The disclosure discloses methods and systems for securing confidential content of a document while printing and/or while reproducing the document. The method includes identifying confidential content in a document. Upon identification, the confidential content is encoded based on one or more encoding algorithms. Then, coordinate information about the confidential content is identified. The method generates a pre-defined code such as a QR code having authorized user information, prints the IR security mark and pre-defined code on the document. The printed document includes the confidential content in an encoded format, the IR security mark with the coordinate information of the confidential content and the pre-defined code including the authorized user information. At the time of reproducing, the method includes checking if a user who is requesting for reproducing the printed document is an authorized user. Based on the check, the user is allowed to reproduce the printed document.

A deposition device may deposit, on a substrate, a binder layer that includes a first set of magnetic flakes and a second set of magnetic flakes and may cause, when a temperature of the binder layer satisfies a temperature threshold (e.g., a Curie temperature of the first set of magnetic flakes), a magnetic field to be applied to the binder layer to cause the first set of magnetic flakes and the second set of magnetic flakes to be oriented according to the magnetic field. The deposition device may cause, when the temperature of the binder layer ceases to satisfy the temperature threshold, another magnetic field to be applied to the binder layer to cause only the second set of magnetic flakes to be oriented according to the other magnetic field.

The present invention relates to compositions, comprising silver nanoplatelets, wherein the silver nanoplatelets are capped by a compound of formula (XX), wherein R41 is a C4-C25alkyl group, which may be interrupted by one, or more oxygen atoms, and n is a number 1 to 10, especially 1 to 4, very especially 1, or 2, a process for its production, printing inks containing the compositions and their use in security products. The capping with the compound of formula (XX) renders the surface on the nanoparticles more hydrophobic, while maintaining colloidal stability of their dispersions in organic solvents and/or monomer compositions. This combination of properties allows for production of stable UV curable coating/printing compositions, suitable for manufacture of dichroic security elements for protection of value documents. The surface modification, described in the present invention is suitable for silver nanoplatelets of different sizes and, correspondingly, colors, and is especially useful for manufacture of solvent-free coating, or printing compositions.
