Definitions

  • the present invention regards a process for making transferrable decorations and a transferrable decoration in particular obtained by means of said process.
  • the process and the transferrable decoration, object of the present invention are inserted in the field of production for making decorations to be transferred, preferably under cold conditions, onto surfaces of any kind - both smooth and rough (such as wood, glass, metal, plastic, plaster, etc.) - for internal and external settings, and in particular also on wall surfaces, e.g. on walls and ceilings of building rooms, building facades, on fencing walls, etc.
  • the present invention allows making, by means of the use of digital printers, transferrable decorations having pre-spaced graphic elements.
  • printable media for making decorations on surfaces e.g. of panels, windows, wall surfaces have been known on the market, which allow transferring onto a surface to be decorated an image that was previously printed or painted thereon.
  • Such printable media for example comprise a first support layer constituted by a paper sheet, a second water-repellent resin layer placed to cover the first support layer, and a transparent film on which the decoration to be transferred is made.
  • a first support layer constituted by a paper sheet
  • a second water-repellent resin layer placed to cover the first support layer
  • a transparent film on which the decoration to be transferred is made.
  • glue a continuous layer of glue on the printed face of the transparent film and to attach the latter to the surface itself.
  • the paper sheet of the first layer is removed in order to uncover the transparent film on which the decoration is printed.
  • pre-spaced adhesives which comprise multiple adhesive elements, each for example depicting a letter, intended to be attached to the surface to be decorated; such elements are separated from each other so as to form a decoration (for example comprising a word), in which the interspace between the different letters is not covered with transparent film.
  • the achievement of decorations with pre-spaced graphic elements provides for arranging an adhesive paper provided with a siliconized paper support sheet, on which an adhesive film is attached.
  • a step is provided for printing the decoration, in which a printer is employed for making - on the film of the adhesive paper - an illustration provided with multiple separate graphic elements (e.g. the letters of an inscription or a line drawing coming from vector rows).
  • a printer is employed for making - on the film of the adhesive paper - an illustration provided with multiple separate graphic elements (e.g. the letters of an inscription or a line drawing coming from vector rows).
  • a cutting step in which the film of the adhesive paper is cut out along the borders of the single graphic elements of the illustration, by means of for example a cutting plotter.
  • a step is provided for removing the film scraps between each graphic element, such that only the parts of the film containing graphic elements to be applied to the surface to be decorated are left on the adhesive paper.
  • Such scrap removal step is normally executed manually.
  • a step is provided for applying a further adhesive film (termed “application tape” in the field jargon) which, during application of the decoration to the surface to be decorated, has the function of transporting the graphic elements from the adhesive paper to the surface to be decorated itself.
  • application tape in the field jargon
  • the support sheet of the adhesive paper is removed and the application tape is pressed against the surface to be decorated (such as the window of a store) in order to attach to such surface the parts of the adhesive film that contain the graphic elements. Subsequently the application tape is removed, uncovering the cut-out graphic elements that form the decoration.
  • a first drawback of the pre-spaced adhesives of known type briefly described above is due to the fact that long times are required for the achievement thereof, since it is necessary to print the decoration on adhesive paper, bring it to the cutting plotter in order to execute the cutting step, manually execute the scrap removal step and apply the application tape.
  • a further drawback of the pre-spaced adhesives of known type is due to the fact that they are not adapted to be applied on rough or course surfaces (such as wall plaster, wood, rough drywall) or to surfaces subjected to heat sources such as spotlights, since the film parts of the single pre-spaced graphic elements (in particular if of small size) tend to not stably adhere to the surface to be decorated, for example being detached even already from the time of removal of the application tape.
  • the patent application EP 0209544 describes a transferrable decoration of known type which comprises a transparent sheet-like medium on which a first glue layer is deposited, and on such first glue layer an ink layer for making a graphic element is in turn printed.
