What it is

Rag paper sized with animal gelatine, beaten with water-powered hammers and marked with watermarks, able to take ink without bleeding. A Fabriano innovation that, once widespread in the 15th–16th centuries, made mass publishing viable.

Fabriano had introduced the watermark and animal sizing as early as the late 13th century; their industrial spread came in the 15th–16th centuries.

What it led to

  • A cheap, abundant supply for the printing press
  • The identification of manufacturers and quality control through watermarks
  • Large water-powered paper mills in France, Germany and the Netherlands
