Description
PROCEDE D'INSCRIPTION D'UNE SEQUENCE DE CARACTERES ET SUPPORT COMPORTANT UNE INSCRIPTION OBTENUE SELON LE PROCEDE L'invention concerne un procédé d'inscription d'une séquence de caractères destinée à être cachée un pavé grattable ou effaçable. Elle concerne également un support comportant au moins une zone inscrite selon le procédé. The invention relates to a method for registering a sequence of characters intended to be hidden, a scratch-off or erasable block. It also relates to a support comprising at least one zone inscribed according to the method.
On entend par pavé grattable ou effaçable, tout motif imprimé sur un support dans le but d'être ôté soit par simple grattage avec un ongle ou tout et de dureté suffisante soit avec un dissolvant classiquement de l'alcool), l'objectif étant généralement de découvrir une inscription ou un dessin imprimé sous ledit pavé. The term “scratchable or erasable pad” means any pattern printed on a support in order to be removed either by simple scraping with a nail or all and of sufficient hardness or with a conventional solvent for alcohol), the objective generally being to discover an inscription or a drawing printed under said paving stone.
On parlera dans la suite pour simplifier de pavé grattable. We will talk in the following to simplify scratching pad.
Jusqu'à présent on a utilisé des technologies impression par sérigraphie ou par transfert thermique pour réaliser les pavés grattables. Until now, screen printing or thermal transfer printing technologies have been used to make the scrapable pavers.
Dans les deux cas, le matériau utilisé pour 'impression, possède un bon pouvoir couvrant et une adhérence suffisante par rapport au support pour ne pas 'en aller de lui-même, mais une adhérence insuffisante pour pouvoir résister au grattage. In both cases, the material used for printing has good covering power and sufficient adhesion relative to the support so as not to go away by itself, but insufficient adhesion to be able to resist scratching.
Le déposant a également développé une technologie par jet d'encre pour réaliser les pavés grattables sur support papier ou plastique. The depositor has also developed an inkjet technology for producing the scrapable pavers on paper or plastic support.
On s'intéresse dans ce qui suit à l'inscription cachée par le pavé grattable. We are interested in what follows in the inscription hidden by the scratching pad.
L'invention s'applique tout particulièrement à 'inscription cachée par un pavé grattable de séquences de caractères sur des billets, des billets de jeu (loterie et autres). Elle s'applique bien sûr aussi à l'inscription cachée par un pavé grattable de séquences de caractères sur des supports plastiques (PVC). Elle s'applique aussi à des supports électroniques portables tels que les cartes à puces. The invention applies very particularly to the inscription hidden by a scratch-off block of sequences of characters on tickets, game tickets (lottery and others). Of course, it also applies to the inscription hidden by a scrapable block of character sequences on plastic supports (PVC). It also applies to portable electronic media such as smart cards.
Dans toutes ces applications le pavé grattable est destiné à cacher l'inscription qui doit rester secrète pour le public. En effet, l'inscription est destinée à être decouverte par la personne qui aura achete ce support quel qu'en soit l'utilisation (jeu, téléphone etc. ). In all these applications, the scratch-off pad is intended to hide the inscription which must remain secret to the public. Indeed, the registration is intended to be discovered by the person who will have bought this support whatever its use (game, telephone etc.).
Malheureusement le déposant a constaté qu'il etait possible en effectuant un sondage au moyen de micro- pointes à travers le pavé grattable et cela de manière invisible à 1'#i1 nu, d'arriver à déterminer la séquence inscrite sous le pavé. Unfortunately, the applicant has noted that it was possible by carrying out a survey by means of microtips through the scrapable pad and this invisible to the naked eye, to arrive at determining the sequence inscribed under the pad.
Le déposant a découvert également notamment dans le cas cartes plastiques à pavé grattable 'il suffisait de sonder au moyen de quatre lignes de micro pointes pour arriver à découvrir la séquence inscrite sous pavé. The depositor also discovered, in particular in the case of plastic cards with scratch-off paving stones, it was enough to probe by means of four lines of micro tips to arrive at discovering the sequence inscribed under paving stone.
