Forensic science is extremely exciting! With a degree in forensic science, graduates can also play an important role in the criminal justice system. Forensic science is a field that, through the use of chemistry, physics and biology, involves acknowledging, identifying, and analyzing physical evidence. Forensic science has become a vital part of the judicial system because its wide use of sciences helps law enforcement obtain information relevant to legal and criminal evidence.

But this technique is also able to overcome other stumbling blocks relating to the amount of ink deposited when writing and the type of paper used, as these variables hamper the dating of a document by means of traditional methods. What is more, the new technique reduces the number of punctures needed to analyse the writing on a document to just one. Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used. Until now, document dating methods have been able to indicate whether the writing was relatively new less than 90 days or older over two years , yet this chronological accuracy is insufficient in certain cases, above all in judicial ones. Each document was produced at different moments using a different ink stroke pressure, factors that may alter the results and lead to dating errors. During the natural ageing process of each sample, which had a known age, the research team analysed the evolution in the various volatile components.

Categories best inks dating sites. Questioned material science consist of identification cards, contracts, wills, titles and deeds, seals, stamps, bank checks, handwritten correspondence, machine-generated documents such as those from photocopiers, fax machines, and printers , currency and electronic documents. In some circumstances, graffiti and document fine may be examined; however, the client should be aware that the examination of these types of evidence tuned be problematic. Even documents that were shredded or burned may prove useful if reconstructed. In the documents, evidence could even be culled from the metadata of electronic signature files, providing information such as forensic the author is and when the document was written.
When did you make your book entries? When was the settlement signed? When was the will made? These are often very tricky questions to answer and frequently arise in judicial contexts. In fact, the dating of documents is a key area in the field of forensic science.
