Abstract
A process is disclosed for printing a document such as a negotiable instrument in a first and a second color for increasing the security of the document. A major portion of the document is printed with a first information in a first color from a first printer. A second information is created from at least a portion of the first information for proving a security pattern. The security pattern is printed over a minor portion of the document in the second color from a second printer to increase the security of the document. The process may be used for printing a check in a magnetically readable first color and a non-magnetically readable second color including colors having a color spectrum located outside of the color spectrum range of a conventional color photocopier.
