  • the invention relates to a method of so applying a design, particularly a multi-colour design, to leather or synthetic leather, and to leather and synthetic leather products produced by the method.
  • the invention relates also to a decorative device or decorative article and to a method of manufacturing such a decorative device or article.
  • the invention relates to a decorative article of the nature of a wall hanging, and to a method of manufacturing such a wall hanging.
  • the invention relates to a method of decorating an article or object, such as a garment, or an accessory of apparel such as a hat or handbag, or a domestic accessory or ornament such as a lampshade, bookjacket, cushion, or the like by applying to such an article or object a decorative device according to the invention, and to articles and objects so decorated.
  • the invention relates to articles or objects, such as items of furniture, or accessories such as handbags, shoes, bookjackets, wallets, purses, and the like, which are made of or covered with leather or synthetic leather decorated by the method of the invention.
  • a method of applying a design by a printing process to an expanse of material which is dimensionally unstable, in particular a material selected from the group comprised of genuine tanned leather and synthetic leather which method includes the steps of applying the expanse of material to a rigid backing plate to define a pictorial area where the material adheres to the backing plate; providing key means on a print table of a stencil or screen printing apparatus, the key means being adjustable to demarcate a predetermined position on the print table for the backing plate where a print plate of the printing apparatus will produce a printed image in a desired location on the pictorial area; positioning the backing plate on the print table in the demarcated predetermined position with reference to the key means; and printing a printed image in the desired locality on the pictorial area by means of the print plate.
  • a method of applying a design to a pictorial area provided on an expanse of material which is dimensionally unstable, in particular a material selected from the group comprised of genuine tanned leather and synthetic leather, by a printing process which method includes the steps of providing an expanse of selected material which is dimensionally unstable and which has a surface to receive a design by a printing process; applying the expanse of selected material to a rigid backing plate so that a pictorial area is defined where the selected material adheres to the backing plate; providing a print plate selected from stencil-print plates and screen-print plates on which an image of the desired design is applied, the print plate being arranged to produce a printed image of the design in a predetermined position relative to a print table; providing a print table on which the rigid backing plate carrying the expanse of selected material may be supported in the predetermined position for the pictorial area to receive the printed image in a desired location by means of the print plate; providing key means on the backing plate to register with corresponding adjustable key means
  • the pictorial area may be provided on an expanse of synthetic leather, the synthetic leather being selected to present as smooth as possible a surface to be printed on. It should be understood, however, that even where a synthetic leather has been selected to have such as smooth a surface as possible, the surface would usually still have small irregularities which may make it difficult to achieve a clear printed image thereon, with sharp and well-defined edges and an even colour distribution.
  • the expanse of synthetic leather may have irregularly shaped or formed edges, so as to resemble for example an animal skin.
  • the pictorial area may be provided on an expanse of genuine tanned leather, the surface of which has preferably been rendered as smooth as possible, ie substantially untextured, to receive a design by way of a printing process.
  • genuine tanned leather the surface of which has preferably been rendered as smooth as possible, ie substantially untextured, to receive a design by way of a printing process.
  • the leather would usually still have small irregularities (ie a natural grain), which may make it difficult to achieve a printed image thereon with sharp and clear outlines and an even and true colour tone.
  • both suitably prepared genuine leather and selected synthetic leather may be used in accordance with the invention, and the term "leather" when used in the specification should be interpreted accordingly.
  • the design applied to the pictorial area may be of any suitable or desired nature, for example a design portraying animals, birds, trees, flowers or any wild life theme, or ethnic figures, or a geometric or abstract design or the like, and the design is applied to the pictorial area by a printing process.
  • the design may comprise a logo, a company or family crest, a trade or sports emblem, or the like, again applied to the pictorial area by a printing process.
  • the method of the invention as will be described in more detail below, has been found to give particularly good results when used for the printing of a multi-colour design on a dimensionally unstable, stretchable material such as leather, including genuine and synthetic leather, and it makes possible the printing of high quality multi-colour designs on leather and synthetic leather, which previously could not be done.
  • a method of applying a multi-colour design to a pictorial area provided on an expanse of leather, including genuine and synthetic leather which includes the further steps of providing a plurality of colour-separated print plates selected from stencil-print plates and screen-print plates, representing colour-separated images of the desired design so that superimposed images printed by the plates together will provide a desired multi-colour design; providing on the different print plates different printing inks of the desired colours to correspond with the colour-separated print plates and of a consistency to permit the ink to adhere to the surface of the material of the pictorial area; consecutively adjusting the key marks on the print table to demarcate a plurality of predetermined positions for the backing plate with reference to the plurality of print plates, so that a colour-separated image will be printed in a desired locality on the pictorial area; consecutively positioning the backing plate carrying the expanse of material in the different predetermined positions with reference to the key means; consecutively printing colour-separated
  • the Applicant has found that this difficulty may at least partially be overcome if the expanse of synthetic or genuine leather or other stretchable fabric, which is to form the pictorial area, is first applied to a rigid backing plate and is allowed to remain on the plate during the entire printing process. Accordingly, the expanse of synthetic or genie leather is prepared for printing by removably applying it, preferably with the aid of a pressure sensitive adhesive, to a rigid backing plate.
