Abstract

A system and method prints on a continuous web of imaging material in a printing machine. One or more inkjet printheads deposit ink on the continuous web of imaging material which is supported by rollers along a transport path. An air film device is disposed between rollers to stabilize flatness the transported web during printing. Undesirable dynamic movement of the web toward or away from the printheads resulting from fluttering, troughing or catenary sag of the web is reduced to minimize drop placement error in both cross-track and process directions.

First claim

What is claimed is:

1. A web transport apparatus for transporting a continuous web of recording media past a printhead the location of which defines a print zone where ink is deposited to image the continuous web comprising:
a first roller configured to transport the web in a process direction through the print zone, the first roller being oriented perpendicular to the process direction through the print zone;
a second roller configured to receive transport the web after the web…
