In 1990, imprints began printing and publishing portfolios of prints, at first under the separate imprint Ka! Editions and now simply as imprints. Initially the idea was to produce portfolios in the “mappenwerk” tradition that was concurrent with the “livres d’artiste” publications of the 20th century. It was soon apparent that some artists wanted to make single prints and therefore imprints began making individual works as well.

imprints print publications have been acquired by many major print collections around the World and Matthew Tyson is considered one of the leading maître imprimeurs specialising in relief printing.
