For example, a questioned document that purports to have been executed in 2001 may contain a watermark that, after research, proves that the paper was not made until 2012.
Make a distinctive impression with your own watermarked papers.
Watermarks are designs or patterns put into the paper when it is made, by making thinner (line or wire watermarks) or thicker (shadow watermarks) adjustments to the layer of pulp when it is wet.
The object of watermarks in paper is, essentialy, identifying the paper, as a signature of the manufacturer, or as a security measure to avoid forgery of important documents such as bank notes, invoices, passports, entry tickets, etc.
Watermarks in the past have generally been reserved for large corporations with large budget.
