GAE will be inviting existing and potential customers to look around its Perivale HQ on 7-9 July.
The latest companies to confirm attendance are Murodigital, Andersons and Esko Artwork – completing the pre-press, press and post-press line-up.
Machines on show will include the debut of Renz's AB500, which was launched at Northprint.
GAE highlighted the Plockmatic 4000 direct mail inserting system, which comprises the MF 4000 Mailfeeder, TF 4000 Towerfeeder, BF 4000 Bookletfeeder, MFF 4000 Multifunction folder, DMI 4000 Inserter and BST 4000 Beltstacker.
Adrian Brooks, national products manager for Murodigital, said: "This is a unique system as it can handle DL, C5, C4 and custom sizes. Normally, a production unit has one of those options and ones with more than that can be double the price.
"The ability to offer a range of options creates added flexibility for printers as they can easily switch from short-run jobs. It is ideal for print-on-demand with the benefit of being very simple to set up and minimal operator training is required."
