Definitions

  • the present invention relates to the filed of display panels or sheets and, in particular, discloses a method of creating panels suitable for impregnating images into.
  • Illuminated display panels find many uses in society especially where traders wish to advertise or market their products. For example, in fast food outlets, it is common to have a display panel advertising the types of food available. This can be in the form of a back illuminated panel which is partially transparent. The back illumination provides for an attractive end product. Further, sparkling panels often provide for atheistically pleasing products. The potential market for display panels is quite large especially where the panels can be made to provide an attractive display. Unfortunately, standard panels such as those formed of Perspex, PNC or polycarbonate have been unsuitable for impregnating images into. Recent products, such as DuPont's SentryGlas (Trade Mark) Expressions (Trade Mark) (Trade Mark) Expressions (Trade).

  • the method also includes the step of slowly cooling the substrate under compression so as to reduce any warping of the substrate due to thermal expansion.
  • the substrate can be formed substantially from acrylic, PNC or polycarbonate.

  • a substrate suitable for use for impregnating an image into comprising a acrylic, polycarbonate or PNC sheet that has been heated so as to substantially remove excess moisture in the substrate.
  • the substrate is cooled under compression so as to reduce any warping of the substrate due to thermal expansion.
  • the substrate is heated for at least 12 hours.
  • the substrate can be heated above substantially 180 Degrees Celsius.
  • a method of impregnating an image into a sheet comprising the steps of: (a) forming an image using ink on a first substrate; (b) heating the first substrate so as to reduce the water content of the ink on the first substrate; (c) heating the sheet; (d) pressing the first substrate against the sheet at an elevated temperature;
  • the method also preferably includes the step of cooling the substrate and sheet whilst they are preferably compressed together. Ideally, this includes maintaining a pressure on the surface of the sheet whilst cooling so as to reduce buckling of the sheet.

  • the manipulation of the gamut curve can be a trial and error process with the output image of a previous iteration being examined so as to determine gamut changes required so as to provide for a more linear gamut in the output display panel.
  • the manipulation of gamut curves will be readily understood by those skilled in the art of image creation and manipulation and the utilisation of image manipulation programs such as Adobe Photoshop TM.

  • it is ideally heated for 12 hours at 180 Degrees Celsius.
  • the time can be varied depending on equipment and materials utilised. Ideally, a number of samples should be tested using different drying regimes to determine best results.
  • the treated substrate and treated image are placed in contact and pressed together. This results in a fusing of the image into the acrylic substrate, hi one embodiment, an acrylic sheet and plotted image were pressed together in a Transmatic heat press at 200 - 225 Degrees Celsius for approximately 300 seconds at 3 bar or 40 PSI pressure.
  • the substrate and image are left to slowly cool in a compressed state.
  • This can be undertaken as illustrated in Fig. 3, wherein the substrate 30 is compressed between two layers of felt 31, 32 and further two layers of Malanite or other wood 34, 35. Weights can be placed on top of the Malanite sheet 34 so as to compress the overall arrangement 36.

  • the dehumidified substrate and dehumidified image are placed in contact and pressed together 46.
  • Four layers of cotton sheet were placed between the paper and the press, and a layer of coated paper was placed between the underside of the press and the membrane. This results in a fusing of the image into the membrane.
  • a PNB membrane and plotted image were pressed together in a Transmatic heat press at 155-160 Degrees Celsius for approximately 250-300 seconds at 700 hydraulic PSI.
