Non-Watermarked Paper

The "classic" stamp watermark is a small crown or other national symbol, appearing either once on each stamp or a continuous pattern. Some types of embossing, such as that used to make the "cross on oval" design on early stamps of Switzerland, resemble a watermark in that the paper is thinner, but can be distinguished by having sharper edges than is usual for a normal watermark.Watermarks were nearly universal on stamps in the 19th and early 20th centuries, but generally fell out of use and are not commonly used on modern U. Stamp paper watermarks also show various designs, letters, numbers and pictorial elements.It is a shaded watermark first used in 1848 that incorporates tonal depth and creates a greyscale image.Instead of using a wire covering for the dandy roll, the shaded watermark is created by areas of relief on the roll's own surface.Various aids have been developed, such as watermark fluid that wets the paper without damaging it.A watermark is very useful in the examination of paper because it can be used for dating, identifying sizes, mill trademarks and locations, and determining the quality of a sheet of paper.A watermark is an identifying image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness or density variations in the paper.
