    摘要： Embodiments described herein are directed to a system for reducing electrostatic fields underneath print heads in a direct marking printing system. The system includes: one or more print heads for depositing ink onto a media substrate; a media transport for moving the media substrate along a media path past the one or more print heads; a conductive platen contacting the media transport belt; and an electrostatic field reducer that includes an alternating current corona device positioned upstream of the one or more print heads. The media transport includes a media transport belt and, when the media substrate is on the transport belt it has an electrostatic field, which can cause printing defects. The electrostatic field reducer reduces the electrostatic field on the surface of the media substrate and thereby reduces printing defects.

    摘要： A system and corresponding methods are disclosed for controlling the thickness of a layer of dampening fluid applied to a reimageable surface of an imaging member in a variable data lithography system. Following deposition of the dampening fluid layer, a gas is passed over a region of the fluid layer prior to pattern forming. The gas causes a controlled amount of the dampening fluid layer to evaporate such that the remaining layer is of a desired and controlled thickness. Among other advantages, improved print quality is obtained.

    摘要： A steel rule die making system produces a steel rule dies having an operative surface that form creases and cut patterns in a sheet material to form a box blank. The system includes a die manufacturing station having an indexing bench that securely holds a substrate. At least one slug driver device is disposed adjacent the die manufacturing station to drive the penetrating point of a slug into the substrate. The upper surface of the slug head defines a segment of the operative surface of the steel rule die.

    摘要： A method and system move a media sheet in a processing direction of a media path from a first nip to a second nip and move the media sheet in the processing direction of the media path from the second nip to a third nip. The method senses, using a sensor positioned between the second nip and the third nip, the position of the media sheet relative to the sensor. The method automatically calculates the amount of curl the media sheet contains based on the difference between the predetermined position and the position of the leading edge of the media sheet (relative to the sensor) as the leading edge of the media sheet passes between the second nip and the third nip, using the processor. Further, the method automatically calculates the thickness of the media sheet based on the difference between the predetermined position and the position of the media sheet (relative to the sensor) as the media sheet passes between the second nip and the third nip, using the processor.
