Branded columns are very impressive image making graphic elements.
Excellent working is their as if "free" positioning in the room and also their height that makes them visible above participants heads even when crowded.
The columns are surrounded with printed light Kapa boards and that is done in almost seamless way. Optimal height is up to 244cm, maximum is 300cm.
A cheaper alternative that can be used even outside is to wrap the column with printed PVC banner. This way the perimeter of the graphic must be the same as the column itself. Reasonable maximum height is about 400cm.
