IFRA, founded in 1961 as the INCA (International Newspaper Colour Association) when European publishers began to introduce the use of colour in newspapers, was the world's leading association for newspaper and media publishing. Based in Darmstadt, Hessen, Germany, more than 3000 publishing companies and suppliers to the publishing industry were members of IFRA. It changed its name in 1970 to IFRA and merged with the World Association of Newspapers in 2009.
