阅读说明：本技术 安全装置及其制造方法 (Security device and method of manufacturing the same ) 是由 达里尔·芒迪 于 2018-05-09 设计创作，主要内容包括：公开了一种安全装置,包括：第一油墨(21)和第二油墨(22),各自分别布置在安全装置的侧向偏移的第一和第二区域中,第一和第二油墨各自包括各自的发光材料,两种发光材料都响应于紫外光谱中的至少一个激发波长的辐射而发光,在不存在至少一个激发波长的情况下,使用可见光照射时,第一和第二油墨各自呈现基本上彼此相同的非发光可见颜色；并且当使用可见光和至少一个激发波长的组合照射时,第一和第二油墨各自呈现不同于非发光可见颜色并且彼此不同的可见颜色；第三油墨(23),布置在与装置的第一和第二区域侧向偏移的装置的第三区域中,第三油墨不会响应至少一个激发波长而发光,并且在不存在至少一个激发波长的情况下,使用可见光照射时,第三油墨呈现与第一和第二油墨基本上相同的非发光可见颜色；以及布置成掩蔽图案的第四油墨(24),第四油墨与第一区域中的第一油墨和/或第二区域中的第二油墨的一个或多个部分部分地交叠,第四油墨不会响应至少一个激发波长而发光,并且在不存在至少一个激发波长的情况下,使用可见光照射时,第四油墨呈现与第一、第二和第三油墨的非发光可见颜色不同的可见颜色。在不存在至少一个激发波长的情况下,使用可见光照射安全装置时,第一、第二和第三区域一起显示为以非发光可见颜色的一个连续图案,而第四油墨使形成连续图案的多于一种油墨的存在模糊化,并且当使用可见光和至少一个激发波长的组合照射安全装置时,第一和第二区域变得可见地彼此不同,并且与连续图案的其余部分可见地不同。(Disclosed is a safety device including: a first ink (21) and a second ink (22), each respectively arranged in laterally offset first and second regions of the security device, the first and second inks each comprising a respective luminescent material, both luminescent materials emitting light in response to radiation of at least one excitation wavelength in the ultraviolet spectrum, the first and second inks each exhibiting a non-luminescent visible color that is substantially the same as one another when illuminated with visible light in the absence of the at least one excitation wavelength; and the first and second inks each exhibit a visible color that is different from the non-luminescent visible color and different from each other when illuminated with a combination of visible light and at least one excitation wavelength; a third ink (23) disposed in a third region of the device laterally offset from the first and second regions of the device, the third ink not emitting light in response to the at least one excitation wavelength, and in the absence of the at least one excitation wavelength, the third ink exhibiting substantially the same non-emissive visible color as the first and second inks when illuminated with visible light; and a fourth ink (24) arranged in a masking pattern, the fourth ink partially overlapping one or more portions of the first ink in the first region and/or the second ink in the second region, the fourth ink not emitting light in response to the at least one excitation wavelength, and in the absence of the at least one excitation wavelength, the fourth ink exhibiting a visible color that is different from the non-emitting visible colors of the first, second, and third inks when illuminated with visible light. In the absence of at least one excitation wavelength, the first, second and third regions together appear as one continuous pattern in a non-luminescent visible color when the security device is illuminated with visible light, while the fourth ink obscures the presence of more than one ink forming the continuous pattern, and when the security device is illuminated with a combination of visible light and at least one excitation wavelength, the first and second regions become visibly distinct from each other and from the remainder of the continuous pattern.)
