Papermaking at Fabriano mills began in 1283 and the remaining examples of paper that exist from this time indicate the advanced state of papermaking at the mills. Fabriano is responsible for the development of many innovations that are still a part of papermaking today, the most important of which is the identification of papers using watermarks. Artists and writers such as Albrecht Drer, Michelangelo, Raphael and Francisco Goya have praised Fabriano papers for their unequaled quality. Works from these artists that exist today are a testament to the enduring quality of Fabriano paper. Fabriano is the only papermaker that continues to employ both traditional and hi-tech production methods in its dedication to high quality artist paper.
