Laid finish refers to the imprint of regular screen pattern of a papermaker's mould.
The laid effect creates a toothy grain of close lines on one side and a mottled surface on the reverse.
Ingres paper is favored in book arts for its antique appearance and pH neutrality.
Prominent manufactures include Canson, Hahnemühle (sometimes called "German Ingres"), and Fabriano.
Ingres paper has a high rag content (around 65%) and is gelatin sized.
