    • There is described a printed security feature (1) provided onto a printable substrate, which security feature includes a printed area (100) consisting of a multiplicity of adjacent rectilinear and/or curvilinear elements (110, 120) printed with a given spatial frequency. The rectilinear and/or curvilinear elements are printed with at least first and second inks which exhibit the same or substantially the same optical appearance when illuminated with visible white light, such that the security feature produces a first graphical representation when illuminated with visible white light, at least the first ink being an ink which responds to non-visible light excitation by producing a characteristic optical response differentiating the first ink from the second ink. The security feature produces a second graphical representation when illuminated with non-visible light, which second graphical representation exhibits a distinctive two-dimensional graphic element (B) which is revealed only when the security feature is illuminated with non-visible light. Inside boundaries (160) of the distinctive two-dimensional graphic element, a part (P3) of the rectilinear and/or curvilinear elements is printed with a combination of the first and second inks, the rectilinear and/or curvilinear elements being subdivided, within that part, into first and second juxtaposed sections (110a, 110b, 120a, 120b) which are respectively printed with the first ink and with the second ink. Outside the boundaries of the distinctive two-dimensional graphic element, portions (P1, P2) of the rectilinear and/or curvilinear elements are printed with only one of the at least first and second inks. The at least first and second inks are printed in register one with respect to the other so that the boundaries of the distinctive two-dimensional graphic element are not visible when the security feature is illuminated with visible white light and the distinctive two-dimensional graphic element only becomes visible when the security feature is illuminated with non-visible light.

    • This invention provides a latent image pattern formed body that allows to observe a latent image having excellent visibility and authenticity discrimination and design properties than those of related arts when observed from the oblique direction. The latent image pattern formed body includes, in at least part of one surface of a substrate, a latent image region, an outline region arranged on an outline of at least part of the latent image region, and a background region arranged on a background of the latent image region and the outline region. In the latent image region, a plurality of first elements having a concave or convex shape are arranged at a first pitch in a first direction. In the background region, the plurality of first elements are arranged at the first pitch in the first direction in a phase different from that of the first elements in the latent image region. In the outline region, the plurality of first elements are arranged at the first pitch in the first direction in a phase different from that of the first elements in the latent image region or background region adjacent to the outline region. In the latent image region, the background region, and the outline region, a plurality of second elements having a color different from that of the substrate are arranged at a second pitch in a second direction.
    • 本发明提供了一种潜像图案形成体,当从倾斜方向观察时,能够观察到具有优异的可视性和真实性鉴别和设计特性的潜像。 潜像图案形成体在基板的一个表面的至少一部分中包括潜像区域,布置在潜像区域的至少一部分的轮廓上的轮廓区域和布置在潜像图像的背景上的背景区域 潜像区域和轮廓区域。 在潜像区域中,具有凹凸形状的多个第一元件在第一方向上以第一间距排列。 在背景区域中,多个第一元件以与潜像区域中的第一元件不同的相位在第一方向上以第一间距排列。 在轮廓区域中,多个第一元件在第一方向上以与潜像图像区域或与轮廓区域相邻的背景区域中的第一元素的相位不同的相位排列。 在潜像区域,背景区域和轮廓区域中,具有与基板不同的颜色的多个第二元件以第二方向以第二方向排列。
