1. A method of producing a document for use as a negotiable instrument having enhanced security against counterfeiting comprising the steps of:
- providing a document for use as a negotiable instrument, said substrate having a clear band extending along a bottom edge of said document, said clear band having a depth of at least 5/8'"'"', said clear band being divided into at least three information fields, whereby a first transit-number field is adapted to receive magnetic information describing routing information for electronic processing of said document, a second on-us field is adapted to receive magnetic information describing account information, and a third amount field is adapted to receive magnetic information describing said specified amount;
forming a three dimensional light diffracting image on an optical strip;
continuously rolling said strip onto a surface of said document from a top edge to said bottom edge, wherein said strip is affixed to said surface of said document;
printing on said surface of said document, wherein a printed image overlies a common portion of said surface with said strip, said image extending beyond a boundary of said strip onto an additional portion of said surface of said document.

Abstract
A method of making a document, such as a check or stock certificate, having enhanced security against counterfeiting. The document includes a strip of foil having a three dimensional light diffracting image thereon affixed to the document. The strip of foil may be affixed to the document before or after the background printing or face printing of the document is completed. In this manner, the light diffracting strip may be printed on by the background and face printing of the document as desired.

9. A method of producing a check having enhanced security against counterfeiting comprising the steps of:
-
providing a substrate, said substrate having a clear band extending along a bottom edge of said document, said clear band having a depth of at least 5/8", said clear band being divided into at least three information fields, whereby a first transit-number field is adapted to receive information describing a routing information for electronic processing of said document, a second on-us field is adapted to receive information describing account information, and a third amount field is adapted to receive information describing said specified amount; forming a three dimensional light diffracting image on an optical strip; printing magnetic information onto at least a portion of said clear band; and continuously rolling said strip onto said surface of said check base wherein said strip is affixed to said surface of said check base, said strip being positioned to extend from a top edge of the check to a bottom edge of the check and through said clear band. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of producing a check having enhanced security against counterfeiting comprising the steps of:
-
providing a substrate adapted for use as a check, said substrate having a clear band extending along a bottom edge of said document, said clear band having a depth of at least 5/8", said clear band being divided into at least three information fields, whereby a first transit-number field is adapted to receive magnetic information describing routing information for electronic processing of said document, a second on-us field is adapted to receive magnetic information describing account information, and a third amount field is adapted to receive magnetic information describing said specified amount; forming a three dimensional light diffracting image on an optical strip; continuously rolling said strip onto a surface of said check wherein said strip is affixed to said surface of said check, said strip being positioned to extend from a top edge of the check to a bottom edge of the check and through a portion of said clear band; and printing an image onto said surface of said check, wherein a first portion of said image is printed on said strip, and a second portion of said image is printed on said surface of said check. - View Dependent Claims (16, 17, 18, 19, 20)
