Abstract:
(EN) The present invention pertains to a method for assessing the authenticity of printed matter and a method for preventing counterfeiting of printed matter. Printed matter (12) has a specific region (14) in which is printed a substance (26) that emits infrared rays (24) upon being irradiated with ultraviolet rays (16). This method has: a first step for irradiating the specific region (14) with ultraviolet rays (16); a second step for detecting infrared rays (24) that are emitted from the specific region (14) in accordance with the irradiation by the ultraviolet rays (16), and reading the shape of the specific region (14) or the intensity of the infrared rays (24); and a third step for determining the authenticity of the printed matter (12) on the basis of the result of the reading.
(FR) La présente invention concerne un procédé d'évaluation de l'authenticité de matière imprimée et un procédé pour empêcher la contrefaçon de matière imprimée. La matière imprimée (12) présente une région spécifique (14) dans laquelle est imprimée une substance (26) qui émet des rayons infrarouges (24) lorsqu'elle est irradiée avec des rayons ultraviolets (16). Ce procédé comprend : une première étape pour irradier la région spécifique (14) avec des rayons ultraviolets (16) ; une seconde étape pour détecter des rayons infrarouges (24) qui sont émis à partir de la région spécifique (14) en fonction de l'irradiation par les rayons ultraviolets (16), et la lecture de la forme de la région spécifique (14) ou l'intensité des rayons infrarouges (24) ; et une troisième étape pour déterminer l'authenticité de la matière imprimée (12) sur la base du résultat de la lecture.
(JA) 本発明は、印刷物の真偽判定方法及び印刷物の偽造防止方法に関する。印刷物(12)は、紫外線(16)を照射することで赤外線(24)を発光する物質(26)を印刷した特定領域(14)を有する。本発明の方法は、特定領域(14)に、紫外線(16)を照射する第1ステップと、紫外線(16)の照射に伴って特定領域(14)から放射される赤外線(24)を検出し、特定領域(14)の形状、若しくは赤外線(24)の強度を読み取る第2ステップと、読み取った結果に基づいて印刷物(12)の真偽を判定する第3ステップとを有する。
