  • Patent number: 10807357
    Abstract: A method and an apparatus for cold-stamping onto a three dimensional object. In a first step, an adhesive is applied to the object at a first workstation. In a second step, a transfer film is pressed onto the object by a pressing device at a second workstation. At the same time, the adhesive is cured at the second workstation. As a result, the decorative material of the transfer film adheres to the object at the positions on the object which are provided with adhesive. If, following this, the transfer film is removed from the three-dimensional object after being pressed on, the decorative material remains on the object at the desired positions. At the positions at which in the first step no adhesive has been applied to the object, the decorative material does not adhere to the object but rather remains on the carrier film of the transfer film.

  • Patent number: 10752022
    Abstract: Various embodiments concern inkjet printing systems designed for multilayer imaging with a high-gloss clear ink layer. More specifically, the inkjet printing systems are designed so that clear, curable inks are provided additional time to level out before being cured. The settling process enables the inkjet printing systems to produce multilayer images having high gloss values. For example, a bracket could be attached to a curing assembly that prevents radiation from striking a certain portion of the substrate onto which clear ink has recently been deposited. As another example, an inactive array of light-emitting diodes may be disposed in line with the print head(s) responsible for depositing clear ink. Moreover, various embodiments also allow for true multilayer printing of a color coat and a high-gloss clear coat in a single step (e.g., by arranging print heads into rows within a printer carriage).

  • Patent number: 10710382
    Abstract: A printing apparatus includes a feeder that feeds a medium in a feeding direction, a head including a row of nozzles arranged side by side in the feeding direction and movable in a scanning direction, an irradiator that radiates light onto a region longer in the feeding direction than the nozzle row and that is movable in the scanning direction together with the head, and a controller that alternatingly causes the head to move in the scanning direction and concurrently the nozzles to discharge ink while causing the irradiator to radiate the light, and the feeder to feed the medium in the feeding direction. The controller is capable of dividing the nozzle row into an upstream-side nozzle row and a downstream-side nozzle row located on a downstream side in the feeding direction from the upstream-side nozzle row, and individually controlling discharge of ink from the nozzles of each of the upstream-side nozzle row and the downstream-side nozzle row.

  • Patent number: 10703121
    Abstract: A transport mechanism includes a transport belt in which holes are formed and a suction clinging mechanism. The transport mechanism transports the medium in the first transporting direction, and when the upstream edge reaches a switching position, the transport mechanism transports the medium in the second transporting direction and stacks the medium in a stacker. The suction clinging mechanism includes an opening of a first suction chamber and an opening of a second suction chamber, and the opening of the first suction chamber is located downstream of the opening of the second suction chamber in the first transporting direction. The switching position is located upstream of the opening of the first suction chamber in the first transporting direction. In the first transporting direction, the distance from the switching position to the opening of the first suction chamber is longer than the length of each hole.

  • Patent number: 10688809
    Abstract: A printer includes an ultraviolet (UV) curing device having UV light emitting diodes (LEDs) to cure UV curable inks ejected onto a surface after the surface travels past a plurality of printheads in the printer. A UV detector having UV sensors is positioned opposite the UV curing device so the UV sensors and UV LEDs are opposite one another in a one-to-one correspondence. A controller operates the UV curing device to direct UV light into the UV detector and receives electrical signals generated by the UV sensors. The controller compares these electrical signals to a predetermined threshold to identify defective LEDs in the UV curing device. The controller then determines how to move the UV curing device across the path of the surface to irradiate areas of the surface previously opposite the defective UV LEDs.

  • Patent number: 10668743
    Abstract: At least one of an upstream drive roller and a downstream drive roller is operated, after printing on web paper and at a time of transportation halt of the web paper, to make a tension value of the web paper between the upstream drive roller and downstream drive roller lower than a tension value at a time of transporting the web paper, so that at least part of contact portions of the web paper in contact with five cooling rollers separate from the five cooling rollers. Consequently, gaps can be produced between the contact portions of the web paper in contact with the five cooling rollers and the five cooling rollers. This can reduce waterdrops due to dew condensation adhering to the web paper. As a result, paper break can be inhibited at a time of starting transportation of the web paper.

  • Patent number: 10647131
    Abstract: A method for fluid-density modulated auto-duplexing is disclosed. This method determines when a final swath of a printing operation on a surface of a media occurs within a predefined distal end portion of the media. An estimated media dry time after the final swath in the predefined distal end portion is determined to be greater than a predetermined time. The estimated dry time is capped to a predetermined minimum media dry time and a course of action for a feed mechanism is selected to reduce curling and cockling of the media. Furthermore, a non-transitory computer readable medium and a printer having fluid-density modulated auto-duplexing are also disclosed.
