to divide the paper stock between the two portions.
