  • Patent number: 9042632
    Abstract: There is described a method for touchless counting of substantially planar substrates, especially banknotes, which are stacked in the form of stacks of substrates, said method comprising the following steps: taking at least one sample image of a portion of a side of a stack of substrates, which sample image contains contrast information representing substrate edges that extend along substantially a first direction in the sample image; processing the contrast information representing the substrate edges within the sample image (10), which processing includes subjecting at least one area of interest (20) within the sample image (10) to anisotropic diffusion to produce a processed image containing a substantially coherent set of continuous lines representing the substrate edges; and counting the number of substrate edges in said processed image.

  • Patent number: 8230787
    Abstract: An area coverage, which is carried out by a volume of printing ink transferred to a print stock by an inking unit of a printing press, can be adjusted. An ink feed to the inking unit can be disengaged in zones or can be interrupted in the inking and upon reaching of a final phase of a printing process which was previously carried out by the printing press. The volume of printing ink remaining on the print stock after such a disengagement or interruption in the ink feed in the inking unit in the final phase of the printing process previously carried out by the printing press, is transferred to the print stock until the area coverage made by the volume of printing ink transferred to the print stock equals a specified target value of area coverage for an impression of a subsequent printing process. A corresponding method is also provided for execution in a printing press that has a plurality of printing units.

  • Patent number: 8176847
    Abstract: The plausibility of at least one measured value, that is determined in a printing press, and that includes a density of an ink applied to a stock, is assessed. The stock is conveyed through the printing press and the ink is applied to the stock in several inking zones. A relation is formed between a measured ink density value, which is determined for a specific ink in a selected ink zone, and a measured ink density value determined for the same ink in at least one other inking zone. The measured ink density value for the specific ink in the selected ink zone is rejected as being implausible, and is not used for automatically regulating the ink in the printing press, if the relation between the measured value and the measured value for the same ink in the at least one other inking zone inadmissibly either exceeds or lies below at least one predefined threshold value.

  • Patent number: 8100057
    Abstract: The ink in a printing press, in which a stock of material is being printed in an ongoing printing process, is registered. At least one ink is applied to the stock in several inking zones. A measured value, indicating an ink density, is determined for the at least one ink which is being applied to the stock in the printing process and within the printing press. A relation is formed between the measured ink density for a specific ink in a selected ink zone and a measured ink density value determined for the same ink in at least one other inking zone. The relation between the measured ink density values in different inking zones is formed only if the majority of the inking zones of a specific inking unit of the printing press supply one respective measured ink density value for an ink supplied by that inking unit, and when the measured ink density value reaches at least a predetermined fraction of a preset, desired value in the respective inking zone.

  • Patent number: 8001898
    Abstract: A method is used for adapting an inking unit of a printing press. During a setup phase for the printing press, at least a first actual value with regard to an ink application that is set at the inking unit and that is applied to the printed material, is determined by use of a first measuring device. The inking unit is initially set using this first actual value. During continuous printing of the printing press, a plurality of second actual values, with respect to a printed image formed on the printed materials, are determined using a second measuring device which is different from the first measuring device. These second values are fed to an ink adapting device for the inking unit. At least one of these several actual values, which corresponds to the setting mode in the setting phase, is set in the ink adjusting device as its setpoint value. The ink adjusting device detects deviations of the other second actual values for this setpoint value and adjusts the inking unit to minimize these deviations.

  • Patent number: 7672486
    Abstract: The quality of printed matter, which is one of several copies of the same printed matter produced by a printing machine, is evaluated. An amount of copies of the printed matter is selected from the total production of this printed matter. The selected amount of these copies are evaluated with regard to at least one error type which belongs to an amount of different error types or with regard to at least one feature of the error. Within the selected amount of copies, an error of a defined error type or of a defined feature, which is detected on at least one of the copies, is evaluated in relation to at least one error of another type or feature detected on the same copy, or another copy of the selected amount. The printed matter is classified as having good or bad quality based on that evaluation. A common reading, producing image data, is obtained by an image sensor from the selected copies.

  • Patent number: 7664294
    Abstract: A system is provided for inspecting a printed image. The system is provided with at least one evaluation unit, a display device and an image scanner. That scanner takes an image that represents, at least partially, a printed image. The copied printed image belongs to a sequence of images printed on a print carrier by a printing machine. The evaluation unit receives data that is correlated to an image which has been taken, and evaluates that data by comparing it with recorded data of at least one preceding image, or with a reference image. The display device is provided with a graphic display surface that is comprised of several areas which are controlled, in a different manner, by the evaluation unit, and which are preferably simultaneously displayed. A first area displays several images, such as the just taken image, the preceding image and the reference image.

  • Patent number: 7650019
    Abstract: A method is used for the early identification of a deviation in the printed images which have been formed by a printing press during continuous production. A second decision threshold is provided, in addition to a decision regarding good or bad print quality. A current printed image, that has been captured, is compared with a reference image. If the current image deviates from the reference image, that deviation is evaluated using two decision thresholds.

  • Patent number: 7609878
    Abstract: Color deviations of images are analyzed using a sensor. The received image sensor signal is analyzed pixel by pixel. An image sensor signal is produced for each color channel from a plurality of color channels. An image sensor signal from a first channel, and one from a second channel, are combined. An output signal of a first color contrast channel is generated. Now an image sensor signal from a third channel is combined with the ones from the first and second image sensors. An output signal of a second color contrast channel is generated. The outputs of these color contrast channels are classified.

  • Patent number: 7513196
    Abstract: At least one register and an ink density are controlled in a printing machine having at least one printing unit which includes a forme cylinder, a transfer cylinder, and a counter-pressure cylinder. An image sensor records an image from a print substrate, which is imprinted with ink, inside the printing unit, and sends data correlated to that image to an evaluation unit. The data for the last printed image is compared with prior data and in response, the evaluation unit generates a command that is directed to an actuator for controlling the supply of ink. The image sensor is oriented towards the print substrate and detects the entire width of the printed substrate, which width is transverse to a direction of substrate conveyance. The evaluation unit generates the actuating command to control the supply of ink based on data from the image sensor and taken over the entire width of the substrate. The evaluation unit also controls register, based on this data.
