irisafe 124x300 Fortress Paper’s Irisafe

An example of what Irisafe looks like when copied. Not so brilliant.


With counterfeit banknotes, ID papers, and open-air admission tickets becoming increasingly easier to produce and more frequent due to technological advances in scanning and colour printing, the need for security papers that can’t be copied is on the rise.

In response to this demand, Fortress Paper has developed Irisafe – a security feature that cannot be duplicated by colour copiers or scanners.

Irisafe is an iridescent striped coating that is integrated into security papers and is characterized by brilliant and changing colours when you change the angle of view.

If an Irisafe stripe were present in a $20 bill, for example, the radiant colours on the stripe would change when you moved the bill at various angles – easily visible to anyone, even in less than optimum light conditions.

To further enhance the security feature, more than one stripe can be used on the same security paper.

By placing two or three different coloured iridescent stripes next to each other, the colour change between the different stripes is amplified and intensified to the naked eye when the angle is changed.

A colour copier cannot reproduce either the brilliancy or the change of colour. At best, a photocopied forgery will show spotty stripes instead of the trademarked Irisafe qualities.

On top of all this, various machine-readable invisible tracer substances and pigments can also be integrated into the stripes, further increasing the safety provided by Irisafe.
