Definitions

  • the invention relates to a process for printing a material. More specifically, the invention makes it possible to decorate any material with a multicolored pattern produced beforehand and consisting of a combination of elementary shapes.
  • the method of the present invention will in particular be intended for the production of flexible pieces such as flags or drapes for furniture. However, it could be envisaged to use the method to decorate other pieces such as semi-rigid and rigid sheets such as for example sheets of cardboard or metal.
  • the multicolored decorations are produced beforehand by various known printing processes. Generally, these prints are assigned in large series according to well-defined and fixed criteria, colors and patterns.
  • the object of the present invention is to propose a process for printing a material, by which it is decorated with a multicolored pattern, in particular intended for the production of flexible pieces such as flags or curtains of furniture, which allows respond to the difficulties and overcome the above-mentioned drawbacks.
  • An object of the present invention is to propose a process for printing a material which can make it possible to decorate a material with a multicolored pattern produced beforehand by composition, thus authorizing all the designs of patterns.
  • Another object of the present invention is to provide a process for printing a material which allows the advantages of so-called sublist printing to be retained while allowing the shapes, colors and arrangements of the pattern to be adjusted as desired.
  • the method of the present invention allows quite diverse printing realizations and authorizes according to desires all creations and all dimensions without having the obligation to have patterns, or models pre-stored in each printing to be produced .
  • Another object of the present invention is to provide a process for printing a material which allows flexible parts to be produced either individually or in limited series.
  • Another object of the present invention is to provide a method of printing a material which allows the production of decorated pieces which has an integrity aesthetic quality and a high mechanical resistance.
  • FIG. 1 represents a front view of a finished material decorated according to the method of the present invention.
  • FIG. 2 shows a sectional view of a base bundle of colored sheets necessary for the implementation of the method of the present invention in order to obtain the decorated material represented in FIG. 1.
  • Figures 3a to 3d show in detail the composition of the bundle shown in Figure 2.
  • Figure 4 shows a sectional view of another phase of the printing process of the present invention showing the composition of the pattern on the decoration according to Figure 1 before its transfer to the material to be decorated.
  • FIG. 5 shows another configuration of finished material decorated according to the printing method of the present invention.
  • FIGS. 6a to 6c show the composition of the bundle necessary for the implementation of the printing process of the invention to obtain the material represented in FIG. 5.
  • FIG. 7 represents a phase of the method of the present invention showing the composition of the multicolored pattern before it is transferred to the material to obtain the representation of FIG. 5.
  • the present invention relates to a process for printing a material by which it is decorated with a multicolored pattern in a single print.
  • the multicolored pattern Prior to printing, the multicolored pattern is produced on a temporary support using inks capable of being transferred to the said material by heat and pressure, a technique more generally known to those skilled in the art under the name of process. sublimation or sublistatic printing.
  • Figure 1 shows for example the aesthetics of a flag made of a flexible textile material and whose multicolored pattern is constituted by an association of primary elementary shapes, such as any geometric shapes, letters or numbers, each having a primary color .
  • FIG. 1 shows a flag whose background 1 is colored and which carries in well determined locations primary elementary shapes such as a colored star 2, a colored patch 3 and a colored letter 4.
  • primary elementary shapes such as a colored star 2, a colored patch 3 and a colored letter 4.
  • the background 1, l 'star 2, the patch 3 and the letter 4 have different colors so as to be distinguished from each other according to criteria desired by the manufacturer or the user.
  • the different colors making up the decorated material will be called primary colors, and there will be as many primary colors as colors or tones in the final multicolored pattern.
  • FIGS. 1 to 4 illustrating the process for printing a material of the invention which will be described, four different colors are used one of the other identified on the drawings by hatching, but this is in no way limiting and one could consider either a lower number of colors or a higher number of colors.
  • an adhesive coating on the surface compatible with sublimable inks, resistant to pressure, to heat and of the type used, is used to constitute these means for maintaining the relative positioning of the sheets 6 to 9. removable.
  • these adhesive coatings will not be prejudicial during the transfer and more precisely to the migration of the dyes from the temporary support sheet 15 to the material 14.
  • they will also facilitate the separation of the colored sheets 6 to 9 necessary during the composition phase on the temporary support 15 of the multicolored decor pattern by superimposition and juxtaposition of the primary elementary forms 1 to 4 precut.
  • the contours 10 to 13 of the elementary shapes 1 to 4 of the decorative pattern relative to the external contour 14 of the material to be decorated are simultaneously formed on each sheet 6 to 9 of said bundle 5 by cutting to the laser of the whole bundle 5.
  • the multicolored decorative pattern 16 is composed on the temporary support 15 by taking from a bundle 5 the elementary shapes 1 to 4 precut from the final pattern in each colored sheet 6 to 9 of corresponding primary color. to constitute and form by juxtaposition and / or superposition of the elementary precut shapes 1 to 4 the different colored zones of the final pattern. Due to the simultaneous pre-cutting of the bundle 5, it should be noted that the elementary shapes are identified and positioned mutually perfectly; thus the operator responsible for the composition is not obliged to have recourse to other separate references as is the case for example in screen printing.
  • the different shapes 1 to 4 thus positioned are fixed on the temporary support 15 by means of adhesive means which will advantageously be in the form of an adhesive coating of the same constitution and property as that used previously to maintain the positioning relative of the leaves in the bundle.
  • the color yellow is easily crossed and masked by darker colors such as black, blue, red; in these cases, you should avoid superimposing yellow elementary shapes on other darker shapes.
  • the elementary forms of dark colors could be superimposed on forms of lighter colors without prejudice.
  • composition showing the juxtaposition and the superposition is represented in figure 4.
  • the elementary form 2 is of light color such as in particular yellow, it will not be superimposed on an elementary form 1 which would be of darker color such than red for example, so we will remove the precut area in the red sheet 6 constituting the background of the flag and we will replace it with the elementary shape 2 of the yellow color corresponding to the final pattern.
  • Figure 5 shows a material decorated in another multicolored pattern. This material shows in particular on a light plain background inscriptions of dark colors.
  • FIG. 6 is shown a bundle 5 constituted for the example of two sheets of primary colors, one light marked 7 and the other dark marked 9, and a neutral interlayer sheet 18.
  • the aim of the operation is therefore to obtain dark inscriptions 20 on a light background 20.
  • a neutral sheet 18 serving as a mask and on which the inscriptions 20 will be cut will be inserted.
  • the cuts can be carried out simultaneously in the whole bundle in which one or more neutral sheets 18 will have been inserted. Nevertheless, when inscriptions having very large cuts, it will be advantageous to avoid making these cuts in certain sheets 6 to 9 making up the bundle 5 and they will only be made in the neutral sheets 18. This possibility being chosen in particular by the operator at the time of manufacture according to the criteria required for the decor pattern.
  • the known traditional technique known as sublistatic is then used.
  • the material 17 to be decorated consists of a flexible, light and very resistant material such as a neutral or colored natural or synthetic fabric, for example a polyester fabric of 50 to 200 g / m2.
  • the material could more generally consist of any support capable of fixing the sublimable inks.
  • it could even consist of sheets of cardboard or metal sheets.