  • the transferrable decoration also comprises a second glue layer sensitive to actinic rays deposited above the ink of the graphic element. It is provided to apply actinic rays to the decoration in order to neutralize the zones of the second glue layer that are extended outside the graphic element. In this manner, when the sheet-like medium is removed from the wall to which the decoration is applied, the aforesaid neutralized zones of the second glue layer are removed, leaving attached to the wall the parts of such second glue layer below the ink of the graphic element.
  • the patent application EP 0241212 describes a further transferrable decoration of known type which comprises a carrier sheet on which a first adhesive layer is deposited, and on the latter an ink is printed.
  • the transferrable decoration also comprises a second adhesive layer that has different zones (outside and inside the ink) which have different bonded forces in order to maintain the ink attached to a substrate on which the decoration is intended to be applied.
  • the main object of the present invention is therefore to eliminate the abovementioned drawbacks of the solutions of known type, by providing a process for making transferrable decorations and a transferrable decoration which allow applying, in a simple and quick manner, decorations with pre-spaced graphic elements on surfaces to be decorated.
  • Further object of the present invention is to provide a process for making transferrable decorations that is simple and quick to actuate, in particular without having to employ cutting plotters nor execute scrap removal operations.
  • Further object of the present invention is to provide a process for making transferrable decorations capable of being applied on any type of surface, in particular even on rough, irregular or porous surfaces, ensuring an optimal adhesion of the decorations to the surface.
  • Further object of the present invention is to provide a process for making transferrable decorations which allow making decorations that are resistant over time.
  • Further object of the present invention is to provide a process for making transferrable decorations which allow attaining decorations of particularly thin thickness, and in particular which do not have reliefs from the decorated surface that are substantially visible to the naked eye.
  • Further object of the present invention is to provide a process for making transferrable decorations which allow simply and quickly transferring the graphic elements onto the surface to be decorated, in particular under cold conditions (i.e. without having to warm the surface to be decorated or the printable decoration itself) and under dry conditions (i.e. without having to wet or moisten the transferrable decoration with water or with aqueous solutions).
  • Further object of the present invention is to provide a transferrable decoration that is simple and inexpensive to produce.
  • the process for producing transferrable decorations allows making graphical decorations to be transferred, preferably under cold conditions, onto surfaces of any kind, smooth or rough (such as wood, glass, metal, plastic, plaster etc.), both for internal and external settings, and in particular also on wall surfaces, e.g. on walls and ceilings of building rooms, building facades, on fencing walls, etc.
  • the present process allows attaining pre-spaced transferrable decorations, which comprise in particular multiple graphic elements (such as letters, words, signs, images, drawings, etc.) that are separated from each other, and are intended to be applied on the surface to be decorated with such cut-out graphic elements.
  • the present process for making a transferrable decoration 1, comprises a step for arranging a flexible sheet-like medium 2, provided with a first face 3 and preferably provided with a second face 4 directed in opposite sense with respect to the first face 3 itself.
  • the sheet-like medium 2 (or transfer medium) comprises a support sheet 5, in particular made of polyester, and a water-repellent material layer 6 deposited on the support sheet 5 and adapted to define the aforesaid first face 3 of the sheet-like medium 2.

  • the ink layer 9 is deposited by the printer on the water-repellent material layer 6 which defines the first face 3 of the sheet-like medium 2.
  • the water-repellent material layer 6 suitably accepts the ink layer 9 deposited thereon in the printing step, ensuring a suitable adhesion of the ink in order to precisely obtain in particular the border 7' of the graphic element 7, and simultaneously ensuring the correct separation of the ink layer 9 from the sheet-like medium 2 when the transferrable decoration 1 is applied to the surface to be decorated, in order to leave the graphic element 7 attached to the surface itself, as described in detail hereinbelow.
  • the printer deposits two or more ink layers 9 superimposed on the same print area 10, for example in order to make the graphic element 7 more covering.
  • the latter is printed on the first face 3 of the sheet-like medium 2 in a mirrored manner, in particular it being intended that the graphic element 7 is reproduced on the first face 3 in a mirrored manner with respect to the orientation of the decoration when it is applied to the surface to be decorated.
