  • Patent number: 9678385
    Abstract: An apparatus for manufacturing an alignment layer includes: a dispenser which supplies an alignment material; an anilox roll, onto which the alignment material supplied from the dispenser is applied; a printing roll which is engaged and rotated with the anilox roll; and a resin plate attached to an outer peripheral surface of the printing roll, where the resin plate receives the alignment material applied onto the anilox roll and prints the alignment material to a targeted substrate, in which the resin plate comprises a first area and a second area surrounding the first area, first convex portions and first concave portions are disposed in the first area, second convex portions and second concave portions are disposed in the second area, and an area of each second convex portion is larger than an area of each first convex portion.

  • Patent number: 8172968
    Abstract: The invention relates to a method for contacting a flexible sheet to a first element with improved lateral alignment. The method includes a step of measuring a first lateral misalignment after establishing a first contact between the flexible sheet and either of the first element and a sheet parking surface called anchor in the first stage. If the 5 misalignment exceeds a predetermined threshold the flexible sheet is parked at the anchor such that it is not in contact with the first element, and the relative position of the first element and the anchor is altered during the second stage for correcting the mismatch during a contact between the flexible sheet and the first element to be established within the next step of the method. During the steps of shifting the contact point to obtain the second stage 10 the contacting process is more accurate and reproducible than the process for establishing the initial contact.

  • Publication number: 20110120329
    Abstract: A method and apparatus for high-speed roll-to-roll printing, ensuring high-precision printing previously available only under a static condition. In the present invention, a pattern mask is wound on a print roll, and an ink injector and the roll are configured to maintain a substantially zero linear speed difference between the pattern mask and a print substrate at the moment the ink injector injects ink onto the print substrate through a perforated pattern in the pattern mask. The ink injector may be mounted on the print roll, may rotate separately from the rotating roll with a different rotational speed and direction, and may axially move to ensure no relative movement existing between the pattern mask and the substrate at the moment of printing. The roll may move linearly in the same direction as the substrate. A position sensor may be employed for more precise alignment between substrates in a multilayer printing.

  • Publication number: 20090120311
    Abstract: A roller pad printer for printing on an associated object includes a frame, a flat cliché operably mounted to the frame for receiving and a resilient roller pad operably mount to the frame for rolling contact, at a first location and in a first direction along the cliché, to receive ink transferred from the cliché. The roller pad is adapted for rolling contact with the object, at a second location and in a second direction, to transfer the ink from the roller pad to the object.

  • Patent number: 7516697
    Abstract: An object is to provide a single color press which shortens takt time by eliminating wastefulness from the printing process. There is provided: a first transfer cylinder which transfers an image to a first printing substrate; a first moving carriage which holds the first transfer cylinder in a rotatable manner and travels along a frame; a second transfer cylinder which transfers an image of the same color and shape to a second printing substrate; a second moving carriage which holds the second transfer cylinder in a rotatable manner and travels along the frame 3; and a single relief plate which removes a reverse image from ink applied to the first transfer cylinder and the second transfer cylinder.

  • Patent number: 6792856
    Abstract: Disclosed is a printing apparatus, having a print surface lying in a print plane defined by an imaginary x-axis and y-axis, the print surface having an outward normal pointing in the positive direction along an imaginary z-axis, such that the x-axis, y-axis, and z-axis are substantially orthogonal to one another, a lower stamp clamp disposed adjacent to the negative-x edge of the print surface, an upper stamp clamp, moveable in two dimensions in a trajectory plane defined by the x-axis and z-axis, a stamp comprising a flexible material, the stamp having a first end attached to the lower stamp clamp and a second end attached to the upper stamp clamp, such that a cross section of the stamp parallel to the trajectory plane forms an arc extending from an origin point Q on the lower stamp clamp having (x,z) coordinates (0,0) to point E on the upper stamp clamp, this arc being described by the mathematical function &thgr;(s), where s is the curvilinear distance along the arc measured from point Q, and &thgr; is the
