Security features for forgery-proof plastic cards
Guilloche print (security pattern)
This security pattern was previously used to make banknotes counterfeit-proof and is still a popular security feature today. The guilloche pattern consists of several interwoven and overlapping lines. The individual lines form cord-like, often asymmetrical ellipses. This pattern can hardly be copied, making it more difficult to fake maps.
Microscript
Micro-typefaces can only be produced with special modern printing processes and can not be copied by normal printing presses. The micro-typeface becomes legible only with the help of a magnifying glass. Micro-typefaces are used primarily for sensitive printed matter such as passports, banknotes or security cards.
UV-fluorescent colors
An imprint with UV colors only becomes visible under special black light. The particles contained in the ink are charged with light and are then seen under a black light lamp. Even the imprint of UV fluorescent colors makes the falsification of ID cards and other cards more difficult.
Iriodin print / tilt effect color
Iriodin colors change their color depending on the viewing angle. They are also referred to as tilt effect colors and are known from banknotes production. Even banknotes are often protected against counterfeiters with this technique.
