ODT Security Pantographs: Optical deterrent technology uses a patented security screen that discourages attempts to duplicate secure documents on copiers or scanners. It works in the same way that a void pantograph works in that when photocopied, the word "VOID" appears. The differences are that ODT works effectively when copied by most any black and white copier, color copier or scanner, and it does not have to be used with a pantograph background screen. Not having to use a pantograph screen to hide the void in the background allows for a cleaner looking document and allows for better legibility on documents that are text intensive. The ODT technology works well on checks, prescription blanks, transcripts, medical records, wills and other documents needing that extra security applied to them. |
