摘要： 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.

摘要： An aqueous penetrating ink includes a pigment and a water-soluble dye. The ink also includes a humectant in which the water-soluble dye is to be at least partially dissolved. The humectant is present in the ink between 20 percent by weight and 70 percent by weight. This amount of humectant results in a slow evaporation rate. The ink also includes water, making it suitable for use with some inkjet printers. Because the pigment is not dissolved in the humectant or the water, it forms an image on the surface of a printed side of a substrate. The slow evaporation rate of the humectant allows it to carry the ink through a thickness of a substrate so that it is visible on a non-printed side of the substrate.

摘要： 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.

摘要： 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.

摘要： An aqueous MICR inkjet ink includes between 20% to 60% by weight of a magnetic iron oxide with cobalt doping, pigment dispersion, mixed with between 5% to 30% by weight of a humectant, in a water solution emulsion. The dispersion is milled in a wet media mill to obtain particle size in the 150 nm range. Additional humectant, surfactants, jetting agents, and stabilizing additives are added for the final ink composition.

摘要： 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.
