Menphis decorated the doors of the rooms in the Nhow Milano Hotel with graffiti patterned aluminium panels, revealing the great emotional impact of transfer technology serving design. Menphis brings transfer technology into the hotel. Architect Matteo Thun created the interior design of the Nhow, a 4 star hotel in Milan's Via Tortona operated by the NH Hotels chain, and the graphic design on the doors of all the hotel's 249 rooms on four floors. The doors, arranged in pairs, are the key element creating the atmosphere in the hotel's long corridors. The doors are made of two paired elements: an outer panel featuring a white graffiti design against a black background, and the wooden door itself. The outer panel was made by Menphis reproducing Thun's design based on the graffiti on the nearby iron bridge at Porta Genova railway station on aluminium panels. The aluminium substrate was treated with thermosetting polyester powder suitable for sublimation, a process which uses high temperatures to transfer the design on the polyester film to be applied to the panel. The procedure employs special presses which, when heated to a temperature of 200°C, promote perfect contact of the film with the surface to be treated.
