  • Patent number: 11911892
    Abstract: Example methods and devices for touch-down detection for a robotic device are described herein. In an example embodiment, a computing system may receive a force signal due to a force experienced at a limb of a robotic device. The system may receive an output signal from a sensor of the end component of the limb. Responsive to the received signals, the system may determine whether the force signal satisfies a first threshold and determine whether the output signal satisfies a second threshold. Based on at least one of the force signal satisfying the first threshold or the output signal satisfying the second threshold, the system of the robotic device may provide a touch-down output indicating touch-down of the end component of the limb with a portion of an environment.

  • Patent number: 11865830
    Abstract: A method of operating flexographic printing presses having an impression cylinder, printing cylinder carrying a sleeve with a flexographic printing forme or cylinder, uses a sensor adjusting print register of the printing forme or cylinder relative to a further printing forme or cylinder and/or adjusts color density and/or implements color inspection. An image of the sleeve surface with printing forme is recorded by a camera and processed before printing, locating a register mark and/or a color measurement field in terms of x-y positions. A sensor automatically moves for recording the register mark to the y-position of the register mark before adjusting to record the register mark and/or a sensor moves for recording the color measurement field to the y-position of the color measurement field before adjusting to record the color measurement field. Cost-efficient, high-quality industrial printing and further automation is provided.

  • Patent number: 11801674
    Abstract: An optical gloss meter above an imaging member surface measures fountain solution surface gloss on the imaging member surface in real-time during a printing operation. The measured gloss corresponds to a thickness of the fountain solution layer and may be used in a feedback loop to actively control fountain solution layer thickness by adjusting the volumetric feed rate of fountain solution added onto the imaging member surface during a printing operation to reach a desired uniform thickness for the printing. This fountain solution monitoring system may be fully automated.

  • Patent number: 11787167
    Abstract: Ink-based digital printing systems useful for ink printing include a secondary roller having a rotatable reimageable surface layer configured to receive fountain solution. The fountain solution layer is patterned on the secondary roller and then partially transferred to an imaging blanket, where the fountain solution image is inked. The resulting ink image may be transferred to a print substrate. To achieve a very high-resolution (e.g., 1200-dpi, over 900-dpi) print with these secondary roller configurations, an equivalent very high-resolution fountain solution image needs to be transferred from the secondary roller onto the imaging blanket. To increase the resolution of the image on the secondary roller, examples include a textured surface layer added to the secondary roller for contact angle pinning the fountain solution on the roll. Approaches to introduce a micro-structure onto the surface layer of the secondary roller, and also superoleophobic surface coatings are described.

  • Patent number: 11787166
    Abstract: A formative surface having a conductive base covered with a dielectric and oleophobic/hydrophobic surface layer is created with defined pits to grow micro-puddles of a defined volume. The formative surface is brought into close proximity with a charge retentive surface carrying a charge image. Fountain solution vapor nucleates and grows preferentially on the base of the pits as micro-puddle droplets. The puddles are charged and extracted from the surface to provide a fog of charged droplets of narrow volume and charge distribution. The charged droplets are attracted and repelled respectively from the charged and discharged image regions of the charge retentive surface, thus developing the charged image into a fountain solution latent image. The developed latent image is then brought into contact with a transfer member blanket and split, thus creating on the blanket a fountain solution latent image ready for inking.

  • Patent number: 11752756
    Abstract: A method of operating a flexographic printing press having a printing cylinder carrying a sleeve with at least one flexographic printing forme or a flexographic printing cylinder, and an impression cylinder, includes adjusting contact pressure between the printing cylinder or the flexographic printing cylinder and the impression cylinder by motor. The adjustment is made in an automated way as a function of a dot density of the flexographic printing forme, i.e. of a location-dependent density of printing elevations on the flexographic printing forme or data computationally derived therefrom. A cost-efficient way of producing high-quality prints in an industrial flexographic printing process is thus provided. In addition, the method advantageously provides further automation of the printing process. A flexographic printing press, a flexographic printing press system, and a flexographic printing forme or sleeve for a flexographic printing forme are also provided.

  • Patent number: 11745495
    Abstract: Disclosed is a corrugated paperboard printer comprising a pressing device for applying a pressing force to press a chamber which reserves ink toward an anilox roll. The pressing device is configured to apply a first pressing force, and a second pressing force which is greater than the first pressing force, respectively, to a first pressing area and a second pressing area in a back surface of a chamber frame. In a state in which no pressing force is applied by the pressing device, bending occurring in the chamber frame due to a load transmitted from a printing roll to the chamber frame via the anilox roll as printing is performed to a corrugated paperboard sheet is greater in the second pressing area than in the first pressing area.
