Definitions
- the present invention relates to a generation method using electronic means of a drawing of security intended to be printed on securities, including bank notes and fiduciary papers, composed of multiple lines, as well as a plate printing and value paper bearing at least a drawing generated by the implementation of the method.
- EP-A-0204 552 a safety drawing is described comprising areas formed by non-parallel lines, whose width and / or distance vary.
- the choice of particular security drawings allows cause the appearance of moiré.
- the purpose of this invention is to provide a method for generating moiré drawings when copied digital.
- the invention therefore provides a method of generation of designs based on multiple lines.
- An important advantage of the invention is the fact that it allows you to create security drawings including geometric or artistic images while so far safety drawings of this type do not include no geometric or artistic images.
- the lines of the bottom can be turned from a certain angle ⁇ partially or totally or we can turn according to this angle only the line segments at inside a contour delimiting an image.
- said lines are cut out, so interrupted inside the delimiting contour the image.
- the lines are modulated by the form (outline) of an image and we create a relief effect by known means, in particular by breaking the continuity lines.
- the width of the lines is modified according to the density of the gray of the image original geometric.
- the line segments do not contributing to the formation of an image retain their width and spacing respecting the defined r0 ratio in step c of the method.
- the width of the lines is modified according to the original digital image obtained by a scanner.
- the present invention also relates to a plate with at least one drawing generated according to one of claims 1 to 8 intended for printing of a security paper.
- the invention also relates to a security paper comprising at least one safety drawing generated according to one of claims 1 to 8.
- Figures 2 to 4 show the modification of a network of regular lines according to a variant of the invention.
- Figures 5 to 5 show the modification of a network lines according to another variant of the invention.
- ⁇ being a modulation parameter of the line width.
- N is the modulation period.
- FIG. 7 Another modification step after obtaining the figure 7 is to modify the shape of the lines while respecting the width of the lines obtained for example in the figure 4 or 7.
- FIG. 8 which is identical to figure 7 we can get the figure 9 which is formed of lines forming waves or sinusoids.
- FIG. 10 and 11 where FIG. 10 is identical to FIG. 7, one can transform these lines into concentric closed curves respecting the width of the lines in the figure 10.
- the form of this transformation of lines straight in closed curves is not limited and it depends on the desired result.
- the invention also relates to a printing plate. provided with at least one safety drawing created according to one described methods as well as a security paper provided at least one such drawing.

Description
Claims (10)
- Méthode de génération à l'aide de moyens électroniques d'un dessin de sécurité destiné à être imprimé sur des papiers-valeurs, notamment billets de banques et papiers fiduciaires, composé de lignes multiples, caractérisée par le fait que l'on procède selon les étapes suivantes :a) on génère un fond uniforme constitué de lignes droites parallèles de sorte que la distance entre les axes médians longitudinaux des deux lignes consécutives que l'on désigne par l'espacement d₀ entre deux lignes soit constant et que la largeur l₀ des traits de lignes soit également constante, déterminant ainsi un rapport constant r₀ = l₀/d₀.b) on modifie le fond en modulant l'espacement d₀ entre les lignes selon une fonction de modulation dont les paramètres sont choisis préalablement,c) on modifie la largeur des traits de lignes de sorte que le rapport de la largeur ln du trait d'une ligne sur son espacement dn à la ligne suivante soit égal au rapport constant ln/dn = r₀.
- Méthode selon la revendication 1, caractérisée par le fait que lesdites lignes droites sont transformées en des lignes de forme différente, la largeur du trait de chaque ligne étant égale à la largeur obtenue à l'étape C de la revendication 1.
- Méthode selon l'une des revendications 1 ou 2, caractérisée par le fait qu'au moins une partie desdites lignes sont soumises à une rotation d'un angle α.
- Méthode selon l'une des revendications 1 à 3, caractérisée par le fait que dans le but de former une image, lesdites lignes sont découpées à l'intérieur des contours délimitant ladite image.
- Méthode selon l'une des revendications 1 à 4, caractérisée par le fait que dans le but de former une image en relief, lesdites lignes sont modulées par la forme de l'image et transformées pour créer un effet de relief.
- Méthode selon l'une des revendications 1 à 5, caractérisée par le fait que dans le but de former une image géométrique, la largeur des traits est modifiée le long de chaque ligne en fonction de la densité du gris de l'image géométrique d'origine.
- Méthode selon l'une des revendications 1 à 4, caractérisée par le fait que dans le but de créer une image artistique, la largeur des traits est modifiée le long de chaque ligne en fonction de l'image numérique originale scannée.
- Méthode selon l'une des revendications 4 à 7, caractérisée par le fait que les segments de lignes ne contribuant pas à la formation de l'image présentent une largeur et un espacement respectant le rapport r₀.
- Plaque d'impression pour l'impression de papiers-valeurs, caractérisée par le fait qu'elle est munie d'au moins un dessin de sécurité généré par la méthode selon l'une des revendications 1 à 8.
- Papier-valeur, caractérisé par le fait qu'il est muni d'au moins un dessin de sécurité généré selon la méthode de l'une des revendications 1 à 8.
