DORS 30 has self-contained power supply and
designed for visual authenticity control of presence and
location of protective elements made by magnetic inks on all
world banknotes, securities and security printing documents,
which makes it ideal portable device.
MAGNETOOPTICAL VISUALIZATION
Magnetic inks use is a widespread security feature
applied on world’s banknotes and other security printing
documents. Magnetic properties of these inks are guaranteed
by included ferromagnetic additives.
Magnetic security thread on Euro
Magnetic marks are used for printing special marks, serial
numbers, lettering and image fragments, e.g. security thread
on Euro banknotes has magnetic properties guaranteed by
including ferromagnetic.
US Dollar magnetic relief
Magnetic inks visualizing DORS 30 is
performed with the help of special sensitive element -
magneto-optical crystal.
User places DORS 30 on
the verified object, switches the built-in lighting and
views through the ocular lens the image fragment under the
magneto-optical crystal. The image made by ferromagnetic
inks acquires clear cut edges, becomes three-dimensional and
relief.
Due to the DORS 30
tenfold optical magnification system, user gets the
