    摘要： Methods and systems for creating optical effects in pigment, inks, and on media are described. There is in particular described a system or indicia for use as a security or identification feature comprising a material that is capable of inducing a change of optical appearance of the system or indicia in response to exposure to illumination at different excitation intensities, wherein exposure of the material to illumination at a high excitation intensity causes the system or indicia to radiate a first emission spectrum with a first color spectrum, and wherein exposure of the material to illumination at a low excitation intensity causes the system or indicia to radiate a second emission spectrum with a second color spectrum that is distinct from the first color spectrum.

    摘要： Methods and systems for creating optical effects in pigment, inks, and on media are described. There is in particular described an object comprising a substrate and an indicia comprising a first material and a second material, wherein the first material is coupled to the substrate, the first material having a first optical appearance without ultraviolet (UV) excitation and a second optical appearance after receiving UV excitation, wherein the second material is coupled to the substrate and is capable of providing a color, and wherein the indicia appears to radiate and/or reflect a first color upon initial UV excitation while the first material has the first optical appearance and then appears to radiate and/or reflect a second color upon continued UV excitation as the first material has changed to the second optical appearance

    摘要： A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.

    摘要： A method of embedding an optical signature in a document and document produced therefrom. The optical signature is an optical pattern generated from a known value, such as a mathematical, geometric, trigonometric, size, phase, and the like, and the same value can be generated from examination of a document having the embedded optical pattern. The document can be validated, authenticated, or the determination of a valid copy of an original document with the embedded optical signature made through comparison of the known value and the value generated from the optical pattern on the document. The optical pattern can also be generated from other identification codes on the document.

    摘要： An image reading device includes: a conveying unit for conveying an irradiated member that has a hologram area in a conveying direction; a first light source for applying light to an irradiated part in the hologram area; and a second light source separated from the first light source along the conveying direction and applying light to an irradiated part in the hologram area when the hologram area is conveyed by a prescribed distance. An irradiation angle at which the irradiated part is irradiated with the light of the first light source is made to be different from an irradiation angle at which the irradiated part is irradiated with the light of the second light source when the hologram part is conveyed by the prescribed distance. Lights reflected by the hologram area are respectively received to detect an electric signal of the hologram area of the irradiated member.
