Jointly held by finishing specialists Duplo, Friedheim and Renz, the event will feature the UK debut of the DC-745 multifunction finishing machine, which will also be the first DC-745e to be shown anywhere in the world.
Also making its debut will be the PUR version of Friedheim's Tecnograf ANT 25 compact, semi-automatic single clamp perfect binder.
Other machines on show will include Renz's Mobi 500 binder and the latest EskoArtwork iXe-10 digital die cutter.
The event will run on 21-22 September and will have a 3D theme, so has been renamed London Calling 3D.
Visitors will be able to walk through a finishing trail, covering the products on show.
Duplo UK managing director Tony Lock said: "We will be completely taking over the Imax. We had around 100 companies visit last time around, up from 60 at London Calling – we are targeting more than 150 companies this time; I would expect some really big hitters to be in attendance."
