Disclosed are methods and systems for validating instruments. For instance, a request to generate a cashier's check may be received from an application executing on a drawer's computing device. Request information may be stored within a data storage entry for the check, and a code to be printed on the check may be generated to include at least a portion of the request information. Instructions may be provided to a printing system to cause the check to be printed with the code, where the printed check is invalid. Instructions may be provided to the application and/or printing system to cause display of a prompt to facilitate a reading of the code to validate the check. When information within the code is read by and received from the printing system, the check may be validated, which triggers a transfer of funds from the drawer's account. Otherwise, the check may remain invalid.

In one embodiment, a secure substrate provides a print-ready surface for printing scratch-off products and eliminates the need to print lower security layers for protecting against attempts to view hidden indicia information. In one embodiment, a secure substrate comprises applying microperforations to a dyed substrate that meets a predefined transmission optical density to resist an attempt to reduce the opacity of the dyed substrate by delamination. In another embodiment, a secure substrate comprises applying a lower opacity layer and a lower background layer on a substrate to provide a secure substrate that meets a predefined transmission optical density. In another embodiment, a secure substrate comprises applying a lower opacity layer on a substrate, applying a reflective coating, and applying a lower background layer over the reflective coating to provide a secure substrate that meets a predefined transmission optical density.

In the field of protection of value documents and value commercial goods, the present disclosure relates to the field of security threads or stripes to be incorporated into or onto security documents, and security documents having security threads or stripes. The security threads or stripes include i) first optically variable layer imparting a first different color impression at different viewing angles, ii) second optically variable layer imparting a second different color impression at different viewing angles, iii) first color constant layer having a color matching color impression of the first or second optically variable layer at a first viewing angle, iv) second color constant layer having a color matching color impression of the first or second optically variable layer at a second viewing angle, and v) a substrate. The layers are jointly visible from one side of the security thread or stripe.

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 aspect of the disclosure relates to a thin film including an amorphous array of particles including a top surface and a bottom surface opposing each other, the thin film exhibiting thin film interference and further coherent scattering from the amorphous array of particles, wherein the thin film may include first regions and second regions, wherein the thin film interference of the second regions may be suppressed as compared to the first regions. Another aspect of the disclosure relates to a product including an indicium including a thin film in accordance with any of the previous claims, wherein the indicium may include an encoded pattern encoded by the relative position of the second regions to the first regions, wherein the encoded pattern may be visible under specular reflection of light of a pre-determined wavelength. Another aspect of the disclosure relates to a method of producing a thin film.
