Documents of all kinds have been accompanying mankind since the dawn of history. A large part of communication around the world is based on documents.
There are documents everywhere people know how to read and write.
Every document consists of two components:
» The substrate on which it is written.
» The written or printed material.
In the course of time, there was development both in regard to the material the substrate is made of (from stone and clay tablets via papyrus to paper) and the utensils used for writing (a number of different kinds of pens, different kinds of ink and a number of ways to print).
A forensic examination of documents checks the parameters characteristic to the document in question and makes it possible to reach the following conclusions:
» The date of creation
» Additions to the document
» Editing of the document
These parameters enable us to reach conclusions in regard to the document’s authenticity and the way it passed until it reached its final state.
