LogoDots replace conventional halftone dots to add security to any document
U.S. Patent No. 7,196,822 - Amgraf’s Patented Graphical Security Document Technology

Capture any image such as a corporate logo, a photograph, or a key word or phrase, and convert that image into a LogoDot halftone dot that replaces conventional round dots typically used in traditional printing. When compared to conventional halftone dots, LogoDots are much more difficult to faithfully reproduce with commercial photocopiers and scanners, resulting in easily detectable copies. Contact Amgraf to request a free sample kit containing examples of documents protected by LogoDot technology.
