Definitions

• the technical field of the present invention is that of printing and more particularly that of making documents comprising a confidential text.
• third parties including printers and those responsible for sending them, should ignore. Only the recipient must read it.
• documents are sent by banks to their customers to disclose their credit card code to them, or by trustees to tell the occupants of a building what the code is to access them.
• the reverse side of such confidential texts is redacted, and often also redacted an envelope in which the document is located.
• Another financial institution uses an A4 format form which has in its lower left corner a precut heel on which an adhesive, carbonless, redacted label has been placed on its front.
• the code is written there using an impact printer. By peeling off the label, the code appears and is readable by any indiscreet person who, after reading, will replace the label exactly in its initial location, without the recipient being able to notice it. Confidentiality is therefore not guaranteed.
• Yet another financial institution sends its customers a more sophisticated document which includes a first sheet kept by the issuer which has a redacted area of intertwined letters and numbers and its back is completely coated with a carbonless layer while the customer receives a document in the form of a pocket glued on four sides by a tab precut in dotted lines.
• the front of the first copy in addition to the emblem of the issuer and the place of issue, contains an area where the customer's address and the reasons for non-distribution are printed, a small rectangular area dotted with numbers and interlaced letters intended to receive the code by carbonless duplication.
• IT prints the address by impact on the first sheet, it is found on the first copy of the cover.
• the confidential code is also impact printed on the redacted area, it is impossible to read it on the first copy of the cover, but it appears clearly on the front of the second copy.
• Yet another financial institution employs a similar document, but even more sophisticated because the pocket contains another pocket to pull from the first.
• the object of the present invention is to present a simple document, reliable as regards confidentiality, printed by laser or ink jet, therefore practical and economical.
• the present invention thus relates to a new document comprising a confidential inscription which should only be read by persons authorized to read it, characterized in that it includes a redacted area in which there is a non-stick area on which a film is placed.
• the adhesive at least partially transparent, for laser or inkjet printing and on the back of which is cut in advance, in the thickness of the document but without starting the film, a tab taking care to leave fasteners forming seals connecting the tab to the rest of the document, the confidential inscription being printed by laser or inkjet and the authorized person taking cognizance of the confidential inscription by detaching the precut tab by breaking the fasteners, making it easier to read if desired confidential text by gluing the back of the tab to the transparent adhesive film.
• the confidential text is printed by a laser or inkjet printer on the film and it is essential that the area of the tab to be detached is non-stick.
• the non-precut tabs on the tab serve to prove that no one tried to read the confidential text printed on the film before the recipient and therefore serve as seals.
• the carviardage must be sufficient to make it impossible to read the confidential text printed by laser or inkjet without detaching the tab after having broken the fasteners.
• the tab As soon as the tab has been removed, it is possible to read the confidential text on the film, but it is advisable to stick the back of the tab to it which allows a more comfortable reading of the confidential text, or at least lay the film flat on a flat surface, the color of which contrasts with the confidential labeling of the adhesive film.
• the new document of the invention allows traditional enveloping. It has no excess thickness except that of the adhesive film for laser printing or inkjet that the skilled person can make very thin, a few tens of microns, and it is well suited to modern methods of printing, with laser or inkjet printer. Confidentiality can be taken to the extreme since the operator of the printer can ignore the confidential information, for example the codes, that it prints. The very complexity of the prior art, and its non-adaptation to modern printing techniques prove that the present invention is not obvious to those skilled in the art.
• the redacted area of the document also includes a frame of small dots.
• point is understood to mean any small inscription because the usual circular shape of the points is not a characteristic of the invention.
• the presence of small dots is only intended to further hamper the reading of inscriptions made by laser printer or inkjet.
• the non-stick area has no appreciable thickness. This is achieved in particular by depositing the non-stick product, known to those skilled in the art, during the printing of redaction.
• a matt polyeslei adhesive film is used for laser or inkjet printing which is well known to those skilled in the art.
• the precut tab has no common edge with the edges of the entire document, and it thus forms are a kind of block. This characteristic is important to ensure perfect confidentiality because if the tab were to have a common edge with the document an eavesdropper could try to read the confidential text by slightly lifting the tab of the film.
• the confidential inscription is printed in reverse, that is to say that it is printed so that it can normally be read when the document returns to its reverse side after removing the pre-cut tongue.
• the adhesive film extends beyond the non-stick area and is bonded to it on the paper support so that when the film is separated from the support, the film does not tear while the paper support is defibiated.
• the precut tab projects beyond the adhesive film and the seals forming the seals are arranged. on the cut overhanging the adhesive film.
• This characteristic makes it possible both to reinforce the reliability of confidentiality by making obvious any attempt to read the confidential inscription and to more easily separate the precut tab from the film.
• at least one tab has been precut, for example of the shape and size of the last phalanx of the thumb, extending beyond the non-stick area, part of which is covered by the adhesive film while the other part overflows and has ties in the precut. This improvement makes it easier to detach the film from its paper support.
