Definitions
- the present invention relates to a document in booklet format, such as for example a passport in booklet format.
- a document in booklet format designates here a document comprising at least two pages linked by a hinge, often by sewing. For example, this is at least a cover page and a cover page.
- Such a document in booklet format also generally includes a notebook, that is to say a plurality of pages, also connected to the cover page by a hinge, often by sewing.
- the cover page (also referred to here as "datapage") often includes, for example, a plastic film, for example polycarbonate, which has at least one transparent window.
- the document when it is an identity document, the document includes security elements to authenticate the document and its holder in particular.
- Such security elements are for example a grayscale photo in the transparent window of the cover page and the same photo printed in color on the cover page (in particular on its internal face, that is to say in screw vis-à-vis the cover page, also called counterplate), which consists of printing a color photo (for example the portrait of the bearer) on the cover page of the document and having, on the cover page, a transparent window in which the same photo is engraved in grayscale.
- a grayscale photo in the transparent window is superimposed on the color photo.
- the transparent window can also be fitted with lenses and an image is engraved on it so as to give an impression of movement (image known as “SLI” for “Stereo Laser Image”): an observer then sees a sort grayscale 3D image in the transparent window, and this image is in color when superimposed on the color image of the cover page.
- image known as “SLI” for “Stereo Laser Image” an observer then sees a sort grayscale 3D image in the transparent window, and this image is in color when superimposed on the color image of the cover page.
- the object of the present application is to at least partially overcome the aforementioned drawback, also leading to other advantages.
- a document in booklet format comprising at least three pages connected by a hinge, two of the three pages being configured to rotate relative to a third of the three pages,
- the support page comprising at least one image
- a second of the three pages comprising at least one transparent window
- the document having at least a first opening configuration and a second opening configuration and passing from the first opening configuration to the second opening configuration by rotation of the first and second page around the hinge, relative to the third page; the document being characterized in that the image comprises at least two interlaced networks and the transparent window comprises at least one optical network,
- the optical network shifts, in a direction orthogonal to the hinge, from a first position, in which the optical network is superimposed on a first part of the image, to a second position, in which the optical network is superimposed on a second part of the image.
- the present invention makes it possible to take advantage of this offset of the pages relative to each other in a booklet.
- the relative positioning of the two pages which can be for example the cover page and the first cover page, depends on the opening angle of the document.
- a multitude of positions is made possible between a closing configuration in which the document in booklet format is closed (an angle between the two pages considered and at least a third page, for example the back cover page would then be 0 ° by convention ), and a maximum opening (which would conventionally correspond to an angle of 180 ° or even 360 ° with respect to the back cover page, in comparison with the closing configuration).
- the first opening configuration is a configuration in which the two pages are inclined at an angle "a" relative to the third page and the second opening configuration is a configuration in which the two pages are angled at an angle "a '", different from "a", relative to the third page.
- the different positions of the optical network have substantially the same coordinate according to the height of the document (that is to say in a direction parallel to the hinge) but different coordinates depending on the width of the document (that is to say according to a direction orthogonal to the hinge).
- the image or at least one of the networks can be in black and white, or any color in place of black, or "in color”, ie here monochrome (for example a grayscale image is considered here as “in color”) or polychrome.
- a “network” here designates a pattern repeated in steps.
- a network comprises for example a series of lines, straight or curved, parallel to each other, and two neighboring lines being distant from each other by a distance called "step".
- Each network is for example laser engraved or printed.
- the image of the support page and the optical network of the transparent window are configured to create an animated moiré effect when the optical network shifts from the first position to the second position relative to the 'picture.
- the moiré effect is thus intrinsically induced by the fact of opening or closing the document in booklet format.
- a first of the two networks of the image represents an object according to a first viewing angle and a second of the two networks of the image represents the same object from a second viewing angle, different from the first viewing angle.
- a first of the two networks of the image represents an object according to a first configuration and a second of the two networks of the image represents the same object according to a second configuration, different from the first configuration.
- the at least two networks of the image include a network of parallel lines.
- the optical network includes a network of parallel lines.
- the optical network is parallel to the networks of the image.
- the optical network is parallel to the hinge.
- a step of the network is for example orthogonal to the hinge.
- the transparent window has a pattern, engraved or printed.
- the optical network includes an array of lenses.
- Such a lens array can for example be formed in the transparent window during a rolling step of the corresponding page.
- the document comprising at least some of the characteristics described above forms a passport.
- the first of the two pages is a front cover page, the image being printed on a flap of the front cover page, and the second of the two pages is a cover page comprising holder identification data passport.
- the optical network can be the same for different documents or the transparent window can include a unique optical network for each document, for example defined by a code and this code can be represented elsewhere in the document.
- the present application finally relates to a batch of documents comprising several documents, each document comprising at least some of the characteristics described above, the optical network of the transparent window of one of the documents in the batch being different from the optical network of the transparent window of another of the documents in the batch, or even of all the other documents in the batch.

- FIG. 8 shows an optical network according to a second embodiment of the present invention.
- FIG. 9 shows an optical network according to a third embodiment of the present invention.
- Figures 1 and 2 show a document 10 in booklet format here forming a passport.
- a document in booklet format typically comprises a front cover page 11 and a rear cover page 12, usually formed from a single sheet folded in half.
- the sheet forming the front and back cover pages is generally cardboard and / or plasticized.
- such a document generally comprises a cover page 13 followed by at least a notebook 14, which comprises at least one page, more generally a plurality of pages.
- the at least one notebook 14, the cover page 13 and the front and rear cover pages are for example assembled by sewing, which then forms a hinge 15 around which the different pages can be turned to open or close the document. .
