Next year's show is set to take place on 27-29 March at Birmingham's NEC and comes on the back of this year's event, which had a 22% increase in visitors compared to the previous show.
Companies that have already signed up include HP, Digital Print Innovations (DPI), EskoArtwork, William Smith, Drytac, and InkTec.
Rudi Blackett, show director Sign & Digital UK, said: "We’re very pleased with the results from the 2011 show. We knew it was busy and the buzz surrounding it and during the actual event was palpable.
"It’s up to us as organisers to work with the leading industry suppliers and educators to build on this success and deliver a show in 2012 that’s fit for an Olympic year – and so far, with the exhibitors that have booked and that are in the process of booking we are getting close to that."
