Definitions

  • the present invention relates to an intaglio printing plate, used by example for printing securities such as banknotes, checks and other similar documents.
  • intaglio printing is well known in the state of the art, especially for printing securities.
  • a plate print is etched to form a predetermined pattern and the etchings are then filled with ink which will be transferred to the printed medium, for example paper, which is deformed by pressure by means of a cylinder, having an elastic surface, in the plate engravings.
  • the surface of the paper entering the engravings is thus marked with ink which was previously deposited in said engravings.
  • intaglio printing plate As an example of an intaglio printing plate, reference is made to US Patent 4,036,130, the content of which is incorporated by reference into the this request. Such a plate, usually made of metal, is engraved to form a determined design and can receive an additional hardened layer.
  • application DE 196 24 131 describes another automated plate manufacturing process intaglio printing using a laser.
  • Patent application DE 198 45 440 shows another production of plates intaglio printing unit for flatbed printing, the described plates comprising engravings the bottom of which has partitions forming channels or chambers allowing the ink to be transferred in a vertical direction only, i.e. perpendicular to the surface of the plate, and not in a horizontal or diagonal direction.
  • These channels also allow modulation of the thickness of the ink deposited on the printed medium.
  • patent application DE 198 45 436 describes an intaglio printing process, in which the intensity of the same printed color varies. This effect is obtained by engraving the plate, the depth of which varies so that the quantity of ink in the engraving also varies so that the quantity of ink transferred to the printed substrate is different, thus creating varying intensities.
  • the production rate of these intaglio printing machines can go up up to 10,000 sheets per hour which typically corresponds to a linear speed 2.8 meters / second.
  • the ink deposited in the sizes of the plate therefore undergoes several forces, one perpendicular to the direction of movement of the plate, and the other centrifugal due to the rotation of the plate around the axis of the plate cylinder.
  • the ink will move backwards from the waist into the plate by relative to the direction of rotation and will also be drawn outside the waist instead of stay at the bottom of it, which results in a lower quality print and a irregular paper inking.
  • the object of the invention is to remedy these drawbacks by improving the plates of known impressions.
  • one of the aims of the invention is to propose a plate intaglio printing allowing quality inking despite the fact that inking is done in a moving system.
  • Figure 1 shows a schematic sectional view of an intaglio printing plate according to the state of the art.
  • Figure 2 shows a schematic sectional view of an intaglio printing plate according to a first embodiment of the invention.
  • Figure 3 shows a schematic sectional view of an intaglio printing plate according to a second embodiment.
  • Figure 4 shows a schematic sectional view of an intaglio printing plate according to a third embodiment of the invention.
  • the plate 1 mainly comprises a external surface 2 in which an engraving 3 has been created.
  • ink 4 is deposited for use in marking the substrate, for example paper, printed.
  • the rotation of the plate is schematically represented by the arrow referenced R and the forces which act on the ink, during the production of substrate intaglio printed, by the arrows referenced f1 and f2 whose resultant f12 is actually directed as shown in the figure.
  • the first embodiment of the ink retaining means 4 are represented. These means have the form of slots 6 and are mainly arranged on the rear part of the engraving 3 with respect to the direction of rotation shown diagrammatically by the arrow A. These slots thus make it possible to retain the ink in the engraving and to oppose effectively to the effects of the resulting f12 as shown in Figure 1.
  • FIG. 3 Another embodiment of the retaining means is shown in Figure 3.
  • the means take the form of a toothing 7 cut in the rear part of the engraving 3 relative to the direction of rotation R of the plate 1.
  • the retaining means have the shape of a hollow 8 distributed in engraving 3, on its rear part relative to the direction of rotation R of the plate 1.
  • Such a printing plate can then be mounted without other in one of the machines known from US Patents 5,062,359 and US 5,899,145 incorporated in the this request.