• the fasteners By pushing in with the thumb in the two-sided direction the part of the tab extending beyond the adhesive film, the fasteners are broken and the film is detached from its paper support, also initiating, if necessary, its defibration
• the part of the tab stuck to the adhesive remains there since the tab is precut around its entire periphery and we reveal the 'confidential registration directly above the redacted area on the film, and, if necessary, the paper backing is defibre outside the non-stick area.
• the redacted area covers the non-stick area around the periphery of which legible safety inscriptions have been printed which continue without breaking the non-stick area towards its exterior.
• the inscriptions are said to be legible if they can be read both on the redacted area and around it.
• the safety markings are white in the redacted area.
• the redacted area could also extend beyond the non-stick area with safety markings all in white.
• the inscriptions targeted by this last characteristic are said to be security because they constitute an additional means of improving the reliability of confidentiality insofar as, after having detached the tab from the film, it will not be possible to reconstitute the assembly without produce visible cracks in safety markings.
• the adhesiveness of the film on the surface which corresponds to the redacted area has been eliminated by applying a non-stick substance to the film before applying the adhesive thereto.
• This feature of the invention can be useful in preventing the recipient authorized to read the confidential inscription, to stick the film on any support.
• the user of a bank card may have the bad idea of sticking the film on it to have his code in mind whenever he uses his card.
• this practice is contrary to the recommendations of the banks which recommend that the codes be retained by heart and written down nowhere, the film can come off in the devices having to handle the card, in particular the ATMs, which can cause its breakdown.
• the non-stick substance interposed between the film and the adhesive of the adhesive film is a silicone.
• the present invention also relates to the method intended to prevent the reading of a confidential inscription printed by laser or inkjet in a redacted area of document in which there is a non-stick area, on which an adhesive film for laser or inkjet at least partially transparent, and on the back of which is cut in advance, in the thickness of the document but without starting the film, a tongue taking care to leave fasteners forming seals connecting the tongue to the rest of the document, the authorized person taking cognizance of the confidential inscription by detaching the precut tab by breaking the fasteners, facilitating if he so wishes his reading of the confidential text by gluing the back of the tab on the transparent adhesive film.
• the present invention also relates to the method intended to prevent an unauthorized third party from reading by leaving it intact a confidential document characterized in that the document is provided with at least one of the characteristics of the assembly constituted by the inscription confidential is written by laser printer or inkjet on an adhesive film directly above a redacted area, we add a screen in small dots in the redacted area of the document, the edges of the pre-cut tab are never confused with those of the confidential document, the surface of the confidential signs and characters is covered with ink or toner to less than 100%.
• redaction is an obstacle to the reading of an inscription, that a weft with small dots whose shape is not characteristic of the invention is an additional obstacle.
• the present invention further relates to the method intended to highlight any attempt to breach confidentiality in a confidential document according to the invention characterized in that it is at least one element of the assembly constituted by fasteners forming seals connect the tab pre-cut to the rest of the document, an adhesive film which cannot be lifted from its support, in the areas where it is not coated with a non-stick layer, without defibrating the backing paper, the non-stick area covers the redacted area and there have been printed on the periphery of the non-stick area safety inscriptions which continue without fracturing of the non-stick area towards its exterior and which are readable both in the non-stick area and outside.
• the invention also relates to the process for preparing a confidential document according to the invention, characterized in that a redacted area is printed on the document, including a non-stick area on which an adhesive film, at least partially transparent, is placed. , for laser or inkjet printing and on the back of the document, at the place where the film is located, a tongue is cut in advance, without cutting into the film, taking care to leave fasteners forming seals, then the confidential text is printed in the laser or inkjet in the zone delimited by the film by inkjet or by laser.
• the present invention also relates to the method for obtaining knowledge of a confidential text in a confidential document according to the invention, characterized in that the fasteners forming the seals of the precut tab are broken and that the confidential text is read on the adhesive film after, if desired, laying it flat on a plain surface whose color contrasts with the confidential inscription of the adhesive film.
• the present invention further relates to the method intended to prevent the adhesive film bearing the confidential inscription of the confidential document according to the invention from being able to be stuck on another support, characterized in that one interposed on the surface directly above the redacted area, between the film proper and the adhesive, a non-stick layer which may in particular be made of silicone.
• a non-stick layer which may in particular be made of silicone.
• a non-stick coating is deposited forming a block B of 76 by 20 mm located in the middle of block A.
• a permanent adhesive film of polyester mat for laser printing is deposited over the entire surface of block A 50 microns thick.
• a tab C of 60 by 15 mm, leaving eight fasteners which connect the tongue to the rest of the sheet, 4 fasteners are placed at the four corners of the tongue, the other four are regularly arranged every 20 mm along the two edges in length.
• the back of tab C is white and therefore does not bear any inscriptions.
• the present invention is in no way limited to the present example and to the explanations which preceded it and it also relates to all the achievements which are obvious to a person skilled in the art which arise from the spirit of the invention.
• the present invention is not limited to documents in A4 format which is in no way characteristic of the invention, nor to flat printing. We could just as easily use any other printing mode, especially continuous.
