Definitions

  • the present invention relates to the field of printing and marking, for decorative or informative purposes, of objects or articles, structure continuous or not and with flat surface or not.
  • the invention relates more particularly to a method and a color (multi-color) marking or printing device transparent or opaque supports, in particular made of polymer material.
  • the markings reported by so-called inkjet or pad techniques are not generally not permanent due to the non-porous nature and chemical incompatibility of polymer surfaces.
  • polyolefins have the reputation of being difficult to mark without a prior preparation of their surfaces.
  • the resistance of markings for example to scratches or solvents is limited to the point that it is necessary to deposit a protective layer on the marking carried out.
  • Laser marking is a technology which to date is commonly used. It presents itself as an alternative solution at cost reduced and environmentally friendly. The performances are very satisfactory both in terms of processing speed and quality of markings.
  • Laser marking is a process which makes it possible to carry out on suitable supports for permanent and scratch-resistant markings without the use of solvents and without prior surface preparation. The markings cannot be removed or deleted without damaging the support.
  • Marking by ultraviolet process requires ink which reacts to light of an ultraviolet wavelength at around 350 nanometers.
  • the fixing of this special ink called “ink polymer” is produced on the surface of the material by a crosslinking step.
  • Cross-linking is a phenomenon of ink polymerization which product on the surface of the marked product. There is no migration of color pigments in the material and therefore the marking is less resistant and less durable.
  • a particular range of items or parts to be marked is made up of textiles, a wide variety of fabrics being made of thermoplastic material (polyamide, polyester).
  • the present invention aims to overcome the main limitations and to overcome the essential disadvantages set out above.
  • the invention also relates to a device for setting work of the aforementioned method, characterized in that it comprises, on the one hand, directed means of projection of liquid coloring substances, supplied each with a specific substance, and adapted to be moved above of the surface of a support to be marked or printed, said support being fixed or mobile, on the other hand, means of generation and application at least one infrared laser beam, continuous or not, directed towards the surface of the support so as to follow permanently and in real time the or the mobile deposit area (s) of the projection means directed or to be followed posteriorly the line (s) defined previously on the surface of the support by directed projections of coloring substances and, finally, means of command and control of the projection means, of the means generation and application of laser beam (s) and, optionally, means for moving the support (1), the beam (s) emitted by the generation and application means with suitable power to fix the coloring agents of the different substances liquid dyes with the support material.
  • a structure coloring adapted to the nature of the support and compatible with the length wave from the laser source is deposited on the surface of the substrate.
  • a infrared laser radiation irradiates the coloring agent by inducing after its passage a solid bond with the substrate without significant alteration support, but causing at least partial migration of color pigments in the material.
  • the spray deposition of the substances liquid dyes 2 can be produced using directional nozzles 3, for example mounted in a print head 3 'operating according to the principle known as inkjet (technique known to those skilled in the art) and moving relatively above the surface 1 'of the support 1 to to mark.
  • inkjet inkjet
  • the print head 3 ' can be provided movable above a support 1 fixed or fixed above a mobile support 1 (marking with fly).
  • the nature and composition of the coloring substances may be diverse.
  • water-based dyes of the conventional jet ink type ink, textile industry inks and dispersed inks.
  • pigments organic can be of the coated type, their coating (for example in TPLE or TPLD) dissolving and serving as a binder with the material of the support, the solvent having to be compatible with the latter.
  • Oil-based inks can also be used.
  • the liquid coloring substances 2 sprayed consist of mixtures of a liquid coloring agent, for example under form of ink or powder in suspension, compatible with the material of the surface 1 'of the support 1, and of a radiation absorbing agent infrared, able to transform at least part of the photonic energy received by the coloring substances 2 deposited on the surface 1 'of the support 1 in heat.
  • Fillers in the form of absorbing agents used possibly depend on the solution present in the substances dyes 2.
  • the fillers used may be of the type currently known under the designation S169900 / 2 and manufactured by the company AVECIA, these charges being soluble in water.
  • absorbent agents developed and manufactured by the company AVECIA under the name 925 NP.
  • Treatment with the laser beam 4 of coloring substances 2 deposited on the support 1 can be done immediately after deposit or deferred in time.
  • the mobile deposition zone 5 of each coloring substance 2 on the support 1 is permanently in the irradiation zone 6 of a laser beam corresponding infrared 4, the latter being applied continuously or only during the phases of actual deposition of the coloring substance concerned, in the form of permanent or impulse radiation.
  • each of the locations successively occupied by the mobile depot area 5 of each coloring substance 2 on the support 1 is irradiated by a beam infrared laser 4 after the deposition operation at this level location, with a time difference, the irradiation zone 6 according to the path previously defined on the surface 1 'of the support 1 by the projection directed from the coloring substance 2 concerned or traversing so systematic the entire area of support 1 having undergone a deposition of coloring substance 2.
  • the projection directions different liquid coloring substances 2 are convergent at level of a single mobile deposition zone on the surface 1 ′ of the support 1, a single laser beam 4 then irradiating either directly and immediately said deposit zone during the projection phase on the latter, that is to say subsequently the route previously defined on support 1 by the directed convergent projections of coloring substances.
