20150092248 | Computer-Based System and Method for Adding Variable Security Data in Printing Operations - A computer-based method and a system for adding and printing variable security data. The system includes a memory, a processor, and a printer. The memory stores received print data. The processor modifies the print data for adding variable security print data and sends the modified print data for printing. The printer receives and prints the modified print data. The variable security data may vary between different printing operations. The processor captures a portion of the stored print data based on data-capturing criteria and modifies the stored print data based on the captured portion of the stored print data. The data-capturing criteria may be user-defined and may include leading tag data, trailing tag data, matching tag data, or combinations thereof for indicating a relative position of the captured data. | 04-02-2015 |
20140293357 | Method of Generating Void Pantographs - A method of generating a large number of different void pantographs quickly and easily enables selecting a void pantograph that works best with a particular copy machine make and model. The background patterns are generated by varying the size of the dots and placement of the dots on an X-Y grid. The foreground pattern is generated by varying the size of the dots and placement of the dots on an X-Y grid. The foreground and background patterns may be generated by combining two separate patterns. A foreground pattern is combined with multiple background patterns to produce the different void pantographs. A full page of void pantographs having a similar density is tested on a copy machine to determine which one works the best. | 10-02-2014 |
20130280648 | PHOSPHORESCENT TONER AND METHODS OF FORMING AND USING THE SAME - 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, and a method of forming and using the toner are described. The phosphorescent toner has a particle size in the range of about 15-40 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. | 10-24-2013 |
20120171603 | COATING COMPOSITION INCLUDING FLUORESCENT MATERIAL FOR PRODUCING SECURE IMAGES - 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. | 07-05-2012 |
20100278544 | SYSTEM AND METHOD FOR ENSURING THAT ONLY A SPECIFIC TONER IS USED FOR PRINTING A DOCUMENT - The present invention relates to a system and method for ensuring that a correct toner is used for printing a document. A printer receives data about a document requiring a specific toner type to print the document. The printer receives toner type identification from a toner cartridge inserted into the printer. The specific toner type required is compared with the available toner type in the cartridge. If the available toner type in the cartridge matches the specific toner type, the document is printed. If there is no match, the printer displays an error message and does not print the document. | 11-04-2010 |
20100259792 | METHOD FOR ADJUSTING QUALITY OF A PANTOGRAPH BACKGROUND PATTERN - 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. | 10-14-2010 |
20100159137 | COATING COMPOSITION, SYSTEM INCLUDING THE COATING COMPOSITION, AND METHOD FOR SECURE IMAGES - 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. | 06-24-2010 |
20100157378 | METHOD AND APPARATUS FOR SECURE DOCUMENT PRINTING - 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. | 06-24-2010 |
