  • Patent number: 10623605
    Abstract: A method for image inspection of printed products in a printing material processing machine includes using an image sensor to capture and digitize printed products during image inspection by an image capture system, using a computer to carry out a comparison of captured digital printed images with a digital reference image, examining a result of the comparison for image regions with blurry regions in the captured digital printed image, calculating suitable smoothing factors for the blurry image regions, and then carry out smoothing of the digital reference image with the calculated, suitable smoothing factors for the blurry image regions, causing the digital reference image to have a blurriness comparable to the captured digital printed image in the image regions. Printed products detected as faulty are removed upon an occurrence of deviations of the captured digital printed image from the digital reference image.

  • Publication number: 20200079119
    Abstract: A method for automated alignment and register measurement in a printing press provides for test patterns having multiple color separations to be printed by the printing press on a printing substrate, recorded by using at least one image sensor of an image acquisition system as a digital overall image, evaluated by a computer with respect to an alignment/register offset and then corrected by the computer for the alignment/register offset. Circular measuring marks having known diameter for each color separation are integrated into the test patterns and the computer ascertains the center position of each circular measuring mark with subpixel accuracy and thus computes the alignment/register offset by cutting out an image region having at least one circular measuring mark from the digital overall image and determining parameters of a model of a printing point of the circular measuring mark from the digital overall image.

  • Publication number: 20190291409
    Abstract: A method for image inspection on printed products in a printing material processing machine. Printed products are recorded and digitizing and the recorded images are compared with a digital reference image to find image areas with distorted regions. Suitable rectification factors are calculated and the digital reference image is rectified with suitable rectification factors for the distorted image areas. The modified digital reference image is then compared to images recorded during the production run. If deviations are found, the printed products are found defective and removed. The computer also identifies image areas in the reference image that do not have enough edges for calculating suitable rectification factors and inserts anchors into the image areas. The anchors are printed, recorded and digitized, as they become part of the recorded digital printed image. In that case, the computer calculates the local rectification factors by way of the anchors.

  • Patent number: 9878485
    Abstract: For the production of embossed microstructures in radiation-curing materials, use is made of a micro embossing form fixed to a reflective or scattering cylinder surface. Via a press nip, the micro embossing form comes into contact with the substrate guided over a cylinder or a deflection roller. The radiation-curing material is acted on in one or both pockets, before or after the press nip, with radiation which penetrates into the press nip by reflection or scattering.

  • Patent number: 9573359
    Abstract: A method and a device for producing and transferring diffractive microstructures to a printing material include applying a fluid to an embossing cylinder and there, during the rotation of the embossing cylinder, solidifying the fluid to such an extent that the fluid is transferred to a printing material in the manner of a film with a solidified microstructure. The embossing cylinder has a cover which is preferably constructed to be either soft as a “flexoshim” or hard as a “nickel shim.” A web-fed or sheet-fed rotary printing press having the device is also provided.

  • Patent number: 8901942
    Abstract: A system for locating and identifying at least two separate items, for example packaging, includes a capacitive first sensor detecting a first measuring region at a first position of a sensor device, for example a sensor film on a shelf bottom for packaging, a capacitive second sensor detecting a second measuring region at a second position, differing from the first position, of the sensor device, an electrically conductive first mark of a first item in the measuring region of one sensor, an electrically conductive second mark of a second item in the measuring region of the other sensor, and an evaluation device evaluating signals from the sensors, the signals caused or changed by electrical conductivity of the marks. Items can be capacitively detected and information obtained can be used to improve warehousing. The sensors and the marks can be produced quickly and cost-effectively by printing processes or film transfer.

  • Publication number: 20100259134
    Abstract: The invention relates to a piezoelectric actuator having a multi-layered structure of piezo-layers in a piezo element and inner electrodes that are arranged between the piezo-layers. The electrodes are alternatively supplied with an electric voltage of a different polarity in the direction of the layer structure of the piezoelectric element. The alternate lateral contacting of the inner electrodes is achieved via outer electrodes and/or a baked base metallic coating of the lateral surfaces. The respective outer electrodes include a bending coil which is wound from a contactable material. During baking of the base metallic coating the contactable material is applied together with at least parts of the bending coil to the coating in a conductive manner. A flexible sheet metal part that has first been provided with cut sections and/or pre-stamped sections can also be used as an outer electrode.

  • Publication number: 20100156251
    Abstract: The invention relates to a method for producing a piezoelectric actuator in which a metallization paste is applied to a sintered piezoelectric stack and a flexible metal electrode is arranged on top of the paste. In a subsequent baking or firing step, a base metallic coating is formed from the metallization paste, whereby the base coating is permanently connected to the piezoelectric stack and to the flexible metal electrode. Alternatively, the metallization paste can be applied to a green body which is subsequently sintered so that a first layer of a base metallic coating is formed in the sintering step. A metallization paste is applied to the first layer in a similar manner and a flexible metal electrode is arranged thereon, whereby the metal electrode becomes fixed during a second baking step.
