Definitions

  • the invention relates to a screen for printing, or the like, comprising a screen skeleton in the form of a fine mesh and a further layer of metal electrolytically deposited upon the screen skeleton.
  • Such screen materials are known from DE-B-1 141 295 and WO 80/00677. In said publications is described a process for variably closing the openings in a wire-gauze material, for instance by electrode-position of metal.
  • Such a known material has as a drawback that the material still essentially has a gauze character which may lead to a reduced sharpness of the edges of a pattern printed with such a material which shows up in the form of a saw-teeth profile of said edges.
  • screen material is known to be used in the form of a woven polyester gauze, said polyester gauze meeting the requirements of the fineness desired.
  • Said known screen material presents the drawback that at all times it has to be kept in store under tension mounted on frames. This requires large storage facilities, since a particular screen material which, for instance, is not being used for a long time, must nevertheless be stored in the pretensioned condition on a frame.
  • Another-drawback is that, after providing the woven polyester gauze with holes, this gauze loses its dimensional stability, thus precluding the possibility of meeting the requirements applicable to a particular printing.
  • a further drawback is that the known screen material does not very well assume its original condition after having been used, so that when using such screen material the quality of the product being printed greatly decreases after a relatively short period of time.
  • Still another drawback is that cross threads and weft threads of the woven polyester gauze are not anchored with each other, so that, when using a screen having screen openings of 400 mesh, it frequently occurs that a large number of openings have dimensions that differ from those desired.
  • said screen material has to retain its dimensional stability and to provide for unlimited useability.
  • the screen skeleton having a semi-circular cross section and a flat bottom and the screen having a fineness of between 250 and 1000 mesh; the upper side of the screen openings having an area which is larger than the lower side of the screen openings; each of the screen openings being defined by curved walls extending from the lower side of the screen opening to the upper side of the screen opening; said screen material being obtained by passing the bath solution, at least during part of the electrolytic depositing time, from the bottom side of said skeleton through the openings in the screen skeleton (3) connected as the cathode.
  • EP-A-0 049 022 Concerning the invention mention is made of EP-A-0 049 022.
  • a screen material is described having the same type of cross section of the lands as shown in Figure 2 of the application.
  • the type of screen in this publication is however intended for use as a filter medium, as appears from the introductory part of the description.
  • the screens however are gauze type materials structured from stainless steel wire. This type of gauze screens show all disadvantages of lack of definition, stability etc. for which the screens of the invention offer a solution.
  • the screen material consists of a cylindrical screen, which makes it possible to produce in a very simple manner printings having the detail fineness and great detail sharpness as desired.
  • the invention further relates to a method for manufacturing a screen for printing consisting of a metal screen obtained by electrolytic deposition of at least one metal upon a screen skeleton characterized in that for producing a metal screen having a fineness of 250 to 1000 mesh a screen skeleton is used having a semi-circular cross-section and a flat bottom, and the bath solution passes through the openings in said screen skeleton from the bottom side thereof during at least part of said electrolytic depositing time, said skeleton being connected as the cathode.
  • Figure 1 shows a screen material 1 consisting of a metal screen 1 obtained by electrolytic deposition of at least one metal 2 upon a screen skeleton 3.
  • the screen has a fineness of 400 mesh, so that there are 400 openings 4 per 2,54 cm.
  • the electrolytic bath as used for depositing said metal is a well known electrolytic bath containing * an organic compound comprising at least one unsaturated bond which does not belong to a group such as butyne diol.
  • Figure 2 shows more particularly the shape of a number of openings in the screen. As seen, the free upper side 5 of the screen opening has a larger area than the area of the screen opening on the lower side of the screen 6.
  • the screen opening is defined by the curved walls 8 of the lands bounding the screen opening 4.
  • the metal deposited by electrolytic deposition mainly extends on one side of the screen skeleton. On the other side of the screen skeleton, only a small layer thickness 7 of the electrolytically deposited metal has precipitated. This is more particularly shown in Figure 2.
  • the shape of the screen openings is obtained by connecting a screen skeleton as the cathode and by having the electrolytic solution flow in the direction from the cathode to the anode or in the reverse direction.
  • the direction of flow is from the cathode to the anode.
  • the screen according to the invention is particularly well adapted for printings for which hitherto woven polyester gauze has been used.
  • the screen material according to the invention distinguishes itself very favorably from the woven polyester gauze by the dimensional stability of the screen material used, which results in the remaining screen material retaining its non- deformable character when forming the openings in the screen material, the screen permeability being no longer dependent upon the thickness of the lands of the screen material by properly selecting the walls of the screen openings, and, finally, the size of the screen openings being ensured at all times, also after an extended period of use, this being in contradistinction to applications using woven polyester gauze.
  • Figure 3 shows a cylindrical screen material according to the invention in the form of a cylindrical screen 1' said cylindrical screen material being particularly suitable for continuous printing.
