  • Patent number: 10416363
    Abstract: A resin molding is provided. The resin molding includes an optically transparent plate-shaped portion which consists essentially of a single material and which includes a first surface having a smooth surface portion, and a second surface having plural convex portions. Each of the plural convex portions includes a first inclined surface having a concavo-convex portion thereon; and a second inclined surface having a smooth surface portion. The concavo-convex portion allows at least part of light incident from the first surface to cause total reflection, diffraction and interference and to travel toward the smooth surface portion of the second inclined surface, and the smooth surface portion selectively reflects visible light in a predetermined wavelength range toward the first surface, so that when the first surface of the resin molding is observed from outside, the resin molding has a colored appearance with at least one color in addition to a metallic appearance.

    Abstract: Printing plates for all-over printing of large areas by the intaglio printing process, a method for producing the printing plates and data carriers, in particular bank notes, with large-area printed images produced by the intaglio printing process area proposed. Flawless inking is ensured by providing partitions in the engraving of the printing plate which rise up vertically from the base of the engraved area and have at least a height of 50% of the engraving depth. The partitions largely prevent ink from being wiped out of the engraved areas when ink is wiped off the printing plate surface. This permits a large printed area to be covered all over with ink layers on a data carrier. By special arrangement and design of the partitions one can also produce fine structures in the printing area which area recognizable only with magnifying aids depending on the selected distances between the partitions.

  • Patent number: 7329111
    Abstract: A device for flowing a liquid on a surface comprises: a flow path. A first port supplies the liquid to one end of the flow path and applies a first port pressure for retaining the liquid when the flow path is remote from the surface. A second port receives the liquid from the other end of the flow path and applies a second port pressure such that the difference between the first and second negative port pressures is oriented to promote flow of the liquid from the first port to the second port via the flow path in response to the flow path being located proximal to the surface and the liquid in the device contacting the surface. The first and second port pressures are such that the liquid is drawn towards at least the second port in response to withdrawal of the flow path from the surface. Such devices may employ microfluidic technology and find application in surface patterning.

  • Patent number: 7275484
    Abstract: A data carrier printed by line intaglio having a halftone image represented by irregular line structures in the manner of an engraving. The line structures are superimposed at least partly by fine structures rendered in positive or negative representation. Methods are provided for generating and processing irregular line structures as digital image data on a computer following individual specifications by an operator. The line structures are transferred to a line intaglio printing plate. The digital image data is used for controlling an engraving apparatus. In the alternative, other printing processes may be involved wherein the digital image data is superimposed at least partly with fine structures rendered in positive or negative representation.

  • Patent number: 7213512
    Abstract: A method for producing a security document having printed image 1 produced by steel intaglio printing and embossed microstructures 2 of an order of magnitude of less than 100 microns is carried out by one printing plate 8 on which both the steel intaglio structures and the microstructures are present. The parts of the microstructures closest to printing plate surface 9 are located 20 to 100 microns below the printing plate surface so that they are not touched and destroyed by the wiping cylinder. Alternative methods for producing a steel intaglio printing plate with integrated microstructures are provided. The microstructures can be used for embossing a diffractive relief or a blind embossing.

  • Patent number: 7063014
    Abstract: A photogravure printing press includes plurality of cells defined by printing-direction walls and substantially perpendicular walls formed in each of image areas on the circumferential surface of a gravure roll. A plurality of substantially perpendicular cuts are formed in each of the substantially perpendicular walls. In the central portion of the image area, each of the substantially perpendicular cuts is formed so as to have a gap greater than the width of each of the printing-direction walls and the substantially perpendicular walls.

  • Patent number: 7028615
    Abstract: A data medium having a printed image is created by the intaglio printing process. The printed image has at least one first ink area with a first ink layer thickness and at least one second ink area with a second ink layer thickness adjacent to the first ink area, such that the ink layer thicknesses are different. The first and second ink areas are separated by a sharp border line invisible on examination with the naked eye, and the ink layer thickness of both ink areas passes through a minimum in the region of the border line.

  • Patent number: 6945169
    Abstract: Apparatus for producing printing plates in particular a blank sleeve-like printing plate, includes a cylinder carrier for receiving a printing plate, the cylinder carrier being held in cantilever fashion at one end in a frame in a mounting and is driven by a motor, it being possible for the printing plate to be pushed onto the carrier cylinder at an opposite side of the latter which faces away from the mounting and is, therefore, more accessible for making printing plate exchange. An image-setting device is moved along the carrier cylinder.
