Abstract:
1. A printing system for printing an image on a continuous web of recording media moving along a web path comprising: a backer roller configured to support the web of recording media moving along the web path at a first location, the backer roller defining a backer roller plane extending along a tangent substantially parallel to the web path at the first location; a first print module positioned opposite the backer roller, the first print module having a module face that is parallel to the web path, the first print module being configured to eject ink onto the web of recording media passing along the web path between the module face and the backer roller plane as the web of recording media moves over the backer roller at the first location; and a web retraction device disposed along the web path, the web retraction device configured to move between a first position and a second position, the web retraction device at the first position does not contact the backer roller plane and the web of recording media moving over the backer roller as the first print module ejects ink onto the web of recording media at the first location and the web retraction device at the second position contacts the web of recording media and extends through the backer roller plane, while the web of recording media is stationary, at a portion on the web that is prior to the web of recording media reaching the first location and at a portion of the web that is after the web of recording media has passed the first location to increase an amount of the web of recording media in contact with the backer roller over an amount of the web of recording member contacting the backer roller during printing.
