Patent

CA 2151447

Security paper carries an intricate tactile surface profile pattern which has been imparted to the paper during its manufacture, at a stage after initial de-watering but before final drying, by passing the paper through a nip between a forming surface corresponding to the desired pattern and a backing surface. The tactile pattern is of excellent durability, and its intricacy offers a high degree of security. The tactile pattern is visible when viewed under low angle light, which facilitates verification or authentication of security documents made using the patterned paper.
