Current obsession: watermarks! Iowa Center for the Book papermaking facility; above right: the resulting sheet of handmade paper with backlit watermark visible]. If you are not familiar with the process of hand papermaking, here is a look at a paper production at a mill in Maidstone, Kent, England [Hayle Mill, run by Barcham Green and family]. Another video poetically describes a papermaking mill in Puymoyen [southwest France, the region of Nouvelle-Aquitaine]. If I were a scribe in 15th-c. Though an individual mould only lasted about a year [in full production], a watermark symbol was remade again and again on new moulds associated with a given paper mill. Watermarks also wore out over the course of a year, changing slightly in shape and definition. More on the book in a future post!
The watermark is not a modern innovation, nor was it created to prevent counterfeiting. It was a medieval creation, one used primarily to show the maker of the paper, but also the place in which the paper was made, and less often when the paper was made. For this blog, I would like to discuss the risks of this third purpose of medieval watermarking- using watermarking as a means to date paper.
5thInternational conference on watermarks in digital collections, Bernstein tools for undertaking paper expertises (image processing, measurements, dating).
Watermarks vary greatly in their visibility; while some are obvious on casual inspection, others require some study to pick out. Various aids have dating developed, such as watermark learning that wets the paper without damaging it. A watermark is very useful in the paper of paper because it watermarks be used for dating, identifying sizes, mill trademarks and locations, and determining the quality of a sheet of paper.
The word is also used dating digital practices that share similarities with physical watermarks. In one case, overprint watermarks computer-printed output may be used to identify output watermarks an unlicensed trial version of a program. In another instance, identifying codes can be encoded as a digital watermark for a music , video , picture , or other file.
The origin of the water part of a watermark can be found back when a watermark was something that only existed in paper. Watermarks were first introduced in Fabriano , Italy , in. Traditionally, a learning was made by impressing a water-coated metal stamp watermarks dandy roll onto the paper watermarks manufacturing.
Learning to “read” old paper
Although paper came already in the fifteenth century to Iceland, we do not know where it was produced or who sold it. Paper came in the fifteenth century to Iceland but was used sparingly in the beginning, it seems, as there are only very few extant paper manuscripts or documents from that century. Paper was used mostly for ephemeral and unimportant texts, such as drafts and letters, until people were certain of its durability, which took a while: paper supplanted parchment in the late sixteenth century, judging from numbers of extant paper manuscripts in comparison to extant parchment manuscripts.
Paper had to be imported, though, because there were no paper mills in Iceland. We do not know where it was produced nor how it came to Iceland.

There are two main ways of producing watermarks in paper; the dandy roll process , and the more complex cylinder mould process. Watermarks vary greatly in their visibility; while some are obvious on casual inspection, others require some study to pick out. 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.
The word is also used for digital practices that share similarities with physical watermarks. In one case, overprint on computer-printed output may be used to identify output from an unlicensed trial version of a program.

Until halfway the twentieth century, watermarks were reproduced with tracings. The two methods here used for the Low Countries incunabula are rubbings and electron radiography. Making rubbings is cheap and quick and does not damage the books. The best images of watermarks are made by beta radiography and electron radiography. Because of the slowness of beta radiography – a single image can take hours to capture – electron radiography is preferable.
The first electron radiographs of watermarks in Low Countries incunabula were taken from more than dated folio editions in the collection of the Koninklijke Bibliotheek the total of dated incunabula from the Low Countries in folio format is less than There are also a few images of watermarks found in quartos by the Printer of the Freeska Landriucht e. Then part of the image, placed as it is on two leaves, is lost in the gutter of a bound volume. The total of records is more than In WILC, more specific search possibilities for incunabula are offered.

It is mainly used for documents whose authenticity is important and to produce other papers in which it forms a decorative element. In the past, paper mills used watermarks as their seal to trace paper origin and quality. You could say that they were used like logos are today. These characters are basic and simple. In the 19th century, a process of paper production with cylinder mould was developed, where the paper itself is formed on a circular sieve.
The development of this process made it possible to produce an embossed watermark that is imprinted in the sieve itself. Protected security paper incorporates various security features that prove the authenticity of the material and prevent falsification of documents. These elements can be seen in daylight or UV light. They are integrated into the paper in such a way that it is practically impossible to remove them without damaging the surface of the base material.
Most security papers also have a watermark. Its design and complexity are tailored to the end product and customer requirements. The preparation and production of the watermark itself has changed a lot.
Southworth has been using date codes on most of our watermarked grades since at least The reason for the date code is so that Southworth can tell what year the paper was made. Southworth has received numerous calls asking if we can determine when a particular sheet of our paper was made. On approximately half of the calls we receive, we identify that the paper was made after the document states it was written.
One of the calls that Southworth received was from Mr. Marvin H.
Paper research can – as can printing type – provide a dating within a range of years rather than decades. Identification of paper stocks however, has long been.
Watermarks are designs embedded in paper. Used at least since the medieval period, they are created during the papermaking process by forming wires into a unique decorative pattern in the sieve-like mold that holds the pulp from which paper is made. Possibly used by papermakers as an early branding device, they only become visible in transmitted light. Modern-day versions of watermarks are still used in some paper objects, such as official government documents, and can serve to authenticate them.
It remains unclear what the exact purpose of these intricate marks was initially, however, they are now widely used by scholars to provide estimated dates for works on paper and even clues about their regions of origin. While watermarks prove to be helpful in assessing when and where a certain artwork was created, their evidential value remains limited. The fact that paper was often stored and transported means that the same watermark can be found in artworks with divergent dates and places of origin.
The first is a well-known one: the foolscap with five-pointed collar. This watermark has been documented in collections around the world. Through comparison with other examples, a two similar watermarks were identified in sheets of paper dated to ca.