- the document may in particular take:
- an angle between at least the front cover page and the rear cover page is 0 °, that is to say that the front cover page is folded down substantially parallel on the cover page rear, with at least the cover page in between;
- At least one opening configuration in which, by convention, an angle between at least the front cover page and the rear cover page is greater than 0 °, and a maximum opening would correspond for example to an angle of 180 ° ( flat opening) or even 360 ° (the two cover pages are found one against the other back to back).
- FIG. 1 shows a document in booklet format open between the cover page before 1 1 and the cover page 13, and in FIG. 2, the same document is opened after the cover page 13, for example between the cover page 13 and a first notebook 14 (which first notebook may be unique or followed by at least one other notebook).
- first notebook 14 which first notebook may be unique or followed by at least one other notebook.
- the front cover page 1 1 alone ( Figure 1), or the front cover page 1 1 and the cover page 13 ( Figure 2) are opened with an angle "a" of about 90 ° relative to the back cover page 12 (serving here as a reference).
- the cover page 13 often includes at least one plastic film.
- FIG. 2 also shows that in the case of a passport, the cover page 13, also called “datapage”, notably includes various information related to the holder of the document, often printed on the back of the cover page 13.
- a security element is for example illustrated in Figures 3a to 3d.
- the document includes a grayscale image 17a in a transparent window 16 of the cover page 13 (FIG. 3b) and the same image 17b printed in color on the cover page 11 (in particular on its internal face, that is to say opposite the cover page, also called counterplate - Figure 3a).
- FIG. 3c schematically illustrating the flap movement of the cover page 13 on the front cover page 1 1 by rotation around the hinge
- the image in gray level in the transparent window is superimposed, in theory, on the color image (figure 3d).
- the subject of the present application proposes a security element based on a moiré effect.
- the transparent window 16 of the document (which is here the transparent window 16 of the cover page 13 of a passport) comprises an optical network 18.
- the optical network 18 here comprises straight lines, parallel to each other; two consecutive lines being one step apart "p". In addition, these straight lines are here parallel to the hinge (ie at the upper edge of the page shown in Figure 5).
- the transparent window 16 is laser engraved or printed with an array of lines.
- the optical network 18 can be identical for different documents or the transparent window 16 can comprise a unique optical network 18 for each document, for example defined by a code and this code can be represented elsewhere in document 10.
- the front cover page 1 As shown in Figure 6b, the front cover page 1 1, forming a support page, has an image 19, in color, here on its back.
- Image 19 is shown individually in Figure 6a.
- the image 19 here comprises three networks 19a, 19b, 19c, in color, interlaced (preferably, there are at least two).
- Each of the networks 19a, 19b, 19c of the image 19 here comprises a network of parallel lines; furthermore, these are straight lines parallel to those of the optical network 18 of the transparent window 16.
- the three networks 19a, 19b, 19c have for example a pitch denoted respectively "p '”, “p” "and” p '””.
- image 19 represents for example a portrait of the holder of document 10.
- a first of the three networks 19a represents the face of the holder from a first angle of view, for example from three quarters to the right
- a second of the three networks 19b represents the face of the holder from a second angle of view, for example from the front
- a third of the three networks 19c represents the face of the holder from a third angle of view, for example from three quarters to the left.
- FIGS. 7a to 7e show the effect induced by the superimposition of the transparent window 16 of FIG. 5 on image 19 of FIG. 6a, according to different angles of opening of the document, that is to say according to different relative offsets of the page comprising the transparent window 16 relative to the support page comprising the image 19.
- At least the support page and the page comprising the transparent window are opened at an angle "a" with respect to a third page of the document, for example by report to the back cover page.
- the two aforementioned pages are superimposed on each other with an offset, indicated here first offset.
- FIG. 7b shows that the window descends (by definition) relative to the image.
- the offset also changes: for a third opening angle “a” ”there is then a third offset and in the present exemplary embodiment, the figure 7c then shows that the window still descends relative to the image.
- FIGS. 7a to 7c thus show that, depending on the opening angle, the optical network 18 shifts from a first position (FIG. 7a), to a second position (FIG. 7b), then to a third position ( figure 7c) compared to the image.
- this shift of the optical network 18 (and here of the transparent window 16) relative to the image 19 of the support page takes place in a direction orthogonal to the hinge.
- the optical network 18 is superimposed on a first part of the image 19, then on a second part of the image 19, then on a third part of the image 19.
- the optical network 18 reveals a first of the networks 19a of image 19 of the support page (FIG. 7a), or a second of the networks 19b of image 19 (FIG. 7b) or a third of the networks. 19c of image 19 (figure 7c).
- the optical network is shifted inversely as illustrated in the figures 7d and 7e, where the networks 19b then 19a again appear.
- Image 19 of the support page and the optical network 18 of the transparent window 16 are thus configured to create an animated moiré effect when the optical network 18 shifts from the first position to the second position, or even to a third position. etc, compared to image 19.
- the networks of the image can represent the same image in two different configurations, other than a simple change of point of view.
- the first network 19a represents the holder with his glasses and the second network 19b represents the holder without glasses, or the first network 19a represents the smiling holder and the second network 19b represents the holder without smiling etc.
- the interlaced networks can represent completely different images.
- the optical network 18 can comprise any other type of network, for example curved lines 18a as shown in FIGS. 8, and / or also include a pattern 18b, engraved or printed, for example alphanumeric data as shown schematically in Figure 9, for example biographical.
- the image 19 is then split into networks established accordingly.
- the optical network of the transparent window may, in addition or instead of the network of lines (whatever it is, of straight lines or curves), comprise a network of lenses.
- the optical network 18 only comprises a network of lenses, the result obtained will be similar to that shown diagrammatically in FIGS. 7a to 7e but in less dark.
