Document Examination Laboratory

In our Document Examination Laboratory, we employ a meticulous and comprehensive methodology to examine a diverse range of documents with precision.

Our process begins with a thorough visual analysis, where we analyze the paper quality, ink characteristics, and printing techniques used to check whether the suspected document can be analyzed or not.

We can also carry out chemical analysis to decipher the chemical composition of the inks and paper used.

Handwriting analysis is a crucial aspect of our methodology, and we use advanced software to assess individual writing traits and establish authorship.

Additionally, we apply forensic techniques to uncover alterations, erasures, or any signs of tampering within documents.

Our experts are skilled and hold vast experience at examining various types of documents, including contracts, wills, and official certificates.

We implement traditional examining methods along with state-of-the-art technology to ensure the highest level of accuracy in our findings, thereby making us an authoritative resource for legal, forensic, and investigative purposes.

Comparison of Signatures: This involves analyzing a disputed or questioned signature alongside the standard signatures of the individual whose signature needs verification.

Comparison of Handwriting: It involves comparing disputed handwriting to standard handwriting to determine whether both are written by the same suspected individual, establishing authorship.

Document Authentication: It involves detecting any tampering in documents, including changes to content, signatures, or photos on the document, with the intent to alter the original meaning of the documents.

Deciphering of Indented Writings: This involves examining writing left below the original, created by the pressure of the writing instrument. An instrument called ESDA is used to decipher these indentations, and the document is then photographed.

Deciphering Obliterated Writing: This focuses on examining additions or deletions in documents made with correction fluid, tape, or repetitive strokes to conceal the actual writing. A non-destructive examination of obliterated writing is performed, and photography of the revealed writing is done using different light sources.

Examination of the Typewritten Document: This is conducted to identify the typewriter used in creating the document, as each typewriter leaves characteristic marks that distinguish its identity. Further analysis can identify any alterations made to the typewritten document for illegal gains.

Examination of the Sequence of Strokes: When multiple intersecting strokes are observed, this analysis determines the order of strokes to identify whether the writing or letter was produced simultaneously by the same person or later by someone else.

Certificate Verification: This is done to authenticate whether a provided certificate is genuine or fake. Genuine certificates have unique features like serial numbers, QR codes, watermarks, holograms, etc.

Ink Analysis: This examination determines whether the ink used in two writings is the same, establishing whether the same writing instrument was used or if different instruments were involved.

Video Spectral Comparator (VSC-4): This tool consists of various light sources and an adjustable recording device that automatically adapts to different angles and is used to detect inks and dyes present in a document. 

Electrostatic Detection Apparatus (ESDA): It is a device used to decipher indentations in writing that are present on a paper underneath the original sheet, caused by the pressure of the writing instrument. This instrument is non-destructive and highly sensitive in their operation, capable of deciphering content even from indentations that have been present for years. 

Stereo-Microscope: It produces an enlarged view of the exhibit document, which helps in close examination of the minute details of writing and characteristics of the writer.

Miscope: It is a portable microscope with various light sources and is used to decipher the obliterated writing. It includes a camera to capture the results.

Ultra-Violet Lamp: This device comprises a lamp that emits UV light and deciphers faded writing by illuminating the UV region.

DSLR Camera: The camera captures high-resolution images of the exhibits and results for record preservation.

Rofin's Poliray: It is a portable 75W light source, which provides a focused and bright beam, for examining minute handwriting characteristics.

Colour Filters: These are used with the Poliray, to enhance focus on specific colors, either individually or in combination, for better examination.

Scanner: It is used to scan the exhibit (document) at high resolution, for detailed study of document features at high magnification.

Ring Light Illuminators: They are white light illuminators that focus bright light onto the exhibit (documents).

Spherometer: This instrument measures paper thickness, contributing to authentication of documents, especially for multiple page documents.

Grids & Rulers: These are used for marking and measuring document size and handwriting features and are also used during live-size photography.

TLC Kit: This kit comprises TLC chamber, TLC plates, and various chemicals, and is used for ink analysis.
