Abstract: Personalizing a multipage security document by placing a laser-alterable ink layer on a personalization area of an edge of each of the sequence of pages. The method includes revealing a portion of the personalization area of each of the sequence of pages relative to a pages above said each of the sequence of pages such that the personalization portion of each two consecutive pages in said sequence of pages are located adjacent to one another thereby producing a two-dimensional multi-page personalization section, and creating a pattern on the two-dimensional multi-page personalization section by altering the inked personalization area in the revealed portion of each page of said sequence of pages by exposing said revealed portions to a laser, such that a pattern is visible when the revealed portions of a sequence of pages are viewed simultaneously.

Abstract: Method for cutting an ink sticker situated in a multilayer structure having an ink layer between a protective layer and an ink carrier layer. by positioning the multilayer structure to be cut in front of a femtosecond laser device with the protective layer facing said femtosecond laser device and kiss cutting the ink layer through the protective layer with a laser beam emitted by the femtosecond laser device in order to produce an ink sticker between the protective layer and the uncut ink carrier layer, with the possibility to cut, partially cut or leave intact the protective layer.

Abstract: The present invention relates generally to a data carrier and a method for making the data carrier. More particularly, this invention relates to color laser marking of article, especially security documents. The present invention proposes a security document comprising a multilayers assembly instead of a single color component mixture in a layer. The multilayer assembly comprises at least two laser sensitive layer. Each layer comprises at least one coloring agent component. The order arrangement of the multilayers of bleachable coloring agent component is made so that each layer behaves as a wavelength filter configured to selectively transmit longer wavelengths and block or attenuate shorter wavelengths while protecting the underneath coloring agent component from bleaching interference.

Abstract: To place an insert cut out of film with no gaps in a cavity formed in a foil, after placing the foil on a supporting substrate, the cavity is punched into the foil by means of a tubular cutting punch comprising an inner pusher with a cutting edge in the required shaped of the cavity and the insert, so that the edge goes through the thickness of the foil and cuts a slug out of it; the punch is lifted with the slug held inside the punch, without moving the foil, the film is brought between the foil and the edge of the punch, the punch is lowered once again so as to cut the insert out of the film and then push the insert cut in that way in the cavity with a pusher, and the punch and the pusher are removed, with the insert held in place in the cavity.

Abstract: The present invention relates to a method (100) for personalizing a document, said document comprising a support comprising printed patterns (201, 202), wherein said method (100) comprises generating at least a laser pulse on said support for carbonizing at least a printed pattern.

Abstract: The present invention concerns a secure document comprising at least a personalized rainbow color micro-text with a text height inferior or equal to 300 ?m. The invention also concerns the method of production of said secure document. The present invention also concerns a method of production of a secure document comprising at least a personalized rainbow color micro-text with a text height inferior or equal to 300 ?m, said method comprising at least the following steps:—printing a rainbow color pattern on a predefined area of the secure document,—laser marking on the rainbow pattern of the predefined area, in order to form the personalized rainbow color micro-text on said predefined area. The laser marking can be laser blackening, laser whitening or a laser color change.

Abstract: A method designed to allow the printing of a matrix (MPC) of pixels, in N colours defining a colour coding system, on a selected part of a physical medium (MP). That method comprises a stage in which colour pixels are printed in at least one pass along oblique lines in relation to the physical medium (MP), wherein the pixels of an oblique line are all in the same colour selected from the N colours and different from that used for the previous oblique line, in order to generate a matrix (MPC) of M horizontal lines comprising P pixels each in the N colours successively in a selected order, and wherein each horizontal line other than the first one comprises a first pixel that is identical to the second pixel of the previous horizontal line.

Abstract: The invention concerns a support having a surface provided with personalizing data and including anti-counterfeit measures, arranged on at least part of the surface. The anti-counterfeit measures are configured to be modified in appearance under the effect of an additional personalization of the surface part and appear as defects visible at the surface of the card.

Abstract: The invention relates to a method for the laser marking of a support having a body and a cover sheet. A laser beam is used to etch the body of the support through the thickness of the cover sheet. The support is laminated either during or after the laser marking in order to reduce or prevent deformations in the cover sheet resulting from etching.

Abstract: The invention relates to the securing of information media so as to prevent any alteration or modification of the identification information and the fraudulent reuse of the media. The identification document according to the invention comprises personalisation information placed on at least one of its main sides, and invisible anti-forgery means placed on at least part of the said side and designed to undergo a change in appearance in the event of an attempt to do additional personalisation.

Abstract: The invention relates to a personalisable support comprising anti-forgery devices which are provided in order to indicate every attempt of fraudulent personalization. The support comprises a body (2) which is on one side equipped with personalization data (6,7) which are obtained by carbonization of the base material by means of a laser beam. The anti-forgery devices (8), which totally or partly cover these personalization data, draw a pattern (90, 80) along which bubbles (9) are created whose density (d1-d5) varies depending on the degree of carbonization of the areas (61-65) which are covered by the pattern.

Abstract: A data medium has at least first and second parts joined together, each having an outer face turned towards the outside and a hidden inner face. At least one of the first and second parts bears, at a certain distance from the outer faces, hidden markings corresponding to personalization data. This first part and preferably the second part of the medium are, at least locally, opaque with respect to through-transmission of laser radiation liable to modify the hidden markings.
