Not only is the ink from a ballpoint pen, not the type of paper provide clues for analysts legal document about the origin of a questionable document, many types of mechanical devices to do this. Photocopiers, printers and typewriters often leave marks on the specific item to be inserted or copied. These markings may show that a particular piece of paper has changed. Such changes can identify the examiners legal document exactly which machine created the respondentsDocument.
In this article I will try to explain what analysts look if they have a legal document printed document, as used in the commission of a crime to occur.
If you do not use paper and pen, typewriter letters, often the perpetrators of intimidation or redemption, write notes. Authors are often false sense of security that such an act, which makes the letter, or no longer be located. Nothing could be further from the truth. Ifa typewriter used to create a document of questionable, the document seeks to forensic analyst

Determine the make and model of a typewriter, it means that forensic document analysts have used to access a list of characters in different models of typewriters, old and new. Many manufacturers use the elite or pica typewriter font. However, the size, shape and styleThe letters are different, so that analysts, the difficult task. After a thorough examination of a document typed by the analyst may be able to discover the make and model of typewriter that created it. This can help shorten the precise list of machines that created the document. On the other hand, the current use daisy wheel printers, inkjet, varying matrix or laser printing technologies. These printers easily, so that analysts can not view the document, often,other.
To determine whether a particular machine, a document of dubious forensic document analyst in search of unique properties that are not connected properly or damaged letters, the spaces created conflict before or after a few letters and inconsistent pressure on the side of some letters. For example, some letters of cavities or passages that can be printed on a sheet of paper. These letters may also be inclined to release orslightly higher or lower than the rest of the letters on the page. These changes may be made in relation to a sample page from a suspicious car, creating a strong individual qualities that are unique only to this machine.
To draw a comparison between a document called into question and a particular machine, the forensic analyst, document types, document comparison from the typewriter suspicion. During this, an analyst uses a band that similarlyCondition of people who used to create the original document. The reason is that a belt worn minor anomalies are found in Scripture. On the other hand, a new band with fresh ink, you can hide.
Typing machines, bands in the analyst forensic document corresponds to a particular machine to help the document. If a typewriter with a single-pass band, forensic scientists can only read the message of the bandThe band is still in the car. Although the group has been used several times, the police may still be part of the message by the group.
Suppose that a scammer using the original machine to include an additional line or a paragraph in a document? As the forensic document examiner does not consider that this has happened? If Scripture is both the original text, and the added value that is identical to the text, it is difficult for the examiner to determine whether a changeoccurred. But if the paper into a typewriter used for the second time, attention is often turned off. Advantage of this fact that the examiner is a specially formulated glass with a grid etched on the page. So you can easily see discrepancies in the alignment of lines and extra points.
