Definitions

  • the present invention relates to methods of producing simulated opals, such as opal doublets, black opals and decorative articles resembling opals as, or as part of, an article, and so as to exhibit a display of spectral colours resembling opals, opal doublets or black opals.
  • Opal doublets are made from thin slices of opal usually blackened on the back to enhance the colour and then adhered to a rigid layer of potch, glass, quartz, obsidian or other suitable material compatible with the opal so that when the opal is adhered to the backing material it does not crack or craze with expansion or contraction due to changes in temperature.
  • Opal is also brittle and therefore it poses a problem to inexperienced jewellers. The heat created when polishing a piece of jewellery may be sufficient to cause the opal to crack. The jewellers, therefore, face a loss of revenue due to breakages.
  • the article comprises of two random patterned orthogonally engraved interactive holograms or diffraction gratings double embossed or superimposed over each other in such a manner that both patterns are clearly visible at similar intensity and interact to give a three dimensional effect which resembles an opal.
  • the surface reproduction of an opal is overlayed onto holograms or diffraction gratings created by methods known as SPECIAL HOLOGRAPHIC EFFECTS to be later described and so arranged that the effect created by overlaying or overprinting the surface reproduction of an opal onto the INTERACTIVE holograms or diffraction gratings creates an article which stimulates an opal, opal doublet or a black opal.
  • a layer or layers of iridescent materials may be overlayed or interposed between other layers to create interference layers within the article.
  • the method of the invention may be used in a variety of ways thus allowing it to be applied to, or used in or on, a wide variety of products to give them a decorative opal effect.
  • the present invention provides an opal simulation comprising of a two dimensional surface reproduction of the surface of an opal applied to the surface of a hologram thus producing a simulated opal effect for use on a range of products which resemble, and have the play of spectral colour of, genuine opal.
  • the material may, therefore, be made in large sheet form from which sections are cut or formed to any shape or size.
  • One aspect of the present invention it's flexibility, allows it to be applied to uneven or contoured surfaces or to be wrapped around a surface or to be formed into a three dimensional shape, such as a box, for packaging, thereby allowing the fashion designer more scope for use of the product.
  • simulated opal doublets may be mass produced at low cost by overlaying a hologram with opal colours, patterns and textures reproduced from genuine opals or applying the image by a variety of methods to a holographic material. Simulated opal doublets are by far the least expensive to manufacture but still exhibit the play of colour which has the essential visual impact of the genuine opal for application in the various industries where genuine opal cannot be used but to which the present invention may be applied. Like genuine opal doublets the opals of the invention display a surface of spectral colours which change as the opal is moved or rotated.

  • a hologram or diffraction grating is constituted by, in accordance with the invention, a pair of randomly patterned orthogonally embossed holograms or diffraction gratings.
  • Reproductions of the surface of an opal are obtained by the various methods described hereafter.
  • Opals are cut into thin slices and placed on a black background immersed in a fluid having a suitable refractive index to enhance the play of colour, and photographed, in order to make a surface reproduction of the opal colours, patterns and textures.
  • the reproduction may be made by photographing the slice in the fluid or by blackening the back of the slice and placing the slice face down on a colour laser photocopiers with a suitably refractive fluid between the opal slice and the glass copying surface of the copier.
  • the reproduced image of an opal, reproduction of the surface of an opal or the actual surface of an opal may be scanned directly into a computer, where an array of stored images of the colours, patterns and texture of various opals may be combined, using graphics programmes, into large random patterns allowing for generation of a wide variety of simulated opal effects on a single sheet but, by using the programmes, it also allows for the patterns to be randomly changed so that no two opal simulations are identical.
  • the opal images may be in the form of photographs, prints, paintings or photocopies of opal colours, patterns and textures.
  • an opal doublet may be made and then a surface reproduction be produced by one of the aforementioned methods, thereby making a simulation of the actual doublet. It is preferable that the opal backing be black in order to intensify the colours of the opal.
