Regula 4308S is a video spectral comparator intended for advanced authenticity verification of passports, ID cards and other travel documents, as well as visa stamps, seals, driver’s licenses, vehicle registration certificates, signatures, handwriting, paintings, etc. The comparator is designed as a single unit for desktop use. It is used with a built-in PC (it is possible to connect the device to an external PC via USB 3.0) and fully controlled by the Regula Forensic Studio software. The installation of an information reference system is optional. The system of Regula 4308S comprises a 14 MP digital camera with high IR sensitivity, an enhanced optical system, a high-resolution spectrometer, a hyperspectral imaging module, a motorized XY translation stage, an integrated module for reading data from the MRZ, RFID chips, latent images (IPI), 1D and 2D barcodes, integrated modules for 3D visualization and face matching, etc.
EXAMINATION OF MULTI-LEVEL DOCUMENT SECURITY
Advanced document examination under high magnification:
• protection of the document basis:
– paper opacity; watermarks; security fibers; planchettes; security threads and stripes; holograms, kinegrams; foil stamping; pole feature; all types of clear windows, transparent varnish coating, shadow images, etc.
• printing methods:
– intaglio:
texts, guilloche frames, rosettes and vignettes, microprinting, latent images and moire patterns, signs for the visually impaired, blind embossing, color shifting ink, including OVI with embossing and latent-images, etc. – letterpress: serial numbers, texts, barcodes, etc.
– offset printing: including Orlov and rainbow printing
– texts, microprinting, moire patterns, background and anti-copy patterns, etc.
– screen printing: security features with optically variable effects, etc.
– see-through register.
• physicochemical protection: – anti-Stokes luminescence, – UV fluorescence with different wavelengths, – IR luminescence, – security features with magnetic properties, etc.
• 3D visualization (in-built):
– examination of intersecting lines,
– height palette & surface topography.
Additional examinations:
• fragments of document images depending on the degree of absorption or reflection of IR light,
• document alterations such as erasure, etching, etc.,
• traces of signature forgery,
• extraneous lines (do not originally belong to the examined object) that are performed with IR opaque inks,
• blurred, crossed out entries, texts and images,
• document mechanical defects such as cuts, tears, folds, etc.
• and other security features:
– holographic images (OVD),
– blind embossing,
– retroreflective protection,
– security features with IR
-metameric ink,
– special polymer coating of security laminates,
– metallized coating,
– laser engraving on plastic,
– perforation, etc.
