Security papers

Embedded during papermaking, security planchettes are tiny dots only 0.158 cm in diameter. Planchettes are non-reproducible because they are embedded randomly in the paper. This feature gives instant validation by removing them from the paper.

They protect your documents when used alone or in combination:

• Fluorescent planchettes

  change color under ultraviolet light.

• Non-fluorescent planchettes

  can be removed from the paper surface, thereby authenticating a document.

• Chemically reactive planchettes

  change color (from yellow to red) upon contact with an alkaline solution.

• Thermochromic planchettes

  are authenticated through contact with heat, which causes them to change color. It's therefore possible to verify a document without the aid of special lamps or tools.
