Typewritten Document Examination by Forensic Document Examiners

Typewritten documents can serve as crucial evidence in legal and investigative processes, whether in fraud cases, forgery claims, or disputes over wills. Forensic document examiners (FDEs) are specifically responsible for investigating the validity of these documents. This blog post explores the step-by-step process FDEs use to validate typewritten documents, from identifying typewriter models to analyzing potential alterations.


The Role of Forensic Document Examiners in Typewritten Document Analysis

Forensic document examiners are typically very experienced and skilled analysts whose work involves determining if a specific document has been forged, altered, or is authentic. In cases involving typical typed documents, they pay attention to the make of typewriter used and the quality of inked print, as well as any wiping or erasure marks. Although questionable at first, FDEs can, after careful analysis, conclude whether a document was produced on a particular typewriter, which can help police investigations.


Steps in the Validation of Typewritten Documents

Validation of typed documents is one of the areas of concern in forensic document examination. It involves a number of procedures, and the validation of typed documents is composed of several steps.

Various stages in the process of validation of typewritten documents assist the examiners to come up with grounds for or against the authenticity of the document.


Identifying the Typewriter Model and Year of Manufacture

The first step towards processing a typewritten document is to identify the make of typewriter that the document was produced by and the date it was manufactured. Features like the type of font preferred, the position of letters on the typewriter, and the amount of space between the letters normally differ from one typewriter model to the other. Forensic examiners collect vast information from extensive databases of typewriter models to help in identification of the make and model.

Due to the unique typeface and print characteristics produced on each make and model of a typewriter, FDEs can trace whether or not the typewriter that made that document was available when the document was supposed to have been typed. It’s when there are disparities in the dates that there is a likelihood that the document has been forged.


Exploring Type Face and Print Features

Every typewriter has its own unique features in the typed documents they produce because of variation in style of typeface, positioning of the letters, and wear and tear on the typewriter. Examiners analyze the following elements:

Font Style: Every typewriter model has its own type, and some of the fonts are available just for one model of typewriter.

Letter Shapes and Sizes: Slightly different shapes, sizes, and locations of the letters are useful in identifying the different models of typewriters.

Ink Patterns: The distribution and thickness of the ink deposited at the papers of a specific typewriter are specific to this typewriter as they gradually wear out.

When studying all these aspects, the examiner is able to determine which typewriter has most likely been used and whether it is possible that the document in question could have been prepared on this particular model.


Analyzing Spacing and Alignment

If spacing and alignment techniques are to be analyzed then spacing refers to the amount of space that is found between individual letters or groups of letters in a passage of text. Most original typewriter models contain tiny mechanical inaccuracies as to the appearance of letters and the arrangements of words in text. Examiners look for:

Character Spacing: Micro variations in the distance between the letters or words suggest the general traits of a certain typewriter model.

Vertical Alignment: As with any mechanical item that gets used for extended periods, some typewriter keys produce letters that are slightly higher or lower than others. It becomes a characteristic feature that the vertical misalignment can take place.

Line and Margin Irregularities: Modern typewriters, unlike current printers, are not able to offer straight, neat, and identical margins, and so examiners will check margins, spacings, and any slope noticeable in alignment.

Spacing and alignment inconsistencies can serve as "fingerprints” for a specific machine, helping to validate whether the document was produced on the claimed typewriter.


Detecting Signs of Tampering or Alterations

Another major consideration when examining documents for purposes of forensic document examination is ascertaining if any offensive alterations were made when the document was in production or had already been printed. They include insertions of new words or letters and deletions and interchanges of certain letters or words.

Forensic examiners use magnification, infrared imaging, and other tools to detect:

Erasures or Scratches: Any scratches on the paper can be the evidence of someone’s trying to erase or rewrite something to interfere with the characters.

Ink Color and Density: If certain letters or words appear in a slightly different shade, it can be used as evidence that the typewriter may have been changed at some point, or that a different ribbon was used, and so on.

Misaligned Characters: If letters appear to be offset relative to the rest of the page, this means it was done at a different time.

Knowing these signs can help collectors to present evidence that the item in question is fake or had been tampered with after creation.


Analyzing Typewriter Ribbons

Typewritten documents created by inked ribbons may reveal a lot by observing the inked ribbon used. If available, one may be able to get typewriter ribbons that will give an impression of letters recently typed and could sometimes form evidential value.

Matching Ribbon Impressions to Documents: By examining the impressions left on the ribbon, FDEs can often match the letters or words to a specific document, confirming it was typed on the machine in question.

Ribbon Wear: Older ribbons with faded sections indicate wear patterns that, in turn, will allow the examiners to get more acquainted with the age and workload of a specific typewriter.


Utilizing Advanced Imaging Techniques

In complicated situations, FDEs could employ different imaging that will help to investigate some facts that cannot be seen with the naked eye. These techniques include:

Infrared and Ultraviolet (UV) Imaging: They can be used to see marks that have been erased, written over, or written in invisible ink that cannot be seen under ordinary light.

Microscopic Analysis: High magnification tools enable examiners to look deeper into certain areas of the print for features impossible to see even with lenses; these may include fiber distortion from pressure from the typewriter or differences in ink density.

Electrostatic Detection: This technique looks for identifying the indented impressions on the underlying sheet beneath the top sheet, which is extremely helpful when many pages are typed at once.

Such techniques enable the forensic document examiners to expose signs of tampering or obliterated writing or text.


Compiling Evidence and Forming Conclusions

Following the examination, forensic document examiners prepare a document that contains information that they arrived at after examining the documents in question. This report usually includes:

  • Identification of the model of the typewriter and its features.
  • Font type and size, spaces between lines/paragraphs, alignment, and other unique features thereof.
  • Alterations, if any, and the techniques applied to detect them.
  • An overall conclusion on whether the document appears to be authentic or has signs of tampering.

Sometimes, FDEs are required to testify on these findings in court, where their testimony can influence the case’s outcome. A well-documented report with clear, evidence-based conclusions can significantly strengthen a legal case.


The Importance of Forensic Document Examination in Legal Cases

Typewritten documents are often key pieces of evidence in legal disputes. Documents can also contain valuable information, and all relevant knowledge can give an understanding of whether this document was produced naturally or was tampered with. In cases involving wills, contracts, or other legal documents, forensic document examination can prove instrumental in determining the legitimacy of claims.

Through advanced techniques and specialized expertise, forensic document examiners bring clarity to complex cases involving typewritten evidence. Their role ensures that justice can be served by verifying the authenticity of documents used in legal proceedings.

In forensic sciences, the oldest and simplest method of typewritten document examination is still carried out and plays an important role in discovering falsehood in writings and also maintaining the integrity of investigative and legal processes.


Conclusion

Typewritten documents present challenges to forensic document examiners in revealing the truths behind typed documents in which they apply technical knowledge, tools, and fine distinction. By comparing typefaces, alignment, ink deposition, and the likelihood of alteration, they can tell whether a document is genuine or whether it has been tampered with.

Specifically in legal and investigative fields, the forensic document examiners are quite useful since they can tell much about a document. Their work may be the thin line between authenticating a document as genuine evidence or denying it as a fake piece. The work that is done in such a manner not only assists in solving disputes and fraud-related cases but also in maintaining the legal documents and records with integrity in order to give justice on the basis of evidence.