  • opal surface images Once a selection of opal surface images have been stored it is only necessary to reproduce other opal surface images if new opal features are discovered.
  • desired pattern When the desired pattern has been selected it is then applied by a variety of methods to the surface of a suitable hologram or diffraction grating or transferred onto a suitable transparent material, such as plastic film, plastic sheet or glass after which a specific holographic material is adhered to the image side of the substrate for protection of the image.
  • the assembly may be cut to any shape or size for use in jewellery or other products.
  • the layer of transparent material bearing the image may be laminated on the toner or printed side with a sheet of transparent material, or laminated between two sheets of transparent material, for further protection of the image and also to further protect the surface of the finished product (the toner surface of a transparency generated from a colour laser copier contains a silicon oil which must be removed prior to lamination) .
  • the lamination of this layer also creates a more rigid laminate.
  • holograms which had a random pattern with a vivid spectral effect.
  • Holograms and diffraction gratings are usually based on a geometric format for ease of manufacture. Since the play of colour in opal is not visibly geometric these types of holograms are less suitable. This is not to say that they cannot be used but the random pattern or a rolling play of spectral colour is more realistic.
  • the surface of a simulated opal doublet is usually flat or slightly domed according to the variety of opal used in the manufacture of the simulated opal doublet.
  • the simulated opal doublets for jewellery use may be made with a flat surface or with a protective coating of thermosetting resin, or with a preformed plastic cap, but when used on a stationery product the opal image may either be flat or formed into a low dome to give the appearance of a solid opal.
  • the opal images may be generated in a variety of ways as listed below.
  • the image is generated directly from a computer onto a suitable transparent material using a computer system linked to, for example, a colour laser copier;
  • the image may be generated or copied onto a material which allows for the transfer of the image onto another surface such as plastic, glass, quartz or similar transparent
  • the image may be photographed onto a transparency which becomes the coloured, textured layer used in the production of the doublet and is then overlayed or adhered to the holographic layer; .
  • the image may be printed onto a suitable flat surface made of plastic, glass, quartz or other similar transparent material; 5.
  • the opal pattern may be printed directly onto a suitable holographic surface;

  • the image may be painted onto a suitable surface such as a transparent film or painted directly onto the hologram; 9.
  • the image may be a photographic slide or an emulsion, similar to that used in making slides, may be coated onto a sheet of plastic or glass and the surface is then exposed to the image of the desired opal pattem.
  • Colour images can be applied directly onto holograms or diffraction gratings but it has not been previously contemplated to create a simulated opal doublet or a simulated opal product using the methods described herein.
  • the present invention allows for the creation with in the industry for more effective display and promotional material, packaging materials as well as souvenir and gift products where a simulated opal effect would have greater visual impact than the current designs.
  • the method of manufacture in accordance with the present invention requires the surface reproduction of an opal to be generated onto a sheet of clear plastic film and a double sided optically clear transfer tape is laminated to the toner, or emulsion, surface of the transparency, the protective coating is peeled away and a hologram or diffraction grating is then adhered. A rigid backing member is then adhered to the back of the hologram to form a complete assembly from which simulated opal doublets may then be cut into the desired shape or size.
  • an adhesive layer may be applied to the rear of the rigid surface of the assembly with a protective coating of release paper. The release paper being removed when it is necessary to adhere the simulated gem to another surface or product.
  • the rigid layer and adhesive backing layer are replaced by a magnetic material. It is possible, using this process, to generate opal doublet simulations in many and varied shapes using simple computer software to mix patterns and textures in order that, like genuine opal, each simulated opal doublet is slightly different. It is also possible to make mosaic patterns or simulated intarsias by combining a variety of images or to incorporate an initial, logo, or other featured image, upon the surface of the opal pattern. This is created by using computer graphics, hot foil stamping or by overprinting onto the opal image.
