摘要： A printing system includes one or more lineheads that jet ink onto a first side of a print media. At least one roller supports a second side of the print media as the print media is transported through the printing system. A roller deformation adjustment mechanism abuts at least one roller and is configured to apply a force to the roller to deform the roller. The deformation of the roller compensates for web skew by changing the relative timing of ink flight times from the linehead to the first side of the print media. The linehead can be disposed on a movable support. The printing system can also include one or more linehead skew adjustment mechanisms configured to move the movable support to adjust a skew of the linehead.

摘要： An automatically-adjusting tensioning mechanism for use in a roll-fed web media transport system, the tensioning mechanism adding tension to the web media, comprising a bracket assembly being adapted to freely pivot around a pivot axis, and first and second tensioning shoe having curved surfaces attached to the bracket assembly. The web media feeds through the tensioning mechanism in an S-shaped media path where the web media is wrapped around the first and second tensioning shoes. The pivot angle of the bracket assembly automatically adjusts in response to differences in a coefficient of friction between the web media and the tensioning shoes such that the tension in the web media has a reduced level of variability relative to configurations where the bracket assembly is held in a fixed position.

摘要： A method for controlling tension in a print media in a tension zone of a printing system comprises enabling an active tension control mode until the tension in the print media is in a stable state for a given period of time. Then, the active tension control mode is disabled and a synchronized control mode is enabled. The tension in the print media is monitored to determine if the tension exceeds a tension inner band but does not exceed a tension outer band while the synchronized control mode is enabled. The speed of a drive roller is adjusted in response to this determination. The tension in the print media is also monitored to determine if the tension exceeds the tension outer band while the synchronized control mode is enabled. The synchronized control mode is disabled in response to this determination and the active tension control mode is enabled.

摘要： A digital printing system, for printing on a continuous web of print media, includes a media operation zone in which an operation is performed on the print media. A support structure guides a continuous web of print media under tension through the media operation zone. The support structure includes a first mechanism and a second mechanism. The first mechanism, located upstream relative to the media operation zone, includes structure that positions the print media in a cross track direction so as to establish center justification of the print media as the print media enters the media operation zone. The second mechanism, located downstream relative to the media operation zone, includes structure that positions the print media in a cross track direction so as to maintain center justification of the print media as the print media travels through the media operation zone.

摘要： In an illumination system for a film telecine scanner of the type adapted to provide a line of illumination on the image frames of a film which is supported for rapid movement in a film gate of the scanner, an improved light control system for adjusting the amount of light that is delivered from a light source to an integrating cylinder to take into account fluctuations in intensity of the light source and desired intensity changes in the line of illumination upon a change of scene in the image frames of the film as the film is being scanned. The light control system includes aperture defining apparatus for selectively adjusting the amount of light entering said integrating cylinder in response to the commanded light intensity signal within the time span of scanning a single image frame of the film. The aperture setting apparatus comprises a housing containing a continuous, single piece, elongated band having first and second centrally disposed light obstructing or solid band sections formed in parallel planes with respect to one another and first and second light transmitting or cut-out band sections separating the first and second light obstructing band sections and forming end loops of the elongated band, the first and second shaped leading edges formed as edges of the first and second light obstructing band sections defining one side of the first and second respective light transmitting band sections which face one another and interrupt the light beam in near the same plane as the first and second light obstructing band sections are moved in parallel with respect to one another and the opening. In order to support and move the elongated band, a tension and return idler assembly supported by the housing engages and provide rotational and tensioning support for the end loop of the first light transmitting section. A motor drive assembly supported by the housing engages and provide rotational driving force to the end loop of the second light transmitting section. Idlers supported by the housing means guide the first light obstructing band section into closely spaced parallel relationship with the second light obstructing band section.

摘要： A method for controlling tension in a print media in a tension zone of a printing system comprises enabling an active tension control mode until the tension in the print media is in a stable state for a given period of time, and then switching to a synchronized control mode. The tension is monitored to determine if it exceeds a tension inner band but does not exceed a tension outer band while in the synchronized control mode. The speed of drive rollers is adjusted in response to this determination. The tension is also monitored to determine if it exceeds the tension outer band while in the synchronized control mode. The synchronized control mode is disabled in response to this determination and the active tension control mode is enabled. The frequency of speed adjustments is lesser in the synchronized control mode than in the active tension control mode.

摘要： A printing system can include a movable support and a linehead disposed on the movable support. The linehead is positioned opposite a print media and jets ink onto a surface of the print media. One or more linehead skew adjustment mechanisms are configured to move the movable support to adjust a skew of the linehead. The printing system can include an imaging system that captures images of the surface of the print media and a processing device that analyzes the images to determine if the print media is skewed and to determine one or more linehead skew adjustment values when the print media is skewed.

摘要： A printing system includes multiple lineheads that each jet ink onto a print media while the print media is transported through the printing system. Imaging devices are positioned to capture one or more images of each side of the print media. A method for correcting for web skew and front-to-back registration includes determining a skew positional error for each color plane in a printing module and determining one or more skew positional correction values based on the skew positional error. A registration positional error can be determined and one or more registration positional correction values can be determined based on the registration positional error. A setting or operation of at least one printing system component is automatically adjusted based on at least one registration positional correction value or at least one skew positional correction value.
