Patent number: 9747483Abstract: 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.Type: GrantFiled: December 21, 2015Date of Patent: August 29, 2017Assignee: TROY GROUP, INC.Inventors: Brian Lewis, Xiaorong Cai, Michael R. Riley

Publication number: 20170174920Abstract: 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.Type: ApplicationFiled: December 22, 2015Publication date: June 22, 2017Inventors: Xiaorong Cai, Brian Lewis, Chelsea Russell, Michael R. Riley

Patent number: 9534130Abstract: 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.Type: GrantFiled: March 18, 2015Date of Patent: January 3, 2017Assignee: TROY GROUP, INC.Inventors: Xiaorong Cai, Michael R.

Patent number: 9529294Abstract: In accordance with various embodiments of the invention, a method of forming an ultraviolet security toner for use in printing hardware originally designed to use chemically prepared toner includes melt-blending binder resin particles and optionally a charge-control agent, a colorant and a releasing agent. The fluorescent pigment is then admixed to the melt-blended particles to form a fluorescent pre-toner. A first inorganic material is then blended with the fluorescent pre-toner, coating the particles of the fluorescent pre-toner with the first inorganic material. A second inorganic material is then blended with the coated pre-toner, adding another layer of coating to the fluorescent pre-toner. The first inorganic material has an average particle diameter size that is less than the average particle diameter size of the fluorescent pigment particles and the second inorganic material has an average particle diameter size less than that of the first inorganic material.Type: GrantFiled: September 17, 2015Date of Patent: December 27, 2016Assignee: TROY GROUP, INC.Inventors: Kevin L.

Publication number: 20160340531Abstract: An upconverting pigment dispersion includes an upconverting pigment, such as a ?-NaYF4 crystal doped with at least one of Erbium, Ytterbium or Thulium. The upconverting pigment dispersion is aqueous and, thus, includes water. A dispersant is added to increase the stability of the upconverting pigment of the dispersion.Type: ApplicationFiled: December 22, 2015Publication date: November 24, 2016Inventors: Xiaorong Cai, Michael R.

Patent number: 9442402Abstract: A method of making a toner composition including at least one phosphorescent pigment that absorbs energy released by natural or artificial light, and is able to be seen in a dark environment through luminescence of a certain color created by the energy released as light, is described. The phosphorescent toner has a particle size in the range of about 15 to 40 microns, which allows the toner to have the ability to absorb and then release the needed amount of light energy to be noticeable in a dark environment.Type: GrantFiled: May 26, 2015Date of Patent: September 13, 2016Assignee: TROY GROUP, INC.Inventors: Carrie Gilson, Kevin L.

Patent number: 9141009Abstract: A coating composition, system, and method for printing documents that are difficult to chemically or physically forge and that are easy to visually verify are disclosed. The system includes a substrate, a toner, including a colorant and a dye, a primary migration-enhancing coating applied using an offset printing process and optionally a secondary migration-enhancing coating applied using an offset printing process. An image formed using the toner of the invention is readily verified by comparing a colorant-formed image and a dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.Type: GrantFiled: August 18, 2009Date of Patent: September 22, 2015Assignee: TROY GROUP, INC.Inventors: Eugene Hoefs, Michael R.

Patent number: 8817330Abstract: Pantograph background and foreground pairs that perform well in one printer may not perform as well in another. The main problem that occurs is the message is easily seen on the original print. By adjusting the background pattern quality, the pantograph is adjusted for optimal performance for a particular printer. The background pattern is adjusted by first adjusting the pixel density in the background pattern and second, by adding the adjusted cluster background pixel pattern.Type: GrantFiled: April 14, 2010Date of Patent: August 26, 2014Assignee: Troy Group, Inc.Inventors: John E.

Patent number: 8747997Abstract: A coating composition, system, and method for printing documents that are difficult to chemically or physically forge and that are easy to visually verify are disclosed. The system includes a substrate, a toner, including a colorant and a dye, a coating including fluorescent material, e.g., a primary migration-enhancing coating, applied using an offset printing process and optionally a secondary migration-enhancing coating applied using an offset printing process. An image formed using the toner of the invention is readily verified by comparing a colorant-formed image and a dye-formed image and/or to a reverse negative imaged formed by the dye quenching the fluorescent material. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.Type: GrantFiled: October 18, 2010Date of Patent: June 10, 2014Assignee: Troy Group, Inc.Inventors: Kevin L. Heilman, Eugene Hoefs, Michael R. Riley

Patent number: 8405882Abstract: The invention relates to a method for devising a pantograph. The method includes the steps of defining a message to be displayed on the pantograph, forming a background pixel format and a foreground pixel cluster pattern. The foreground cluster pattern is devised from the background pixel formation. Adjacent pixels in the background pattern are combined to form pixel clusters. The foreground pattern of pixel clusters is used to fill the characters of a pantograph message.Type: GrantFiled: December 15, 2009Date of Patent: March 26, 2013Assignee: Troy Group, Inc.Inventors: John E.

Patent number: 7842445Abstract: A toner for printing documents that are difficult to chemically or physically forge and that are readily easy to visually verify and methods of using and forming the toner are disclosed. The toner includes a colorant for printing an image on a surface of a document, a fluorescent pigment that under normal lighting is masked by the colorant but creates a visible image on the first surface of the a substrate when irradiated by black or ultra-violet light, and a dye for forming a latent version of the image underneath a surface of a substrate. An image formed using the toner of the invention is readily verified by comparing the colorant-formed image and the dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.Type: GrantFiled: April 26, 2007Date of Patent: November 30, 2010Assignee: Troy Group, Inc.Inventors: Michael R.
