| 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 |
