Standard Register Awarded Patent for Document Security Feature

Standard Register, Dayton, Ohio, has been awarded a patent for a chemically reactive security ink that helps mitigate or reveal certain types of document fraud by preventing the chemical alteration or "washing" of secure documents.

The chemically reactive ink masks a warning word or message printed on secure documents. When a check, receipt, label or other item is chemically altered or "washed," the special ink is removed to reveal a hidden word or message. The reactive security ink deters individuals from altering the dollar amount on checks, cash receipts and other secure documents, which could previously be accomplished by erasing portions of text using common household chemicals such as acetone found in nail polish remover.
