Security papers

Security fibers are embedded in the paper during manufacture and are non-reproducible.

Cascades security fibers are available in a range of colors and shapes. We recommend combining more than one:

• Invisible fluorescent fibers

  become visible under ultraviolet light (3 mm, 5 mm or 6 mm in length).

• Invisible fluorescent microfibers

  become visible under ultraviolet light (0.375 mm in length).

• Visible fluorescent fibers

  change color under ultraviolet light and can be used in combination with non-fluorescent fibers (3 mm or 5 mm in length).

• Visible fluorescent microfibers

  change color under ultraviolet light and can be used in combination with non-fluorescent fibers (0.750 mm in length).
