5 Key Takeaways on the Road to Dominating
There are several ways in which one can get some clues to the analysis of a document’s forensic such as checking the ink and paper that have been used among some others. You can get different mechanical devices that you can use to do some forensic document analysis that you might be interested in. most times, printers, copiers as well as typewriters leave some markings on the document that has been typed or copied. Those markings can show that the papers have been tampered with. Those are the alterations that can be used by forensic document examiners to identify the kind of machine that was used to create the document. This article will provide you with information about how forensic document analysis is done by analysis ts when checking any printed document which may be needed in case of a crime.
Most offenders may either use a pencil or pen to write on paper. They may also choose to write ransom notes or intimidation letters using typewriters. Often times, perpetrators think that the letter they write using such may not be traced or noted. That is not true. It is possible for a forensic document analyst to analyze document that has been written using a typewriter. What the analyst does is finding out the model of the typewriter that has been used by the offender and also making a comparison with the notes that the suspected typewriter has made. The analyst needs to be able to get different typefaces that may have been used in the typewriters of both the new and old models. That information will come in handy when the forensic document analyst is trying to get the answers that they may be looking for.
For most of the typewriting machines that are available in the market, they use either elite or pica typefaces. They however have different shapes, sizes and the letter styles and that makes the analyst’s job quite difficult for them. It is however possible for the analyst to know the model and make of the typewriter that has been used to create a certain document after careful research. That may help the analyst have a shorter list of the particular machine that may have been used for the creation of the document in question. Most of the printers that are used these days use ink-jet, daisy-wheel, laser printing or dot-matrix technologies.
There is quite a difference in the printers and that may make the analyst spend more time before they have known the difference that they have. What the forensic document analyst does for them to know whether a certain typewriting machine was used for the creation of a document that is in question is searching for characteristics that are different from all others. The characters may be in form of letters that have been damaged or letters that have been spaced inconsistently either before or after certain letters. The letters used may also be slanting on a certain side. The abnormalities may be taken and compared to the sample page that has been created by the typewriter being suspected which will then provide some individualization qualities that can only be done by that typewriter.
