The Jemseby method is a patented photographic reproduction method invented by Anton Jemseby in the 1940s and subsequently developed and refined by Anton's son, co-applicant in this application, Bo Jemseby. The Jemseby method was used in the 1970s by more than 50 companies in Sweden, Norway, Germany, Austria, England, Australia, Kuwait, Iraq, Bhutan and Portugal. Today, the development of the graphic industry has eliminated the method, but in the graphic arts business the craft is still alive and well. I, Peter Ragnarsson, came into contact with Bo as a printer and graphic designer in 1984 and have since then done my own repro and produced several acclaimed art and photo books using the Jemseby method. Among the more famous are Tomtebobarnen by Elsa Beskov and Svenskt fågellexikon from 1984. Over the years, Bo Jemseby has sketched a book about the method and his own professional graphic life with it. I am now helping Bo, in my role as editor and ghost writer, to ensure that we can complete his book together. The goal is a technical-historical and richly illustrated book with Bo Jemseby and the Jemseby method at the center.