  • the backing plate may be a metal plate or a plate of a synthetic plastics material, eg acrylonitrile butadiene styrene (ABS).
  • the backing plate may be coated with a pressure sensitive adhesive, eg a conventional textile adhesive, to provide a tacky surface to which the expanse of synthetic or genuine leather may be applied.
  • a pressure sensitive adhesive eg a conventional textile adhesive
  • the provision of key means on the print table and on the backing plate provides assistance in this regard, that the pictorial area can be positioned and held accurately and statically in register with the print plate, in order to obtain a clear and sharply defined print of the right colouration.
  • the backing plate bearing the pictorial area may thus be placed on a printing table with reference to the key means on the printing table, and so that the key means on the backing plate are in register with those on the print table. Thereupon the consecutive printing runs may be carried out, substantially in the conventional manner, to print the design in the consecutive separated colours so as to obtain the final multi-colour printed product. Once the printing ink has dried, the expanse of material bearing the completed printed design is poled from the backing plate.
  • the backing plate which retains its tacky surface, is reusable with the next expanse of material to be printed.
  • the pressure sensitive may thus preferably be selected to retain its tacky surface for several consecutive runs.
  • the pressure sensitive adhesive is further preferably selected so as to contain no ingredients which would seep through the leather to adversely affect the printing or the printing inks, or the printed image once applied.
  • a plurality of prepared backing plates may be positioned and printed consecutively, with a design which will be applied on each in a predetermined accurately positioned locality.
  • the invention accordingly provides a method of applying to a pictorial area a multi-colour design of enhanced accuracy and colour registration, which includes the further steps of placing a removable transparent overlay sheet over the pictorial area prior to printing an image thereon; printing a primary image onto the transparent overlay sheet; adjusting the key means with reference to the position of the primary image on the transparent overlay; adjusting the position of the backing plate carrying the expanse of material with reference to the key means; removing the transparent overlay sheet; printing a colour image onto the pictorial area; and repeating the foregoing steps using a transparent overlay sheet for a primary image prior to a colour image on the pictorial area in respect of each subsequent colour run.
  • a transparent overlay sheet also enables a multi-colour design to the applied to a plurality of consecutive pictorial areas provided upon a plurality of backing plates, with improved results as to colour registry, definition and colour toning.
  • the invention thus provided a method for applying a multi-colour design to a plurality of consecutive pictorial areas provided on a plurality of prepared backing plates, which includes the further steps of providing a plurality of rigid backing plates each with an expanse of material, preferably selected from the group comprised of genuine tanned leather and synthetic leather, applied thereto; providing a plurality of colour-separated print plates on which colour-separated images of the design are applied; positioning a first prepared backing plate on a print table and placing a transparent overlay sheet over the pictorial area; printing a primary image with a first colour-separated print plate on the overlay sheet; if necessary adjusting the position of the key means on the print table and the position of the first backing plate, with reference to the position of the primary image on the overlay sheet; removing the overlay sheet and printing a final image with the first colour-separated print plate on the pictorial area of the first backing plate; removing the backing plate from the print table and allowing the ink to dry; positioning a second
  • the transparent overlay sheet may be a sheet of a transparent synthetic resin or celluloid with substantial rigidity and a smooth surface from which applied printing inks may readily be removed.
  • the overlay sheet should preferably be inert to the printing ink.
  • an ink of dark colour is used for printing the primary image on the transparent overlay sheet, so that the outlines may be observed clearly, so as to enable accurate adjustment of the key means on the print table and of the position of the backing plates may be achieved.
  • the transparent overlay is positioned over the first prepared print plate and a first primary print executed.
  • the position of the key means is adjusted.
  • the primary trial print may also be in the colour-separated colour tone, so that the colour tone of the ink may be adjusted, with reference to the primary trial print.
  • a plurality of images in the correct colour and in the correct position may be printed consecutively.
  • the pictorial area first with a white or other selected neutral colour background, preferably having the silhouette outlines of the desired final pictorial design.
  • the pictorial design may then be printed onto the white or neutral background by way of consecutive colour runs, as explained above.
  • the Applicant has found that it is particularly advantageous to use a screen-printing process in the method according to the invention.
  • the material, eg silk, of the screen-print plate may itself stretch slightly during the printing procedure, ie when a conventional rubber squeegee is moved across the screen plate, thereby slightly displacing the printed image, this slight displacement is reflected on the transparent overlay sheet.
  • the key means and the corresponding position of the backing plate may be adjusted with reference to the displaced image on the transparent overlay sheet, to compensate for the stretching of the silk screen.