  • the rigid backing method of production is desirable for jewellery applications it will be necessary, in some applications of the method, to print a reproduction of the surface of an opal directly onto the holographic material, with or without an adhesive backing.
  • the advantage of this being for use on large objects or objects with an uneven surface. Whilst this will not give the unlimited patterns, textures, and colours, possible with computer generated images it provides a much less expensive means of manufacture and allows the methods of the invention to be used in, or on, a far greater range of products.
  • By printing the opal patterns onto a holographic surface there is a huge saving in labour and materials.
  • the resulting image may then be cut to any shape or size to suit a jewellery setting or other product as required. Because the material is flexible the simulations may be wrapped around a product overcoming the limitations f rigid varieties produce by the methods of the invention.
  • a rigid backing may also be adhered in certain uses of the product such as place mats where the surface of the print is also protected by a layer of durable transparent material.
  • the hologram may be embossed or hot stamped onto a sheet of material and then overprinted with the opal pattern.
  • An image of a person, place, scene or object, or the like may first be printed onto a suitable surface and then a hologram embossed or hot stamped onto the print.
  • the holographic area of the surface of the printed object is then overprinted with an opal reproduction.
  • embossing a hologram onto a product for example a stationery product, it may only be necessary for a section of the product to be embossed with the hologram.
  • the hologram becomes a simulated opal within a picture.
  • This picture may be an opal mining scene with the simulated opal depicting a seam of opal running through a rock, piece of rough opal being held by a miner or, in another case, the picture or graphic rendition may be of a person wearing an opal.
  • the opal portion being the embossed hologram overprinted with opal patterns to simulate an opal whilst the rest of the picture is normal graphic printing without the holographic effect and being printed by any suitable printing, hot stamping, painting, photographic or other technique for laying down graphic images.
  • the holographic pattern may also be embossed onto metallised paper or tapes and then overprinted with an opal pattern for use on products such as wall paper, adhesive tapes, labels, posters, point of sales promotional materials, signs, wrapping paper or decorative opal effect packaging.
  • the method of the present invention may also be applied to a variety of surfaces such as post cards, envelopes, business cards, packaging, letterheads, wrapping materials, badges, pens, pencils, salt and pepper shakers, spoon and cutlery handles, plates, cups, table tops, watches, clocks or any surface where the product would be enhanced by an opal simulated effect as opposed to the usual holographic graphics presently in vogue.

  • SPECIAL HOLOGRAPHIC EFFECTS The holograms used in the manufacturing methods of the present invention are new in that they involve the process of embossing one holographic pattem over the top of another holographic pattem. A semi metallised hologram may be used to reduce the metal effect which may also be double embossed.
  • holograms are suitable for this purpose so the method of the present invention enables the production of a hologram which is used to create a realistic opal effect when overprinted with opal patterns, colours or textures.
  • Most of the holograms readily available are made on a geometric pattern and they are not realistic to the discerning eye.
  • the other problem with normal holograms is the metallic appearance of the hologram itself, because of the material upon which it is embossed. To overcome this problem we have used a technique of double embossing one holographic pattem over the top of another pattern.
  • the random effect of the hologram is created by rotating the image in increments of 10 degrees through 90 degrees as the master plate is exposed for each section of the pattern and then turning the image through 90 degrees and re-exposing the master plate thereby creating an orthogonal embossing which results in a display of spectra colours when the image is moved at right angles as opposed to normal holograms which are only visible when viewed at one specific angle.
  • the new technique displays colour at various angles when the hologram is rotated through variou degrees of rotation. This is an advantage over current holograms, and combined with the double embossing technique, a more effective holographic opal effect is thereby created.
  • a further method is to use a semi-metallisation technique which does not give such a vivid metal reflection, or mirroring, from the surface of the holographic material.
  • the hologram may be transparent to translucent whilst still reflecting spectral colours. Als the more information that is embossed onto the material th less the metallic reflection.
