AB8000 is an extremely accurate measuring system for analysis of handwriting stroke pressure. By measuring the progression of the pressure, measured by the indentation of the writing instrument in any stroke or signature, the software displays a unique curve of the indentation on the paper created by the writer's pressure distributed along the lines of the stokes. While a high level forgery may duplicate letter shape and line thickness, it would be extremely difficult to duplicate pressure curves and shape. By comparing the curves of a genuine signature with a questioned signature, these indentation curves are very useful for  document examiners to determine if the questioned signature is genuine or counterfeit. The technology is a very useful tool for handwriting analysis, particularly for difficult signatures - those with fewer strokes, or signatures of high level forgery.

Key features

Measures the dynamic development of handwriting

By comparing the curves of a genuine signature with a questioned signature, The examiner is able to examine the pressure distribution of the writing instrument along the strokes, which provides a high level of discrimination between any individual's natural writing characteristics and forged writing, particularly with regard to signatures.  The system can then calculate a correlation factor.

Methodology

-Variable focus microscopy

- Dark field long range ring light

-Extremely flat document plate with Vacuum system with more than 4000 evenly distributed low profile holes 

-A 250x300 mm motorized XY axis system moves the microscope across the document with precision and speed.

-3D-topography calculations measure multiple indentation points.

- Exmor camera with 6 million pixels

Integrated Imaging Platform

The system is enclosed in a large aluminum enclosure with all connectors located in the back (power and two USB ports). 

Software

Easily accessible software allows for control of imaging cameras, 3D indentation measurement, system hardware, processing of dynamic curves and correlation factors.

Extreme Precision

The AB8000 can measure the signature indentations to a resolution of 1 micron. The system can also measure the height of ink print from laser printers and highlight irregularities to facilitate with discrimination of print unique to individual printer hardware, even of the same.
