- the quantity of the mixture spread on the screen printing screen for the second printing is adjusted to correspond to a thickness of between 10 ⁇ m and 20 ⁇ m.
- the screen printing screen used is such that the second impression is of the continuous type, that is to say forms a continuous layer 5 completely covering the first discontinuous impression 3 (FIG. 2), and thus constitutes a first layer of a film. .
- the same screen screen can be used to simultaneously produce a plurality of films.
- Each layer 5 of the second impression has a dimension and peripheral shapes corresponding to those of the document surface portion to be protected.

AD45 or ADTH from the company CHIMITEC (France).
- FIG. 3a This gives a protective transfer 14a as shown in FIG. 3a comprising a support sheet 1 and a film 7a comprising a layer of polyurethane 5 and an adhesive layer 6.
- the layer 5 of polyurethane does not adhere to the varnish of the first impression 3 nor to the support sheet 1 can be separated as shown in FIG. 4.
- the film 7a then has, opposite to the layer of adhesive 6, a face 8 having a glossy imprint 9 left by the varnish 3 from the first impression, this imprint 9 forming a discontinuous sign or pattern exposed to sight preventing reproduction by optical reading. In fact, this imprint 9 is shiny because the face 4 of the varnish 3 with which it was in contact is also shiny.
- the rest of the face 8 of the film 7a is mat, or in any case less shiny than the imprint 9, like the non-shiny surface 2 of the support sheet 1.
- the shiny imprint 9 is recessed in the thickness of the film 7a relative to the rest of the face 8 (FIG. 4) of a height corresponding to the thickness of the first impression 3, in particular between 2 and 10 ⁇ m.
- the imprint 9 formed on the film 7a has a gloss measured in white light with the BYK GARDNER glossmeter greater than 68% at 85 degrees (angle of incidence of light) and greater than 70% at 60 degrees.
- the rest of the face 8 of the film on the contrary, has a gloss less than 26% at 85 degrees and less than 16% at 60 degrees, and is therefore matt.
- the surface condition of the film 7a corresponds to the surface condition of the support 1 on which it has been applied for its manufacture by screen printing.
- any material other than polyurethane meeting this condition, and which allows the subsequent separation of the film and the support sheet 1, can be envisaged.
- FIG. 3b represents an alternative embodiment of a protection transfer 14b in which the film 7b is of the multilayer type.
- an additional discontinuous layer 10 is produced with a colored interlayer printing visible through transparency through the layer 5 formed by the second printing 5 which is itself transparent.
- At least one other continuous additional layer 11 is then produced before complete polymerization of the discontinuous layer 10, then the adhesive layer 6 is applied.
- the film 7b is then obtained comprising the continuous layer 5 of polyurethane of the second impression which will be provided with glossy imprints 9 preventing reproduction by optical reading, the discontinuous layer 10 of colored polyurethane, the continuous layer 1 1 of polyurethane and the layer 6 of adhesive material.
- each layer of film 7a is produced. 7b with the exception of the adhesive layer 6, by printing a two-component polymerizable printing composition in situ leading, after polymerization, to a layer of polyurethane.
- a polyurethane composite film 7a, 7b is thus obtained, with, in the multilayer variant 7b, an integrated pattern or sign, the different layers 5, 10, 1 1 are not separable.
- each layer continues 5, 11, 6 of the film 7a, 7b is transparent, so that the film can be used to cover and protect the surface of a document by allowing the reading of inscriptions carried by this document and / or by the film itself (in particular the patterns or signs of discontinuous interlayer printing 10).
- the support sheet 1 is opaque, so that it is easier to subsequently recognize the presence of the imprints 9 by transparency through the film.
- the first impression 3 is produced so that the glossy imprint 9 is formed at least opposite portions of the film 7a, 7b intended to be applied to areas of the document 12 to be protected and / or film 7a, 7b, bearing inscriptions which must be visible through transparency such as a pasted or printed photograph, a hologram inserted in film 7b, or the like.
- the film 7a, 7b has improved transparency in its portions opposite the bright imprint 9.
- Figures 5 to 7 illustrate a method of using a protective transfer 14a or 14b as obtained and shown in Figures 3a or 3b, and comprising a support sheet 1 of opaque mat polystyrene and a protective film 7a or 7b .
- the transfer 14a is chosen to the dimensions of the surface 13 of the document 12 to be protected. It is presented with the layer 6 of adhesive material oriented towards the surface 13, the support sheet 1 being opposite. The layer 6 of adhesive material is then applied against this surface 13 to be protected, so as to adhere the film 7a or 7b to this surface 13. In the case of a self-adhesive, it suffices to apply pressure. In the case of a hot-reactivatable adhesive, the transfer 14a, 14b or, at the very least, the layer 6 of adhesive material is heated beforehand and / or during application. After application and adhesion, the support sheet 1 is separated from the film 7a, 7b as shown in FIG. 6.
- the scraping of the imprint 9 has the consequence of damaging the polyurethane film 7a, 7b and does not erase the shiny pattern or sign formed by this imprint 9. In this way, it is not possible to restore the photocopiable nature of the document by scratching. Thus, it is strictly impossible to reproduce by photocopy or using a scanner the inscriptions carried by the document 12 on the surface 13 and / or by the film 7a, 7b, itself, even if these inscriptions are visible. through the film 7a, 7b.
- the invention can be the subject of multiple variants.
- the film 7a, 7b can be applied to only part of the surface 13 to be protected and several films 7a, 7b can be applied to the same surface 13 of the document.
- the film 7a, 7b can be formed from a greater number of layers.
- Other printing methods can be used to make the film, and with other synthetic materials.
