Safety Features

 

For security features we talk about:

Stitch low pressure
Water-marks
Security thread
Examination register
Folios patrols or folios elements, both provided with a hologram
Pearlescent strips or optically variables colors
Microwritings
Fluorescent printing inks and fluorescent fibres in the paper
Infrared characteristic feature

These characteristic features must not have been applied with every bank note at the same moment,
it often depends also on the value (purchasing power) of the bank note, because the application also causes expenses.
Only once I wanted to have named all different security characteristic features.
