As the paper pulp drained, this device would be imprinted in the paper along with the lines of the wire mesh. When one of the matching filigrees or molds A or B broke while the other was still in good condition, a replacement mold or filigree might be made Cso that the pair A-B became the pair A-C or B-C.
Significance of Other Physical Features of Paper Establishing that one paper matches another is not easy, given the intentional similarity among watermarks, the short life-span of any one filigree, the the liklihood that it would be replaced by a new one made to look like the first.
Are there watermarks which are solely tied to one area. All of these early papers were unwatermarked; they are recognizable from other physical characteristics such as color, consistency and characteristic patterns of the lines visible in the paper.

Because the patterned portion of the page is thinner, it transmits more light through and therefore has a lighter appearance than the surrounding paper.
Are there some general pointers about century and place. Paraded Two or more watermarks and sometimes a portion of a third appear on each sheet. Consequently, watermarks are usually found in matched pairs, identified in this archive by the suffixes a and b in the paper reference numbers.
The wire profile also includes any watermarks or countermarks present in the sheet. The IV initials were very common as a countermark in English-made paper.
Collectors who encounter two otherwise identical stamps with different watermarks consider each stamp to be a separate identifiable issue. Can be produced in weights ranging from 20 lb. These were papers of Arabic manufacture, which were gradually replaced by the earliest Italian papers and in some places paper of Catalan manufacture.
The sixteenth-century Philotheite scribe, Gabriel of Kallioupolis Gallipolifor example, brushed a glaze onto the papers he used before he assembled his books, in order to prepare the pages for his extensive illumination.
The superior formation and uniformity of which premium papers from Neenah are known - ensure that the watermark appears crisp and clean. And then - judgoing from the papers being produced at this point in time they appeared to be triplets Because the chain wires are located on the outside of the laid wires, they have a greater influence on the impression in the pulp, hence their bolder appearance than the laid wire lines.
Staggered Staggered watermarks are produced in the same manner as paraded marks, but usually in a diagonal relationship.
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. As a rule, the lighter the paper, the more visible the watermark.

Whatman paper was faked in Germany. Sometimes a watermark in stamp paper can be seen just by looking at the unprinted back side of a stamp. It is an extension of your corporate image. Successful watermarks will be faked or imitated in other areas, but generally they can be broken up on national lines.

If you follow me on Instagram you may have seen this intriguing watermark in my first edition of Nehemiah Grew's The Anatomy of Vegetables Begun, the first work of scientific botany.
Watermarks are often obscured under text, but in this case I was lucky, as it happened to coincide with the blank portion of a folding plate. A watermark can be a date, name, or design device made of copper or brass wire incorporated in the paper making tray which produces an impression in “the pulp as it settles during the process of papermaking, and is visible in the finished product when held against the light” (John Carter).
A Private Watermark provides both security and authenticity. It cannot be removed, altered or duplicated. It is a permanent part of the 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.
I was able to put some questions about paper and watermarks to Neil Harris and Peter Bower. Professor Harris is the Director of the Department of History and Conservation of the Cultural Heritage at the University of Udine, where he teaches courses in Bibliography and Library Science.
Watermarks are designs set into a sheet of paper during the papermaking process when it is first formed and wet. The thickness and thinness of the sheet is manipulated, resulting in a hidden image only revealed when held up to a light source.Paper and watermarks
