Some pages about Paper Watermarks and its collecting. What is a watermark in paper? Watermarks are designs or patterns put into paper during its production, by making thinner (line or wire watermarks) or thicker (shadow watermarks) the layer of pulp when it is still wet. Hence, the name. Paper watermarks can be seen holding the paper against the light or, in some cases, over a black surfece. Usually, they show the manufacturers's name, and geometric designs, or images of animals, etc.
The single-line watermarks used for United States stamps between 1910 and 1916 can be extremely difficult to find. This watermark pattern consists of the letters USPS repeated across the sheet and many stamps have only a small portion of one or two of the letters. A partial U or P might appear as just a thin line towards the edge of a stamp. Watermarks are best viewed from the back of the stamp. The basic method of watermark detection is to place the stamp face down in a specially manufactured black plastic tray, and place a few drops of watermark fluid on the stamp.