  • care should be taken that a uniform directional orientation of the colour-separated images is maintained. Because the silk screen will stretch in the direction in which the squeezee operates, it is important that the different colour-separated images all be orientated so that the stretching will occur in the same direction for each one.
  • the adjustable key means provided on the print table may conveniently include a base plate which may be positioned on the print table in a selected position determined with reference to a print plate, to permit an image printed by the print plate to be printed in a desired locality on the base plate.
  • the base plate may be secured to the print table in the selected position, eg by means of adhesive strips.
  • the base plate may carry one or more keying pins, indicating a predetermined position on the base plate in which a backing plate may be mounted with the aid of corresponding keying apertures provided in the backing plate.
  • the base plate may thus be positioned and secured on the print table in a position selected with reference to the position of an image printed by a print plate, and a backing plate may in turn be placed in a predetermined position on the base plate with the aid of the corresponding keying pins and apertures provided on the base plate and backing plate respectively.
  • a transparent overlay sheet is used, as described above, on which a primary trial image can be printed, the position of the base plate is determined with reference to the position of the primary trial image.
  • the Applicant has found conventional matt or no-gloss printing inks to provide a good adherence to the leather surface, but that an adjustment in the colour toning has to be made in order to obtain the desired colour shade on the leather material.
  • the printing inks once applied to the leather surface, do not display exactly the same colour shade as prior to application.
  • the printing inks used should thus be selected to provide good adherence to the leather surface to which the design is applied, and to produce a pliable product, and furthermore the colour toning may have to be adjusted.
  • Inks with a matt finish are preferred, since the glossy inks often contain a varnish which may cause cracking of the printed design when the leather article is handled.
  • the ink should further be rendered to a consistency to pass freely through the screen-print plates without clogging the screen, but should not be so runny as to smudge on the leather surface.
  • the ink should also not dry too quickly; it should preferably penetrate into the surface layers of the leather material.
  • the drying of the ink of the printed image applied to the pictorial area may be accelerated or enhanced to speed up the overall printing process. Accelerated drying may be achieved by directing an air flow over the printed surface, or preferably by moving an entire backing plate with the expanse of leather applied thereto, through a drying tunnel with one or more batteries of infrared lamps, preferably provided in combination with air flow means, to accelerate the drying of the printed ink.
  • the printed products may conveniently be conveyed through the drying tunnel on a conveyor belt; the infrared lamps may be provided in batteries above the conveyor belt; and an air extraction fan may be provided to provide with air flow through the tunnel.
  • a clear protective or fixative coating may be applied over the pictorial design, or if desired over the entire pictorial area, to protect the printed design.
  • the protective layer which serves as a fixative, should preferably be pliable and resistant to water and conventional organic solvents and cleaners.
  • a decorative device or article which includes a pictorial area provided on an expanse of a material selected from the group comprised of genuine tanned leather and synthetic leather with a surface suitable for the application of a design by a printing process, the pictorial area bearing a design applied thereon by a printing process and with the use of printing ink, by a method according to the invention.
  • the design may preferably be a multi-colour pictorial design.
  • the decorative device may have a decorative surround extending at least partially around the pictorial area and made up of randomly shaped and positioned pieces of material selected from the group comprised of genuine tanned leather and synthetic leather, optionally in combination with other materials selected from the group comprising cloth including woven, non-woven and knitted fabric, feathers, beads, fur, plant material and stones.
  • the design applied to the pictorial area may be enhanced or extended by the addition of related items or materials, such as feathers, seeds, grass, pieces of wood or bark, fur, beads (particularly of wood or clay), stones (particularly semi-precious stones), etc.
  • the expanse of leather may be mounted onto a backing layer which may preferably be pliant, eg of canvas. Such a backing layer does not only provide reinforcement, but also provides a neatly finished-off appearance. Furthermore, the materials forming the surround may also partly be applied onto the backing material.
  • the expanse of leather may be applied to the backing layer by bonding with a suitable adhesive. Before applying the expanse of leather material to the backing layer, the rear side of the leather may preferably be coated with a protective layer to prevent solvent or other harmful components of the adhesive from seeping through the leather and discolouring or dislodging or otherwise affecting the printed design.
  • a decorative surround may be provided, which may be made up of irregularly shaped pieces of genuine or synthetic leather, which may be applied, such as by means of adhesive, to extend in a random arrangement partially or wholly around the expanse of material bearing the pictorial design.

  • the decorative device may instead be applied to another object or article, such as a garment, or an accessory of apparel such as a hat or handbag or a domestic accessory such as a lampshade or cushion, etc so as to decorate the object or article.
  • the decorative device may thus be of dimensions selected in accordance with the object or article to be decorated. For example, if it is intended to decorate a garment such as a T-shirt, shirt or blouse, the decorative device may be of such dimensions as to permit the device to be applied to the front of the T-shirt, shirt or blouse.
