Provided is a production method of a sheet member, including a process of forming, by printing, a phosphorescent layer containing a phosphorescent material on a surface of a sheet-shaped substrate with a transmissive property, and a process of forming a reflection layer, by printing, including a reflective material to reflect light on a surface of at least either one of the substrate or the phosphorescent layer in such a manner that the reflection layer overlaps at least a part of the phosphorescent layer in a thickness direction of the substrate.

Techniques for manufacturing a light field print using a printing press. The techniques include: identifying at least one characteristic of the printing press at least in part by printing at least one calibration pattern; obtaining content to be rendered using the light field print, the content comprising multiple scene views; generating, based at least in part on the content and the at least one characteristic of the printing press, a front target pattern and a back target pattern; and using the printing press to: print the front target pattern on a first side of a substrate; and print the back target pattern on a second side of the substrate.

A method of printing a stealth white image includes applying a stealth ink containing a red coloring material that emits visible light at exposure to ultraviolet radiation and a green coloring material that emits visible light at exposure to ultraviolet radiation to a substrate which contains a fluorescent brightener to form the stealth white image thereon, wherein the stealth white image demonstrates an a* value of from −2.0 to 2.0 and a b* value of from −10.0 to 0 at exposure to ultraviolet radiation having a wavelength of 370 nm according to CIE 1976 L*a*b* colorimetric system.

A printed object includes a substrate and a first information code disposed on the substrate, wherein: the first information code is constituted of an infrared ray-absorptive ink layer that has been printed with an infrared ray absorptive ink; and the infrared ray absorptive ink layer is configured such that, when a laminated body constituted of a test substrate made of the same material as that of the substrate, and a test infrared absorptive ink layer made of the same material as that of the infrared ray absorptive ink layer and disposed on the test substrate is subjected to a relative spectral reflectivity measurement on the test infrared ray absorptive ink layer side, with the test substrate as the reference (100% reflectivity), the minimum relative reflectivity in the visible region is 50% or higher, and the minimum relative reflectivity in the infrared region is 75% or lower.

The present invention relates to a new crystal form of the compound of formula and a process for its preparation. The compound may be used in compositions for inks, paints and plastics, especially in a wide variety of printing systems and is particularly well-suited for security applications.

The present invention relates to a novel identification label that can be customized. The labels are designed to be either integrated or removably attached on exterior surface of consumer product containers allowing users to avoid potential confusion with respect to ownership, use or control of their containers. The label has an opaque scratch-off blank surface that can be removed to create a personalized identification mark. The label may have an UV-ink coating or can have a label layer for creating identification mark when the scratch-off blank surface is scratched. The labels are designed to be affixed on any personal item to prevent items from accidentally being misidentified.

A digitally printed security document includes: a security document substrate; a first digitally printed print working on a first surface of the substrate in a first region, the first print working including a first array of printed elements arranged according to a first grid of lattice points having a first pitch; and a second digitally printed print working on the first surface of the substrate in a second region, the second print working including a second array of printed elements arranged across a second grid of lattice points having a second pitch different from the first pitch.

A system for printing documents and anti-forgery security papers especially banknotes is provided. The system includes a mechanical feeding mechanism, a hologram pattern print section, an invisible, fluorescence color and main colors pattern printing section using at least three units of ink jet, a varnish coating section, a rotating cylindrical silkscreen printing section for optical variable ink (OVI), a raised printing section, a delivery section, a paper and handle receiving section and a central computer control section. The system has been introduced to create various security features in securities wherein all of the processes including the raised printing are introduced in an all-in-on device.

An example container includes: structure having an interior and an exterior. The interior is to contain an electronic product. The exterior comprises: a first label of a first type of polychromatic ink to be activated at a first wavelength; and a second label of a second type of polychromatic ink to be activated at a second wavelength different from the first wavelength; the first label to indicate a first set of features to be configured at the electronic product using a first wireless signal; and the second label to indicate a second set of features to be configured at the electronic product using a second wireless signal. The structure is transparent to the first wireless signal and the second wireless signal.

Embodiments include luminescent phosphor compounds that include one or more emitting ions and one or more disturbing ions, and methods for their production. An emitting ion in the compound may be characterized by a first decay time constant when the emitting ion is undisturbed. However, a corresponding disturbing ion in the compound, which is different from the emitting ion, causes the emitting ion to have a pre-defined, target disturbed decay time constant that is greater than zero and less than the first decay time constant. An embodiment of an authentication system is configured to measure the decay time constant of a phosphor compound applied to an article, and to determine whether the decay time constant corresponds to a phosphor compound that includes a particular disturbing ion (e.g., in order to determine whether or not the article is authentic).
