Advanced Examination of Magnetic Security Features
Regula 7701M is designed for carrying out non-destructive examinations of large documents (up to 335×297 mm) with magnetic properties.
The wide functionality of the device includes construction and comparative analysis of the magnetic patterns of examined documents, detection of the magnetic properties of dyes, examination of magnetic security features, reading of invisible magnetic strokes and codes, examination of damaged documents – reading of blurred and crossed out texts printed with magnetic ink, and assessment of the magnetic parameters of document security features: distribution of magnetic induction and magnetic flux modulus.
In addition, Regula 7701М provides the possibility to carry out a comparative assessment of the magnetic properties of document protection elements. The Magnetic Measurements function in Regula 7701M makes it possible not only to obtain a histogram of the normal component of magnetic induction Bn (in Tesla) for a frame and to calculate the module of the magnetic flux Фn (in Weber) in that frame area, but also to compare the distance (d) between the histogram of an examined document and that of a sample. Comparing the obtained parameters (Bn, Фn, d) of the examined document and the sample makes it possible to draw a conclusion as to the authenticity of the document and the degree of damage and/or wear to the magnetic image.
The device can be supplied together with the demagnetizer Regula 7751, which is intended to improve the accuracy of magnetic parameter measurements.
Regula 7701M is controlled via CADR software, which can capture, process, and store images of examined objects.
