Abstract: Inkjet printing systems are provided that use a cross-module airflow to limit condensation between a printing module and a receiver and that supply a co-linear flow of air that flows along with ink droplets toward a receiver. An integration area is created between the inkjet printhead heads, the receiver and a barrier to allow co-linear flow and cross-module flow to integrate and flow from between the printing module and the receiver without disrupting travel paths of the ink droplets.

Abstract: Inkjet printing methods are provided that deflect and guide a condensation reducing airflow between a printing module and a receiver without disrupting inkjet drop placements and that use surface energy differences to manage any condensation that arises.

Abstract: According to the present invention, a printing system adapted to print on a print side of a print media is disclosed. The printing system comprises one or more vacuum assemblies. Each vacuum assembly has a vacuum manifold disposed opposite a non-print side of the print media. Each vacuum manifold has an opening proximate to the non-print side of the print media and produces a vacuum that pulls the print media towards the vacuum manifold as the print media is moved through the printing system. The vacuum manifold further includes a plurality of edge seals. Each of the edge seals includes a channel for vacuum to be applied to the non-print side of the print media, the channel having at least one opening formed in a print media contact surface of the edge seal connected to at least one opening formed in a side surface of the edge seal.

Abstract: A printing system includes one or more lineheads disposed opposite a first side of a print media and at least one vacuum assembly having a vacuum manifold disposed opposite a second side of the print media. The linehead or lineheads has one or more print zones where a liquid or ink is deposited onto the first side of the print media. The vacuum manifold is aligned with a non-print zone of each linehead and outputs a vacuum force proximate to the second side of the print media such that at least a portion of the second side of the print media is deflected away from the lineheads. The printing system can also include another component, such as a dryer, disposed over the print media and laterally adjacent to the linehead. Another vacuum manifold can be disposed adjacent to the second side print media between the linehead and the component.

Abstract: A digital printing system for printing on a continuous web of print media includes a printhead configured to selectively moisten at least a portion of the web of print media as the web of print media is guided through the printing system. A roller, positioned downstream from the printhead, contacts the print media and causes the print media to wrap around a portion of the roller as the print media moves past the roller. The roller, having an axis of rotation, includes a pattern of recesses and ridges positioned along the axis of rotation of the roller. A second section of the roller is located between a first section of the roller and a third section of the roller as viewed along the axis of rotation. The roller includes a profile as viewed along the axis of rotation in which the diameter of the ridges located in the first section of the roller and the diameter of ridges located in the third section of the roller are greater than the diameter of the ridges located in the second section of the roller.
