Security Paper Is Our Specialty
At Simpson Security Papers, Inc. security has been our specialty since our process was first developed in 1871. We have incorporated that knowledge with leading-edge technology to provide the ideal product for your company’s needs. We manufacture a variety of high quality safety, security, and check paper products including our well-known Basketweave® pattern.
George LaMonte & Sons began designing check paper in 1871 using the now-patented LaMonte process. The security features he developed back then still form the basis for our current security papers. Since then we have provided increasingly sophisticated security features that have successfully deterred forgery and counterfeiting advancements.