L'invention à pour but de résoudre ce problème. The invention aims to solve this problem.
A cette fin, l'invention a pour objet un procédé d'inscription d'une séquence de caractères destinee à être cachée par un pavé grattable, principalement caractérisé en ce que ledit procédé consiste à inscrire les caractères de manière à ce que leur position y) sous le pavé soit pseudo-aléatoire. To this end, the subject of the invention is a method of registering a sequence of characters intended to be hidden by a scrapable pad, mainly characterized in that said method consists in registering the characters so that their position y ) under the pavement is pseudo-random.
Selon une autre caractéristique, le procédé consiste à inscrire chaque caractère de manière à ce que leur position suivant l'axe des ordonnées reste constante et leur position suivant l'axe des abscisses varie de manière à obtenir des caractères ayant un espacement variable. According to another characteristic, the method consists in inscribing each character so that their position along the ordinate axis remains constant and their position along the abscissa axis varies so as to obtain characters with variable spacing.
Selon une autre caractéristique, le procedé consiste à inscrire chaque caractère de manière à ce que leur position suivant l'axe des abscisses reste constante et leur position suivant l'axe des ordonnees varie de manière à obtenir une séquence de caractères non régulièrement alignés. According to another characteristic, the method consists in writing each character so that their position along the abscissa axis remains constant and their position along the ordinate axis varies so as to obtain a sequence of characters which are not regularly aligned.
Selon une autre caractéristique, le procedé consiste à inscrire les caractères avec des formats différents (polices de caractères différentes et ou taille de caractères différente). According to another characteristic, the method consists in writing the characters with different formats (different fonts and or different character size).
Bien entendu toutes les variations proposées peuvent être combinées. Of course all the proposed variations can be combined.
Selon une autre caractéristique, l'inscription est réalisée par impression. According to another characteristic, the registration is carried out by printing.
Avantageusement, l'impression est réalisée par une machine à jet d'encre. Advantageously, the printing is carried out by an inkjet machine.
L'invention concerne avantageusement un support pour l'inscription de séquences de caractères cachées par un pavé grattable principalement caractérisé en ce qu'il comporte au moins une zone dans laquelle une sequence de caractère est inscrite selon l' quelconque des caractéristiques du procédé. The invention advantageously relates to a support for the recording of sequences of characters hidden by a removable scratchpad mainly characterized in that it comprises at least one zone in which a sequence of characters is written according to any one of the characteristics of the process.
Selon les applications de l'invention ledit support en plastique. According to the applications of the invention, said plastic support.
Le support peut être constitué par une carte à puce notamment dans le cas d'application de l'invention à teléphonie et en particulier à la téléphonie mobile. The support can be constituted by a smart card in particular in the case of application of the invention to telephony and in particular to mobile telephony.
Le support est en pâte à papier rigide (carton) ou souple (papier) dans des applications billetterie ou jeux (loto). D'autres particularités et avantages de l'invention apparaitront clairement à la lecture de la description qui est faite ci-après et qui est donnée titre d'exemple non limitatif en regard des dessins annexés, sur lesquels les figures 1 à 4, représentent différentes séquences de caractères inscrites selon le procédé conforme à l'invention, la figure 5, représente une carte (plastique ou carton) support d'une inscription selon l'invention. Les figures 1 à 4 illustrent des variantes possibles selon le procédé de l'invention et la séquence de caractères illustrée est une séquence alpha numérique. The support is made of rigid (cardboard) or flexible (paper) paper pulp in ticketing or games (lotto) applications. Other features and advantages of the invention will appear clearly on reading the description which is given below and which is given by way of nonlimiting example with reference to the appended drawings, in which FIGS. 1 to 4 represent different sequences of characters registered according to the method according to the invention, FIG. 5 represents a card (plastic or cardboard) supporting an inscription according to the invention. Figures 1 to 4 illustrate possible variants according to the method of the invention and the illustrated sequence of characters is an alpha numeric sequence.
