Abstract
In a method and apparatus for duplex inkjet printing on a web medium, a web medium is guided along an S-form transport path having generally horizontal top, middle and bottom spans and two turns linking the spans. One inkjet printhead is located to print onto a one surface of the web at the middle span and another inkjet printhead is located to print onto the opposite surface of the web at one of the other spans. To protect the printed surfaces before they are dried at least one of the turns in the S-form path is effected using an air bar to hold the printed web surfaces away from hard equipment surfaces.
