Definitions

  • the present invention relates to a composite sheet or ribbon, particularly for printing with thermal sublimation dyes.
  • Printing with thermal sublimation dyes is currently increasingly used to produce particular aesthetic effects on various products or to reproduce images on objects of various kinds.
  • the main problem of the transfer of said sublimating dyes from the backing to the object resides in the fact that said backing wraps with a certain difficulty and approximation when the objects printing whereof is to be performed have rather complex surfaces.
  • backings which are made of a paper-aluminum bonding, in which the paper is tissue-paper thin; due to its known plastic adaptability characteristics, said bonding allows to produce far better wrappings even on rather complex surfaces.
  • Offset printing requires a backing having good mechanical resistance to folding and dimensional stability, due to the several roller guides that are present in the machines that perform offset printing.
  • a principal aim of the present invention is to provide a sheet or ribbon having at the same time good mechanical resistance to folding, such as to allow offset printing with a cut-sheet printing machine, and a good ability to wrap even around objects having a complicated surface.
  • an object of the present invention is to provide a sheet or ribbon the production, printing, and application process whereof has times and costs that are competitive with respect to conventional processes.
  • Another object of the present invention is to provide a sheet or ribbon the cost whereof in terms of component materials is competitive with paper backings and bonded paper-aluminum backings.
  • Another object of the present invention is to provide a sheet or ribbon that can be produced with known technologies and entails no limitation as to the execution of high definitions and the formation of images.
  • Another object of the present invention is to provide a sheet or ribbon that can adapt to the most disparate fields of utilization, including in particular the eyewear industry, in which dye-sublimation printing can be applied.
  • a composite sheet or ribbon particularly for printing with thermal sublimation dyes, characterized in that it comprises a supporting layer onto which, at least on one side, a bonded paper-aluminum element is glued by means of an adhesive with the paper side facing outwards, said paper side being printed with sublimating dyes, the melting temperature of said adhesive being lower than the sublimation temperature of said sublimating dyes.
  • the bonded paper-aluminum parts are disconnected from the sheet or ribbon for thermal sublimation printing.
  • a composite sheet or ribbon particularly for offset lithography with thermal sublimation dyes, according to the invention, is generally designated by the reference numeral 10.
  • the sheet or ribbon 10 in this case, comprises a supporting layer 11 made of paper-like material of good consistency, such as card, on both faces whereof two bonded aluminum-paper elements 13 are respectively glued by means of a per se known adhesive, which has a melting temperature that is lower than the sublimation temperature of the dyes and is represented in the figures by two layers 12; the paper part of said bonded elements has the consistency of tissue paper, is directed outwards, and is printed with said thermal sublimation dyes.
  • a supporting layer 11 made of paper-like material of good consistency, such as card, on both faces whereof two bonded aluminum-paper elements 13 are respectively glued by means of a per se known adhesive, which has a melting temperature that is lower than the sublimation temperature of the dyes and is represented in the figures by two layers 12; the paper part of said bonded elements has the consistency of tissue paper, is directed outwards, and is printed with said thermal sublimation dyes.
  • paraffins and/or microcrystalline waxes as adhesives, both having a melting temperature that lies between 60 o and 90 o Celsius and is therefore distinctly lower than the sublimation temperature of the dyes, which usually ranges between 140 o and 220 o Celsius.
  • the method consists in: gluing, in this case at both faces of the supporting layer 11, by means of the adhesive 12, the corresponding bonded aluminum-paper elements 13, with the paper part facing outwards.
  • the composite sheet or ribbon 10 once assembled, is inserted in a per se known machine that performs offset or rotary offset printing, in which the thermal sublimation dyes are deposited on the paper part of the bonded element 13, first on one face and then on the other one.
  • the composite sheet or ribbon 10 is brought to the melting temperature of the adhesive and the supporting layer 11 is separated from both of the bonded aluminum-paper elements 13 by mechanical means.
  • the bonded aluminum-paper elements 13 thus released from the supporting layer 11 can be usefully used to wrap, by using the plastic adaptability characteristics of aluminum, the object onto which the dyes are to be sublimed.
  • the present invention has solved the above-described drawbacks of conventional products and processes; in particular, it should be noted that the composite sheet or ribbon can be offset printed, providing the maximum definition and image creation that is currently possible, without at the same time losing the plastic adaptability characteristics that are typical of the aluminum part of the bonded aluminum-paper element that is separated from the composite sheet or ribbon for use.
  • the adhesive which has a melting temperature that is lower than the sublimation temperature, in fact allows to associate, within the composite sheet or ribbon according to the invention, a part having a purely structural backing function and another part with functions that are purely dedicated to printing and wrapping.
  • composite sheet or ribbon according to the invention does not affect a possible continuous process in any way.
  • the dimensions as well as the materials may be any according to the requirements.
