The manufacturing of security document paper represented a core business activity at Stowford Paper Mill. This was particularly so in the latter decades, where it represented around half of the product portfolio, with the mill recognised as a world leading supplier.
Security papers can be categorised as any document designed to deter fraudulent activity, the illicit alteration of a genuine document, or combat counterfeit activity, the illicit reproduction of a document to pass as a genuine one, (a fake), by the incorporation of special features.
Protecting documents from fraud can be tackled in several ways, often in a complementary approach between paper manufacturer and security printer. As fraud commonly entails the removal or alteration of print or pen ink, such as the amount on a cheque or perhaps attained grades on an exam certificate, the paper must incorporate features that demonstrate tamper evidence. To combat counterfeiting, the paper must incorporate features that can serve to identify or authenticate that a document is an original.
