Abstract: Method of making color changing inkjet inks for security printing applications use photochromic materials that cause the inkjet ink to print marks that are colorless under ambient light and appear in a color when exposed to sunlight or UV light (covert). In another embodiment, the printed mark appears in a first color under ambient light, and changes to a second color when exposed to sunlight or UV light (overt). The methods of making the photochromic inks produce ink components that are stable and maintain their color changing capability for the shelf life of the printed material. The inkjet ink formulations are suitable for use on porous and non-porous surfaces, such as plain paper, coated paper, Teslin, polymer film, ceramic or metal, for example.

Abstract: A means and method to enhance the security of personalized and variable print-on-demand data on vital records or documents, such as checks, by inkjet printing. A specially formulated penetrating ink prints information on the front side to create an indelibly seamless “dual image” on the reverse side. The reverse image symbiotically complements the primary image on the print side to provide ease of authentication and tamper resistance. Specially formulated MICR ink is used to print information on the front side. Specially formulated penetrating may be different color. Either invisible ultraviolet fluorescent penetrating ink or visible penetrating ink may be used to create the image on the reverse side. The print side and reverse side are printed using single-pen printing by orienting inkjet two different pens in a series.

Abstract: High security inkjet inks are made my milling two or more functional materials, such as invisible ultraviolet fluorescent dyes or pigments, infrared Anti Stokes upconverting pigments, infrared absorption and fluorescent dyes or pigments and iron oxide magnetic pigments, into a pigment dispersion. A wet media mill is used to mill the pigment dispersion until the average particle size is below 300 nm. The dispersion is combined with main components of an inkjet ink, such as deionized water, humectants, surfactants, polymer resin and biocides, to produce the high security inkjet ink.

Abstract: A method for creating a secure document, registering the secure document and verifying the authenticity of the secure document includes receiving a print object that has content. A security feature, including an identifier, is created and is associated with the content. The identifier may be a barcode. The barcode may represent a character string. The security feature may include the identifier barcode and a decoy barcode that is not associated with the content. The identifier barcode (or the character string represented by the barcode) and the content are transmitted to a database for storage. Once stored, the identifier and the content are considered to be registered. A print object that includes the security feature and the content is then transmitted to a printer for printing.

Abstract: An upconverting pigment dispersion includes an upconverting pigment, such as a β-NaYF4 crystal doped with at least one of Erbium, Ytterbium or Thulium. The upconverting pigment dispersion is aqueous. Upconverting inkjet ink is made by mixing the crystals with a polymer dispersant and water and milling the mixture until the crystal particles are between 50 nanometers and 200 nanometers. Deionized water, a colorant and a humectant are added to the milled mixture.

Abstract: A secure document includes a fluorescent barcode and a fluorescent filler printed onto a substrate. The fluorescent barcode is printed using a first fluorescent ink of a first color and the fluorescent filler is printed using a second fluorescent ink of a second color that is different than the first color. In order to read the fluorescent barcode, the secure document must be illuminated with ultraviolet and/or infrared light. Then, a color filter must be used to filter the fluorescent filler out, leaving the fluorescent barcode visible.