Le procédé selon l'invention propose d'introduire un aléa d'impression dans la séquence de caractères empêchant toute lecture de cette dernière tant que la pellicule à gratter n'a pas été retirée lui conservant son caractère lisible après retrait de cette pellicule. The method according to the invention proposes to introduce a printing hazard into the character sequence preventing any reading of the latter as long as the scratch-off film has not been removed, retaining its readable character after removal of this film.
Les figures 1 à 4 illustrent un pavé 2 après grattage de la pellicule qui cache la séquence. Figures 1 to 4 illustrate a block 2 after scraping the film which hides the sequence.
L'aléa d'impression introduit porte sur la position x,y caractères et ou leur format. The printing hazard introduced relates to the position x, y characters and or their format.
Pour la position on peut agir sur la position en abscisse x et ordonnée y ou en abscisse seulement ou en ordonnée seulement. For the position one can act on the position on the x-axis and the y-axis or on the x-axis only or on the x-axis only.
Dans le cas où l'on agit en abscisse x et en ordonnée y on obtient une séquence selon la figure 1. Dans le cas où on agit en abscisse x, l'ordonnée restant fixe yo.on obtient une séquence telle que représentée sur la figure 2. Dans le cas où on agit sur l'ordonnée y, l'abscisse restant fixe, on obtient un espacement constant d entre les caractères comme l'illustre la séquence représentée sur figure 3. In the case where we act on the abscissa x and on the ordinate y we obtain a sequence according to FIG. 1. In the case where we act on the abscissa x, the ordinate remaining fixed yo, we obtain a sequence as represented on the figure 2. In the case where one acts on the ordinate y, the abscissa remaining fixed, one obtains a constant spacing d between the characters as illustrated by the sequence represented in figure 3.
Dans le format des caractères, on peut agir sur police et ou sur la taille. La figure 4 illustre différentes polices et tailles pour les caractères Cette figure 4 illustre d'ailleurs une combinaison diverses possibilités proposées selon le procédé. In the format of the characters, one can act on font and or on the size. FIG. 4 illustrates different fonts and sizes for the characters This FIG. 4 moreover illustrates a combination of various possibilities proposed according to the method.
La figure 5 illustre une carte plastique ou carton 1 comme support comportant une zone 10 d'inscription selon le procédé. FIG. 5 illustrates a plastic card or cardboard 1 as a support comprising an area 10 for writing according to the method.
Le support est en plastique dans le d'applications carte à puce. The support is plastic in the smart card applications.
peut s'agir de tout autre support par exemple papier ou carton pour des applications billetterie jeu (loto). may be any other medium, for example paper or cardboard for game ticketing (lotto) applications.
inscription des séquences de caractères selon procédé peut être faite par impression au moyen de toute technique d'impression adaptée au support. recording of character sequences according to the process can be done by printing using any printing technique suitable for the medium.
impression par jet d'encre sera choisie préférentiellement dans la mesure où cette technique est très souple à l'utilisation et permet d'avoir des cadences industrielles y compris pour l'impression carte de type cartes à puce. inkjet printing will preferably be chosen insofar as this technique is very flexible to use and makes it possible to have industrial rates, including for card printing of the smart card type.
Un programme de pilotage des têtes à jet d'encre d' machine d'impression à jet d'encre comporte paramètres de position (x, y) et de format des caractères à imprimer. A program for controlling the inkjet heads of an inkjet printing machine comprises position (x, y) and format parameters for the characters to be printed.
Pour la mise en #uvre du procédé, ce programme est modifié de manière à introduire des variations pseudo- aleatoires dans ces paramètres.For the implementation of the method, this program is modified so as to introduce pseudo-random variations in these parameters.
