    摘要： In some examples, a screen printing unit includes a screen printing forme cylinder, an impression cylinder, and at least one further rotational transport body. A fixing element of the impression cylinder includes inner and outer contact surfaces for clamping sheets. The inner contact surface has a base radius as a distance from an axis of rotation of the impression cylinder. A cylinder barrel of the impression cylinder has a supporting surface for sheets that includes an impression portion having a constant barrel radius, which extends over at least 170° about the axis of rotation of the impression cylinder and the barrel radius is larger than the base radius. A fixing element of the further rotational transport body includes an inner and an outer contact surface for clamping sheets. The inner contact surface includes the base radius as a distance from an axis of rotation of the further rotational transport body.

    摘要： A mounting unit, or printing system including a mounting unit, for mounting printing plate segments on a carrier sheet. The mounting unit includes a base for receiving the carrier sheet, at least two cameras, a controller for positioning the cameras relative to the base, and a computer connected to the controller and cameras. The computer is configured to receive a mounting file including a printing plate segment identifier, information regarding alignment of registration marks relative to the carrier sheet; and image data corresponding to a characteristic pattern associated with each printing plate segment. The unit is configured to display a composite image depicting the image data corresponding to the characteristic patterns in a predetermined arrangement of printing plate segment locations and orientations overlaid on an image of the carrier sheet from one of the at least two cameras.

    摘要： The machine comprises: a plurality of printing units each of which has a printing cylinder movable so as to allow adjustment of the position of the image printed by that cylinder in two perpendicular adjustment directions relative to the web of printing material; first manually-operated adjustment means arranged to allow a user to adjust manually the position of each printing cylinder; image acquisition means arranged to acquire images of register marks printed by the printing units along one or both sides of the web of material; and display means arranged to show, on an enlarged scale, the images acquired by the image acquisition means, so as to allow the user to detect any misalignments between the register marks and to properly adjust the position of one or more printing cylinders to clear said misalignments. The image acquisition means comprise a plurality of cameras each of which is arranged to frame.

    摘要： A processing machine for processing sheets comprises at least one application unit and at least one sheet sensor associated with that application unit. The at least one sheet sensor is arranged upstream of the associated application unit, along a transport path for sheets. The at least one sheet sensor is configured to detect the arrival time of sheets as the position of the sheet sensor. The at least one application unit, in each case, comprises at least one printing couple having a forme cylinder and an individual drive which is associated to that forme cylinder. The at least one sheet sensor is configured to control the position or the rotational speed of the forme cylinder in one of a closed loop or an open loop. The invention also relates to a method for processing sheets.

    摘要： Example implementations relate to determining a correction factor that converts a measured sensor distance to a calibrated sensor distance. The measured sensor distance may be based on an amount of substrate advancement through a web printing press between detecting a mark on the substrate at a first sensor and detecting the mark at a second sensor. The calibrated sensor distance may be the separation between the first sensor and the second sensor.

    摘要： A can decorator having a blanket wheel and a plurality inking stations. Each of one or more of the inking stations comprises a rotatable shaft geared to the blanket wheel, a print cylinder mounted on the shaft for rotation with the shaft during printing operations, and an adjustment mechanism for adjusting the angular position of the print cylinder on the rotatable shaft during set-up and for fixing the angular position for printing operations. There is further provided a rotary encoder for determining the angular position of the print cylinder relative to the rotatable shaft during set-up and for providing an electrical signal indicative of the angular position to an operator interface device.

    摘要： Example systems and related methods may provide improved defect detection and resolution for a plurality of printing devices. An example method includes receiving information indicative of at least one aspect of a printing device from among a plurality of printing devices. The plurality of printing devices is communicatively coupled to a server. Each printing device of the plurality of printing devices includes a sensor configured to provide information indicative of at least one aspect of the respective printing device. The method also includes, based on the received information, accumulating, at the server, historical data corresponding to the at least one aspect of the plurality of printing devices. The method yet further includes comparing the accumulated historical data with model reference data. The method additionally includes, based on the comparison, determining highlighted data and causing a display device to display the highlighted data.
